It cost 3 times more to feed a cat per week than than it does a rabbit per week and half as much to feed a hamster per week than it to feed a rabbit per week. If it cost $2.00 to feed a hamster per week, how much does it cost to feed a cat for 3 weeks

A. $9.00

B. $48.00

C. $36.00

D. $84.00

E. $25.00

F. $12.00

Answers

Answer 1
The answer is C, or $36.00. Why? Well, if it costs $2.00 to feed a hamster per week, that means it costs $4.00 to feed a rabbit per week. Since a rabbit’s food costs $4.00 per week, that would mean it costs $12.00 to feed a cat per week. Because 12 x 3 = 36, it costs a total of $36.00 to feed a cat for 3 weeks.

Your final answer: C, or $36.00.

At the beginning of the first day of the experiment the mass of the substance was 1300 grams and mass was decreasing by 14% per day. Determine the mass of the radioactive sample at the beginning of the 11th day of the experiment.

Answers

The mass of the radioactive sample at the beginning of the 11th day of the experiment is approximately 286 grams.

How to find the mass?

Since the mass is decreasing by 14% per day, we can find the mass at the beginning of each day by multiplying the previous day's mass by 0.86 (which is 100% - 14%).

At the beginning of the first day, the mass was 1300 grams.

At the beginning of the second day, the mass is:

1300 grams x 0.86 = 1118 grams (rounded to the nearest gram)

At the beginning of the third day, the mass is:

1118 grams x 0.86 = 962 grams (rounded to the nearest gram)

We can continue this pattern to find the mass at the beginning of the 11th day:

Mass at the beginning of the fourth day: 962 grams x 0.86 = 828 grams

Mass at the beginning of the fifth day: 828 grams x 0.86 = 711 grams

Mass at the beginning of the sixth day: 711 grams x 0.86 = 612 grams

Mass at the beginning of the seventh day: 612 grams x 0.86 = 526 grams

Mass at the beginning of the eighth day: 526 grams x 0.86 = 452 grams

Mass at the beginning of the ninth day: 452 grams x 0.86 = 388 grams

Mass at the beginning of the tenth day: 388 grams x 0.86 = 333 grams

Mass at the beginning of the eleventh day: 333 grams x 0.86 = 286 grams (rounded to the nearest gram)

Therefore, the mass of the radioactive sample at the beginning of the 11th day of the experiment is approximately 286 grams.

Find a parametrization of the line in which the planes x + y + z = 9 and y + z = 3 intersect. Find the parametrization of the line. Let z = t. X=. Y=0,2=0 -Oz-| -00

Answers

This parametrization allows you to express any point on the line by choosing a value for the parameter t.

From the equation y + z = 3, we can express y in terms of z as y = 3 - z.

Substituting this expression for y into the equation x + y + z = 9, we have x + (3 - z) + z = 9.

Simplifying, we get x + 3 = 9.

Rearranging the equation, we have x = 6.

Now we have the following parametrization:

x = 6

y = 3 - z

z = t

where t is a parameter representing the value of z.

Thus, the parametrization of the line formed by the intersection of the planes x + y + z = 9 and y + z = 3 is:

x = 6,

y = 3 - t,

z = t.

This parametrization allows you to express any point on the line by choosing a value for the parameter t.

The possible outcomes should have a head in its third and fifth tosses is 219, according to the question.

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

According to the given question,

We can toss it 8 times,

Exactly three heads (hence, exactly 5 tails), no fewer, no more. So there are eight coins, and we need to compute how many ways we can choose three to be heads:

(83)=8!/3!5!=56

At least three heads (hence, at most 5 tails): here we count sequences with exactly 3 heads, and also count sequences with more than three heads. What doesn't count are those sequences containing (zero heads, exactly one head, or exactly two heads). We could compute this as

(83)+(84)+⋯+(88)

But it would be far easier to compute its equivalent, by subtracting from 256 the number of sequences with no head, only one head, and only 2 heads:

256−((8/0)+(8/1)+(8/2))=256−(1+8+28)=219

Therefore, the possible outcomes should have a head in its third and fifth tosses is 219.

Determine all values of h and f for which the system x + 3y = h and -4x + ky = -9 has no solution.

Answers

For any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

To determine the values of h and okay for which the device of equations has no answer, we want to locate the situations underneath which the equations are inconsistent or parallel.

The given system of equations is:

Equation 1: x + 3y = h

Equation 2: -4x + ky = -9

For the gadget to haven't any answer, the lines represented with the aid of these equations should be parallel and in no way intersect. In different phrases, the slopes of the traces need to be equal, but the y-intercepts should be specific.

Let's first discover the slopes of the traces. The slope-intercept form of Equation 1 is y = (-1/3)x + (h/3), wherein the slope is -1/3. The slope-intercept shape of Equation 2 is y = (4/k)x - (9/k), wherein the slope is 4/k.

For the strains to be parallel, the slopes should be equal. Therefore, we have the condition: -1/3 = 4/k.

To locate the values of h and okay for which the gadget has no answer, we need to locate the values of h that satisfy the situation -1/3 = 4/k.

Solving this equation for ok, we've got:

-1/3 = 4/k

-1 = 12/k

k = -12

Substituting k = -12 returned into the equation -1/3 = 4/k, we've:

-1/3 = 4/(-12)

-1/3 = -1/3

Since the equation holds real for any value of h, there aren't any restrictions at the price of h.

Therefore, for any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

The system of equations has no solution when k is equal to 12. The value of h can be any real number.

To determine the values of h and f for which the system has no solution, we need to analyze the coefficients of the variables and the constants in the equations.

The given system of equations is:

x + 3y = h

-4x + ky = -9

We can rewrite the second equation as:

-4x + ky = -9

Dividing both sides of the equation by -4, we get:

x - (k/4)y = 9/4

Comparing the coefficients of x and y in the two equations, we can see that the slopes of the lines represented by the equations are different when k is not equal to 12.

Therefore, for the system to have no solution, k must be equal to 12.

Find a linear function h given h(-1)=-2 and h(-7)=-9 The linear function is h(x)= (Simplify your answer. Use integers or fractions for any numbers in the expression.)

Answers

h(x) = -7/6x - 25/6.

Given h(-1)=-2 and h(-7)=-9

For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.

To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

h(-1) = -2 is a point on the line, so we can write it as (-1, -2).

h(-7) = -9 is another point on the line, so we can write it as (-7, -9).

Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6

Now we can find b using one of the points and m. Let's use (-1, -2):

y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b

b = -25/6

Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6

We can check our answer by plugging in the two given points:

h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9

The answer is h(x) = -7/6x - 25/6.

Use the table to answer the questions No Birth Control Birth Control No BRCA Gene 20 30 BRCA Gene 50 ? Using the additive model what value would we expect in cell d? 50 O 60 30 40

Answers

The distribution of individuals based on two factors: the presence or absence of birth control (rows) and the presence or absence of the BRCA gene (columns). The numbers in each cell represent the count of individuals falling into a specific category.

In the additive model, the values in the cells are independent of each other, and the expected count in any given cell is obtained by adding the row total and column total for that cell and subtracting the grand total. The formula for the additive model is:

Expected count in cell = (Row total * Column total) / Grand total

We are given the values for cells a, b, and c. Using the provided table, we can calculate the row and column totals:

Row total for row 1 (No Birth Control) = 20 + 30 = 50

Row total for row 2 (Birth Control) = 50 + x (value in cell d)

Column total for column 1 (No BRCA Gene) = 20 + 50 = 70

Column total for column 2 (BRCA Gene) = 30 + x (value in cell d)

Grand total = 20 + 30 + 50 + x (values in all cells)

Now, let's substitute these values into the additive model formula:

(50 * (30 + x)) / (20 + 30 + 50 + x) = 50

Next, we can cross-multiply and solve for x:

50 * (30 + x) = 50 * (100 + x)

1500 + 50x = 5000 + 50x

By canceling out the 50x terms on both sides, we get:

1500 = 5000

However, this equation has no solution. It indicates that the given table is not consistent with the additive model. Consequently, we cannot determine the expected value in cell d using the additive model with the provided information.

Maria, Aldo, and Boris sent a total of 102 text messages over their cell phones during the weekend. Aldo sent 2 times as many messages as Boris. Boris sent 10 fewer messages than Maria. How many messages did they each send?

Answers

Maria sent 28 messages. Aldo sent 46 messages. Maria, Aldo, and Boris sent a total of 102 text messages over their cell phones during the weekend.

Let's start by assigning variables to represent the unknowns in the problem. Let A be the number of messages Aldo sent, B be the number of messages Boris sent, and M be the number of messages Maria sent. We can use the information given in the problem to form a system of equations:

A + B + M = 102   (total messages sent)

A = 2B           (Aldo sent twice as many as Boris)

B = M - 10        (Boris sent 10 fewer than Maria)

We can substitute the second equation into the third equation to get:

A = 2(M - 10)     (substitute B with M - 10)

Now we have two equations involving only A and M:

A + (M - 10) + M = 102    (substitute B with M - 10 in first equation)

A = 2(M - 10)            (substitute B with M - 10 in third equation)

We can simplify the first equation by combining like terms:

2M - 10 + A = 102

And we can simplify the second equation by distributing the 2:

A = 2M - 20

Now we have a system of two equations with two unknowns:

2M - 10 + A = 102

A = 2M - 20

We can solve for A in the second equation:

A = 2M - 20

A + 20 = 2M

M = (A + 20)/2

We can substitute this expression for M into the first equation:

2M - 10 + A = 102

2((A + 20)/2) - 10 + A = 102

A + 20 - 10 + A = 102

2A + 10 = 102

2A = 92

A = 46

So Aldo sent 46 messages. We can use the equation B = M - 10 to find Boris's number of messages:

B = M - 10

B = (A + 20)/2 - 10

B = (46 + 20)/2 - 10

B = 28

So Boris sent 28 messages. Finally, we can use the first equation to find Maria's number of messages:

A + B + M = 102

M = 102 - A - B

M = 102 - 46 - 28

M = 28

Therefore, Maria sent 28 messages.

a) The difference in the percentage of points won when serving and when the opponent is serving can be calculated by subtracting the percentage of points won when the opponent is serving from the percentage of points won when serving.  To find the percentage of points won when serving, we divide the number of points won when serving by the total number of points served by Samson and multiply by 100. Similarly, to find the percentage of points won when the opponent is serving, we divide the number of points won when the opponent is serving by the total number of points served by the opponent and multiply by 100.

b) The hypotheses we are interested in testing are:
- Null hypothesis (H0): There is no difference in Samson's performance when serving and when his opponent is serving.
- Alternative hypothesis (Ha): Samson performs better when serving compared to when his opponent is serving.

c) A p-value of 0.24 indicates that if the null hypothesis were true, there would be a 24% chance of observing a difference in performance as extreme as the one observed in the data. In other words, the p-value represents the probability of obtaining the observed difference in performance or a more extreme difference, assuming that there is no actual difference in Samson's performance when serving.

d) Based on the p-value of 0.24, we do not have strong evidence to reject the null hypothesis. This means that the data does not provide convincing evidence that Samson plays better when serving compared to when his opponent is serving.

e) If our conclusion from part d was in error, it would be a Type II error. This occurs when we fail to reject the null hypothesis even though it is false. In this case, it would mean that there is a difference in Samson's performance when serving, but we failed to detect it.

f) In the context of this question, a Type II error would mean that we concluded there is no difference in Samson's performance when serving and when his opponent is serving, but in reality, there is a difference. This could potentially lead to underestimating Samson's ability to perform better when serving.

g) To reduce the likelihood of a Type II error occurring, we can increase the sample size. By collecting more data, we can increase the power of our test and improve our ability to detect a difference in performance if it truly exists. Additionally, we can also adjust the significance level of our test (e.g., from 0.05 to 0.01) to make it more likely to detect smaller differences.

h) No, we cannot conclude that Samson's serving is the cause of the difference in his ability to win points when serving compared to when his opponent is serving. The data provided only shows an association between serving and winning points, but it does not establish a causal relationship. Other factors, such as skill, strategy, or the opponent's performance, could also contribute to the difference observed. To establish causality, further investigation and controlled experiments would be needed.

Find the general solution of the given differential equation and then find the specific solution satisfying the given initial conditions.
Y^2dy/dx − xy^3 = 2x given. y(0)=2

Answers

The general solution of the given differential equation is y = (x ± √(x^2 + 2e^2x)) / e^x, and the specific solution satisfying the initial condition y(0) = 2 is y = 0.

To solve the given differential equation, let's rewrite it in a more standard form:

y^2 * dy/dx - xy^3 = 2x

First, let's separate the variables by moving all the terms involving y to one side and all the terms involving x to the other side:

y^2 * dy - y^3 * dx = 2x * dx

Next, we divide both sides of the equation by y^2 * dx to isolate dy:

dy/dx - (y^3 / y^2) = (2x / y^2) * dx

Simplifying the expression on the left side:

dy/dx - y = (2x / y^2) * dx

Now, we can see that this is a first-order linear ordinary differential equation of the form dy/dx + P(x) * y = Q(x), where P(x) = -1 and Q(x) = (2x / y^2).

The integrating factor for this equation is given by exp(∫P(x)dx) = exp(-∫dx) = exp(-x) = 1/e^x.

Multiplying both sides of the equation by the integrating factor, we get:

(1/e^x) * dy/dx - (1/e^x) * y = (2x / y^2) * (1/e^x)

This can be rewritten as:

d/dx (y/e^x) = (2x / y^2) * (1/e^x)

Integrating both sides with respect to x, we obtain:

∫d/dx (y/e^x) dx = ∫(2x / y^2) * (1/e^x) dx

Integrating the left side gives us y/e^x, and integrating the right side requires integration by parts. Applying integration by parts once, we have:

y/e^x = ∫(2x / y^2) * (1/e^x) dx

       = -2∫x * (1/y^2) * (1/e^x) dx

       = -2 * (x * (-1/y^2) * (1/e^x) - ∫(-1/y^2) * (1/e^x) dx)

       = 2x/y^2 * (1/e^x) + 2∫(1/y^2) * (1/e^x) dx

Continuing with the integration by parts, we integrate ∫(1/y^2) * (1/e^x) dx:

y/e^x = 2x/y^2 * (1/e^x) + 2 * (1/y^2) * (1/e^x) - 2∫(d/dx(1/y^2)) * (1/e^x) dx

Differentiating 1/y^2 with respect to x, we get:

d/dx(1/y^2) = (-2/y^3) * (dy/dx)

Substituting this back into the equation, we have:

y/e^x = 2x/y^2 * (1/e^x) + 2 * (1/y^2) * (1/e^x) + 2∫(2/y^3) * (1/e^x) * (1/e^x) dx

Simplifying the equation further, we obtain:

y/e^x = 2x/y^2 * (1/e^x) + 2/y^2 * (1/e^x) + 2∫(2/y^3) *

(1/e^(2x)) dx

To solve the integral on the right side, we can make the substitution u = e^x:

du/dx = e^x

Rearranging the equation, we have dx = du/e^x = du/u.

Substituting u = e^x and dx = du/u into the integral, we get:

2∫(2/y^3) * (1/u^2) du

This integral can be easily evaluated as:

4∫(1/y^3u^2) du = -4/y^3u

Substituting u = e^x back into the equation, we have:

4∫(1/y^3e^2x) dx = -4/y^3e^x

Substituting this result back into the equation, we get:

y/e^x = 2x/y^2 * (1/e^x) + 2/y^2 * (1/e^x) - 4/y^3e^x

Combining the terms on the right side, we have:

y/e^x = (2x + 2 - 4/y) * (1/y^2) * (1/e^x)

Multiplying through by y^2 * e^x, we obtain:

y * e^x = (2x + 2 - 4/y) * (1/e^x)

Expanding the right side, we have:

y * e^x = (2x/e^x + 2/e^x - 4/y * 1/e^x)

Simplifying further:

y * e^x = 2x/e^x + 2 - 4/(y * e^x)

Now, let's solve for y. Multiplying through by y * e^x:

y^2 * e^x = 2xy + 2ye^x - 4

Rearranging the terms:

y^2 * e^x - 2xy - 2ye^x = -4

This is a quadratic equation in y. To solve for y, we can use the quadratic formula:

y = (-b ± √(b^2 - 4ac)) / 2a

Comparing the equation to the standard quadratic form, we have:

a = e^x

b = -2x

c = -2e^x

Substituting these values into the quadratic formula, we get:

y = (-(-2x) ± √((-2x)^2 - 4(e^x)(-2e^x))) / (2(e^x))

Simplifying further:

y = (2x ± √(4x^2 + 8e^2x)) / (2e^x)

  = (x ± √(x^2 + 2e^2x)) / e^x

This is the general solution of the given differential equation. Now, let's find the specific solution satisfying the initial condition y(0) = 2.

Substituting x = 0 into the general solution, we have:

y(0) = (0 ± √(0^2 + 2e^2*0)) / e^0

       = (0 ± √(0 + 0)) / 1

       = 0 ± 0

       = 0

Therefore, the specific solution satisfying the initial condition y(0) = 2 is y = 0.
