The total number of cards = 5 yellow. 3 blue and 7 red = 15 cards in all.

The probability of choosing a yellow card first is 5/15 = 1/3.

We are now down to 14 cards

There are 3 blue cards.

P(yellow then blue) = 1/3 * 3/14

Step-by-step explanation:

The equation 164² + 204 = 164-4x² - 4xy-4 represents a conic section known as an ellipse.

The given equation can be rewritten as 164² + 204 + 4x² + 4xy - 164 = 0 by rearranging the terms. Simplifying further, we have 4x² + 4xy + (164² - 164) + 204 = 0.

Comparing this equation with the general form of an ellipse, Ax² + Bxy + Cy² + Dx + Ey + F = 0, we can identify A = 4, B = 4, and C = 0. Since B² - 4AC = 4² - 4(4)(0) = 16 - 0 = 16 > 0, we can conclude that the given equation represents an ellipse.

To express the equation 2² = X² + xy in parametric form:

Let's introduce two new variables, u and v, which will be our parameters. We can express x and y in terms of u and v.

From the given equation, we have:

2² = X² + xy

Substituting x = u and y = v, we get:

2² = u² + uv

Now, we can express x and y in terms of u and v:

x = u

y = 2 - uv

Therefore, the parametric form of the equation 2² = X² + xy is:

x = u

y = 2 - uv

In this parametric form, we can choose various values for u and v to obtain different points on the curve represented by the equation.

The normal approximation is used to estimate probabilities in a medication study for weight gain as a side effect, providing insights into specific outcomes.

To approximate the probabilities using the normal approximation to the binomial, we need to know the success probability (percent of patients gaining weight) and the number of patients involved in the study. Let's denote the success probability as p and the number of patients as n.

(a) To calculate the probability that exactly k patients will gain weight, we can use the formula for the binomial distribution:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

However, since we are using the normal approximation, we can approximate it as:

P(X = k) ≈ P(k - 0.5 < X < k + 0.5)

(b) To calculate the probability that no more than k patients will gain weight, we can sum the probabilities from 0 to k:

P(X ≤ k) ≈ P(0.5 < X < k + 0.5)

(c) To calculate the probability that at least k patients will gain weight, we can subtract the probability of the complement event (less than k patients) from 1:

P(X ≥ k) ≈ 1 - P(X < k + 0.5)

These approximations rely on the assumption that n is sufficiently large and that p is not too close to 0 or 1. The result suggests that we can estimate the probabilities of specific outcomes in the medication study using the normal distribution, providing an approximate understanding of the likelihood of different scenarios.

John's savings amount as a function of time is S(t) = $24,000 / 25. Initially, he needs to save $24,000 for a new car. After the first month, he has saved $1,000. The savings amount is directly proportional to the time elapsed. The constant of proportionality is 1/24. Thus, John's savings amount can be determined based on the remaining amount he needs to save.

John's savings amount can be represented as a function of time and is proportional to the amount he still needs to save. Let's denote the amount John needs to save as N(t) at time t, and his savings amount as S(t) at time t. Initially, John needs to save $24,000, so we have N(0) = $24,000.

We know that John has saved $1,000 after the first month, which means S(1) = $1,000. Since his savings amount is proportional to the amount he still needs to save, we can write the proportionality as:

S(t) = k * N(t)

where k is a constant of proportionality.

We need to find the value of k to determine John's savings amount at any given time.

Using the initial values, we can substitute t = 0 and t = 1 into the equation above:

S(0) = k * N(0)  =>  $1,000 = k * $24,000  =>  k = 1/24

Now we have the value of k, and we can write John's savings amount as a function of time:

S(t) = (1/24) * N(t)

Since John's savings amount is proportional to the amount he still needs to save, we can express the amount he still needs to save at time t as:

N(t) = $24,000 - S(t)

Substituting the expression for N(t) into the equation for S(t), we get:

S(t) = (1/24) * ($24,000 - S(t))

Simplifying the equation, we have:

24S(t) = $24,000 - S(t)

25S(t) = $24,000

S(t) = $24,000 / 25

Therefore, John's savings amount at any given time t is S(t) = $24,000 / 25.

Answer:

Step-by-step explanation:

The exponential decay function is

\(v(t)=a(b)^t\) where b, the rate of decay, for us is (1 - .115) and a is the original value of the car which, for us, is 18000. t is the time in years. Using this information to write the equation we need to solve for the value when the car is 10 years old:

\(v(t)=18000(.885)^t\) and we sub in 10 for t:

\(v(t)=18000(.885)^{10\) which simplifies to

v(t) = 18000(.2947356754) so

v(t) = 5305.24

Is there supposed to be a picture or something? I don't see anything.

The total surface area of the cuboid is  1,300cm²

For a cuboid of length L, breadth B, and height H, the total surface area is:

SA = 2*(L*B + L*H + H*B)

Here we know that:

L = 20cm

B = 15cm

H = 10cm

Replacing that in the surface area formula we will get:

SA = 2*(20cm*15cm + 20cm*10cm + 15cm*10cm)

SA = 1,300cm²

That is the total surface area of the cuboid.

A. (–10, –10)

B. (–9, –6)

C. (–5, 1)

D. (1, 12)

E. (4, 7)

Answer:

\(B.\ (-9, -6)\)

\(C.\ (-5, 1)\)

\(D.\ (1, 12)\)

Step-by-step explanation:

A relation is represented as:

\(R->\{(x_1,y_1),(x_2,y_2),(x_3,y_3)...(x_n,y_n)\}\)

Where

\(x = domain\)

\(y = range\)

For a relation to be a function, the domain must be unique and must not be repeated.

In the given function,

\(\{(-9, 1), (-5, 2), (0, 7), (1, 3), (6, -10)\}\)

The domains are \(\{-9,-5,0,1,6\}\)

So, if (6,-10) is to be replaced;

The domain of the ordered pair that will replace it must not be any of \(\{-9,-5,0,1,6\}\)

From the list of given options:

\(B.\ (-9, -6)\)

\(C.\ (-5, 1)\)

\(D.\ (1, 12)\)

The above can not replace (6,-10) because their domain exist already.

The compound interest after 5 years is $7,081.916.

Compound interest:

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

Here we have to find the interest earned after 5 years.

Data given:

Principle (P) = $11600

rate(r) = 10%

time(t) = 5 years.

Formula to find compound interest:

CI = P( 1 + r/100\()^{t}\) - P

Now put the values in the formula.

CI = 11600 ( 1 + 10/100\()^{5}\) - 11600

  = 18681.916 - 11600

  = 7081.916

The blue and green lines are straight lines, so they are linear. The red line is curved, so that is nonlinear.

I plotted out the data from each table on a graph. Tables 1 and 3 both curve when the points are connected, and table 2’s points form a straight line when connected. I am sure there is a mathematical formula to use on these tables, so the drawing wouldn’t have been required. But I knew this would at least get the answers.

Answer:25

Step-by-step explanation:

Removing the electric car from the data set will reduce the standard deviation as the extreme value of 112 mpg is taken out, resulting in a decrease in the spread of the data. The interquartile range (IQR) will also be affected as the extreme outlier is taken out, will decrease the spread of the data in the boxplot.

The electric car with a rating equivalent to 112 miles per gallon is an extreme outlier, which means it is very far from the rest of the data. Therefore, removing this outlier from the data set will decrease the variability and, consequently, decrease the standard deviation. The extreme outlier with the rating equivalent to 112 miles per gallon is outside of the whiskers of the boxplot, which means it is beyond the range of the middle 50% of the data. Therefore, removing this outlier from the data set will decrease the spread of the data in the boxplot and, consequently, decrease the IQR.

The area of the Rectangle, in terms of the variable x, is given by the expression x^2.

To express the area of a rectangle in terms of the variable x, we first need to understand the properties of a rectangle. A rectangle is a quadrilateral with four right angles, where opposite sides are congruent. The formula for the area of a rectangle is given by multiplying the length and width of the rectangle.

Let's assume the length of the rectangle is L and the width is W. Since a rectangle has opposite sides that are congruent, we can express these sides in terms of x as follows:

Length: L = x

Width: W = x

Now, we can calculate the area A of the rectangle using the formula A = L × W:

A = x × x

A = x^2

Therefore, the area of the rectangle, in terms of the variable x, is given by the expression x^2.

this expression holds true for any rectangle where the length and width are equal to x. If you are referring to a specific rectangle or situation.
