Answer:

Riley is correct

Step-by-step explanation:

Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca.

To find out the fraction of how much more Riley ate than Luca, we carry out Subtraction operation

= Fraction of what Riley ate - Fraction of what Luca ate

= 5/6 - 3/6

Lowe's Common Denominator = 6

= 5 - 3/6

= 2/6

Therefore, Riley is correct

The left side of the equation is equal to the right side, which confirms that a = 11/10 is the correct solution.

To solve the equation, we need to isolate the variable "a". The equation is given as a - 1/2 = 3/5.
To eliminate the fraction, we can multiply both sides of the equation by the least common denominator (LCD), which is 10. This will clear the fractions and make the equation easier to solve.
Multiplying the left side of the equation by 10, we get:
10(a - 1/2) = 10(3/5)
10a - 5 = 6
Next, we can simplify the equation by adding 5 to both sides:
10a - 5 + 5 = 6 + 5
10a = 11
Finally, we can solve for "a" by dividing both sides of the equation by 10:
(10a)/10 = 11/10
a = 11/10
Therefore, the solution to the equation is a = 11/10 or a = 1 1/10.
To check the solution, substitute a = 11/10 back into the original equation:
11/10 - 1/2 = 3/5
(11/10) - (5/10) = 3/5
6/10 = 3/5
In summary, the solution to the equation a - 1/2 = 3/5 is a = 11/10 or a = 1 1/10. This solution has been checked and is correct.

(a) 95% confidence interval for the difference between female and male times is (11.954, 255.591).

(b) The assumptions and conditions for the two-sample t-test are met, so we can use the results of the test and confidence interval.

a) To construct a 95% confidence interval for the difference between female and male times, we can use a two-sample t-test. Let's denote the mean time for female swimmers as μf and the mean time for male swimmers as μm. We want to test the null hypothesis that there is no difference between the two means (i.e., μf - μm = 0) against the alternative hypothesis that there is a difference (i.e., μf - μm ≠ 0).

The formula for the two-sample t-test is:

t = (Xf - Xm - 0) / [sqrt((s^2f / nf) + (s^2m / nm))]

where Xf and Xm are the sample means for female and male swimmers, sf and sm are the sample standard deviations for female and male swimmers, and nf and nm are the sample sizes for female and male swimmers, respectively.

Using the data from the plots, we get:

Xf = 917.5, sf = 348.0137, nf = 15

Xm = 783.7273, sm = 276.0625, nm = 28

Plugging in these values, we get:

t = (917.5 - 783.7273 - 0) / [sqrt((348.0137^2 / 15) + (276.0625^2 / 28))] = 2.4895

Using a t-distribution with (15+28-2) = 41 degrees of freedom and a 95% confidence level, we can look up the critical t-value from a t-table or use a calculator. The critical t-value is approximately 2.021.

The confidence interval for the difference between female and male times is:

(917.5 - 783.7273) ± (2.021)(sqrt((348.0137^2 / 15) + (276.0625^2 / 28)))

= 133.7727 ± 121.8187

= (11.954, 255.591)

Therefore, we can be 95% confident that the true difference between female and male times is between 11.954 and 255.591 minutes.

b) Assumptions and conditions for the two-sample t-test:

Independence, We assume that the observations for each group are independent of each other.

Normality, We assume that the populations from which the samples were drawn are approximately normally distributed. Since the sample sizes are relatively large (15 and 28), we can rely on the central limit theorem to assume normality.

Equal variances, We assume that the population variances for the female and male swimmers are equal. We can test this assumption using the F-test for equality of variances. The test statistic is,

F = s^2f / s^2m

where s^2f and s^2m are the sample variances for female and male swimmers, respectively. If the p-value for the F-test is less than 0.05, we reject the null hypothesis of equal variances. If not, we can assume equal variances. In this case, the F-test yields a p-value of 0.402, so we can assume equal variances.

Sample size, The sample sizes are both greater than 30, so we can assume that the t-distribution is approximately normal.

Option C graph best approximates Jerry's text message plan.

Given,

On Jerry's text message phone plan, she paid $0.30 for every 20 messages she sent.

We need to find what is the cost per message in dollars.

We divide the total cost by the number of items.

Example: 10 pieces cost $20

1 pieces cost = $20/10 = $2

We have,

If A is an n x n matrix with an eigenvalue of λ with multiplicity n, we want to prove that A is diagonalizable if and only if A = λI, where I is the n x n identity matrix.

To show the forward implication, assume A is diagonalizable. Since A has an eigenvalue of λ with multiplicity n, its characteristic polynomial can be written as (λ - λ)^n = 0.

This implies that A has only one eigenvalue, which is λ, and all other eigenvalues must be zero. Since A is diagonalizable, it can be written as A = PDP^(-1), where D is a diagonal matrix containing the eigenvalues of A.

As A has only one eigenvalue, D will have a single entry λ on its diagonal. Therefore, A = λI, where I is the n x n identity matrix.

For the reverse implication, assume A = λI. In this case, the characteristic polynomial of A is (λ - λ)^n = 0, indicating that λ is the only eigenvalue of A with multiplicity n. Moreover, A can be easily diagonalized since it is already in diagonal form.

In summary, if A is an n x n matrix with an eigenvalue of λ with multiplicity n, A is diagonalizable if and only if A = λI, where I is the n x n identity matrix.

Answer:

1360.7 feet^3

Step-by-step explanation:

radius = diameter / 2 = 9 /2 = 4.5 feet

Volume = radius^2 x pi x height = 4.5^2 x 3.14 x 10.7 = 680.3595 feet^3

the water tanks are two so

total volume = 680.3595 x 2 = 1360.719 feet^3

for round the answer to the nearest tenth, we have to look at the number after 7. If it is smaller than 5 we can leave 7, if it its higher or equal to 5, we have to change 7 in 8. In this case is 1, so it remains 7

Final answer = 1360.7 feet^3

The correct value is 720 ft of fencing.

Answer:

Max Area = 64800 sq.ft

Step-by-step explanation:

A square will always give us the maximum area.

Thus, one side would be;

720/4 = 180 feet

So, we want a square 180 ft by 180 ft

however, from the question, we are to use the creek as one side. So, we'll take the 180 ft that we don't need because of the creek and then add it to the opposite side to get 180 + 180 = 360 ft.

Thus,we now have a rectangle with dimensions: 180 ft by 360 ft

Area is given by;

area = length × width

Maximum Area = 180 × 360

Max Area = 64800 sq.ft

Answer:

y=2x-24

Step-by-step explanation:

y--8=2(x-8)

y+8=2x-16

y=2x-24

After answering the presented question, we can conclude that Therefore, the cubic function in standard form that has x-intercepts at (-1,0) (2,0) (4,0) and a y-intercept at (0,-24) is \(f(x) = 3x^3 - 21x^2\) \(+ 14x + 24.\)

In mathematics, a function appears to be a link between two sets of numbers in which each member of the first set (known as the domain) corresponds to a specific member of the second set (called the range). In other words, a function takes input from one collection and creates output from another. The variable x has frequently been used to represent inputs, whereas the variable y has been used to represent outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 depicts a functional form in which each value of x generates a unique value of y.

To find a cubic function in standard form, we can start by using the intercept form of the cubic equation:

\(f(x) = a(x-x1)(x-x2)(x-x3)\\f(x) = a(x+1)(x-2)(x-4)\\-24 = a(0+1)(0-2)(0-4)\\-24 = a(-8)\\a = 3\\\)

So the cubic function in standard form that satisfies the given conditions is:

\(f(x) = 3(x+1)(x-2)(x-4)\\f(x) = 3x^3 - 21x^2 + 14x + 24\\\)

Therefore, the cubic function in standard form that has x-intercepts at (-1,0) (2,0) (4,0) and a y-intercept at (0,-24) is \(f(x) = 3x^3 - 21x^2\) \(+ 14x + 24.\)

The law of conservation of mass states that for a given isolated system, mass (or matter) can not be created neither can it be destroyed, but it can be transformed into different forms

Therefore, whereby all the wood Chuck chops is taken as firewood, (wood which is dry is about 100% consumable as firewood) the mass of the wool before he chopped the wood = The mass of the firewood he had after chopping the wood = 25 kg

Weight = Mass × The acceleration due to gravity, g

Step-by-step explanation:

The number of nonnegative integer solutions to the inequality x1 + x2 + x3 ≤ 11 is C(14,3) = 364.

We can solve this inequality by introducing an auxiliary variable x4, such that x1 + x2 + x3 + x4 = 11. Here, x1, x2, x3, and x4 are all nonnegative integers.

We can interpret this equation as follows: imagine we have 11 identical objects and we want to distribute them among four boxes (x1, x2, x3, and x4). Each box can contain any number of objects, including zero. The number of solutions to this equation will give us the number of nonnegative integer solutions to the original inequality.

We can use a technique known as stars and bars to count the number of solutions to this equation. Imagine we represent the 11 objects as stars: ***********.

We can then place three bars to divide the stars into four groups, each group representing one of the variables x1, x2, x3, and x4. For example, if we place the first bar after the first star, the second bar after the third star, and the third bar after the fifth star, we get the following arrangement:

| ** | * | ****

This arrangement corresponds to the solution x1=1, x2=2, x3=1, and x4=7. Notice that the number of stars to the left of the first bar gives the value of x1, the number of stars between the first and second bars gives the value of x2, and so on.

We can place the bars in any order, so we need to count the number of ways to arrange three bars among 14 positions (11 stars and 3 bars). This is equivalent to choosing 3 positions out of 14 to place the bars, which can be done in C(14,3) ways.

Therefore, the number of nonnegative integer solutions to the inequality x1 + x2 + x3 ≤ 11 is C(14,3) = 364.
