Question:

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.​​​​​​

A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.

Answer:

\(y = 97522.7\)

Step-by-step explanation:

Given

\(y = 1.5x + 22.7\)

\(x = 65000\)

Required

Find y

Substitute 65000 for x in the given equation

\(y = 1.5 * 65000 + 22.7\)

\(y = 97500 + 22.7\)

\(y = 97522.7\)

It is reasonable because as the population increases, the noise level also increases

The slope of the line that passes through the points (-1,4) and (0,9) is 5.

Slope is simply expressed as change in y over the change in x.

The formula for slope of a line is:

\(m = \frac{ y_2 - y_1}{x_2 - x_1}\)

Given that, the line passes through the points: (-1,4) and (0,9).

Point 1 (-1,4)

Point 2 (0,9)

Plug the given x and y values into the slope formula and simplify.

\(m = \frac{ y_2 - y_1}{x_2 - x_1}\\\\m = \frac{ 9 - 4}{0 - (-1)}\\\\m = \frac{ 5}{0 + 1}\\\\m = 5\)

Therefore, the slope of the line is 5.

Answer:

the healer gave Harold a deferred payment plan. The expression for the amount of Harold’s last payment is x - 100y

Step-by-step explanation:

The dealer gave Harold an installment plan with a down payment. The expression for the amount of Harold’s last payment is x-100y.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

An installment plan is a type of payment plan in which the purchase price is paid in a series of payments, rather than all at once. A down payment is an initial payment made when purchasing a costly item, such as a car or house, with the intention of paying the remaining balance in a series of payments.

The expression for the amount of Harold's last payment is x - 100y. This is because the monthly payments are 100 dollars and there are y months of payments, so the total amount of payments made is 100y. The remaining balance is the original purchase price minus the total amount of payments made, which is x - 100y.

Answer:

This is an arithmetic sequence because there is a common difference of 4 between each term

The length of the hypotenuse is 7m.

Let the side opposite to 30° be the shortest leg.

The side opposite to 60° is the longest leg.

So, the side opposite to 90° is hypotenuse.

Length of the shortest side is x.

Length of longest side is \(\sqrt{3}x\)

Length of the hypotenuse is 2x.

We know x = 7

So, \(\sqrt{3}(x)=\sqrt{3}(7)\)

Thus, the length of the longer leg is \(\sqrt{3}(7)\) m

Length of hypotenuse = 2x = 2(7) = 14m

\(x^{2} +(\sqrt{3} x)^2 =(2x)^2\\\\(7)^2+(\sqrt{3} (7))^2=(2x)^2\\\\49 + (3(49)) = (2x)^2\\\\49 + 147= (2x)^2\\\\(2x)^2=196\)

Taking square root on both sides:

\(2x = \sqrt{196}\)

2x = 14

x = 7

Therefore, the length of the hypotenuse is 7m.

Using the z-distribution, it is found that the p-value for this test is of 0.0375.

At the null hypothesis, it is tested if the expenses are the same as the national average, that is, of $5,423. Hence:

\(H_0: \mu = 5423\)

At the alternative hypothesis, it is tested if it is higher, hence:

\(H_1: \mu > 5423\)

We have the standard deviation for the population, thus, the z-distribution is used. The test statistic is given by:

\(z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}\)

The parameters are:

For this problem, the values of the parameters are: \(\overline{x} = 5516, \mu = 5423, \sigma = 979, n = 352\)

The value of the test statistic is:

\(z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}\)

\(z = \frac{5516 - 5423}{\frac{979}{\sqrt{352}}}\)

\(z = 1.78\)

The p-value is the probability of finding a sample mean above $5,516, which is 1 subtracted by the p-value of z = 1.78.

1 - 0.9625 = 0.0375

Hence, the p-value for this test is of 0.0375.

Answer: y = 5x-2

Step-by-step explanation:

Answer:

k > 1, or k ≥ 2

Step-by-step explanation:

aₙ = (n!)² / (kn)!

aₙ₊₁ = ((n+1)!)² / (k(n+1))!

lim(n→∞)│aₙ₊₁ / aₙ│

lim(n→∞)│[((n+1)!)² / (k(n+1))!] / [(n!)² / (kn)!]│

lim(n→∞)│[((n+1)!)² / (k(n+1))!] × [(kn)! / (n!)²]│

lim(n→∞)│[((n+1)!)² / (n!)²] × [(kn)! / (k(n+1))!]│

lim(n→∞)│[((n+1)! / n!)²] × [(kn)! / (kn+k)!]│

lim(n→∞) (n+1)² × (kn)! / (kn+k)!

This converges when the limit is less than 1.

If k=1:

lim(n→∞) (n+1)² × n! / (n+1)! = lim(n→∞) (n+1) = ∞

If k=2:

lim(n→∞) (n+1)² × (2n)! / (2n+2)! = lim(n→∞) (n+1)² / [(2n+2)(2n+1)] = 1/4

If k=3:

lim(n→∞) (n+1)² × (3n)! / (3n+3)! = lim(n→∞) (n+1)² / [(3n+3)(3n+2)(3n+1)] = 0

The series converges for k > 1, or k ≥ 2.

After solving the given equation, the values obtained will be equal to 210° and 330°. Hence, option B is correct.

The solution to the above algebra question is  (b) x-3, x+5.

To find the remaining factors of the polynomial x^3+4x^2-11x-30=0, we can use polynomial long division or synthetic division. However, since we are given that x+2 is a factor of the polynomial, we can use synthetic division to simplify the process.

We set up the synthetic division table as follows, using -2 as the divisor:

-2 | 1 4 -11 -30

|____-2__-4___30

| 1 2 -15 0

The bottom row of the table represents the coefficients of the quadratic polynomial obtained by dividing x^3+4x^2-11x-30 by x+2. The last term of the quadratic is 0, which indicates that x+2 is a factor of the polynomial. The remaining quadratic polynomial can be factored as:

x^2 + 2x - 15 = (x - 3)(x + 5)

Therefore, the remaining factors of the polynomial x^3+4x^2-11x-30=0 are x+2, x-3, and x+5.

The correct answer is (b) x-3, x+5.

The expression 48s represents the number of scarves (s) and its per unit  (48).

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given that, Emiko makes shibori scarves and sells them for $48 each on a website for handmade goods.

Here, the expression 48s represents the total price of buying s scarves

We need to tell what 48s mean,

So,

48s here is the total cost for buying s scarves,

That mean, if we buy s scarves we will have to pay $48s

Similarly, if we will buy 4 scarves, we will pay = 48 × 4 = $192

For 10 scarves, we will pay = 48 × 10 = $480

Therefore, we can say $48 is the unit price of the scarf.

Hence, the expression 48s represents the number of scarves (s) and its per unit  (48).

  $1,021,337.13

Step-by-step explanation:

The sum of present values of medical expenses is ...

  30,000/1.05 +30,000(1.0513)/1.05^2 +30,000(1.0513^2)/1.05^3 +...

So, the series has an initial value of 30,000/1.05 and a common ratio of 1.0513/1.05. Its sum is given by ...

  S = a(r^n -1)/(r -1)

where a = 30,000/1.05, n = 35, r = 1.0513/1.05.

Filling in these values and doing the arithmetic, we get ...

  S = $1,021,337.13

You need an initial deposit of $1,021,337.13 to cover rising expenses for 35 years.
