Answer:

C) x³ -4x² - 24x + 21.

Step-by-step explanation:

Given : (x – 7)(x² + 3x – 3).

To find : Multiply the polynomials.

Solution : We have given  (x – 7)(x² + 3x – 3).

Distributes x over (x² + 3x – 3) and  -7 over (x² + 3x – 3).

Then

x (x² + 3x – 3) -7(x² + 3x – 3).

x³ + 3x² -3x - 7x² - 21x +21.

Combine like terms

x³ + 3x² - 7x² -3x -21x + 21.

x³ -4x² - 24x + 21.

Therefore, C) x³ -4x² - 24x + 21.

A study was conducted to compare the proportion of drivers in Boston and New York who wore seat belts while driving. Data were c
In-s [12.5K]

(A.)test statistic for this test using Ha: p8くPN is Z = -2.164 (B.) p-value (3 decimal places) is 0.015. (C.) Based on this p-value, which of the following would you expect for a 95% is negative. (D.) the correct conclusion is The proportion of Boston drivers wearing seat was significantly lower than the proportion of new York drivers wearing seat belts.

A.)

According to given data find the test statistic for this test using Ha:

p1 = 0.581

p2 = 0.832

standard error = SE = 0.116

<h3>Test statistics :-</h3>

Z = \frac{p1 - p2}{SE}

Z = \frac{0.581 - 0.832}{0.116} = -2.164

Z = -2.164

B.)

According to given Determine the p-value (3 decimal places).

<h3>p - value</h3>

it is left tailed test.

p - value for left tailed test is,

p - value = P(Z < test statistics )

p - value = P(Z < -2.164)

P - value = 0.015

C.)

Based on this p-value, which of the following would you expect for a 95%

confidence level = 95% = 0.95

significance level = α = 0.05

P -value is less than 0.05

so, reject null hypothesis at α = 0.05

That is P_{B} < P_{NY}

so, based on P - value , All values in the 95% confidence interval

PB - PNY  is negative.

D.)

According to given data What is the correct conclusion?

Reject null hypothesis at α = 0.05

so, P_{B} < P_{NY}

Hence, The proportion of Boston drivers wearing seat was significantly lower than the proportion of new York drivers wearing seat belts.

BlackZzzverrR [31]

The expression 2×2×2×5 shows the prime factorization of 40.

Prime factorization:

The number 40 is equal to

2 x 2 x 2 x 5, or   = 40

23 x 5. = 40

<h3>What does prime factorization serve as?</h3>

In mental arithmetic, fractions, finding square roots, and computing the HCF and LCM of two smaller numbers, prime factorization is a highly helpful tool when working with whole numbers. A whole number higher than 1 whose only elements are 1 and itself is referred to as a prime number. A whole number that may be split evenly into another number is referred to as a factor.
