(A) f(a + 2) = a² - 16

substitute x = a + 2 into f(x)

f(a + 2) = (a + 2)² - 4(a + 2) - 12

           = a² + 4a + 4 - 4a - 8 - 12

           = a² - 16

(B ) f(a + h) = a² + 2ah + h² - 4a - 4h - 12

substitute x = a + h into f(x)

f(a + h) = a² + 2ah + h² - 4a - 4h - 12

Specifications call for the wall thickness of two-liter polycarbonate bottles to average 4.0 mils. A quality control engineer sa
bija089 [108]

Answer:

The null hypothesis μ=4.0 could not be rejected.

Step-by-step explanation:

In this problem we have to perform a hypothesis test of the mean, with s.d. of the population unknown.

The sample is: [3.999, 4.037, 4.116, 4.063, 3.969, 3.955, 4.091]

This sample has a mean of 4.033 and a standard deviation of 0.061.

The null and alternative hypothesis are:

H_0: \mu = 4.0\\\\H_1: \mu \neq 4.0

We assume a significance level of 0.05.

The test statistic for this test is:

t=\frac{M-\mu}{\sigma}=\frac{4.033-4.0}{0.061}=0.536

We have a sample size n=7, so the degrees of freedom are 7-1=6.

For a two-tailed test, t=0.536 and df=6, the P-value can be look up in a t-table.

The P-value is 0.61. Is greater than the significance level, so the effect is not significant and the null hypothesis can't be rejected.

The height of Tower A is 720 feet more than Tower B. The two towers have a combined height of 1,982 feet. What are the heights o
Kobotan [32]
Okay so. 

We have two basic equations 

Tower A+ B+720    A is 720ft taller than B. 
Tower A+B= 1982     Combined height is 1982ft

Replace A with B+720 in 2nd equation and solve for B 

B+720+B=1982   Combine like terms 
2B+720=1982     Subtract 720 from both sides
2B=1262              Divide both sides by 2
B=1262/2 
B= 631ft 

We know that A=B+720 so you simply need to do that addition to have the height of both towers.
