Answer:

f(2h) = -4h + 9

Step-by-step explanation:

Jacob:  Start with the given function f(x) = -2x + 9 and replace 'x' with 2h:

f(x) = -2x + 9 becomes:

f(2h) = -2(2h) + 9, or

f(2h) = -4h + 9

1/3×(9x + 3) = 3x = - 1 3​
balu736 [363]

Answer:

1/3* (9x-6) = 2x+3

⇒ (1/3)(9x)- (1/3)*6 = 2x+3 (distributive property)

⇒ 3x - 2= 2x + 3

⇒ (3x-2x) -2 = (2x-2x) +3

⇒ x-2=3

⇒ x +(-2+2) = 3+2

⇒ x= 5.

A sample size of n = 64 is drawn from a population whose standard deviation is o = 5.6.
AlekseyPX

Answer:

The margin of error for a 99% confidence interval for the population mean is 1.8025.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.99}{2} = 0.005

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.005 = 0.995, so z = 2.575

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

In this problem:

\sigma = 5.6

So

M = 2.575*\frac{5.6}{\sqrt{64}} = 1.8025

The margin of error for a 99% confidence interval for the population mean is 1.8025.
