Answer:

D. +3.82

Step-by-step explanation:

The computation of the test static for this test is shown below:

Data provided in the question

$\bar x$ = $8,745

$\mu$ = $8,500

$\sigma$ = $1,200 and n = 350

Now based on the above information, the test static for this test is

$z = \frac{\bar x - \mu}{\frac{\sigma}{\sqrt{n} } }$

$z = \frac{\$8,745 - \$8,500}{\frac{\$1,200}{\sqrt{350} } } \\$

= 3.82

= +3.82

Hence, the test static for this test is +3.82

We simply applied the above formula so that the correct value could come

And, the same is to be considered

The area of a rectangle is 27 ft2 , and the length of the rectangle is 3 ft less than double the width. find the dimensions of t

user100 [1]

Let w be the width;and 2w-3 be the length. Then:
w(2w-3)=27
2w²-3w-27=0
(2w-9)(w+3)=0
w=9/2 or -3
The width is 9/2 ft, the length is 6
