Step-by-step explanation:

Hey!

I think there might be some confusion on the problem. Here's what I get:

Arranging in ascending order:

$71,\:79,\:83,\:85,\:86,\:88,\:89,\:90,\:93,\:93$

Since there are 10 terms, that is an even number. We will find the two numbers that are middlemost, and then divide them by two.

We see that 86 and 88 are the middlemost. 86 + 88 = 174

174 ÷ 2 = 87.

Thus, the median is $\boxed{87}$ .

Hope this clears up any confusion!

What is the area of the regular hexagon? This is due tomorrow please help! :)

tester [92]

Check the picture below.

so then, the perimeter of that hexagon will just be the sum of all its 6 sides, or namely 3⅖ + 3⅖ + 3⅖ + 3⅖ + 3⅖ + 3⅖, or just 6( 3⅖ ).

$\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} a=apothem\\ p=perimeter\\[-0.5em] \hrulefill\\ a=3\\ p=6\left(3\frac{2}{5} \right) \end{cases}\implies A=\cfrac{1}{2}(3)\left[ 6\left(3\frac{2}{5} \right) \right]\implies A=\cfrac{1}{2}(3)\left[ 6\left(\cfrac{17}{5} \right) \right] \\\\\\ A=\cfrac{1}{2}(3)\left(\cfrac{102}{5} \right)\implies A=\cfrac{1}{2}\left( \cfrac{306}{5} \right)\implies A=\cfrac{153}{5}\implies A=30\frac{3}{5}$

4d + 5 >= 13 or 7d - 2 <12

vivado [14]

I'm guessing that the >= is a greater than or equal to sign, so the answer should be d>=2 and d<2, please tell me if I am wrong and I will do my best to correct it!

In the book Business Research Methods, Donald R. Cooper and C. William Emory (1995) discuss a manager who wishes to compare the

S_A_V [24]

Answer:

Null hypothesis is: U1 - U2 ≤ 0

Alternative hypothesis is U1 - U2 > 0

Step-by-step explanation:

The question involves a comparison of the two types of training given to the salespeople. The requirement is to set up the hypothesis that type A training leads to higher mean weakly sales compared to type B training.

Let U1 = mean sales by type A trainees

Let U2 = mean sales by type B trainees

Therefore, the null hypothesis (H0) is: U1 - U2 ≤ 0

This implies that type A training does not result in higher mean weekly sales than type B training.

The alternative hypothesis (H1) is: U1 - U2 > 0

This implies that type A training indeed results in higher mean weekly sales than type B training.
