Answer:
<em>It's </em><em>B</em><em>, the diagonals bisect each other</em>
Step-by-step explanation:
If they were equal, it would have to be a rectangle. If they were perpendicular, it would have to be a sqaure.
Answer:
Option (b) is correct.
The profit from sales if the price of the T-shirts were $15 a pieces is $28.
Step-by-step explanation:
Given : The function
is used to determine the profit on T-shirts sold for x dollars.
We have to find the profit from sales if the price of the T-shirts were $15 a pieces.
Consider the given profit function 
For the profit, if the price of a t-shirt is $ 15
Put x = 15, we have,

Simplify, we have,

Also, 
Thus, we get, The profit from sales if the price of the T-shirts were $15 a pieces is $28.

Answer:
11.7
Step-by-step explanation:
pythagorean theorem is 
apply that same formula soo 
then sqaure root 136
round that soo now the answer is 11.7
To solve this, we use the z test.
The formula:
z = (x – u) / s
where x is sample value = 20, u is the mean = 15, and s is
the standard deviation = 2.5
z = (20 – 15) / 2.5
z = 2
Since we are looking for values greater than 20, this is
right tailed test. We use the standard distribution tables to find for P.
P = 0.0228
Therefore:
number of students = 100 * 0.0228 = 2.28
<span>2 to 3 students will get greater than 20 measurement</span>
