Answer:
24/7
Step-by-step explanation:
cos(theta)=24/25
so draw right triangle
you get the length of each side be
7 24 25
(you must draw a picture)
then the answer would be 24/7
Answer:
The answer to this question is within 2 stabdard deviations
Step-by-step explanation:
to get the score of 85 you got to add the deviation value to the mean whuch creates the deviation. do that multiple times and you get a multiple deviation
72+8=80+8 is 88
88 is greater than 85 so a test score of 85 is within 2 standard deviations of the mean
The A/= it means the answer is okay.
Answer: 4 or 
To find the square root of a number, remember that there will be two factors that are the same that will give you the product.
Lets start from 1:
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.
4 and 4 are the same numbers.
Therefore, 
= 4
