Answer:
30
Step-by-step explanation:
Here, it is given that the Z – score corresponding to the score X = 45 is 1.5 and the Z – score corresponding to the score X = 40 is...
Z = 
So:
1/ 1.5 = 
and 1 = 
. solve the both equations, we found out:
<=> S = 10
=> M = 30
Hence, mean is:
M = 45 -1.5S = 45 - 1.5 (10) = 30
Answer:
a) 1170
b) 35%
c) 630

Answer:
yes
Step-by-step explanation:
14² +48² = 196 +2304 = 2500 = 50²
The three lengths (14, 48, 50) are a Pythagorean triple.

<em>Additional comment</em>
The two smaller numbers correspond to side lengths. The larger one corresponds to the hypotenuse length.
We typically write the numbers of a Pythagorean triple in increasing order, but the order doesn't really matter. As sides of a triangle, the triangle formed is a right triangle, regardless of the order.
Answer:
3/5
Step-by-step explanation:
sin is opposite over hypotenuse
find hypotenuse first -> Hypotenuse = 100 m
(notice that it is a 3-4-5 triangle)
60/100 = 6/10 = 3/5
3×9=27-2=25
3× what # - 2= 25
