Answer:
The surface area is 78 unit square.
Step-by-step explanation:
Given : The surface area for a rectangular prism with a square base is 
.
To find : What is the surface area if s=3 and h=5?
Solution :
The surface area for a rectangular prism with a square base is
Substitute, s=3 and h=5
Therefore, The surface area is 78 unit square.
So we are given the mean and the s.d.. The mean is 100 and the sd is 15 and we are trying the select a random person who has an I.Q. of over 126. So our first step is to use our z-score equation:
z = x - mean/s.d.
where x is our I.Q. we are looking for
So we plug in our numbers and we get:
126-100/15 = 1.73333
Next we look at our z-score table for our P-value and I got 0.9582
Since we are looking for a person who has an I.Q. higher than 126, we do 1 - P. So we get
1 - 0.9582 = 0.0418
Since they are asking for the probability, we multiply our P-value by 100, and we get
0.0418 * 100 = 4.18%
And our answer is
4.18% that a randomly selected person has an I.Q. above 126
Hopes this helps!
Alright, so the slope is alws in the middle so “u”
Answer:
22 inches
Step-by-step explanation:
Width (16) x 2 = 32
72 (perimeter) - 32 (width x 2) = 44 inches
44 divided by 2 is 22, which is the length.
