Answer:
(a) 93.19%
(b) 267.3
Step-by-step explanation:
The population mean and standard deviation are given as 502 and 116 respectively.
Consider, <em>X</em> be the random variable that shows the SAT critical reading score is normally distributed.
(a) The percent of the SAT verbal scores are less than 675 can be calculated as:
Thus, the required percentage is 93.19%
(b)
The number of SAT verbal scores that are expected to be greater than 575 can be calculated as:
So,
Out of 1000 randomly selected SAT verbal scores, 1000(0.2673) = 267.3 are expected to have greater than 575.

Answer:
<em>The volume of pyramid B is 64 times the volume of pyramid A.</em>
<em></em>
Step-by-step explanation:
Given:
Two square pyramids A and B.
Side Length of A, 
12 inches
Height of A, 
8 inches
Side Length of B, 
48 inches
Height of B, 
32 inches
To find:
How many times bigger is the volume of pyramid B than pyramid A?
OR
is how many times bigger than 
?
Solution:
First of all, let us have a look at the formula for volume of a pyramid:
Here, base is square, so:
Volume of pyramid A:
Volume of pyramid B:
<em>The volume of pyramid B is 64 times the volume of pyramid A.</em>
Answer:
The answer is all real numbers
Step-by-step explanation:
4(x + 2) = 4x +8
Distribute the 4:
4x + 8 = 4x + 8
Then subtract 4x and 8 from both sides
0 = 0
This statement is true so its all real numbers
