Answer:
A rectangular prism in which BA = 20 and h = 6 has a volume of 120 units3; therefore, Shannon is correct
Step-by-step explanation:
step 1
Find the area of the base of the rectangular pyramid
we know that
The volume of the rectangular pyramid is equal to
where
B is the area of the base
H is the height of the pyramid
we have
substitute and solve for B
step 2
Find the volume of the rectangular prism with the same base area and height
we know that
The volume of the rectangular prism is equal to
we have
substitute
therefore
The rectangular prism has a volume that is three times the size of the given rectangular pyramid. Shannon is correct
Part a)
The simple random sample of size n=36 is obtained from a population with
and
The sampling distribution of the sample means has a mean that is equal to mean of the population the sample has been drawn from.
Therefore the sampling distribution has a mean of
The standard error of the means becomes the standard deviation of the sampling distribution.
Part b) We want to find
We need to convert to z-score.
Part c)
We want to find
We convert to z-score and use the normal distribution table to find the corresponding area.
Part d)
We want to find :
We convert to z-scores and again use the standard normal distribution table.

<h3><em>the </em><em>answer</em><em> </em><em>is </em><em>A</em></h3>
Step-by-step explanation:
8x+6is equivalent to-7(1-x)+x+13 because
-7(1-x)+x+13
we use-7to multiply the numbers in the bracket which is equal to -7+7x(minus ❌times minus =+)
-7+7x+x+13
collect like terms
7x+x+13-7=8x+6
answer is A
Answer:
m < 16
Step-by-step explanation:
598 + 15.75m < 850
15.75m < 850 - 598
15.75m < 252
m < 16
Answer:
40%
Step-by-step explanation:
Netflix:
22% - 10% = 12%
HBO:
38% - 10% = 28%
People who watch Netflix only: 12%
People who watch HBO only: 28%
People who watch both Netflix & HBO: 10%
People who watch HBO or Netflix: 12% + 28% + 10% = 40%
