Answer:
The final step in determining the volume of the pyramid is V = one-third (30) (12).
Step-by-step explanation:
Given : Abdul started solving for the volume of the pyramid using the steps below. V = one-third B h
A rectangular pyramid with a base of 10 meters by 3 meters and a height of 12 meters.
To find : What is the final step in determining the volume of the pyramid?
Solution :
The volume of pyramid is V = one-third B h
The base is B=(3) (10) = 30 meters squared
The height is h=12 meters
Substitute the value,
V = one-third (30) (12)
Therefore, the final step in determining the volume of the pyramid is V = one-third (30) (12).
So, option 1 is correct.
Answer: 3b + 125 = 157.97
Step-by-step explanation:
The two things contributing to the total cost are the cost of the bags of dog food and the adoption fee, so they need to be added together.
There are 3 bags of dog food at an unknown price, so we need to multiply 3 by an unknown value represented by the variable b.
The $125 adoption fee should be added to the price of the bags of dog food, so add 125. This creates an equation of 3b + 125 = 157.97
Answer:
(0.4578 , 0.5318)
Step-by-step explanation:
The attached figure shows the formula for calculating confidence intervals for the difference of proportions in large samples.
Let's call
= proportion of married couples, in the first sample, who had two or more personality preferences in common.
= 197/347 = 0.5677
= size of the first random sample
= proportion of married couples, in the second sample, who had no preferences in common.
= 39/535 = 0.0729
= size of the second random sample = 535
= confidence%.
= 80%
Looking in the normal standard table, we have that = 1.28.
Substituting this values in the formula we have:
Then the confidence interval for p1-p2 is: (0.4578 , 0.5318)
Answer:
C
Step-by-step explanation:
Given the volume = cm³
and the volume of the cube with side x = x³, then
x³ = ← take the cube root of both sides
=
Note that = × ×
Hence
x = → C
