Put me as brainliest ive tried i cant figure it out plzz
Answer:
Step-by-step explanation:
Remark
The surface area is the area of all six sides when the object is a box.
Formula
SA = 2*L*w + 2*L*h + 2*w*h
Givens
L = 6 ft
w= 3 ft
h = 2.5 feet
Substitute and Solution
SA = 2*6*3 + 2*6*2.5 + 2*3*2.5
SA = 36 + 30 + 15
SA = 81
Okay so 1 ton is equal to 2,000 pounds... So first you times 1500 by 3 to get 4500. Since 1 ton equals 2,000 you can fit 2 full tons and there's half left over. So your answer is 2 1/2 tons! hope that helps!! :)
What do you mean? Question not clear.
Answer:
A sample of 601 bricks will be needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
How large a sample will we need?
A sample of n bricks will be needed.
n is found when M = 0.04.
We have no estimate for the proportion of defective bricks, so we work with the worst case scenario, which is
Rounding up
A sample of 601 bricks will be needed.
