Yes 3 yards in 108 inches
Answer:
9miles
Step-by-step explanation:
Answer:
A sample size of at least 737 specimens is required.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the width M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So:
A sample size of at least 737 specimens is required.
Answer: The larger cylinder would 90cm^3
Step-by-step explanation:
If both have a base area of 10cm^3
Try to work the problem normally and just add the cube as your unit. 6cm is your height for the small cylinder so add 3 meaning the large will be 9cm tall. Then multiply, 10cm by 9cm = 90cm^3.
The formal is V=pi r^2 h
Hopefully this helps.
Answer:
12 and 9
Step-by-step explanation:
x=larger number y=smaller number
x+y=21
x=2y-6 (system of equations)
x=21-y
2y-6=21-y
3y=27
y=9
x+9=21
x=12
