Answer: B or 52
Step-by-step explanation: I will explain later
Answer:
A.
Step-by-step explanation:
Answer:
option (c) n = 201
Step-by-step explanation:
Data provided in the question:
Standard deviation, s = 5.5 ounce
Confidence level = 99%
Length of confidence interval = 2 ounces
Therefore,
margin of error, E = (Length of confidence interval ) ÷ 2
= 2 ÷ 2
= 1 ounce
Now,
E = 
here,
z = 2.58 for 99% confidence interval
n = sample size
thus,
1 = 
or
n = (2.58 × 5.5)²
or
n = 201.3561 ≈ 201
Hence,
option (c) n = 201
The answer is 43 because it is half of 86 which is the radius
Answer:
Volume= 27. 12inches³
Step-by-step explanation:
to solve this question lets write out the parameters given
radius of the cylinder = 1.2 inches
height of the cylinder = 6 inches
volume of the cylinder = ?
<u>solution</u>
the fomular to find the volume of a cylinder is given to be
Volume= πr²h
Volume= 3.14 × ( 1.2)² × 6
Volume= 3.14 × 1.44 × 6
Volume= 27. 12inches³
therefore the volume of the cylinder equals to 27. 12inches³
