C : 20
good luck, hope this helped!
8.04 * 100= 804
You move the decimal point two times to the right
8.04*101=812.04
To convert 3/4 to a percent we need to convert 3/4 to a decimal and then multiply the decimal by 100. Lets do it:-
To convert a fraction to a decimal we have to divide the numerator by the denominator.
3/4
3 ÷ 4 = 0.75
Decimal = 0.75
0.75 × 100 = 75
75%.
So, 3/4 in percent form is 75%.
Hope I helped ya!! xD
They are both behind the decimal, they are both a decimal, they can both be turned into a fraction, and they both have a six
Answer:
a.) 60
Step-by-step explanation:
Margin of Error formula = z × s/√n
z = z score of confidence interval
We are given z score of 99% = 2.58
s = Standard deviation = $36
Margin of Error= ± 12
n= unknown
= 12 = 2.58 × 36/√n
12 × √n = 92.88
√n = 92.88/12
√n = 7.74
Square both sides
(√n)² = 7.74²
n = 59.9076
Approximately n ≈ 60
Therefore, the required sample size = 60
