Answer:
Width: 6 cm
Length: 9 cm
Step-by-step explanation:
Width: x
Length: x + 3
2(x)+2(x+3) = 30cm
2x + 2x + 6 = 30
4x = 30-6
x = 24/4
x = 6
Answer:
x=16/3
x=5 1/3
x=5,3333333.....
Step-by-step explanation:
x+2/3= 6
x= 6-2/3
x=16/3
x= 5 1/3
x=5,33333333333......

a solid object where the radius of base is 7 cm and height is 12cm.find the volume of the cylinder.
Answer:
We need to contact 542 employees.
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:
98% confidence level
So , z is the value of Z that has a pvalue of , so .
a) How many randomly selected employers must we contact in order to create an estimate in which we are 98% confident with a margin of error of 5%
We dont know the proportion, so we use , which is when we are going to need the largest sample size.
We have to find n when M = 0.05. So
Rounding up
We need to contact 542 employees.
