Answer:
Step-by-step explanation:
radius r = 4 in
slant height L = 15 in
base area = πr² = 16π in²
lateral area = πrL = 60π in²
surface area = 76π in²
r = 4×6, L = 15×6
base area = (4×6)²π = 16π×36
lateral area = 60π×36
surface area is multiplied by 36
Answer:
x = 25 and <A = 148 degrees
Step-by-step explanation:
Basically it's asking you to find the value of x for both of those equations, x must be the same for both
6x - 2 = 4x + 48
2 3/5 or 2 6/10 is the answer
Answer:
And the best option for this case would be:
a. (17.5, 21.7)
Step-by-step explanation:
Information given
represent the sample mean
population mean
represent the population deviation
n=42 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom, given by:
Since the Confidence is 0.98 or 98%, the significance would be
and
, and the critical value would be
Replacing we got:
And the best option for this case would be:
a. (17.5, 21.7)
