Answer:
So the answer for this case would be n=183 rounded up to the nearest integer
Step-by-step explanation:
Information provided
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
the margin of error desired
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =0.023 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence level is 97% or 0.97 and the significance would be
and
then the critical value would be:
, replacing into formula (5) we got:
So the answer for this case would be n=183 rounded up to the nearest integer
In total it has to be 180 since a straight line is 180 so i would be 69
Answer:
42 square units
Step-by-step explanation:
The base is 6 and the is 7
Area of rectangle= Base × Length
=6×7
=42 square units
Let's take radius of the basket ball as b
l<span>et's take radius of the tennis ball as t
b = 3.6 t
</span>volume of the basket <span>ball vb = 4/3 pi b^3
</span>volume of the tennis <span>ball vt = 4/3 pi t^3
</span>
therefore
vb / vt = b^3 / t^3
= (3.6t)^3 / <span>t^3
= 3.6^3
= 46.656
so the volume of the basketball is 46.656 times greater than the volume of the tennis ball.</span>
