6*8= 48
Git rid of one "48" and replace it with "6" and the empty blank you would enter "8"

Answer:
x=11.25
Step-by-step explanation:
Given that the measures of each exterior angle in a regular hexagon is (4x + 15)°.
Hexagon means there are 6 sides.
We know that sum of all exterior angles of a regular polygon is always 360 degree.
So if there are n sides of polygon then we can write formula:
nA=360
where n= number of sides = 6
A=(4x + 15)° {given each interior angle is equal to (4x + 15)°}
plug these into above formula:
6(4x + 15)°=360°
4x + 15=60
4x = 45
4x = 45
x=11.25
<u>Hence final answer is x=11.25.</u>
Answer:
1245
Step-by-step explanation:
-Given the standard deviation is $9000 and the margin of error is $500.
-the minimum sample size at a 95% confidence level can be calculated using the formula:
![n\geq( \frac{z\sigma}{MOE})^2\\\\\\\geq (\frac{1.96\times 9000}{500})^2\\\\\\\geq 1244.6784\approx 1245](https://tex.z-dn.net/?f=n%5Cgeq%28%20%5Cfrac%7Bz%5Csigma%7D%7BMOE%7D%29%5E2%5C%5C%5C%5C%5C%5C%5Cgeq%20%28%5Cfrac%7B1.96%5Ctimes%209000%7D%7B500%7D%29%5E2%5C%5C%5C%5C%5C%5C%5Cgeq%201244.6784%5Capprox%201245)
Hence, the minimum sample size is 1245
*Since there's no data fromw which we are drawing our variables, we can manually input our parameters in excel and calculate as attached.
