Angleslice/360 times area=area of slice
area=pir^2
normally pizzas are given in terms of ther diameter
so 10=diameter
d/2=r, 10/2=5
r=5
area=pi5^2=25pi
angleslize/360 times 25pi=15
do math
times 360 both sides and divide by 25pi both sides
angle=68.7549 degrees or 1.2 radians
Answer: The point estimate of the population mean is <u>23</u>. The margin of error for the confidence interval is <u>2</u>.
Step-by-step explanation:
The confidence interval for the mean is of the form is given by :-
Given : Lower bound: 
Upper bound :
Then ,the sum of lower and upper bound will be :-
Since
Hence, The point estimate of the population mean is <u>23</u>. The margin of error for the confidence interval is <u>2</u>.

The formula for simple interest is i = p*r*t, where r is the annual interest rate expressed as a decimal fraction.
Here, $16 = $200*r*2, with r being the unknown.
Solving for r: r = $16 / $400 = 0.04 (answer)
