Answer: (23.53, 25.47)
Step-by-step explanation:
The confidence interval for population mean(when population standard deviation is unknown) is given by :-
, where 
= sample mean
n = sample size.
s = sample standard deviation.
t* = Critical value.
Given : 
s= 4.4
Confidence level = 90% =0.090
Significance level = 
Sample size : n= 58
Degree of freedom : df= n-1= 57
Using t-distribution table , the critical value :
Then, the confidence interval will be :-
Hence, a 90% confidence interval for the population mean = (23.53, 25.47)
(4,-2) (6,-2) (4,1) are co ordinates for the triangle after the movement
So,
The chart tells us that the people that registered for soccer is 45.
The chart also tells us that the people that registered for basketball is 35.
45 - 35 = 10
10 more people registered for soccer than for basketball.

Final Answer: 8
Answer:
Cholula
Step-by-step explanation:
first find the vlumes of the different pyramids:
FORMULA:
volume = (1/3) * basearea
Cholula- 157,583,664
Cheops- 91,204,000
