Answer: (72.535, 76.665)
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
= population standard deviation.
n= Sample size
= sample mean.
= Critical z-value (two-tailed)
Given : 
n= 81
The critical values for 90% confidence interval : 
Now, the confidence interval for population mean would be :
Hence, a 90 percent confidence interval estimatefor the average score of all students. : (72.535, 76.665)
Answer:
Plot the points (0,0) , (5, 4) and (-5, -4).
Step-by-step explanation:
You could plot three points. Then if they have been plotted correctly the graph will be a straight line joining these 3 points.
The 3 points could be
x y
0 0
5 4 ( 4 because y = 4/5 * 5 = 4)
-5 -4 ( y = 4/5 * -5 = -4).
2x+29=10x-27
29=8x-27
56=8x
x=7
2(7)+29=43
10(7)-27=43
360-43(2)=274
274/2=137
measure of V = 137
Answer: 4.5
Step-by-step explanation:
S= ut + 1/2(at)
S= 10(1/2) + 1/2(-2x1/2)
S= 5 + 1/2(-1)
S= 5 + (-.5)
S= 4.5
