Answer:
Confidence interval
And the margin of error would be:
Step-by-step explanation:
For this case we have the followig dataset:
DATA: 8.2; 9.1; 7.7; 8.6; 6.9; 11.2; 10.1; 9.9; 8.9; 9.2; 7.5; 10.5
We can calculate the mean and the deviation with the following formulas:
And replacing we got:
![\bar X= 8.98[/tex[tex]s = 1.29](https://tex.z-dn.net/?f=%20%5Cbar%20X%3D%208.98%5B%2Ftex%3C%2Fp%3E%3Cp%3E%5Btex%5Ds%20%3D%201.29)
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.95 or 95%, the value of significance is 
and 
, and the critical value would be 
Repplacing the info we got:
And the margin of error would be:

Answer:
tbh there are quite a lot of possibilities
I'll just name the properties but not show which angle applies to it cos that's too time consuming
Step-by-step explanation:
vertically opposite angles
interior / exterior alternate angles
corresponding angles
angles on a straight line are supplementary

Answer:
7%
Step-by-step explanation:
Using the formula
Amount = Principal + Interest
Give the following
Principal = ₹ 5000
Amount =₹ 6050
Time = 3 years
Required
Time
Substitute into the formula
A = P + I
A = P + PRT/100
6050 = 5000 + 5000(R)(3)/100
6050 - 5000 = 150R
1050 = 150R
R = 1050/150
R = 7
Hence the rate of interest is 7%
