Answer:
The 97% confidence interval would be from 108 to 165.
Step-by-step explanation:
Since the 78% confidence interval is from 87 to 133, to determine what the 97% confidence interval would be, the following calculations must be performed:
78 = 87
97 = X
97 x 87/78 = X
8.439 / 78 = X
108.19 = X
78 = 133
97 = X
97 x 133/78 = X
12.901 / 78 = X
165.39 = X
Thus, the 97% confidence interval would be from 108 to 165.
Answer:
706.5 cm^2
Step-by-step explanation:
First we need to find the r to find the area of the base which is the circle so we use the volume to find r
V = 1/3πr^2h now adjust the equation for r
r = √3V/πh
r = √3(4710)/20π
r= 15
now that we have r, the base of cone is a circle so we use the area formula for circle
area = πr²
area = 3.14 (15)^2
area of base = 706.5 cm^2
F=5x
f-1x=5x-1x=4x
so f-1x=4x
