Answer: E: 15 mi
F: 1.7 in
G: 2/3 ft
A: r=6 in
B: r=1 yd
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
It's easy to find the volume of a cube! The equation is:
l x w x h or Length x Width x Height.
Since a cube's sides are all the same size, we can use 5 for all 3 of these values.
5 x 5 x 5 = 125
So, the volume of this cube is 125!
The chords ar of equallength so
3x - 15 = 2x - 4
x = -4 + 15 = 11
So the chord JK = 3(11) - 15
= 18 answer
Answer: 
Step-by-step explanation:
Given : Sample size : n= 36 , which is a large sample (n>30) so the test applied here is z-test.
Significance level : 
Using Standard normal table , Critical value : 
Sample mean : 
Standard deviation: 
The confidence interval for population means is given by :-

i.e.

Hence, the 95 percent confidence interval for the fill rate =
