Answer:
The new volume will be V + 0.06V or 1.06V
Step-by-step explanation:
The volume of the sphere increased by 6% or 0.06V. This means the total volume of the sphere will be V + 0.06V or 1.06V.
Answer: Area is 20
Step-by-step explanation:
Perimeter of a rectangle is 24
Let the length be x
Let the breadth be Y
Length is 5times the breadth
I.e
X=5y
Formula for perimeter of a rectangle is
2(length + breadth)
= 2(x+y)
Substitute for x=5y
2(5y+y)=24
2(6y)=24
6y=24/2
6y=12
Y=12/6
Y=2
Breadth = 2
Since length =5y
Length=5(2)
Length = 10
Area of a rectangle = length × breadth
Area= 10×2
Area = 20
Area of the rectangle is 20
The answer would be B, due to the fact that the shaded area is above the line.
Answer: (103.74,112.06)
Step-by-step explanation:
The confidence interval for population mean is given by :_
Given : Sample size : n= 50
Sample mean : 
Standard deviation : 
Significance level : 
Critical value : 
Then the 95% confidence interval for the student IQ in the school will be :-
Hence, the 95% confidence interval for the student IQ in the school= (103.74,112.06)
