Suppose the correlation coefficient between a predictor variable (a person’s height, measured in centimeters) and a response variable (a person’s weight, measured in kilograms) is 0.72.Suppose that we change the units used to measure height from centimeters to inches and the units used to measure weight from kilograms to pounds, and then we recompute the correlation coefficient. Which of the following would be true?Select one:a. The new correlation coefficient should be the same: R = 0.72.b. The new correlation coefficient should be R = 0.72 × (2.54/2.2) ≈ 0.83.c. The new correlation coefficient should be R = 0.72 × (2.2/2.54) ≈ 0.62.d. The new correlation coefficient should be something other than the options given here.

Answers

Answer:

a) The new correlation coefficient should be the same: R = 0.72

Step-by-step explanation:

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

It is a relative dimensionless measure, so it does not depend on the units of measurement of the variables involved.

If the variables are correlated in centimeters and kilograms, they will also be correlated in inches and pounds, and with the same relative magnitude.

So the answer is

a) The new correlation coefficient should be the same: R = 0.72

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

A = ( 4⁵ x 4⁻⁷ ) / ( 4⁻² )

Now , from the laws of exponents , we get

m⁻ᵃ = ( 1 / mᵃ )

So , A = ( 4⁵ x 4⁻⁷ ) x 4²

And , mᵃ×mᵇ = mᵃ⁺ᵇ

On further simplification , we get

A = 4⁵⁺²⁻⁷

A = 4⁰

A = 1

Hence , the exponential equation is solved

An oil company fills 1/12 of a tank in 1/3 hour. At this rate, which expression can be used to determine how long will it take for the tank to fill completely? a. 1/12 x 3 hours
b. 1/3 x 12 hours
c. 1/3 x 1/12 hour
d. 3 x 12 hours

Answers

Selection B is appropriate.

_____
It takes 12 times as long to fill the whole tank as it does to fill 1/12 of the tank.
.. 12 * (1/3 hour) = (1/3)*12 hour

Answer: b . $(1)/(3)*12$ hours

Step-by-step explanation:

Given : A oil company fills $(1)/(12)$ of a tank in $(1)/(3)$ hour.

i.e. Time taken to fill $(1)/(12)$ of a tank= $(1)/(3)$ hour.

By using the Unitary method, we multiply 12 on bith the sides of the above expression we get

Time taken to fill $(1)/(12)*12$ tank= $(1)/(3)*12$ hour.

⇒ Time taken to fill 1 tank= $(1)/(3)*12=4$ hour.

Hence, it will take $(1)/(3)*12$ hours or 4 hours for the tank to fill completely.

Thus , the correct answer is b . $(1)/(3)*12$ hours
