Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). Heavier cars tend to have lower fuel efficiencies (lower mpg ratings). Which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context? A. Weight B. Fuel efficiency

Answers

Answer:

Correct option: A. Weight.

Step-by-step explanation:

In regression analysis there are two kinds of variables: Explanatory and Response variable.

The explanatory variable are used to predict the changes in the response variable. They are also known as independent or predictor variable.

The response variable are observed for any changes caused by the explanatory variable. They are also known as the dependent or experimental variable.

In this case it is provided that heavier cars have lower fuel efficiencies.

It implies that there is linear inverse relationship between the variables weight of the car and fuel efficiency.

The response variable is the fuel efficiency and the explanatory variable is the weight of the car. Since the weight of the car is used to determine the fuel efficiency.

Thus, the explanatory variable is the weight of the car.

Final answer:

The explanatory variable in this context is the weight of the car, as it is used to predict or explain the car's fuel efficiency.

Explanation:

In this context, the most naturally considered explanatory or predictor variable would be the weight of the car. This term is used to denote the variable that is used to predict or explain changes or variations in another variable. In this case, the weight of the car is used to predict or explain the fuel efficiency (measured in miles per gallon). For instance, if the weight of a car increases, we would expect the fuel efficiency to decrease (lower mpg) because heavier cars often require more energy to move, which in turn results in higher fuel consumption.

What are the solutions of this quadratic equation?
x2 − 10x = -34

Answers

The roots of the equation are imaginary numbers, 5+6i, 5-6i.

What is a Quadratic Equation?

A quadratic equation is what can be written in the form of ax²+bx+c=0

The quadratic equation is

x² -10x = -34

x² -10x +34 = 0

The roots formula for a quadratic equation is given by

$x = ( -b \pm √(b^2 -4ac))/(2a)$

Here a = 1

b = -10

c = 34

The roots of the equation are

$x = ( 10 \pm √((-10)^2 -4*34))/(2)$

$\rm x = ( 10 \pm √(-36))/(2)\n\n\nx = 5 \pm 6i$

A Gentoo penguin can swim at a rate of 17 miles per hour. How many miles can a penguin swim in four hours. Use the expression rt, where r represents rate and t represents time

Answers

Penguin can swim 68 miles in four hours.

What is Rate?

A rate is defined as the ratio which is used to compare two different types of quantities that have different units.

Unit rate defines the ratio of the amount of one quantity with respect to the single unit of the other quantity. Or in other words, the denominator of unit rate will be always 1.

Here we have the unit rate as 17 miles per hour.

Here unit rate is defined in terms of distance covered per time which is actually the speed of penguin.

We have to the distance covered by the penguin in 4 hours.

Rate = Distance / Time

⇒ Distance = Rate × Time

= 17 × 4

= 68 miles

Hence, penguin can swim 68 miles in 4 hours if the rate of swimming is 17 miles per hour.
