Answer:
75 feet
Step-by-step explanation:
If the circumference of the wheels is 5 feet, every full rotation the bike will travel 5 feet. Therefore, after 15 full rotations the bike will travel 15 * 5 = 75 feet.
The fraction of the variability in fuel economy is accounted for by the engine size is 59.91%.
Given that, r= -0.774.
To solve such problems we must know about the fraction of the variability in data values or R-squared.
<h3>What fraction of the variability in fuel economy is accounted for by the engine size?</h3>
The fraction by which the variance of the dependent variable is greater than the variance of the errors is known as R-squared.
It is called so because it is the square of the correlation between the dependent and independent variables, which is commonly denoted by “r” in a simple regression model.
Fraction of the variability in data values = (coefficient of correlation)²= r²
Now, the variability in fuel economy = r²= (-0.774)²
= 0.599076%= 59.91%
Hence, the fraction of the variability in fuel economy accounted for by the engine size is 59.91%.

Answer:
10,36,3,144,6 and 24 in that order
Step-by-step explanation:
sorry if its wrong
The value of a, b and c can be calculated using the inverse function.
The calculated the value of a= 2, b=1 and c= -2.
Given:
The function is
and its inverse is
.
<h3>What is an inverse function?</h3>
- The inverse function of a function is defined if
is a function that undoes the operation of
.
- The inverse of
exists if and only if
is bijective, and if it exists, is denoted by
.
Substitute the value of x= -1 in a given inverse function and calculate the value of a.

Substitute the value of x is 0 in given inverse function.

Substitute the value of x is 2 in given inverse function.

Therefore, the value of a= 2, b=1 and c=-2.
