Answer:
66.8
Step-by-step explanation:
Try only multiplying 16 and 4, then 0.7 and 4, then add them all up.
Answer:
3.8
Step-by-step explanation:
1.8 + 3.6 = 5.4
5.4 - 9.2 = 3.8
Answer:
(C) 4
Step-by-step explanation:
I am going to solve this by trial and error:
(A) 1
Is: 
?
So 1 is not the digit of N.
(B) 2
Is: 
?
So 2 is not the digit of N.
(C) 4
Is: 
?
Correct, so the answer is c.
(D) 5
(E) 6
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%.
