Answer:

66°

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

x + y = z

5n − 19 + n + 7 = 144 − 6n

6n − 12 = 144 − 6n

12n = 156

n = 13

m∠z = (144−6n)°

m∠z = (144−6×13)°

m∠z = 66°

) The correlation between a car’s engine size and its fuel economy (in mpg) is r= -0.774. What fraction of the variability in fu
Zolol [24]

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%.

10 POINTS so easy if you are ish smart WILL MRAK BRAINLEST SUPER EASY ISH NOT FOR ME THOUGH
IrinaK [193]

Answer:

Step-by-step explanation:

A]

Both have the same surface area. The numbers are just rearranged.

B]

Is the correct answer.

The surface area of the first one is 2*8*5 + 2*8*6 + 2*5*6 = 236

The surface area of the second is 2*10*8 + 2*10*3 + 2*8*3 = 244

C]

Another rearrangement. Not the answer.
