Deffense [45]

Answer:

The F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.

Step-by-step explanation:

There are four treatments in the data given, i.e. k = 4.

Total number of observations, n = 12.

Note: degrees of freedom is denoted as df.

For treatment, the degrees of freedom = k-1 = 4-1 =3 df.

The total degrees of freedom = n-1 = 12-1 = 11 df.

The error in degrees of freedom = df (total) - df(treatment)

The error in degrees of freedom = 11 - 3 = 8 df

At α = 0.05 level,from the F table, the F-statistic with (3 , 8)df is 4.07.

Therefore, the F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.

How to find the equation of this line?

Bad White [126]

Answer:

y = - $\frac{6}{7}$ x - $\frac{10}{7}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 4, 2 ) and (x₂, y₂ ) = (3, - 4) ← 2 points on the line

m = $\frac{-4-2}{3+4}$ = - $\frac{6}{7}$ , thus

y = - $\frac{6}{7}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 4, 2 ), then

2 = $\frac{24}{7}$ + c ⇒ c = 2 - $\frac{24}{7}$ = - $\frac{10}{7}$

y = - $\frac{6}{7}$ x - $\frac{10}{7}$ ← equation of line

Do you guys the answer for number 3

ohaa [14]

Answer:

the answer is L. or the last answer

Step-by-step explanation:

you have to find the total area of the place first...

which is 21*17=357

then subtract the inner area (white area) which is

14*20=280

do 357-280 to get the remaining area and the answer is 77ft^2

hope this helps.. vote, comment, thanks, and maybe mark me brainliest lol idk
