8 0

yea it is because when u set it up 3/8=12/32

I put the x in the 32's spot

then I completed the procedure by multiplying straight across to the two numbers across from each other 8*12= 96 then u take the number across from the x and divide so it would be 96 /3 = 32 which states tht they r equivalent

Run a multiple regression where the dependent variable is ratings and the independent variables are star and fact. Use data from

Vanyuwa [196]

Answer:

See explaination

Step-by-step explanation:

See attachment for diagram

The r value is 0.373 (low). This implies a weak correlation between the dependent and independent variables for this sample.

The overall p- value for the regression model is 0.0017. This implies that at least one of the two independent variables (x1 or x2) in the model is significant predictor of the dependent variable y.

p- values for the both "Fact" and "Star" are < 0.05. This means both the independent variables are significant predictors of the "Rating" at 95% confidence level. The variable "Fact" is significant at 99% level of confidence also. This means the rating viewers award to a movie depends upon both the storyline (fact or Fiction) and the presence or absence of stars.

Expected rating for a fact based movie with no stars = 1.7991(1) + 1.2586(0) + 12.5685 = 14.37

Expected rating for a fiction based movie with a star = 1.7991(0) + 1.2586(1) + 12.5685 = 13.83

So, one may expect a fact based movie without any stars to get better ratings than a fiction based movie with one star.

The larger of two numbers is five more than the smaller. Twice the larger is twenty less than four times the smaller. Find the n

lesantik [10]

Answer: Small number = 15.

Larger number = 20

Step-by-step explanation:

Let the smaller number be x.

The larger of two numbers is five more than the smaller. Thus, the larger number is x+5.

Twice the larger is twenty less than four times the smaller. This can.be written as:

2(x + 5) = 4x - 20

2x + 10 = 4x - 20

2x - 4x = -20 - 10

-2x = -30

x = 30/2

x = 15

The smaller number is 15

Larger number = x + 5 = 15 + 5 = 20

Help pleaseee !! Equation work

Lina20 [59]

-11.2 + 4(2.1 + q) = -0.8

-11.2 + 8.4 + 4q = -0.8

4q = -0.8 + 11.2 - 8.4

4q = 2

q = 1/2 Answer

3x = -9

x = -9 / 3

One month kris rented 3 movies and 8 video games for a total of $53. the next month she rented 5 movies and 2 video games for a

SCORPION-xisa [38]

Make a system of equations and solve for each variable.

3m+8v=53
5m+2v=26

m= movie cost
v= game cost

multiply the bottom equation by 4(combination method)

3m+8v=53
20m+8v=104. Subtract

-17m = -51
m= 3

Plug back into one of the equations

5(3)+2v=26
15+2v=26
2v=11
v=5.5

m=$3
v=$5.5
