Answer:

To get the Greates Common Factor (GCF) of 132 and 432 we need to factor each value first and then we choose all the copies of factors and multiply them:

132: 2 2 3 11

432: 2 2 2 2 3 3 3

GCF: 2 2 3

The Greates Common Factor (GCF) is: 2 x 2 x 3 = 12

Answer:

Step-by-step explanation:

Find the prime factorization of 132

132 = 2 × 2 × 3 × 11

Find the prime factorization of 432

432 = 2 × 2 × 2 × 2 × 3 × 3 × 3

To find the gcf, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 2 × 3

GCF = 12

scoundrel [369]

Answer:

12 hr. mowing lawns

28 hr. working at Mc Donalds

Step-by-step explanation:

Let t = time mowing lawns

then 40 - t = time working at McDonalds

7,5(40 - t) + 6t = 282

300 - 7.5t + 6t = 282

-1.5t = -18

t = 12 hr. mowing lawns

40 - t = 40 - 12 = 28 hr. working at Mc Donalds

What is the slope of the line shown in the graph? <br> A.-3/2<br> B.-1/2<br> C.3/2

Varvara68 [4.7K]

I think answer is A
Because slope=rise/run
Rise is 3
Run is 2
But it will be negative because of the direction of slope

Using Multiple regression, the relationship of Y to four other variables was established as: Y = 12 + 3X₁ – 5X₂ + 7X₃ + 2X₄ When

alexdok [17]

Answer:

The estimate of Y changes by -2 or decreases by 2.

Step-by-step explanation:

We are given the following information:

Using Multiple regression, the relationship of Y to four other variables was established as:

$Y = 12 + 3X_1- 5X_2 + 7X_3 + 2X_4$

$X_1$ increases 2 units and $X_2$ increases 1 unit, while $X_3$ and $X_4$ remain unchanged.

Predicted Y =

$Y_p = 12 + 3(X_1+2) - 5(X_2+1) + 7X_3 + 2X_4$

Change in Y =

$Y_p - Y \\= 12 + 3(X_1+2) - 5(X_2+1) + 7X_3 + 2X_4-(12 + 3X_1 - 5X_2 + 7X_3 + 2X_4)\\= 12-12+3(X_2+1-X_2)-5(X_2+1-X_2) + 7X_3 - 7X_3 + 2X_4 - 2X_4\\=3 - 5\\= -2$

The estimate of Y changes by -2 or decreases by 2.
