<h3>Answer: Choice A) -10.73</h3>

Work Shown:

Plug x = 4.3 into the equation given

ŷ = 2.6 − 3.1x

ŷ = 2.6 − 3.1(4.3)

ŷ = 2.6 − 13.33

ŷ = -10.73

Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.

If the pattern continues how many cups of milk does George need to make 6 batches of muffins

alexdok [17]

Answer:

see explanation

Step-by-step explanation:

If we consider the differences between consecutive terms, that is

$\frac{3}{4}$ - $\frac{3}{8}$ = $\frac{3}{8}$

1 $\frac{1}{8}$ - $\frac{3}{4}$ = $\frac{3}{8}$

1 $\frac{1}{2}$ - 1 $\frac{1}{8}$ = $\frac{3}{8}$

To obtain the next term in the pattern add $\frac{3}{8}$ to the previous term.

batches = 5 ⇒ milk = 1 $\frac{1}{2}$ + $\frac{3}{8}$ = 1 $\frac{7}{8}$

batches = 6 ⇒ milk = 1 $\frac{7}{8}$ + $\frac{3}{8}$ = 2 $\frac{1}{4}$

Answer:

8.333333

Step-by-step explanation:

3x+2(4+6x)=133

3x+8+12x=133 First I distibuted the 2 too the 4 and 6x

15x+8=133 Then I added the x es 3x and 12x

15x+8-8=133-8 Then I subracted 8 from both sides

15x=125 That leaves with this

15x/15=125/15 Now I divide 15 from both sides to isolate x

x= 8.33333 that is the answer

check

3x+2(4+6x)=133

3*8.333333+2(4+6*8.333333)=133

24.999999 +2(4+ 49.999998)=133

24.999999+2( 53.999998)=133

24.999999+107.999996=133

132.999995=133
