The formula of a midpoint SR:

We have
S(4, 1) and M(7, -5)
Substitute:

<h3>Answer: R(10, -11)</h3>
The probability that they will win their next three games is 51.2%.
The chance that they win is 80%. To find the probability that they win 3 games in a row, we just have to multiply 80% by itself 3 times.
0.8 x 0.8 x 0.8 = 0.512 = 51.2%

Answer:
12:15 is NOT proportional to 3:4
Step-by-step explanation:
7.5:10 is proportional to 3:4 because 3×2.5=7.5, and 4×2.5=10.
39:52 is proportional to 3:4 because 3×13=39, and 4×13=52
45:60 is proportional to 3:4 because 3x15=45, and 4×15=60
12:15 is not proportional to 3:4 because while you can multiply 3x4=12, you can not multiply 4×4 to get 15, you get 16 instead.
