Mr. Parker will mix antifreeze and water in a ratio of 2 to 1 he needs 27 quarts of the antifreeze and water mixture to fill his cars radiator how much antifreeze and how much water should mr. Parker mix together ?

answer:

Equation:

2x + x = 27

3x = 27

x = 9 quarts of water

2x = 18 quarts of antifreeze

Step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
