Answer:
a) 148.52
Step-by-step explanation:
If sum of two angles is 180, then they are supplementary
Ratio = 10 : 47
Smaller angle = 10x
Larger angle = 47x
10x + 47x = 180
57x = 180
Divide both sides by 57
x = 180/57
x = 3.16
Larger angle = 47x = 47 * 3.16 = 148.52
So... we have two numbers
say "a" and "b"
one is larger than the other, let us say, "b" is larger than "a"
by how much?
well, "<span>eight more than three times"
three times the smaller is 3 * a, or 3a
eight more than that is 3a + 8
so b = 3a+ 8
the sum of both of them is 52
so, we know that
a + b = 52
run a substitution on "b" on the 2nd equation, and solve for "a"
once you find "a", plug it back in the 2nd equation, to get "b"

Answer: −1.409
Step-by-step explanation:
Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013
Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118
Probability of other draw: 1 - 0.013 - 0.118 = 0.869
0.013 * (50 - 5) = 0.585
0.118 * (25 - 5) = 2.353
0.869 * (0 - 5) = -4.347
Expected value: 0.585+ 2.353 - 4.347 = -1.409
