I think he pays $702.
Basically,
650 • .08 (move the decimal over two to the left, that’s what you get) = 52. Then I did 650 + 52 and got $702.
We find the volume of the ball in cubic inches:
V = 4/3 πr³
V = 4/3 x π x 5³
V = 523.6 cubic inches
Weight = 1/100 x 523.6
Weight = 5.24 pounds.
Factorize the numerator and denominator, then simplify:
10/45 = (2×5)/(9×5) = 2/9
Now,
1/9 = 1/10 + 1/90
1/90 = 1/10 × 1/9 = 1/10 × (1/10 + 1/90) = 1/100 + 1/900
1/900 = 1/100 × 1/9 = 1/100 × (1/10 + 1/90) = 1/1000 + 1/9000
and so on, which is to say
1/9 = 1/10 + 1/100 + 1/1000 + …
or
1/9 = 0.111…
so that multiplying both sides by 2 gives
2/9 = 0.222…
2.80/7=.4 then add .75
.40+.75=1.15 each cookie is 1.15$
C) Moe highest probability=14, median (50% of the values), mean=central measure of the '50%' all are 14-15, C) is the closest, no? :)
