Find the expected value of the winnings from a game that has the following
payout probability distribution:
Payout ($) 0 4 6 8 10
Probability 0.5 0.2 0.15 0.1 0.05

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.

x = 1/2

step-by-step explanation:

hope this !

15 / 2 = 7.5

100 / 7.5 = 13.
