Look at the diagram. If RS = 15 and RT = 18, then ST =

ST = 3

Step-by-step explanation:

If points R, S, T are collinear and R - S - T only then:

RS + ST = RT

ST = RT - RS

ST = 18 - 15

ST = 3

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

for a it would be 24 children.
