(5x10) plus (2x1/100)

2501/50

Decimal:50.02

Step-by-step explanation:

5 × 10 + 2× 1/100

5 × 10 = 50

2 × 1/100 = 1/50

50 + 1/50

50×50. 1

+ ___

50. 50

50 × 50 + 1 = 2501 meaning 2501 over 50 is your answer

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

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
