Athirty year old women decides to pay $390 for a one-year life insurance policy with coverage of $150,000. the probability of her living through the year is 0.9976. what is her expected value for the insurance policy?

The expected value is −390(0.9976) + (150,000 − 390)( 1 − 0.9976) = −$30

-$30 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°
