Answer:

330ft²

Step-by-step explanation:

Area of figure = Area of rectangle + Area of semicircle

                       =            lb                +   pi r²/2

                       =         10 x 8             +  3.1 x 4 x 4/2 ( as 8 is diameter)

                       =          80 ft²               +  248  ft²

                       =  328 ft² => 330ft²

An investment counselor calls with a hot stock tip. he believes that if the economy remains​ strong, the investment will result
anzhelika [568]

Answer: $ 16,000 profit

Step-by-step explanation:

Given the following :

Profit when economy is strong = 50,000

Profit when economy is moderate = 10,000

Loss when economy goes into recession = 50000

Resulting probabilities of the three probable occurrences are:

Probability of strong economy; p(strong) = 30/100 = 0.3

Probability of moderate; P(moderate) = 60/100 = 0.6

Probability of recession; P(recession) = 10/100 = 0.1

Expected profit :

Summation of the product of each probability and its accompanying profit or loss.

P(strong) × profit of strong = 0.3 × 50000 = 15000

P(moderate) × profit of moderate = 0.6 × 10000 = 6000

P(recession) × loss on recession = 0.1 × 50000 = 5000 = - 5000 ( loss)

Expected profit :

$(15,000 + 6000 - 5000) = $16,000 profit
