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

Answer: ∠R = 137°

<u>Step-by-step explanation:</u>

The opposite angles of a quadrilateral are supplementary (equal to 180°).

Since ∠P and ∠R are opposite angles, their sum is 180°

∠P + ∠R = 180°

y + 3y + 8 = 180

4y + 8 = 180

4y = 172

y = 43

∠R = 3y + 8

= 3(43) + 8

= 129 + 8

= 137

Lines AB and CD intersect at P. PR−→− is perpendicular to line AB, and the measure of ∠APD is 170°. A series of intersecting lin

liraira [26]

Answer:

The correct answer is option A.

Step-by-step explanation:

Given : line AB intersect CD at P. PR is perpendicular to AB.

∠APD = 170°

To find = ∠DPB =?

Solution :

line AB intersect CD at P:

So,∠APD =∠BPC = 170° ..[1]

(vertically opposite angles of two straight lines intersecting at common point are equal)

On line CD two angles are ∠BPC ,∠DPB

∠BPC + ∠DPB =180° (supplementary angles)

170°+ ∠DPB =180°

∠DPB =180° - 170° = 10°

So, the measure of ∠DPB is 10°.

Reese's truck can go 1,040miles on a full tank of 52gallons of gas. Find the rate of miles per gallon.

Vesna [10]

Answer:

Step-by-step explanation:

Since the truck goes 1040 miles and costs 52 gallons of gas every tiime it goes 1040 miles, we can divide 1040 by 52 to see how far 1 gallon of gas will get you. 1040/52=20 so every 20 miles cost 1 gallon of gas
