Answer:

$0.558

Step-by-step explanation:

The expected value is the sum of the value of each outcome times the chance that it happens. In this case, there are two outcomes:

Win $31 million
Win $0

Then our expected value can be calculated as:

$EV=(31,000,000)(0.000000018)+(0)(1-0.000000018)=0.558$

In the figure to the right, ABCD is a rectangle. Find the area of △ABC, if the area of △AOD is 10.

ehidna [41]

Assuming BOD and AOC are straight lines.

Area of the rectangle = 4 x ΔAOD
Area of the rectangle = 4 x 10
Area of the rectangle = 40 unit²

Area of ΔABC = 1/2 x 40
Area of ΔABC = 20 unit²

A poster is 3 inches long. it is 4 times as wide as it is long find the perimeter and area of the poster?

iren [92.7K]

So we know that the width is 12 because 4 x 3 = 12. The formula to find the perimeter is Length + length + width + width. So you would do 3 + 3 + 12 + 12 = 30. Therefore the perimeter is 30 inches

solve -9p - 5m = 60 how do you solve this step by step please. not just the answer I need to learn how you do this problem. solv

Scrat [10]

-9p - 5m = 60
-9p - 5m + 5m = 5m + 60
-9p = 5m + 60
-9 -9
p = ⁻⁵/₉m - 6²/₃

You have to add 5m on each side in order to find the value of p. then, you have to divide it by -9 in order to find the value of p.
