Suppose that 5% of the time Todd attends a concert twice a month, 40% of the time he attends a concert once a month, and 55% of
nikklg [1K]

Answer:

The expected value for the number of times Todd attends a concert during a month is 0.5.

Step-by-step explanation:

We have these following probabilities:

5% probability of attending a concert twice a month, which means that P(X = 2) = 0.05

40% probability of attending a concert once a month, which means that P(X = 1) = 0.4

55% probability of not attending a concert during the month, which means that P(X = 0) = 0.55

What is the expected value for the number of times Todd attends a concert during a month?

We multiply each value by its probability. So

E(X) = 0.05*2 + 0.4*1 + 0.55*0 = 0.1 + 0.4 = 0.5

The expected value for the number of times Todd attends a concert during a month is 0.5.

Harry's mother makes cakes for a local restaurant.She buys flour and sugar in large amounts.She has 157.86 pound of flour and 82
ElenaW [278]

Answer:

<em>The flour will last for about 11 days.</em>

Step-by-step explanation:

Suppose, the flour will last for  x days.

She uses 15 pounds of flour each day. So, <u>the total amount of flour used in x days</u> = 15x pounds.

Given that, she has 157.86 pound of flour. So, the equation will be......

15x= 157.86\\ \\ x= \frac{157.86}{15}=10.524 \approx 11

Thus, the flour will last for about 11 days.

How to tell the difference between direct proportion and inverse proportion
Maksim231197 [3]
If two variables are in direct proportion, then as one increases, the other increases, and as one decreases, the other decreases. An example: If you're working, the amount of money you make (variable y) is in direct proportion to how many hours you work (variable x). The more hours you work, the more money you make, and vice versa. You can put these into the equation y = kx, where k is a constant rate at which x and y are directly proportional. 

<span>If two variables are in inverse proportion, then as one increases, the other decreases, and vice versa. For example: if you take unpaid vacation from work, the number of days taken off (variable x) is in inverse proportion to the amount of money you make (variable y). The more vacation you take, the less money you'll make, and vice versa. You can put these into the equation y = k/x, where k is a constant rate at which x and y are inversely proportional.</span>

Find C round the answer to the nearest hundredth
Tasya [4]

Answer:

48.85 degrees

Step-by-step explanation:

To find the measure of the angle, use the inverse sine function.

Since Sin C = 55/73, so the inverse sine is sin^{-1} \frac{55}{73}.

Using a calculator, the angle is 48.85 degrees.
