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
The expected value for the number of times Todd attends a concert during a month is 0.5.
Answer:
<em>The flour will last for about 11 days.</em>
Step-by-step explanation:
Suppose, the flour will last for 
days.
She uses 15 pounds of flour each day. So, <u>the total amount of flour used in days</u> 
pounds.
Given that, she has 157.86 pound of flour. So, the equation will be......
Thus, the flour will last for about 11 days.
C) you roll a number cube, then flip a coin
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>
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 
.
Using a calculator, the angle is 48.85 degrees.
