Answer:

b. 0.45.

Step-by-step explanation:

The total possible outcome of a probability is 1

Given;

Probability that both lights will be red when she reaches them = 0.22

Probability that the first light will be red and the second light will not be red = 0.33

Probability that the second light will be red when she reaches it = x

These are all the possible outcomes, therefore

0.22 + 0.33 + x = 1

0.55 + x = 1

x = 1 - 0.55

x = 0.45

Blababa [14]

Answer:

$X = $12y

Step-by-step explanation:

In this question, we are asked to give an expression to represent the amount of money charged to a man who stayed in a motel for a particular number of days.

Firstly, we need to know the amount of money charged per day. This is visible from

the question and it is equal to $y.

Secondly, the number of days/night stayed is 12 days. This means that the amount of money he was charged is 12 * y = $12y

Vlad1618 [11]

Answer:

The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest

Step-by-step explanation:

So the formula for this would be:

A = P(1+r/n)^nt

A = the amount of your principal plus interest, which is the total

P = stands for the principal, which is your original amount invested

r = shows the interest rate in decimal form

n =  stands for the number of compounding periods

So to solve for the compound interest we would plug in our numbers in replacement for the letters
