Answer:
6.1389 x 10^8
Step-by-step explanation:
Let event A be the first light being red.
Let event B be the second light being red.
P(A) = 0.48
P(A & B) = P(A) * P(B) = 0.35
P(B) = 0.35 / P(A)
P(B) = 0.35 / 0.48
P(B) = 0.73
Since the lights are independent, P(B|A) = P(B) therefore d is the correct answer.
Answer:
The length of one side of the hot tub is 4.8ft
Step-by-step explanation:
Given
Shape: Square
-- scale factor

Required
Side length of ABCD (the hot tub)
From the question, we understand that
ABCD dilated by 5 to A'B'C'D
This implies that:
i.e. the sides of ABCD is multiplied by 5 to get A'B'C'D
So, we have:

Divide by 5

Answer:
Martha is incorrect.
Amount paid by Renee = 
Amount paid by Susan = $297.5
Amount paid by Martha = 
Step-by-step explanation:
Given: Renee will pay 40% of the cost. Susan will pay 0.35 of the cost.Martha will pay the remainder of the cost. Martha thinks she will pay 13 of the cost.
To find: Is Martha correct?
To find: amount paid by each of Renee, Susan, and Martha
Solution:
Percentage of an amount paid by Renee = 40%
Percentage of an amount paid by Susan = 35%
So,
Percentage of an amount paid by Martha = 
But Martha thinks she will pay 13 of the cost. So, she is incorrect.
Amount paid by Renee = 
Amount paid by Susan = 
Amount paid by Martha =
