Let P=Perm cost
Let H = Haircut cost
Let L = Lunch cost
Perm costs twice as much as haircut so.. P = 2H
L = 5
H + P + L = 68 the total cost is $68
H + 2H + 5 = 68 since P = 2H and L=5
3H + 5 = 68
3H =63
H = 63/3
H = 21
A Haircut is $21
Perm = 2H = 2(21) = $42
Answer:
the volume of the rectangular prism = 166.336 cubic cm
Hence, option C is correct.
Step-by-step explanation:
We can determine the volume of the rectangular prism using the formula given below.
The volume of the rectangular prism = Base area x Height
<u><em>Determining the Base area:</em></u>
Given
Area of the Base area = l × w
= 3.2 × 4.6
= 14.72 cm²
Thus, the area of the Base area = 14.72 cm²
As the height h = 11.3 cm
Thus,
The volume of the rectangular prism = Base area x Height
= 14.72 x 11.3
= 166.336 cubic cm
Therefore, the volume of the rectangular prism = 166.336 cubic cm
Hence, option C is correct.
Answer:
it should be -4+y
Step-by-step explanation:
The addition of the row and column shows that the number of people polled will be 166.
<h3>How to calculate the number?</h3>
From the information given, the guest thing to do is to add the column. This will be:
= 48 + 118 = 166
Also, it's important to add the row. This will be:
= 69 + 97 = 166
Therefore, the number of people polled will be 166.

Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.
<h3>What is the uniform probability distribution?</h3>
It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.
The probability that Samantha has to wait less than 4.5 minutes to catch the bus is given by:
