Utility companies usually charge their customers based on the number of kilowatt-hours their customers consume in a period. Suppose the function A(p)=0.096p+19.50 represents the monthly charge, A, in dollars for a customer with Electric Company A consuming p kilowatt-hours of power. The function B(p)=0.104p+17.75 represents the monthly charge, B, in dollars for a customer with Electric Company B consuming p kilowatt-hours of power. Analyze the functions by interpreting the slope and y-intercept for each function in terms of the context for this situation. Then assess how the slope and y-intercept of Electric Company A compare with the slope and y-intercept of Electric Company B in this situation.
Step-by-step explanation:
A(p) = 0.096p + 19.50
Company A charges a monthly fee of $19.50, and charges a rate of $0.096 per kilowatt-hour of energy.
B(p) = 0.104p + 17.75
Company B charges a monthly fee of $17.75, and charges a rate of $0.104 per kilowatt-hour of energy.
Company A has a higher monthly fee, and company B has a higher rate.

A woman traveled 2440.2 miles in 17 hours 15 minutes. Find the average speed of her flight in miles per hour. (Change 17 hours 15 minutes into hours and use the
formula d=rt.)
Answer in the format of: “The average speed of the woman's flight was ____mph”
Answer:
141.46 mi/h
Step-by-step explanation:
d = rt
r = d/t = (2440.2 mi)/(17.25 h) ≈ 141.46 mi/h
The woman's average speed was about 141.46 mph.
6 points Emily’s family needs to rent a moving truck to move their belongings to a different house. The rental cost for Trucks-A-Lot is $42 per day plus $0.72 per mile. The rental cost for Move-It-Truckers is $70 per day plus $0.12 per mile. Let m represent Emily’s mileage. Write an equation to represent the cost of renting each truck, and determine what will be the number if miles for which the truck cost the same amount.
Answer/Step-by-step explanation:
Equation to represent the daily rental cost for each type of truck can be written as follows:
Daily rental cost for Trucks-A-Lot = 42 + 0.72m
Daily rental cost for Move-in-Truckers = 70 + 0.12m
Where, m = Emily's mileage
To determine the number of miles for which the truck cost the same amount, set both equations equal to each other and solve for m.
[tex] 42 + 0.72m = 70 + 0.12m [/tex]
Collect like terms
[tex] 0.72m - 0.12m = 70 - 42 [/tex]
[tex] 0.6m = 28 [/tex]
Divide both sides by 0.6
[tex] \frac{0.6m}{0.6} = \frac{28}{0.6} [/tex]
[tex] m = 46.7 [/tex]
At approximately 47 miles, both trucks would cost the same amount.
Check:
Daily rental cost for Trucks-A-Lot = 42 + 0.72m
Plug in the value of x = 47
= 42 + 0.72(47) = $75.84 ≈ $76
Daily rental cost for Move-in-Truckers = 70 + 0.12m
Plug in the value of x = 47
= 70 + 0.12(47) = $75.64 ≈ $76

What questions do you still have about what we’ve learned
At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 97 miles per hour (mph) and the standard deviation of the serve speeds was 10 mph. If nothing is known about the shape of the distribution, give an interval that will contain the speeds of at least three-fourths of the player's serves.
A) 87 mph to 107 mph
B) 117 mph to 137 mph
C) 67 mph to 127 mph
D) 77 mph to 117 mph
Answer: D) 77 mph to 117 mph
Step-by-step explanation:
Given that:
Mean serve speed(m) = 97 miles per hour
Standard deviation of serve speed = 10 mph
Shape of distribution is not known ; interval that will contain the speeds of at least three-fourths of the player's serves
Using Chebyshev's rule:
(1 - 1/k²) = 3 / 4
1 / k² = 3/4 - 1
- 1/k² = - 1 / 4
1/k² = 1/4
Cross multiply:
k² = 4
Square root of both sides :
k = 2
Hence, number of standard deviation = 2
(-k*sd) + m ; (k*sd)+m
(-2*10) + 97 ; (2*10)+97
-20 + 97; 20 + 97
77 ; 117
77mph ; 117mph

What is the area of square and a rectangle?The area of the square and rectangle is -
Square = [x]² {x is the side of a square]
Rectangle = L x B {L is the length and B is breadth}
Given is Lisa who is decorating outside edge of a square picture frame. She needs to know the side length of the frame. The area of the frame is [m] square inches.
It is given that the the area of the square is [m] square inches.
Assume that the length of the side is [x] inches.
x² = m
x = ±√m
Side cannot be negative. Therefore, the side of the length will be -
x = √m
Therefore, the side of the length will be x = √m square inches.
