Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
2. What is the MAD for company C's data? Show your work.
3. Which company had the greatest mean number of deliveries?
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Answer:
The means differ by 4 times the MAD.
Step-by-step explanation:
I may be missing something, but this is how I interpret it.
The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.
[tex]14-6=8\\8\div2=4[/tex]
The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.

A 350 mile telephone cable is cut so the shorter piece is 45/55 of the whole cable. How long is each piece?
Two vehicles start from the same point traveling in the same direction. One vehicle travels 55 miles per hour (mph) and the other 45 mph. When will the two vehicles be 350 miles apart?
Answer:
45 x + 55 x = 350
x increases until the total equals 350
45 + 55 = 100 = relative speed of approach
(B) traveling cars meet this equation's specifications (x = 3.5)
The correct statement is option B)
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The equation as 45x+55x=350
A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.
Therefore the relative speed of the two trucks is given by 45+55=100
and let the time taken to meet is x then we can construct an equation as follows x=350/100
or, 45x+55x=350
Hence, The correct statement is option B)

Define a variable, set up an equation, then solve.
Max is already 224 miles into his road trip. If he is averaging 52 miles per hour and the trip is 640 miles total, how many more hours does he have left to drive?
x - hours left to drive
Answer:
8 hours.
Step-by-step explanation:
1. Subtract 640-224=416
2. Divide 416/52
3. 8 hours
8 hours.
Step-by-step explanation:
We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.
Let us find the remaining distance of trip by subtracting the distance already covered from total distance.
Remaining Distance = 640 miles - 224 miles
Remaining Distance = 416 miles
We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.
Time = 416 miles/52 miles/hour
Time = 416 miles/52 × hour/miles
Time = 416/52 hour
Time = 8 hours
Therefore, Max have left 8 more hours to drive.

Step-by-step explanation:
Below is a graph of p, an insect population, w weeks after it was first measured. The population grows exponentially.
Write an approximate domain and range for this situation.
Write an equation relating p and w.
The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]
From the graph, we have the following ordered pairs
(1,900) and (3,8100)
An exponential function is represented as:
[tex]p = ab^w[/tex]
At the point (1,900), we have:
ab = 900
At the point (3,8100), we have:
ab^3 = 8100
Divide both equations
[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]
Evaluate the quotients
[tex]b^2 = 9[/tex]
Take the square roots of both sides
b = 3
Recall that:
ab = 900
So, we have:
3a = 900
Solve for a
a= 300
Hence, the equation is:
[tex]p = 300 * 3^w[/tex]

A property's value decreased by 15%. If is was worth 189,000, what is worth now?
15% of 189000 = [tex] \frac{15}{100} \times 189000 = 28350 \\ [/tex]
So, now it's worth[tex] = 189,000 - 28,350 \\ = 160,650[/tex]
The current worth of the property is $160,650.
What is percentage?Percentage, is a relative value indicating hundredth part of any quantity.
Formula for percent decreasePercent decrease = ( decreased value/ original value) × 100
Therefore,
Decreased value = Original value - new value
According to the question
We have
Percent decrease = 15%
Original value of the property = $ 189,000
So, 15% 0f $189,000 = [tex]\frac{15}{100}[/tex] × 189000
⇒ 15% of 189000 = $28350
Therefore, the decreased value of the property = $189000 - $28350
Decreased value of property = $160,650
Hence, the current worth of the property is $160,650.

Step-by-step explanation:
300 -> 300
added to r -> +
is the same as -> =
217 -> 217
Put this in one equation and you get:
300 + r = 217
If you need to solve for r (need to isolate r to solve for r):
300 + r = 217
r = 217 / (-300)
