Answers
Answer:
Then you have infinite solutions
Step-by-step explanation:
if no solution, you would get sum lyke 4 = 5
if infinite soltution you would get sum lyke 3 = 3
if you have one solution, expect to get sum lyke x = 5

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?
Write your answer in the space below.
2. What is the MAD for company C's data? Show your work.
Write your answer in the space below.
3. Which company had the greatest mean number of deliveries?
Write your answer in the space below.
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Write your answer in the space below.
Answers
Answer:
Step-by-step explanation:
1. the company C used 10 drivers
2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/10
3. The groups that had the most deliveries where group A and B
4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4
By reading the dot plot,
Number of drivers used by company C in its sample = 10
Mean absolute deviation for company C's data = 2
Company B has the greatest mean number of deliveries.
The mean deliveries of company B is 4 times MAD of company A.
What is dot plot?Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.
Number of units used in the sample of a dot plot can be calculated by simple counting.
What is mean absolute deviation?The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.
We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.
Mean absolute deviation of company C = 20/10 = 2.
Mean A = 6
Mean B = 14
Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

x = {-0.44, 1.69}
Step-by-step explanation:
Multiply by the denominator to eliminate the fraction.
3 = x(4x -5)
4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form
Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-5)\pm\sqrt{(-5)^2-4(4)(-3)}}{2(4)}\\\\x=\dfrac{5\pm\sqrt{73}}{8}\approx \{-0.443, 1.693\}[/tex]

Jack had $200 when he got to the festival. He spends $4 per ride. The equation T = 200 – 4R models his amount of money. If he has $100 left how many rides did he go on
Answers
Answer:
25
Step-by-step explanation:
Given the equation :
T = 200 - 4R
T = amount of money left ; if T = $100
R = number of rides
$100 = 200 - 4R
$100 - $200 = - 4R
-$100 = - 4R
R = 100/ 4
R = 25
25 rides

a certain number of two digit is three times the sum of its digit and if 45 added to it the digit will be reversed find the number ?
Answers
Let the number be (10 x + y)
Then, 10 x + y = 3 * (x + y) (given)
Or, 10 x + y = 3 x + 3 y
Or, 10 x - 3 x = 3 y - y
Or, 7x = 2 y
Or, x = 2 y / 7 ( Eq. 1)
Also, 10 x + y + 45 = 10 y + x ( given)
Or, 10 x - x = 10 y - y - 45
Or, 9 x = 9 y - 45 ( Eq. 2)
Substituting the value of x from (Eq. 1) in (Eq. 2), we have:
9 * 2 y / 7 = 9 y - 45
Or, (9 y ) - (18 y / 7) = 45
Or, 63 y - 18 y = 315
Or, 45 y = 315
Or, y = 7
From (Eq. 1),
x = 2 * 7 / 7 = 2
So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27
Answer
Check:
Sum of the digits = 2 + 7 = 9
9 * 3 = 27 ✓
Adding 45 to the number 27, we get 72. So, the digits get reversed.
