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).

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{6\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

Total Surface Area:
2 \times \pi \times r(h + r)2×π×r(h+r)
= 2×22/7×7 (15+7)
= 22×44
= 968 cm sq.or 9.68m sq.
For the second figure :
Diameter = 24cm (radius= 24/2= 12cm)
•Height = 18 cm
Total Surface area:
2 \times \pi \times r(h + r)2×π×r(h+r)
= 2×22/7×12 (18+12)
= 2×22/7×12 (30)

= 2640 cm. sq or 26.4 m.sq
The total surface area of this cylinder is 967.1cm²
Surface area of a cylinder.The formula for calculating the total surface area of a cylinder is expressed as:
TSA = 2πr(r+h)

Answers
Answer:
3/4 of the pot left.
Step-by-step explanation:
If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.

3/4 of the pot is left over

Step-by-step explanation:
Since you know the diameter of the semi circle which is 4 because the shape is a parallelogram, you find the circumference of the circle and divide it by two because we only need to know wheat half of the circumference is. When you do this you end up with the answer 6.28. Then you add the lengths of the parallelogram to 6.28, disregarding the circumference of the circle which isn't part of the perimeter. Doing this is 6.28+6+4+6 which equals 22.28 units.

Step-by-step explanation:
In a parallelogram the diagonals bisect each other making them equal.
this means 2y + 6 = 30
we can rearrange this as 30 - 6 = 2y
24 = 2y therefore y = 12
3x - 3 = 24
We can rearrange this as 24 + 3 = 3x
3x = 27
27 / 3 = 9
x = 9

Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles
Answers
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Beth will cycle a distance of 85.169 miles in the third week.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.
Beth rides her cycle 56 kilometers each week on average.
For the next three weeks, she will increase her distance by 15% each week.
As per the given condition, the required solution would be as
⇒ 56 / 100 = 0.56
⇒ 0.56 × 15 + 56 = 64.4
If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.
Repeat for the remaining three weeks.
⇒ 64.4 / 100 = 0.644
⇒ 0.644 × 15 + 64.4 = 74.06
⇒ 74.06 / 100 = 0.7406
⇒ 0.7406 × 15 + 74.06 = 85.169
Therefore, she will cycle a distance of 85.169 miles in the third week.
