Sam created the following incorrect dot plot to represent the data:


What should Sam do to make the dot plot correct?

Put another dot on 13
Put another dot on 16
Delete one dot on 22
Delete one dot on 34

Answer:

33-3 = 30

30 ÷ 5 = 6

Step-by-step explanation:

Kevin has been working as an auto-mechanic. For maximizing weekly income Kevin should do 6 breaks replacement and 4 shock replacements. The time required for performing both the tasks has been equal. Since the time required has been the same, to increase the income, the task resulting in more income has been prioritized

Given :

• The charges for shock replacement = $450,
• The charge for breaks replacement = $200.

Since there have been more income with shock replacement, the brake replacement task has been prioritized.

The time Kevin works in a week has been 42 hours. Since each job takes 2 hours, the number of jobs he can perform has been 21 jobs.

The routine jobsof brake replacement performed by Kevin have been 6. Thus to increase his income, the rest jobs have been of shock replacement.

The number of shock replacement tasks performed by the Kevin =

= 21 - 6

= 15

The number of shock replacement jobs = 15.

Thus for increasing the income Kevin has to perform 6 brake replacement tasks and 15 shock replacement tasks.

Answer:

Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.

Step-by-step explanation:

Both jobs take the same amount of time to complete (2 hours), therefore, in order to maximize his income, Kevin should prioritize the job that gives him the greatest income, which is replacing shocks.

If each job takes 2 hours and he works at most 42 hours per week, Kevin can complete 21 jobs per week. He should aim to do as little break replacements as possible and as many shock replacements as possible to maximize income.

If he completes at least 6 break replacements, the remaining jobs should all be shock replacements:

Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.

Final answer:

To draw four connecting line segments, you need five endpoints. This is because each line segment starts at one point and ends at another, with the end of one segment serving as the start of the next.

Explanation:

In mathematics, a line segment is a piece of a line that has two endpoints. Therefore, to draw one line segment, you need just two endpoints. But drawing four line segments interchangeably (from one endpoint to another) requires five endpoints. Here's why:

• The first line segment starts at the first point and ends at the second point.
• The second starts at the second point and ends at the third point.
• The third starts at the third point and ends at the fourth point.
• The fourth starts at the fourth point and ends at the fifth point.

So, you need a total of five endpoints to draw four line segments that connect with each other sequentially.
