Me fast! if given good answers will mark as brainliest!

1) the local ice cream shop is deciding whether or not to hire a new worker. the shop must pay the worker hourly and cover a daily cost for insurance. the cost to pay an hourly worker for one day is represented by the function
y= 9.25x + 15, where x is hours. what is the slope, and what does it represent. show your work.

2) the correlation coefficient for poor health and not exercising in a group of people is 0.52. analyze the following statement: based on the correlation coefficient, is this a reasonable conclusion. explain why or why not.

3) analyze the following statement:
marcus notices that he runs faster in the mornings rather than evenings. is this statement and example of correlation or causation? explain your answer!

Step-by-step explanation:

1. Given that the local ice cream shop is deciding whether or not to hire a new worker. The shop must pay the worker hourly and cover a daily cost for insurance. The cost to pay an hourly worker for one day is represented by the function y=10x+30 where x=hours.

We find that this is of the form y = mx + B where

m = 10 and B = 30

Hence slope = m = 10

Answer is 10,

and it represents the rate of change of y for a unit change in x.

2. The answer is the third option "No; the data doesn't suggest a causation, and many people are healthy who don't exercise." Correlation is two data set that are linked or connected together so in this case it would be a correlation because all of the data is close and connected to each other.

3. The answer is "Correlation, because time of day doesn't cause a person to run faster or slower ".

That's the correct answer because causation would mean there is a cause and effect and in the question, there is no cause. It can't be the last one because there is enough information. It also can't be the third one because there is a relationship since he shown he runs faster in the evening. Also I took the test and it was right!

just sum

10 + 10 = 20
