Question

PLSSS I NEED HELP I'LL GIVE WHOEVER ANSWER CORRECTLY BRAINLIST!!! manager is assessing the correlation between the number of employees in a plant and the number of products produced monthly. The table shows the data:
Number of employees

(x) 0 10 20 30 40 50 60 70 80

Number of products

(y) 120 200 280 360 440 520 600 680 760



Part A: Is there any correlation between the number of employees in the plant and the number of products produced monthly? Justify your answer. (4 points)


Part B: Write a function that best fits the data. (3 points)


Part C: What does the slope and y-intercept of the plot indicate? (3 points)

Answer 1

Answer:

A - There is a correlation between the number of employees in the plant and the number of products produced monthly. You can see that on the table, the number of products is increasing by 80 for every 10 employees added.

B. f(x) = 8x (rate changing) + 120 (starting number)

C - The slope indicates the number of products increasing each time, which is 80 but since the rule is y/x it becomes 8. The y-intercept is the starting amount of products, which is 120.

Explanation:

Find out the rate of change on both sides (x and y). On X, the change is 10. For Y, the change is 80. To find out the slope, we must do Y/X which is 80/10 and that leaves us with 8.

Answer 2

Answer:

a) yes. when no. of employees (x) are increasing, number of products produced monthly(y) increasing according to table

b)y=8x+40

c)slope=8

  intercept=40

Step-by-step explanation:

b) y-y1=m(x-x1)

   (200-120)=m(20-10)

   80=m(10)

    m=80/10

    m=8

y=mx+c

120=8*10+c

c+80=120

c=40

y=8x+40
