PLEASE HELP (06.07 HC)

A manager is assessing the correlation between the number of employees in a plant and the number of products produced yearly. The table below shows the data:

Number of employees

(x) 0 50 100 150 200 250 300 350 400

Number of products

(y) 100 1,100 2,100 3,100 4,100 5,100 6,100 7,100 8,100

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

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

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

a

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.

answer: 1/2=3/6=4=8

step-by-step explanation:

3/6= 1/2

4/8=1/2

approximately 5 hours 32 minutes

let x be the amount of it takes both pumps to fill and 1 pump to empty

so the pumps fill/empty at the rate of per hour

first pump fills at a rate of per hour

second pump fills at a rate of per hour

third pump empties at a rate of per hour

together the reservoir fills at a rate of

+ - =

multiply each term by 720x

120x + 90x - 80x = 720

130x = 720 ( divide both sides by 130 )

x = = 5. hours

(0. × 60 ≈ 32 minutes )

time taken to fill reservoir is 5 hours 32 minutes
