Question

A company prowhat is the equation of the line of best fit for these data? round the slope and y-intercept of the line to three decimal places. a. y = 1.165x 0.383 b. y = –1.165x 0.383 c. y = –0.383x 1.165 d. y = 0.383x 1.165duces items in small batches. the machinery needs to warm up before the items can be produced. the scatterplot shows the time needed to produce batches of different numbers of items. based on the line of best fit, which of these statements is true?

a. each item requires about 3 minutes of production time.
b. the equipment starts producing items after about 25 minutes of warming up.
c. the equipment starts producing items after about 20 minutes of warming up.
d. each item requires about 12 minutes of production time.

Answer 1

The equation of the line of best fit is y = 1.165x + 0.383. Each item requires about 3 minutes of production time.

Step-by-step explanation:

The equation of the line of best fit is y = 1.165x + 0.383, rounded to three decimal places. This means that for every increase in x by 1 unit, y increases by 1.165 units. The y-intercept, which is the value of y when x is 0, is 0.383.

Based on the line of best fit, the statement 'each item requires about 3 minutes of production time' is true. This can be concluded from the y-intercept, which represents the time needed to warm up the machinery before producing any items.
