A store employee performs most of the daily unit counts, but the owner personally recorded that there were 61 units remaining after 3 days and 33 units remaining after 13 days.

THE COMPLETE QUESTION IS:

A store employee performs most of the daily unit counts, but the owner personally recorded that there were 61 units remaining after 3 days and 33 units remaining after 13 days. Use these two data points to determine the equation for the line of best fit for the store's inventory. Write the answer in decimal form.

y = __x + __

The equation for the line of the best fit for the store's inventory is given as:

y = -2.8x + 69.4

Step-by-step explanation:

The owner recorded that:

1. There were 61 units remaining after 3 days.

This can be written as (x, y) = (3, 61)

2. There are 33 units remaining after 13 days.

This can be written as (x, y) = (13, 33)

Together, the data points are:

x1 = 3

x2 = 13

y1 = 61

y2 = 33

We want to write these in the form

y = mx + c

Where m is the slope, and c is constant.

Let us obtain the slope using the formula

m = (y2 - y1)/(x2 - x1)

= (33 - 61)/(13 - 3)

= -28/10

= -2.8

m = -2.8

Now, we substitute into

y = mx + c

Using any of the points, we can obtain the constant c.

Let us use (13, 33)

Where x = 13, y = 33

We now have

33 = -2.8(13) + c

c = 33 + 36.4

c = 69.4

Finally, the equation becomes

y = -2.8x + 69.4

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
