Δy/Δx is nothing but the slope and slope = rise/run .

Look up in the FIRST graph; From the lower point on the line draw a // to x-axis and from the higher point draw a // to y-axis. Note the point of intersection, their coordinates are (6, 3) [ x=6 = run and y= 3 = rise)
Or Δy = rise = 6    and Δx = run = 3, hence Δy/Δx  = 6/3 = 1/2 = slope.

Do the same thing with the 2nd graph:
Δy = 3 and  Δx = - 2 (you are counting from right to left), then 

Δy/Δx = 3/(-2)  and Δy/Δx = -3/2

You own a company that employs three salespeople, Quentin, Michael and Bubba. Quentin makes 30% of the sales, Michael 45%, and B
borishaifa [10]

Answer:

Michael

Step-by-step explanation:

Look at the table below:

The probability of selecting a sale that was made by Quentin is .30, by Michael is .45 and by Bubba is .25.

Since Quentin completes paperwork 90% of the time, he doesn't complete paperwork 10% of the time, following this reasoning we can say that Michael doesn't complete paperwork 20% of the time and Bubba doesn't complete paperwork 15% of the time.

The probability of selecting a file and that it belongs to Quentin AND is incomplete is:

(Probability of selecting a Quentin's file) x (Probability is a Quentin incomplete file) = (0.30)(0.10) = 0.03

Using this same method we have that the probability that it belongs to Michael and is incomplete is (.45)(.20) = 0.09

That it belongs to Bubba and it's incomplete is (0.25)(0.15) = 0.037

The highest of these probabilities is the one that corresponds to Michael: 0.09, therefore he is the most likely culprit.

A rectangular prism has a length of 8 in., a width of 4 in., and a height of 2 1/4 in.
marishachu [46]

The number of cubes needed to fill the rectangular prism 4608 cubes.

<h3>How to find volume of rectangular prism and cube?</h3>

volume of rectangular prism = lwh

where

  • l =length
  • w = width
  • h = height

Therefore,

volume of the rectangular prism = 8 × 4 × 9 / 4 = 72 inches³

volume of the cube = l³

where

  • l = length

Therefore,

volume = (1 / 4)³

volume of the cube = 1  / 64 inches³

Therefore,

The number of cubes needed to fill the rectangular prism = 72 ÷ 1 / 64

The number of cubes needed to fill the rectangular prism = 72 × 64 = 4608
