Several psychology majors conducted an experiment around campus, asking students to count backwards from 40 to 0 as fast as poss

ible. From their findings, they concluded that out of every 15 students, only 6 could accurately count backwards in less than 15 seconds. They repeated this experiment with the professors. They discovered that their success rate was 140% of the students' success rate. From the list of participants, they randomly selected 10 students and 10 professors. The probability that 4 students who completed the task were selected is S and the probability that 4 professors who completed the task were selected is R. Find the absolute difference in S and R.

(8, 1) and (-1, 10)<br> Slope
gizmo_the_mogwai [7]

Answer:

<h2>The answer is 1</h2>

Step-by-step explanation:

The slope of the line between two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}

where

(x1 , y1) and (x2 , y2) are the points

From the question is points are

(8, 1) and (-1, 10)

Substitute the values into the above formula and solve for the slope

That's

m =  \frac{10 - 1}{8 + 1}  \\  =  \frac{9}{9}   = 1

We have the final answer as

<h3>1 </h3>

Hope this helps you
