<h3>
Answer: Slope = -3/7</h3>
===================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (6-3)/(-9-(-2))
m = (6-3)/(-9+2)
m = 3/(-7)
m = -3/7
This means each time you go down 3 units, you go to the right 7 units.
Slope = rise/run = -3/7
rise = -3 and run = 7
Answer:
i know this isn't answering but this will help
Step-by-step explanation:
try the graphing Calculator app called Desmos
its free to use and easy to understand
hope this helped
With
a standard deviation of 6 minutes, we will test the hypothesis that σ = 6
against the alternative that σ < 6 if a random sample of the test
times of 20 high school seniors has a standard deviation s = 4.51. use a
0.05 level of significance.

Joaquim Rate per hour = 1/7
Josiah Rate per hour = 1/t
1/7 + 1/x = 1/3
(same denominator & simplification) gives: t = 21/4 = 5.25 .
Josiah needs 5.25 hours to clean alone
(I really don't know why the answer is 5.3 . Can you pls check with the teacher?
