where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
G(–2, 6) and H(5, –3)
The slope is
m = -3 - 6 / 5 -- 2 = - 9 /7

<h3>Total approximately 16 boxes of flooring will be needed in Stanley's living room. </h3>
Step-by-step explanation:
Here the given question is <u>incomplete</u>.
Stanley is having wood flooring installed in his living room. The installer has used 10 1/2 boxes of flooring on 2/3 of the room. How many total boxes of flooring will be needed for Stanley's living room?
The number of boxes used in the two third of room = boxes
So, room = 10. 5 boxes

Answer:
0.9792
Step-by-step explanation:
Data provided in the question:
Average gross sales = $1,240
Standard deviation = $180
sample size = 40
Now,
standard deviation of sample average
=
=
= 28.46
Now,
z value for 1200 = = -1.4,
and,
p value for (z = -1.4) = 0.0808
therefore,
P(average < $1200) = 0.0808
Thus,
probability that the average over the next 40 weekdays will exceed $1,200
= 1 - 0.808
= 0.9792
