By making the surface rougher and to increase the force pushing the surfaces together.
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

Step-by-step explanation:
Quotient of s and r is s/r
s/r to the 3rd power = (s/r)^3
Taking the test rn, it’s 190 square inches.
