Answer:
P≈14.14
Step-by-step explanation:
Diagonal
5
Using the formulas
P=4a
d=2a
Solving forP
P=22d=2·2·5≈14.14214
Answer:
Option a) A 95% confidence interval for the mean diameter of the 120 bearings in the sample is
.
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 120
Sample mean = 10 mm
Standard Deviation = 0.24 mm
Formula:



Hence, the correct interpretation for the confidence interval is given by option a).
A 95% confidence interval for the mean diameter of the 120 bearings in the sample is
.
We have to consider the factor of sampling of 120 ball bearings from a population of 10,000 ball bearings.
Answer:
P(x) = 0.50x - 5
Step-by-step explanation:
x = number of glasses sold
She charges $0.50 per glass, so her revenue is
R(x) = 0.50x
which is the amount of money she brings in
Her cost function is
C(x) = 5
assuming she only spends that $5.00 on the supplies mentioned.
The profit P(x) is the difference of revenue and cost
Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = 0.50x - 5
