A manufacturer of computer printers purchases plastic ink cartridges from a vendor. When a large ship- ment is received, a random sample of 200 cartridges is se- lected, and each cartridge is inspected. If the sample pro- portion of defective cartridges is more than .02, the entire shipment is returned to the vendor.
a. What is the approximate probability that a shipment will be returned if the true proportion of defective car- tridges in the shipment is .05?
b. What is the approximate probability that a shipment will not be returned if the true proportion of defective car- tridges in the shipment is .10?
Answer:
a. 0.9744
b = 0.00008 (approximately 0)
Step-by-step explanation:
We have the sampling distribution following a normal distribution.
1
the proportion, p^ is 0.05, n = 200
Standard deviation = √p^(1-p^)/n
= √0.05(1-0.05)/200
= √0.0475/200
= √0.0002375
= 0.0154
The probability (p>0.02)
= p(z>0.02-0.05/0.0154)
= P(z>-1.95)
= P(z<1.95)
When we use the standard normal table = 0.9744
So, 0.9744 is the approximate probability that a shipment will be returned if the true proportion of defective car- tridges in the shipment is 0.05
b. P^ = 0.10( true population of defective cartridges = 0.10)
= √0.10(1-0.10)/200
= 0.0212
Probability it will not be returned
= P(p<=0.02)
= P(z<=0.02-0.10/0.0212)
= P(Z<= -3.77)
Using the standard normal table
1-p(z<3.77)
= 1 - 0.99992
= 0.00008
This is approximately 0
Thisis the approximate probability that a shipment will not be returned if the true proportion of defective car- tridges in the shipment is .10
Given that f(x) = 2x+4 and h(x)= x3, find (h of)(1).
Answer:
Solution,
Given,
f(x) = 2x + 4
h(x) = [tex]x^{3}[/tex]
Now,
hof(x) = h{f(x)} = h (2x + 4) = [tex](2x+4)^{3}[/tex]
Put x = 1,
hof(1) = [tex][2(1)+4]^{3}[/tex] = 216

Olivia needs 545454 licks for every 333 lollipops she eats.
Answer:
54 lick per 3 lollipops is a unit rate of 18 licks per lollipop.
36 is 2 times 18, so it needs 2 times as many licks as 18 lollipops.
36 2
I assume the last line is 5 lollipops.
If 1 lollipop takes 18 licks, then 5 lollipops take 5 * 18 licks.
5 * 18 = 90
90 5
Answer: i think 2 because 90 divided by 5 is 18 and 54 divided by 3 is 18 so

A group of band instructors answered a survey about hours of rehearsal per week and number of competitions won. The graph shows the results of this survey.
Based on these results, if a band practices 5 hours per week next season, which is the best estimate of the number of competitions the band can expect to win?
A.
36
B.
31
C.
27
D.
24
Answer: B. 31
Step-by-step explanation:
This linear regression was constructed by relating the hours practiced per week and the number of competitions won.
Going by this graph, the number of competitions they can expect to win at 5 practices a week is 31.
This is derived by looking for the point where 5 competitions on the x-axis intersects with the line. This point is at 31 competitions on the y axis which would make it the answer.

Writing equations of lines
Answer:
Step-by-step explanation:
You can see that (0,6) and (1,1) are points on the line.
Use their coordinates to calculate the slope.
slope = (6-1)/(0-1) = 5/(-1) = -5
You can also see that the y-intercept is 6.
Slope-intercept equation of the line: y = -5x+6
16 Compare Dawn earned $97.50 for 10 hours of work. Amy earned $120 for 12 hours
of work. How much did each person earn per hour? How can you use this information
to compare their earnings?
Curriculum Associates, Copy
16
Lesson 2 Understand Unit Rate
Answer:
Dawn earns $9.75 per hour while Amy earns $10 per hour.
This information is important in comparing who is actually earning more than the other. Amy is earning $0.25 more than Dawn is earning. Thus, working for an extra 2 hours than Dawn made her earn $22.5 more than Dawn earned in a week.
Step-by-step explanation:
You can get the hourly work rate of Dawn and Amy by dividing their total earnings to the number of hours they worked.
Dawn = $97.50 ÷ 10 = $9.75Amy = $120 ÷ 12 = $10You can get the difference in hourly rate by subtracting Dawn's earning from Amy's earning.
$10 - $9.75 = $0.25You can also get the difference in their weekly earnings by subtracting Dawn's total weekly earning from Amy's total weekly earning.
$120 - $97.50 = $22.5Suppose that a bike rents for $4 plus $2.50 per hour. Write an equation in slope-intercept form that models this situation.

Ivanah answered 96% of the test questions correctly. There are 50 questions on the test. How many questions did Ivanah answer correctly?
Answer:
48
Step-by-step explanation:
50*96%=48
Answer: 48 questions
Step-by-step explanation:
The way you were told how to do this could be different but this is how I learned-
96%=ninety six hundredths, also written as (96/100). That represents the part out of the whole ( you got 96 out of 100). That fraction is equal to (x/50), where x= questions answered correctly. To find x, multiply 50 by 0.96 (because 0.96= 96/100)

All trucks traveling on Interstate 40 between Albuquerque and Amarillo are required to stop at a weigh station. Trucks arrive at the weigh station at a rate of 0.42 trucks/min, and the station can weigh, on the average, 0.46 trucks/min. Determine the following:
a. Average number of trucks waiting in the queue, Lq
b. Average waiting time in the queue for each truck, Wq
c. Average time spent in the system by each truck, W
d. Probability that arriving truck has to wait for service, PW
e. Probability that one truck is waiting in the queue and one truck is being served, P2
f. What is the probability that more than two trucks are waiting in the queue (i.e. more than three in the system)?
Answer:
9.587 ; 22.83 ; 25 minutes
Step-by-step explanation:
Given that:
Arrival rate (λ) = 0.42 trucks/ min
Service rate (μ) = 0.46 trucks / min
Trucks arrive at the weigh station at a rate of 0.42 trucks/min, and the station can weigh, on the average, 0.46 trucks/min. Determine the following:
a. Average number of trucks waiting in the queue, Lq
Lq = λ² / μ(μ - λ)
Lq = 0.42² / 0.46(0.46 - 0.42)
Lq = 0.1764 / 0.0184
= 9.5869565
= 9.587
b. Average waiting time in the queue for each truck, Wq
Wq = λ / μ(μ - λ)
Wq = 0.42 / 0.46(0.46 - 0.42) = 22.83 minutes
c. Average time spent in the system by each truck, W
W = 1 / (μ - λ)
W = 1 / (0.46 - 0.42)
W = 1 / 0.04
W = 25 minutes
