Vending machines can be adjusted to reject coins above and below certain weights. The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram. If a vending machine is adjusted to reject quarters that weigh more than 5.81 grams and less than 5.53 grams, what percentage of legal quarters will be rejected by the vending machine
Answers
Answer: The percentage of legal quarters will be rejected by the vending machine = 2.275%
Step-by-step explanation:
Given: The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram.
Let x be the weights of legal U.S. quarters .
Required probability: [tex]P(x<5.53)+P(x>5.81)[/tex]
[tex]=P(\dfrac{x-\mu}{\sigma}<\dfrac{5.33-5.67}{0.07})+P(\dfrac{x-\mu}{\sigma}>\dfrac{5.81-5.67}{0.07})\\\\=P(z<-4.857)+P(z>2)\approx0.02275 \ \ \ [By\ P-value\ calculator][/tex]
The percentage of legal quarters will be rejected by the vending machine = 2.275%
Three people take 2 1⁄2( two and a half ) hours to deliver leaflets to 270 houses
Assuming all people deliver leaflets at the same rate, how long will it take five people to deliver leaflets to 450 houses?
Give your answer in hours and minutes
Answers
9514 1404 393
Answer:
2 hours 30 minutes
Step-by-step explanation:
Effort is measured in people-hours per house. Here, the effort to deliver one leaflet is ...
(3 people)(2.5 hours)/(270 houses) = 1/36 people-hours/house
Then the number of hours (h) for 5 people and 450 houses is ...
(5 people)(h hours)/(450 houses) = 1/36 people-hours/house
h = (1/36)(450/5) = 2.5
It will take 2 hours 30 minutes to deliver to 450 houses.
_____
Alternate solution
The time is (assumed) inversely proportional to the number of people, so increasing the number of people from 3 to 5 multiplies the time by 3/5. The time is proportional to the number of houses, so increasing the number of houses from 270 to 450 multiplies the time by 450/270 = 5/3. The time for the second task is (3/5)(5/3) = 1 times the time for the first task.
2 1/2 hours is 2 hours 30 minutes.

A group of people move a large box that weighs 90 Newtons, 10 meters in 20 seconds, how much power was used?
Answers
Answer:
P = 45 W
Step-by-step explanation:
Given that,
The weight of a box, W = 90 N
Distance moved, d = 10 m
Time, t = 20 s
We need to find the amount of power used. The rate of doing work is called power It can be calculated as the formula,
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{90\times 10}{20}\\\\P=45\ W[/tex]
So, 45 W of power was used.

A local baseball team is struggling this season, and many fans of the team believe it may be time to replace the head coach. To estimate support for firing the current head coach, a television news station provides a link on its website where fans of the team can respond to the question: "Do you feel the current head coach should be fired?" After 2,367 votes on the website, 79% of those who responded felt the coach should be fired. Which of these describes the type of bias in this survey and a likely direction of the bias in estimating overall support for firing the coach?
A) This is nonresponse bias. The result overestimates true support for firing the coach.
B) This is nonresponse bias. The result underestimates true support for firing the coach.
C) This is voluntary response bias. The result overestimates true support for firing the coach.
D)This is voluntary response bias. The result underestimates true support for firing the coach.
Answers
Answer:
Option A
Step-by-step explanation:
Here in this case the respondents differ from the non respondents in more than one ways and hence this results to a nonresponse bias due to which there is an extra thumbs up in support of firing the coach thereby leading to an over estimated number.
Hence, option A is correct

20.9m
14.3m
22.7 m
Answers
Answer:
474.43 m²
Step-by-step explanation:
The shape is composed of a rectangle and a parallelogram
Area of the composite shape = area of the rectangle + area of the parallelogram
= Length*Width + base*height
Where,
Length = 20.9 m
Width = 14.3 m
base = 20.9 m
height = 22.7 - 14.3 = 8.4 m
Area = 20.9*14.3 + 20.9*8.4
Area = 298.87 + 175.56
= 474.43 m²
