If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimeters?
Complete Question
Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 143 millimetres, and a standard deviation of 5. If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimetres? Round your answer to four decimal places.
Answer:
The probability is [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 47
The mean diameter is [tex]\mu = 143[/tex]
The standard deviation is [tex]\sigma = 5[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{5 }{\sqrt{47} }[/tex]
=> [tex]\sigma_{x} = 0.7293[/tex]
Generally the probability that the sample mean will differ from the population mean by more than 0.2 milli meters is mathematically represented as
[tex]P(|\= x - \mu | \ge 0.2 ) = P(\frac{|\= x - \mu|}{\sigma_{x}} \ge \frac{0.2}{0.7293} )[/tex]
[tex]\frac{|\= x - \mu | -\mu}{\sigma } = |Z| (The \ standardized \ value\ of \ {|\= x - \mu | )[/tex]
=> [tex]P(|\= x - \mu | \ge 0.2 ) = P(|Z| \ge 0.2742 )[/tex]
=> [tex]P(|\= x - \mu | \ge 0.2 ) = P(Z < - 2742) + P(Z > 0.2742)[/tex]
From the z table the area under the normal curve to the left corresponding to -2.742 is
[tex]P(Z < -0.2742) =0.39197[/tex]
From the z table the area under the normal curve to the right corresponding to 2.742 is
P(Z > 0.2742) = 0.39197
So
[tex]P(|\= x - \mu | \ge 0.2 ) = 0.39197 + 0.39197[/tex]
[tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]

which two ratios form a proportion
A 1:2 and 4:2
b 1:2 6:3
c2:1 2:4
d 2:1 and 6 :3
Answer:c
Step-by-step explanation:
Did the test
Answer:
D. 2:1 & 6:3
Step-by-step explanation:
Proportion means equal so we need to see which ratios are equal.
To do that we need to make one fo the numbers in the ratio equal the corresponding number in the other ratio, then see if the other matches.
A:
1:2 & 4:2
The second number is already the same but the first isn't, therefore it is not proportional.
B:
1:2 & 6:3
To get 1 to equal 6 we must multiply it by 6, and what you do to one side you must do to the other so we have to multiply 2 by 6 as well
6:12 & 6:3
The first numbers are the same but the second isn't, therefore it is not proportional.
C:
2:1 & 2:4
The first numbers are the same but the second isn't, therefore it is not proportional
D:
2:1 & 6:3
to get 2 to equal 6 we need to multiply it by 3, which means we have to multiu 1 by 3 too
6:3 & 6:3
These are equal so this is proportional.

The elevation of a mountain is 27,370 feet. Due to erosion, this mountain is reduced by 0.2% each year. In how many years will the elevation be 26,986.82 feet?
Answer:
7 years
Step-by-step explanation:
27370 - 26986.82 = 383.18ft
0.2% = 0.2/100 = 0.002
27370*0.002 = 54.74
each year the montain reduce your elevation
54.74ft
then:
383.18/54.74 = 7

frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another. How many seeds is frank going to plant?
Answer:
5b + 2
Step-by-step explanation:
Frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another.
We need to find how many seeds is frank going to plant.
It is equal to the sum of vegetable seeds in one garden and the vegetable seeds in another.
Sum = b + 4b + 2
Sum = 5b + 2
So, there are "5b + 2" seeds frank going to plant.

casey wants to buy a gym memebership. One gym has a $80 joining fee and cost $35 per month. Another gym has no joining fee and costs 75$ per month. When would casey pay the same amount to be a member of either gym? how much would she pay?
Answer:
they cost the same after 2 months
Step-by-step explanation:
Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:
35x + 80 = 75x (the 1st gym with a joining fee $80 and 35 monthly equals $75 monthly)
Subtract 35x from both sides:
35x - 35x + 80 = 75x - 35x
80 = 40x
Divide by 40:
80 / 40 = 40x / 40
2 = x
So they cost the same after 2 months
35 * 2 + 80 = 75 * 2
150 = 150
And you'll be spending $150 in total.
A boy wants to jump onto a carousel that is spinning at a rate of 14 revolutions per minute. If the carousel is 23 feet in diamter, how fast must the boy run to match the speed of the carousel and jump on?A) 2.68 feet per second.B) 1,011.59 feet per second.C) 33.72 feet per second.D) 16.86 feet per second.
Answer:
16.86 ft/s
Step-by-step explanation:
Given that
Speed of the carousel, s = 14 rpm
Distance from the carousel, d = 23 ft
To start with, we convert the given speed to revolution per second, so that
s = 14/60 rev/sec
To find the needed speed, we use the formula
v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD
v = πnD, and we use this to find our needed velocity
v = 3.142 * 14/60 * 23
v = 72.266 * 14/60
v = 16.86 ft/s
Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it
