. The average life of a certain type of small motor is 10 years with a standard deviation of 2 years. The manufacturer replaces free all motors that fail while under guarantee. If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer
Answer:
She should offer a guarantee of 13.76 years.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The average life of a certain type of small motor is 10 years with a standard deviation of 2 years.
This means that [tex]\mu = 10, \sigma = 2[/tex]
If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?
She should offer the 100 - 3 = 97th percentile as a guarantee, so X when Z has a pvalue of 0.97, that is, X when Z = 1.88.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.88 = \frac{X - 10}{2}[/tex]
[tex]X - 10 = 2*1.88[/tex]
[tex]X = 13.76[/tex]
She should offer a guarantee of 13.76 years.

Four people applied for a job as an assistant manager at a store. Only two of these people will be hired.
Answer:
50% of the applicants will be hired.
Step-by-step explanation:
Given that four people applied for a job as an assistant manager at a store, but only two of these people will be hired, the following calculation must be performed to determine the percentage of people who will enter the job:
4 - 2 = 2
4 = 100
2 = X
2 x 100/4 = X
200/4 = X
50 = X
Thus, 50% of the applicants will enter the job.

a snowplow driver cleared 20 streets in 55 minutes. How fast did he clear each street.
Answer:
2.75 minutes
Step-by-step
divide 55 by 20
Answer:
2.75 minutes/2 minutes and 45 seconds
Step-by-step explanation:
Divide: 55 divided by 20=2.75
2.75 minutes= 2 minutes and 45 seconds
The reason why you divide 55 divided by 20 is because you are trying to find how long it took you to clear 1 street.
And there are 20 streets and each street took you 2 minutes and 45 minutes to complete 1 street.
Hope this helped!! :)

Assume that the average life of a refrigerator is 14 years, with the standard deviation given in part (a) before it breaks. Suppose that a company guarantees refrigerators and will replace a refrigerator that breaks while under guarantee with a new one. However, the company does not want to replace more than 6% of the refrigerators under guarantee. For how long should the guarantee be made (rounded to the nearest tenth of a year)
Answer:
The guarantee should be made of [tex]X = 1.555 + 14\sigma[/tex] years, in which [tex]\sigma[/tex] is the standard deviation given in part (a).
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Assume that the average life of a refrigerator is 14 years
This means that [tex]\mu = 14[/tex]
The standard deviation given in part (a) before it breaks.
This will be the value of [tex]\sigma[/tex]
However, the company does not want to replace more than 6% of the refrigerators under guarantee. For how long should the guarantee be made?
We need to find the 100 - 6 = 94th percentile, which is X when Z has a pvalue of 0.94. So X when Z = 1.555. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.555 = \frac{X - 14}{\sigma}[/tex]
[tex]X = 1.555 + 14\sigma[/tex]
The guarantee should be made of [tex]X = 1.555 + 14\sigma[/tex] years, in which [tex]\sigma[/tex] is the standard deviation given in part (a).

Monica has a cylindrical container full of marbles. The container is shown below.
10 cm
The height of the container is approximately 12 centimeters. Which is closest to
the volume of Monica's container, in cubic centimeters?
Answer:
Area of a circle is pi * [tex]r^{2}[/tex]
then multiply that by the height
Step-by-step explanation:
diameter = 10
radius is diameter / 2
r = 10/2 = 5
A = pi * [tex]5^{2}[/tex]
A = 78.5398
height * A = volume
12 * 78.5398 = 942.477

Answer:
kk so imma help you with this because this is like reealllyy easy soo basically all you have to do is use the multichoice and multiply is with the number example here is 2 then subtract/multiply/add/divide with the other number which is for this problem is 2. And right now our main goal is for it to equal 22 because both sides are equal. So if we multiplied 2 with 7 it would equal 14 and 14-2=12 which not be true. So you would have to the same thing for every one of the choices till it fits. And for this problem it would be 12 because 12x2=24 and 24-2=22. lol i hope you understand this whole thing annywwaaayyss hope this helped imma go finish my test now.
-7x-4y=18
y=-5x-24
solve for x and y (show work)
Answer:
ima answer it but first how do i show the work
Step-by-step explanation:
Answer:
(-6, 6)
x=-6, y=6
Step-by-step explanation:
The easiest way to solve for this is by substitution. This means substituting y with -5x-24 in the first equation. It gives you the same variables and is easy to work with.
1. Set up your equation: -7x-4(-5x-24)=18
2. Use the distribution property: -7x+20x+96=18
3. Add like terms: 13x+96=18
4. Subtract 96 from both sides: 13x=-78
5. Divide by 13 to get x alone: x=-6
Now that we have x, we can find y much easier by plugging in -6 for x.
1. Set up your equation: -5(-6)-24=y
2. Multiply: 30-24=y
3. Subtract: 6=y
Check your answers!
-7(-6)-4(6)=18
-5(-6)-24=6
There you go! Hope this helped :)
1. The snow pack on Mt. Hood in the Oregon Cascades was 150 inches on
January 15th. Based on data taken in previous years, the snow pack decreases
about 11 inches a week after January 15th. What would be the rate of change?
Answer:
The rate of change is 10%
Step-by-step explanation:
The computation of the rate of change is as follows:
Given that as on Jan 15, the snow pack is 150 inches
And, the last year, it would decrease by 11 inches a week after jan 15
So, the rate of change is
= 15 ÷ 150
= 10%

13. You are buying plants and soil for your garden. The soil costs $4.00 per bag and the plants cost $10.00 each. You want to buy at least 5 plants and can spend no more than $100.00 total
Answer:
Part a) The system of linear inequalities is
y\geq 5y≥5
4x+10y\leq 1004x+10y≤100
Part b) The graph in the attached figure
Part c) A solution could be (5,7) (see the explanation)
Step-by-step explanation:
The complete question is
You are buying plants and soil for your garden. The soil cost 4.00 dollars per bag and the plants cost 10.00 each. You want to buy at least 5 plants and can spend no more than10.00each.Youwanttobuyatleast5plantsandcanspendnomorethan100
a) write a system of linear inequalities to model the situation
b) Graph the system of linear inequalities
c) Identify and interpret a solution to the system
Part a) write a system of linear inequalities to model the situation
Let
x -----> the number of bags of soil
y ----> number of plants
we know that
The word "at least" means "greater than or equal"
y\geq 5y≥5 ----> inequality A
The word "no more" means "less than or equal"
4x+10y\leq 1004x+10y≤100 ----> inequality B
Part b) Graph the system of linear inequalities
we have
y\geq 5y≥5 ----> inequality A
4x+10y\leq 1004x+10y≤100 ----> inequality B
using a graphing tool
the solution is the triangular shaded area
see the attached figure
Part c) Identify and interpret a solution to the system
we know that
If a ordered pair is a solution to the system, then the ordered pair must lie on the shaded area of the solution
i take the point (5,7)
the point (5,7) lie on the shaded area of the solution
so
is a solution of the system
That means ----> You are buying 5 bags of soil and 7 plants for your garden
Verify the solution
Remember
If a ordered pair is a solution to the system, then the ordered pair must satisfy both inequalities
Verify inequality A
7\geq 57≥5 ----> is true
so
The ordered pair (5,7) satisfy inequality A
Verify inequality B
4(5)+10(7)\leq 1004(5)+10(7)≤100
90\leq 10090≤100 ---> is true
so
The ordered pair (5,7) satisfy inequality B
therefore
The ordered pair (5,7) is a solution to the system

Answer:
A bit of a doosy, but bare with me: f*g*h(x) = [tex]x^2+54x-12x\sqrt{x} -108\sqrt{x} +90[/tex]
Step-by-step explanation:
So explaining this is a bit awkward as well, but I can try...So
Starting from g(x) working that backwards into f(x), so...
g(x) = [tex]x-3[/tex]
f(x) = [tex](x^4+9)[/tex]
Take your g(x) and plug it into your f(x) into every x you see
f(g(x)) = [tex](x-3)^4+9[/tex] ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...
Now you still have one more step which you still need to include h(x), so
Remember h(x) = [tex]\sqrt{x}[/tex]
Now plug in your h(x) into every x you see from f(g(x)) and it should look like...
[tex](\sqrt{x} -3)^4 + 9[/tex]
