Step-by-step explanation:
. 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.
solve for X

Answer:
x=19.55
hope it help you..
Answer:
19.55
Step-by-step explanation:
x/8.5 = 2.3
x = 8.5 × 2.3
x = 85 × ⅒ × 23 × ⅒
x = 85 × 23 × ⅒ × ⅒
x = 1955 × 1/100
x = 1955/100
x = 19.55
In a deck of 52 cards there are 2 jokers and 4 each of the number cards 1-10. The probability of picking a joker is 2 out of 52 or 2/52. Write as a fraction, the probability of drawing a number 7 card.
Answer:
1/13
Step-by-step explanation:
The number 7 cards= 4 of them
Total number of cards= 52
4/52 are 7's
Simplify 4/52>>>>2/26>>>>1/13

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

The measure of an angle is 37.1º, What is the measure of its complementary angle?
Answer:
52.9º
Step-by-step explanation:
complementary is when the sum of two angles is 90 degrees
to solve, simply take 37.1 and subtract it from 90:
⇒ 90 - 37.1
⇒ 52.9
4(3x - 2 + 1 ) + 23 + 2x
Step-by-step explanation:
first you distribute
12x - 8 + 4 +23 +2x
than you add the numbers without the variable so...
-8+4+23= 19
Add the # with variables
12x+2x= 14×
then you get
14x=19
divide by 14 in each side
x=1.4

Answer:
254.47 inches squared
Step-by-step explanation:
Area of a circle is
[tex]\pi {r}^{2} [/tex]
so to find the radius we half the diameter( which here is 18 inches) which equals to 9
we replace r to 9 because that's the radius
[tex]\pi \times {9}^{2} [/tex]
which is 254.47 inches squared

opposite sides of a parallelogram are congruent, if that is a parallelogram
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.

A poll conducted in 2013 found that 55% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). The standard error for this estimate was 2.2%, and a normal distribution may be used to model the sample proportion. Construct a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter, and interpret the confidence interval in context. (please round all percentages to 2 decimal places)
Answer:
The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is between 49.34% and 60.66%, which means that we are 99% sure that the true percentage of US adult Twitter users who get some news is in this interval.
Step-by-step explanation:
Confidence interval:
A confidence interval has the following format:
[tex]M \pm zs[/tex]
In which M is the sample mean, z is related to the confidence level and s is the standard error.
55% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). The standard error for this estimate was 2.2%.
This means that [tex]M = 55, s = 2.2[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
Lower bound of the interval:
[tex]M - zs = 55 - 2.575*2.2 = 49.34[/tex]
Upper bound:
[tex]M + zs = 55 + 2.575*2.2 = 60.66[/tex]
The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is between 49.34% and 60.66%, which means that we are 99% sure that the true percentage of US adult Twitter users who get some news is in this interval.
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
So about 942 , answer 3 looks right :) sorry I got to your question late, send me a note , when you have a question, so I'll see :)
