The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 10% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. Assuming his suspicion that 10% of his customers buy a magazine is correct, what is the probability that exactly 5 out of the first 13 customers buy a magazine?
Answers
Answer:
0.55% probability that exactly 5 out of the first 13 customers buy a magazine
Step-by-step explanation:
For each customer, there are only two possible outcomes. Either they buy a magazine, or they do not. The probability of a customer buying a magazine is independent of other customers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
10% of his customers buy a magazine
This means that [tex]P = 0.1[/tex]
What is the probability that exactly 5 out of the first 13 customers buy a magazine?
This is P(X = 5) when n = 13. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{13,5}.(0.1)^{5}.(0.9)^{8} = 0.0055[/tex]
0.55% probability that exactly 5 out of the first 13 customers buy a magazine
Answer:
[tex] P(X=5) = (13C5) (0.1)^5 (1-0.1)^{13-5}= 0.00554[/tex]
So then he probability that exactly 5 out of the first 13 customers buy a magazine is 0.0554
Step-by-step explanation:
Let X the random variable of interest "number of customers that buy a magazine", on this case we can model the variable of interest with this distribution:
[tex]X \sim Binom(n=13, p=0.1)[/tex]
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
We want to find this probability:
[tex] P(X=5)[/tex]
And using the probability mass function we got:
[tex] P(X=5) = (13C5) (0.1)^5 (1-0.1)^{13-5}= 0.00554[/tex]
So then he probability that exactly 5 out of the first 13 customers buy a magazine is 0.0554

How many short-sleeved shirts were ordered?
How many long-sleeved shirts were ordered?
Answers
Answer:
150 short-sleeved shirts100 long-sleeved shirtsStep-by-step explanation:
Let S and L represent the numbers of short- and long-sleeved shirts ordered.
The expected earnings were ...
5S +10L = 1750
The number sold was ...
(1/3)S + (1/2)L = 100
We can multiply the first equation by 1/5 and the second equation by 6 to put the equations into standard form:
S +2L = 3502S +3L = 600Subtracting the second equation from twice the first gives ...
2(S +2L) -(2S +3L) = 2(350) -(600)
L = 100 . . . . . . simplify
2S +3(100) = 600
S = 150
150 short-sleeved and 100 long-sleeved shirts were ordered.

right, and drive east for another 24 miles,
At the end of driving, what is your straight
line distance from your starting point?
Answers
Answer:
40 miles
Step-by-step explanation:
In the attached diagram, Point A is the starting point and C is the end point. We want to determine the distance from A to C.
The path driven forms a right triangle in which AC is the hypotenuse.
We therefore use the Pythagorean Theorem to solve for the AC.
Pythagorean Theorem: [tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]
[tex]|AC|^2=32^2+24^2\\|AC|^2=1600\\|AC|=\sqrt{1600}\\ |AC|=40$ miles[/tex]

Answer:

Step-by-step explanation:
Let quarters be 3x and nickels be $x
if Mark had 3 times as many quarters as nickels, and if he had $1.60 in all, than
( 0.25)3x + 0.05x=1.6
0.75x+ 0.05x=1.6
0.8x=1.6
x=1.6/0.8
x=2 nickels
and 3 (2)=6 quarters
Answer:
There are 4 quarters and 12 nickels.
Step-by-step explanation:
A quarter is equal to $0.25.
A nickel is equal to $0.05.
Let the number of nickels be y.
Let the number of quarters be x.
Mark had 3 times as many quarters as nickels. This means that:
y = 3x
3x represents the number of nickels.
We are told that he had $1.60 in all. This means that:
0.25x + 0.05y = 1.60
=> 0.25x + 0.05 * 3x = 1.60
0.25x + 0.15x = 1.60
0.40x = 1.60
=> x = 1.6 / 0.4 = 4
Therefore:
y = 3 * 4 = 12
There are 4 quarters and 12 nickels.

Write y as the sum of a vector in Span {u} and a vector orthogonal to u.
y = z = ___ + ___. (Type an integer or simplified fraction for each matrix element. List the terms in the same order as they appear in the original list.)
Answers
Answer:
Take [tex]b = \frac{3}{10}(6,2)[/tex] as the vector in Span(u) and [tex]w = \frac{4}{5}(-1,3)[/tex] as the orthogonal vector to u
Step-by-step explanation:
Given vectors a,b we can calculate the projection of a onto b by the formula
[tex] \frac{a\cdot b}{b\cdot b}b[/tex]. where [tex]\cdot[/tex] is the dot product of vectors.
For this example, we will take y = [1,3] and u = [6,2].
Let b be the projection of y onto u. That is
[tex] b= \frac{y\cdot u}{u\cdot u}u = \frac{1\cdot 6+ 3\cdot 2}{6\cdot 6+2\cdot 2}(6,2) = \frac{3}{10}(6,2)[/tex]
Now, we want to find an orthogonal vector w such that b+w = y. From this equation, we can find w by taking w = y-b. Then
[tex] w = (1,3)-\frac{3}{10}(6,2) = \frac{4}{5}(-1,3)[/tex]
We must check that w and u are orthogonal. Note that if the vectors a,b are orthogonal, then the vectors a, kb are also orthogonal for every non-zero value of k. So, to check that a,kb are orthogonal, it suffices to check that a,b are orthogonal. We know that two vectors are orthogonal if and only if their dot product is zero. In our case, take the vector (6,2) and (-1,3). Note that
[tex](6,2)\cdot(-1,3) = -6+2\cdot3 = 0[/tex]
So, by the previous analysis, w and u are orthogonal.

C-Spec, Inc., is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of {eq}4 \pm 0.003 {/eq} inches. After a trial run on this machine, C-Spec has determined that the machine has a sample mean of 4.001 inches with a standard deviation of 0.002 inch.
a. Calculate the {eq}C_{pk} {/eq} for this machine
b. Should C-Spec use this machine to produce this part? Why?
Answers
Answer:
Step-by-step explanation:
Given that :
sample mean = 4.001 inches
sample standard deviation = 0.002 inch
a.
[tex]C_{pk} = min [\dfrac{(USL- \bar X)}{(3*std \ dev)} \ ; \ \dfrac{ (\bar X- LSL)}{(3*std \ dev)}][/tex]
specification = [tex]4 \pm 0.003[/tex]
Upper specification limit USL = 4 + 0.003 = 4.003
Lower specification limit LSL = 4 - 0.003 = 3.997
[tex]\dfrac{ (\bar X- LSL)}{(3*std \ dev)} = \dfrac{ (4.001-3.997)}{(3*0.002)}[/tex] [tex]= 0.667[/tex]
[tex]\dfrac{(USL- \bar X)}{(3*std \ dev)} =\dfrac{(4.003-4.001)}{(3*0.002)}[/tex][tex]= 0.333[/tex]
Thus ;
[tex]C_{pk} =[/tex][tex]min (0.333 , 0.667)[/tex] = 0.333
[tex]C_{pk}[/tex] is a measure of closeness to one's target and the consistency around the average performance.
b) No, C - spec should not use this machine to produce this part because [tex]C_{pk}[/tex] < 1.33 which typical means that the part is not fully capable of hitting the target specification on a consistent basis .
Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3
cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?
Answers
Answer:
3.375 bags of soil are needed for Paj to fill the flower pot
Step-by-step explanation:
This question can be solved using a rule of three.
One bag contains 2 + (2/3) = (8/3) cubic inches of soil. How many bags are needed to fill 9 cubic inches of soil?
1 bag - (8/3) cubic inches
x bags - 9 cubic inches
[tex]\frac{8x}{3} = 9[/tex]
[tex]8x = 27[/tex]
[tex]x = \frac{27}{8}[/tex]
[tex]x = 3.375[/tex]
3.375 bags of soil are needed for Paj to fill the flower pot
Paj needs 3.375 bags of soil to fill the bag.
Each bag contains 2²/₃ inch³ of soil and they need to fill up a 9 inch³ pot of soil.
First convert the mixed fraction to an improper one:
2²/₃ = 8/3
The number of bags needed is:
= Volume of pot / Quantity of soil in each bag
= 9 ÷ 8/3
= 9 x 3/8
= 3.375 bags of soil
Paj therefore needs 3.375 bags of soil to fill the pot

As quality control manager at a raisin manufacturing and packaging plant, you want to ensure that all the boxes of raisins you sell are comparable, with 30 raisins in each box (assume the population average number of raisins per box is 30). In the plant, raisins are poured into boxes until the box reaches its sale weight. To determine whether a similar number of raisins are poured into each box, you randomly sample 36 boxes about to leave the plant and count the number of raisins in each. In this sample, you find the mean number of raisins in each box to be 28.05, with a standard deviation of 3.87.
1. Perform a two-tailed, single sample t test (p<.05) to determine whether the average number of raisins per box differs from the expected 30.
2. What type of statistical analysis should be run to address this question?3. What are the assumptions of your chosen statistical test?4. Identify the null and alternative/research hypotheses in both words and symbols.
Answers
Answer:
Step-by-step explanation:
The population average number of raisins per box is 30.
The type of statistical analysis to be run here is the inferential statistical analysis and its assumptions include normality, linearity and equality of variance.
Null hypothesis: Average number of raisins per box is 30: u = 30
Alternative hypothesis: Average number of raisins per box is not 30: u ≠ 30
To perform a two tailed single sample test, we have
z statistic = (the sample mean - hypothesized mean) / (SD/√n)
sample mean = 28.05, SD = 3.87 hypothesized mean = 30 n = 36
Thus, we have 28.05 - 30 / (3.87/√36)
= -1.95 / (3.87/6)
= -1.95 / 0.645
= -3.023
we say this is a left tailed test and use the negative z table
where -3.02 = 0.0013
To determine whether the average number of raisins per box differs from the expected 30.
Using p < 0.05, since the observed value 0.0013 is less than 0.05, we conclude the the average number of raisins per box differs from the expected 30.

Job has to pay $9.00 admission for the skating rink and $2 per to rent rollerblades how many hours can he skate for $19
Answers
Answer:
5 hours
Step-by-step explanation:
Here we can create an equation to solve for the number of hours (x) this man can skate for.
Since he has to pay a $9 flat fee, that will be a constant value or our y-intercept in this case.
Our equation will be y = 2x + 9
Since we know his budget is $19, we can set our equation equal to 19, or replace y in this case.
So now we have 19 = 2x +9
Now we need to subtract 9 from both sides to get 10 = 2x
Then we need to divide both sides by 2 to get 5 = x
So this man can skate for 5 hours considering his budget

c+s+a = 253
5c + 7s + 12a = 1828
c=2a
2a + s + a =253
5*2a + 7s + 12a = 1828
3a + s = 253
22a + 7s = 1828
s = 253 - 3a
22a + 7(253 - 3a) = 1828
22a - 21a + 7*253 = 1828
a = 1828 - 7*253
a = 57
s = 253 - 3a = 253 - 3*57 = 82
s = 82
c=2a=2*57= 114
c=114
