Answer: Suppose that [tex]S_{n}[/tex], [tex]K_{n}[/tex] and [tex]A_{n}[/tex] are all sequences, also suppose that [tex]A_{n}[/tex] ⊂ [tex]K_{n}[/tex] ⊂ [tex]S_{n}[/tex] ∀ [tex]n[/tex] ∈ [tex]Z^{+}[/tex]. This implies that [tex]A_{n}[/tex] ⊂ [tex]S_{n}[/tex] as required.
Step-by-step explanation:
If you suppose that [tex]S_{n}[/tex], [tex]K_{n}[/tex] and [tex]A_{n}[/tex] are all representing three sequences respectively, and you also suppose that [tex]A_{n}[/tex] is a subset (in other words subsequence) of [tex]K_{n}[/tex] and [tex]K_{n}[/tex] is a subset (in other words subsequence) of [tex]S_{n}[/tex], where n takes its values from the set of positive integers. We can safely say that [tex]A_{n}[/tex] is a subsequence of [tex]S_{n}[/tex] and this can demosnstrated mathematically as follows:
Suppose that [tex]S_{n}[/tex], [tex]K_{n}[/tex] and [tex]A_{n}[/tex] are all sequences, also suppose that [tex]A_{n}[/tex] ⊂ [tex]K_{n}[/tex] ⊂ [tex]S_{n}[/tex] ∀ [tex]n[/tex] ∈ [tex]Z^{+}[/tex]. This implies that [tex]A_{n}[/tex] ⊂ [tex]S_{n}[/tex] as required.

Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of x that would allow Pattie's Produce to have a daily revenue of at least $255 from selling the packages of strawberries? A. B. -1.872 – 1.615 + 217.55 > 255 -1.812 + 21.61r + 217.55 > 255 -1.8r2 – 21.611 + 217.55 < 255 C. D. -1.812 + 1.61x + 217.55 < 255
Answer:
A. -1.8x² – 1.61x + 217.55 > 255
Step-by-step explanation:
Since Pattie's Produce charges $2.29 for a package of strawberries and 95 packages can be produced daily. The money gotten daily = $2.29 × 95 packages = $217 Since 20 cent increase leads to 9 less package.
The number of 20-cent increases in the cost of a package of strawberries can be gotten from:
(2.29 + 0.2x)(95 - 9x) > 255
217.55 - 20.61x + 19x - 1.8x² > 255
-1.8x² - 1.61x + 217.55 > 255
Answer:
A. -1.8x² – 1.61x + 217.55 > 255

Complete question :
Find the standard deviation of the following data. Round your answer to one decimal place.
X: 0 1 2 3 4 5
P(X) : 0.2, 0.3, 0.1, 0.1, 0.1, 0.2
Answer:
1.833
Step-by-step explanation:
Given the data :
X: 0 1 2 3 4 5
P(X) : 0.2, 0.3, 0.1, 0.1, 0.1, 0.2
Standard deviation (s) = Sqrt[Σx²*f(x) - E(x)²]
E(x) = (0*0.2) + (1*0.3)+(2*0.1)+(3*0.1) + (4*0.1) + (5 * 0.2) = 2.2
Sqrt[Σx²*f(x) - E(x)²]: [(0^2 * 0.2)+(1^2 * 0.3)+(2^2 * 0.1)+(3^2 * 0.1) + (4^2 * 0.1) + (5^2 * 0.2)] - 2.2²
Sqrt(8.2 - 4.84) = 1.833

Lauren can wash a
car in 20 minutes.
How long will it take,
in hours, for her to
wash 60 cars?
Answer:
The answer is 20 hours
Step-by-step explanation:
20x60=1200
1200÷60=20
=========================================
One way to solve
1 car = 20 minutes
3*(1 car) = 3*(20 minutes) multiply both sides by 3
3 cars = 60 minutes
3 cars = 1 hour
20*(3 cars) = 20*(1 hour) ... multiply both sides by 20
60 cars = 20 hours
-------------------
Another way to solve
(1 car)/(20 minutes) = (60 cars)/(x minutes)
1/20 = 60/x
1*x = 20*60 ... cross multiply
x = 1200 minutes
x = (1200 min)*( (1 hr)/(60 min) )
x = (1200/60) hr
x = 20 hours

A bowl of fruit contains seven pieces of fruit, including two bananas and five apples. Three pieces of fruit are chosen. What is the probability that one banana and two apples are chosen?
Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
A combination refers to the selection of objects such that order does not matter. A permutation refers to the arrangement of objects such that order do matter.
Number of bananas = 2
Number of apples = 5
One banana and two apples are chosen.
So,
probability that one banana and two apples are chosen = [tex]\frac{C(2,1)\,C(5,2)}{C(7,3)}[/tex]
[tex]C(2,1)=\frac{2!}{1!(2-1)!}=2[/tex]
[tex]C(5,2)=\frac{5!}{2!(5-2)!}=\frac{5!}{2!31} =10[/tex]
[tex]C(7,3)=\frac{7!}{3!(7-3)!} =\frac{7!}{3!4!}=35[/tex]
So,
Probability that one banana and two apples are chosen = [tex]\frac{2(10)}{35}=\frac{4}{7}[/tex]

Step-by-step explanation:
To determine whether they have a certain disease, 100 people are to have their blood tested.However, rather than testing each individual separately, it has been decided first to place the peopleinto groups of 10. The blood samples of the 10 people in each group will be pooled and analyzedtogether. If the test is negative, one test will suffice for the 10 people, whereas if the test is positive,each of the 10 people will also be individually tested and, in all, 11 tests will be made on this group.Assume that the probability that a person has the disease is .1 for all people, independently of eachother, and compute the expected number of tests necessary for each group. (Note that we areassuming that the pooled test will be positive if at least one person in the pool has the disease.)
Answer:
The expected number of tests necessary for each group is 7.51.
Step-by-step explanation:
The probability of a person having the disease is, P (X) = 0.10.
Then the probability of a person not having the disease is P (X') = 0.90.
It is provided that if the test is negative, one test will suffice for the 10 people.
Bur if the test is positive, each of the 10 people will also be individually tested and, in all, 11 tests will be made on this group.
Compute the expected number of tests necessary for each group as follows:
Expected number of tests = Negative Result × P (X') + Positive Result × P (X)
[tex]=(1\times (0.90)^{10})+(11\times [1-(0.90)^{10}])\\=0.3486784401+7.1645371589\\=7.513215599\\\approx 7.51[/tex]
Thus, the expected number of tests necessary for each group is 7.51.

Step-by-step explanation:
The SAT is required of most students applying for college admission in the United States. This standardized test has gone through many revisions over the years. In 2005, a new writing section was introduced that includes a direct writing measure in the form of an essay. People argue that female students generally do worse on math tests but better on writing tests. Therefore, the new section may help reduce the usual male lead on the overall average SAT score (The Washington Post, August 30, 2006). Consider the following scores on the writing component of the test of eight male and eight female students.

a. Construct the null and the alternative hypotheses to test if females outscore males on writing tests.
b. Assuming the difference in scores is normally distributed, calculate the value of the test statistic. Do not assume that the population variances are equal.
c. Implement the test at α=0.01 and interpret your results.
Answer:\
a
The null hypothesis is [tex]H_o : \mu_1 - \mu_2 \le 0[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 - \mu_2 > 0[/tex]
b
[tex]t = -0.39[/tex]
c
The conclusion
There is sufficient evidence to conclude that the female outscores the male.
Step-by-step explanation:
From the question we are told that
The sample size for male is [tex]n_1 = 30[/tex]
The sample size for female is [tex]n_2 = 30[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The null hypothesis is [tex]H_o : \mu_1 - \mu_2 \le 0[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 - \mu_2 > 0[/tex]
Generally the sample mean for male is
[tex]\= x_1 = \frac{\sum x_i}{n_1}[/tex]
=> [tex]\= x_1 = \frac{620 + 570 +540 + \cdots + 580 }{30}[/tex]
=> [tex]\= x_1 = 574.33 [/tex]
Generally the standard deviation of male is
[tex]s_1 = \sqrt{\frac{\sum (x_1 - \= x)^2}{n_1} }[/tex]
=> [tex]s_1 = \sqrt{\frac{ (620 - 574.33)^2 + (570 - 574.33)^2 + (540 - 574.33)^2 + \cdots +(580 - 574.33)^2 }{30} }[/tex]
=> [tex]s_1 =206.24 [/tex]
Generally the sample mean for female is
[tex]\= x_2 = \frac{\sum x_i}{n_2}[/tex]
=> [tex]\= x_2 = \frac{660 + 590 +560 + \cdots + 560 }{30}[/tex]
=> [tex]\= x_2 = 593.33 [/tex]
Generally the standard deviation of male is
[tex]s_2 = \sqrt{\frac{\sum (x_1 - \= x)^2}{n_2} }[/tex]
=> [tex]\sigma_1 = \sqrt{\frac{ (660 - 593.33)^2 + (590 - 593.33)^2 + (560 - 593.33 )^2 + \cdots +(560 - 593.33)^2 }{30} }[/tex]
=> [tex]s_2 =169.31 [/tex]
Generally the degree of freedom for unequal variance is mathematically represented as
[tex]df = \frac{[\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2} ]^2}{ \frac{[\frac{s_1^2}{n_1}]^2}{n_1 -1} +\frac{[\frac{s_2^2}{n_2}]^2}{n_2 -1} }[/tex]
=> [tex]df = \frac{[\frac{206.24^2}{30} +\frac{169.31^2}{30} ]^2}{ \frac{\frac{206.24^2}{30}}{30 -1} +\frac{\frac{169.31^2}{30}}{30 -1} }[/tex]
=>[tex]df = 56[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= x _1- \= x_2 }{\sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}} }[/tex]
=> [tex]t = \frac{574.33- 593.33 }{\sqrt{\frac{206.24^2}{30} + \frac{169.31^2}{30}} }[/tex]
=> [tex]t = -0.39[/tex]
From the t distribution table the value of [tex]P(t < -0.39)[/tex] at a degree of freedom of [tex]df = 56[/tex] is
[tex]P(t < -0.39) = 0.3490080[/tex]
Hence the p-value is [tex]p-value = 0.3490080[/tex]
From the values obtained we see that the p-value is >[tex]\alpha[/tex]
Hence we fail to reject the null hypothesis.
The conclusion is
There is sufficient evidence to conclude that the female outscores the male
A grocery store sells bananas for $0.59 per pound. On Wednesdays, the store offers a 10% discount to senior
citizens. Create a function f (x) which models the amount, in dollars, a senior citizen would pay for 2 pounds
of bananas on Wednesday
Answer:
2
Step-by-step explanation:
f(x)= 0.90(0.59*2)
A grocery store sells bananas for $0.59 per pound. On Wednesdays, the store offers a 10% discount to senior citizens. We need to create a function f(x) which models the amount in dollars, a senior citizen would pay for 2 pounds
What is a simple Equation?
A mathematical equation which represents the relationship of two expressions on either side of the sign.
The 10% discount will make it so the senior citizens will pay 90% of the price.
90%=0.90
Also we need to know that 0.59*2 means how much money per pound the bananas cost.
So when you put it together, you should get f(x)=0.90(0.59*2)
The function f (x)=0.90(0.59*2) which models the amount, in dollars, a senior citizen would pay for 2 pounds of bananas on Wednesday
So the required function is f(x)=0.90(0.59*2)
