Answer 1

Answer:

b. Discrete quantitative

Step-by-step explanation:

Hope that helps

Answer 2

The type of data is Discrete data.

What is Discrete data?

Discrete data is information that can only take certain values. These values don't have to be whole numbers (a child might have a shoe size of 3.5 or a company may make a profit of £3456.25 for example) but they are fixed values – a child cannot have a shoe size of 3.72!

When values in a data set are countable and can only take certain values, it is called discrete data.

For example, number of students in a class, number of players required in a team, Number of players participated in a race, etc

We can easily count the variables in a discrete data.

Hence, type of data is Discrete data.

Answers

Answer:

QUESTION 2 -> Correct option: A.

QUESTION 3 -> Correct option: C.

Step-by-step explanation:

QUESTION 2

To find the amount of tax we just need to multiply the tax rate by the original price of the product:

[tex]Tax = 29\% * 53.93[/tex]

[tex]Tax = 0.29 * 53.93[/tex]

[tex]Tax =\$15.64[/tex]

Then, to find the total selling price, we need to sum the original price to the tax value:

[tex]Total = tax + price[/tex]

[tex]Total = 15.64 + 53.93[/tex]

[tex]Total = \$69.57[/tex]

Correct option: A.

QUESTION 3

US consumers are increasingly using debit cards as a substitute for cash and checks. From a sample of 100 consumers, the average amount annually spent on debit cards is $7,790. Assume that this average was based on a sample of 100 consumers and that the population standard deviation is $500.
A. At 99% confidence, what is the margin of error?
B. Construct the 99% confidence interval for the population mean amount spent annually on a debit card.

Answers

Answer:

A. Margin of error = 128.79

B. The 99% confidence interval for the population mean is (7661.21, 7918.79).

Step-by-step explanation:

We have to calculate a 99% confidence interval for the mean.

The population standard deviation is know and is σ=500.

The sample mean is M=7790.

The sample size is N=100.

As σ is known, the standard error of the mean (σM) is calculated as:

[tex]\sigma_M=\dfrac{\sigma}{\sqrt{N}}=\dfrac{500}{\sqrt{100}}=\dfrac{500}{10}=50[/tex]

The z-value for a 99% confidence interval is z=2.576.

The margin of error (MOE) can be calculated as:

[tex]MOE=z\cdot \sigma_M=2.576 \cdot 50=128.79[/tex]

Then, the lower and upper bounds of the confidence interval are:

[tex]LL=M-t \cdot s_M = 7790-128.79=7661.21\\\\UL=M+t \cdot s_M = 7790+128.79=7918.79[/tex]

The 99% confidence interval for the population mean is (7661.21, 7918.79).

Prove the identity cos x/1 - sin x = sec x + tan x

Answers

Answer:

Proved

Step-by-step explanation:

Given

Prove that

[tex]\frac{cos x}{1 - sin x} = sec x + tan x[/tex]

[tex]\frac{cos x}{1 - sin x}[/tex]

Multiply the numerator and denominator by 1 + sinx

[tex]\frac{cos x}{1 - sin x} * \frac{1 + sin x}{1 + sin x}[/tex]

Combine both fractions to form 1

[tex]\frac{cos x (1 + sin x)}{(1 - sin x)(1 + sin x)}[/tex]

Expand the denominator using difference of two squares;

[tex]i.e.\ (a - b)(a + b) = a^2 - b^2[/tex]

The expression becomes

[tex]\frac{cos x (1 + sin x)}{(1^2 - sin^2 x)}[/tex]

[tex]\frac{cos x (1 + sin x)}{(1 - sin^2 x)}[/tex]

From trigonometry; [tex]1 - sin^2x = cos^2x[/tex]

The expression becomes

[tex]\frac{cos x (1 + sin x)}{(cos^2 x)}[/tex]

Divide the numerator and the denominator by cos x

[tex]\frac{(1 + sin x)}{(cos x)}[/tex]

Split fraction

[tex]\frac{1}{cos x} + \frac{sin x}{cos x}[/tex]

From trigonometry; [tex]\frac{1}{cos x} = sec x \ and\ \frac{sin\ x}{cos\ x} = tan\ x[/tex]

So;

Answers

Answer:

Mean increase or decrease (same quantity) according to the quantity of the increment or reduction

As all elements were equally affected the standard deviation will remain the same

Step-by-step explanation:

For the original set of salaries: ( In thousands of $ )

51, 53, 48, 62, 34, 34, 51, 53, 48, 30, 62, 51, 46

Mean = μ₀ = 47,92

Standard deviation  =  σ = 9,56

If we raise all salaries in the same amount  ( 5 000 $ ), the nw set becomes

56,58,53,67,39,39,56,58,53,35,67,56,51

Mean   =  μ₀´  = 52,92

Standard deviation  =  σ´ = 9,56

And if we reduce salaries in the same quantity ( 2000 $ ) the set is

49,51,46,60,32,32,49,51,46,28,60,49,44

Mean μ₀´´ = 45,92

Standard deviation  σ´´ = 9,56

What we observe

1.-The uniform increase of salaries, increase the mean in the same amount

2.-The uniform reduction of salaries, reduce the mean in the same quantity

3.-The standard deviation in all the sets remains the same.

We can describe the situation as a translation of the set along x-axis (salaries). If we normalized the three curves we will get a taller curve (in the first case) and a smaller one in the second, but the  data spread around the mean will be the same

Any uniform change in the data will directly affect the mean value

Uniform changes in values in data set will keep standard deviation constant

g On a certain daily flight, Air Northeast has a policy of booking as many as 22 people on an airplane that can seat only 19. Past studies have revealed that only 89% of the booked passengers actually arrive for the flight. If the airline books 22 people on a flight, find the probability that there will not be enough seats available for all booked passengers. Show sufficient work to justify answer

Answers

Answer:

55.82% probability that there will not be enough seats available for all booked passengers.

Step-by-step explanation:

For each booked passenger, there are only two possible outcomes. Either they arrive for the flight, or they do not arrive. The probability of a booked passenger arriving is independent of other booked passengers. So we used 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.

The airline books 22 people on a flight

This means that [tex]n = 22[/tex]

Past studies have revealed that only 89% of the booked passengers actually arrive for the flight.

This means that [tex]p = 0.89[/tex]

Find the probability that there will not be enough seats available for all booked passengers.

The airplane seats 19, so this is the probability of more than 19 passengers arriving.

[tex]P(X > 19) = P(X = 20) + P(X = 21) + P(X = 22)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 20) = C_{22,20}.(0.89)^{20}.(0.11)^{2} = 0.2718[/tex]

[tex]P(X = 21) = C_{22,21}.(0.89)^{21}.(0.11)^{1} = 0.2094[/tex]

[tex]P(X = 22) = C_{22,22}.(0.89)^{22}.(0.11)^{0} = 0.0770[/tex]

[tex]P(X > 19) = P(X = 20) + P(X = 21) + P(X = 22) = 0.2718 + 0.2094 + 0.0770 = 0.5582[/tex]

55.82% probability that there will not be enough seats available for all booked passengers.

d. $350,000

e. $3,150,000

f. $2,675,000

g. Accounts payable and accruals

Step-by-step explanation:

a. Total debt is long term debt $825,000

b. The amount of liability apearing on balance sheet is $1,175,000 ($825,000 + $350,000)

The amount of equity appearing in balance sheet is $2,000,000

c. Current Assets balance on the balance sheet is $750,000 ($3.5m - $2.75m)

the difference of total assets and net plant equipment.

d. Current liabilities to be reported on the balance sheet is $350,000 and the amount of accounts payable and other payable.

e. Net working capital is calculated by taking total assets and then deducting current liabilities from it. $3,150,000 ($3500,000 - $350,000)

f. Operating working capital is calculated by subtracting total liablities from total assets. $2,675,000 ($3,500,000 - $825,000)

g. The amount of accounts payable and accruals is not provided in the question the amount will be reported in the balance sheet.

Would you need to use the chain rule to find the derivative of this function?

Answers

Answer:

TRUE. We need to use the chain rule to find the derivative of the given function.

Step-by-step explanation:

Chain rule to find the derivative,

We have to find the derivative of F(x)

If F(x) = f[g(x)]

Then F'(x) = f'[g(x)].g'(x)

Given function is,

y = [tex]\sqrt{2x+3}[/tex]

Here g(x) = (2x + 3)

and f[g(x)] = [tex]\sqrt{2x+3}[/tex]

[tex]\frac{dy}{dx}=\frac{d}{dx}(\sqrt{2x+3}).\frac{d}{dx} (2x+3)[/tex]

y' = [tex]\frac{1}{2}(2x+3)^{(1-\frac{1}{2})}.(2)[/tex]

   = [tex](2x+3)^{-\frac{1}{2}}[/tex]

y' = [tex]\frac{1}{\sqrt{2x+3}}[/tex]

Therefore, it's true that we need to use the chain rule to find the derivative of the given function.

7.1 A player throws a fair die and simultaneously flips a fair coin. If the coin lands heads, then she wins twice, and if tails, then she wins one-half of the value that appears on the die. Determine her expected winnings.

Answers

Answer:

1.875

Step-by-step explanation:

To find the expected winnings, we need to find the probability of all cases possible, multiply each case by the value of the case, and sum all these products.

In the die, we have 6 possible values, each one with a probability of 1/6, and the value of each output is half the value in the die, so we have:

[tex]E_1 = \frac{1}{6}\frac{1}{2} + \frac{1}{6}\frac{2}{2} +\frac{1}{6}\frac{3}{2} +\frac{1}{6}\frac{4}{2} +\frac{1}{6}\frac{5}{2} +\frac{1}{6}\frac{6}{2}[/tex]

[tex]E_1 = \frac{1}{12}(1+2+3+4+5+6)[/tex]

[tex]E_1 = \frac{21}{12} = \frac{7}{4}[/tex]

Now, analyzing the coin, we have heads or tails, each one with 1/2 probability. The value of the heads is 2 wins, and the value of the tails is the expected value of the die we calculated above, so we have:

[tex]E_2 = \frac{1}{2}2 + \frac{1}{2}E_1[/tex]

[tex]E_2 = 1 + \frac{1}{2}\frac{7}{4}[/tex]

[tex]E_2 = 1 + \frac{7}{8}[/tex]

[tex]E_2 = \frac{15}{8} = 1.875[/tex]

A research group wants to know if the online platform to play Settlers of Catan is being accessed more after the stay at home order than before it. The mean for number of games started per minute before the stay at home order was 1000. The researchers hypothesize that after the stay at home order, the online platform was accessed more so than before the stay at home order. They set alpha = .05 The mean for number of games started per minute after the stay at home order, was 1378 with a standard deviation of 489. The sample size was 108,000.
a. Given this conclusion, what can you say about the p value of this test statistic?
b. Please calculate the effect size. Is it small, medium, or large?

Answers

Answer:

a) The P-value is 0.

At a significance level of 0.05, there is enough evidence to support the claim that the online platform was accessed significantly more so than before the stay at home order.

b) Effect size d = 0.77

Medium.

Step-by-step explanation:

This is a hypothesis test for the population mean.

The claim is that the online platform was accessed significantly more so than before the stay at home order.

Then, the null and alternative hypothesis are:

[tex]H_0: \mu=1000\\\\H_a:\mu> 1000[/tex]

The significance level is 0.05.

The sample has a size n=108000.

The sample mean is M=1378.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=489.

The estimated standard error of the mean is computed using the formula:

s_M=\dfrac{s}{\sqrt{n}}=\dfrac{489}{\sqrt{108000}}=1.488

Then, we can calculate the t-statistic as:

t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{1378-1000}{1.488}=\dfrac{378}{1.488}=254.036

The degrees of freedom for this sample size are:

[tex]df=n-1=108000-1=107999[/tex]

This test is a right-tailed test, with 107999 degrees of freedom and t=254.036, so the P-value for this test is calculated as (using a t-table):

[tex]\text{P-value}=P(t>254.036)=0[/tex]

As the P-value (0) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

At a significance level of 0.05, there is enough evidence to support the claim that the online platform was accessed significantly more so than before the stay at home order.

The effect size can be estimated with the Cohen's d.

This can be calculated as:

[tex]d=\dfrac{M-\mu}{\sigma}=\dfrac{1378-1000}{489}=\dfrac{378}{489}=0.77[/tex]

The values of Cohen's d between 0.2 and 0.8 are considered "Medium", so in this case, the effect size d=0.77 is medium.

The point (3, 6) is on the graph of y= 5f(2(x+3))-4 . Find the original point on the graph of y=f(x).

Answers

Answer:

(12, 2) is the original point on the graph of [tex]y=f(x)[/tex].

Step-by-step explanation:

Given:

[tex]y= 5f(2(x+3))-4[/tex] has a point (3, 6) on its graph.

To find:

Original point on graph [tex]y=f(x)[/tex] = ?.

Solution:

We are given that The point (3, 6) is on the graph of [tex]y= 5f(2(x+3))-4[/tex]

If we put x = 3 and y = 6 in [tex]y= 5f(2(x+3))-4[/tex], it will satisfy the equation.

Let us the put the values and observe:

[tex]6= 5f(2(3+3))-4\\\Rightarrow 6= 5f(2(6))-4\\\Rightarrow 6= 5f(12)-4\\\Rightarrow 6+4=5f(12)\\\Rightarrow 5f(12)= 6+4\\\Rightarrow 5f(12)= 10\\\Rightarrow f(12)= \dfrac{10}{5}\\\Rightarrow f(12)= 2\\OR\\\Rightarrow 2=f(12)[/tex]

Now, let us compare the above with the following:

[tex]y=f(x)[/tex]

we get y = 2 and x = 12

So, the original point on graph of [tex]y=f(x)[/tex] is (12, 2).

so

[tex]4 = x \\ 10 = 5[/tex]

Step-by-step explanation:

B1 = 4

M1 = 5

B2 = 10

M2 = x (we have to find this)

Since it is an inverse proportion (more builders will take less time and vive versa), we'll write it in the order of

=> B1 : B2 = M2 : M1

=> 4:10 = x : 5

Product of Means = Product of Extremes

=> 10*x = 4*5

=> 10x = 20

Dividing both sides by 10

=> x = 2 months

So, it will take 2 months to build classrooms by 10 builders.

In the probability distribution to the​ right, the random variable X represents the number of marriages an individual aged 15 years or older has been involved in. Compute and interpret the mean of the random variable X.

Answers

The table of the probability is missing, so i have attached it.

Answer:

μ = 0.919

The interpretation of this is that;on the average, an individual aged 15 years or older has been involved in 0.919 marriages.

Step-by-step explanation:

The expected value which is also called mean value is denoted by the symbol μ. It is defined as the sum of the product of each possibility x with it's probability P(x) as the formula;

μ = Σx.P(x) = (0 × 0.272) + (1 × 0.575) + (2 × 0.121) + (3 × 0.027) + (4 × 0.004) + (5 × 0.001)

μ = 0.919

Thus, the interpretation of this is that;on the average, an individual aged 15 years or older has been involved in 0.919 marriages.

The interpretation of the mean of the random variable X is 0.919.

Calculation of the mean:

Here the interpretation should represent the average and it should be individual aged 15 years or more so it should be involved in 0.919 marriage.

Now the mean is

μ = Σx.P(x) = (0 × 0.272) + (1 × 0.575) + (2 × 0.121) + (3 × 0.027) + (4 × 0.004) + (5 × 0.001)

μ = 0.919

Hence, The interpretation of the mean of the random variable X is 0.919.

2x+7y=-7
-4x-3y=-19​

Answers

Answer:

(7, -3)

Step-by-step explanation:

Isolate x for 2x +7y = -7:

x = (-7 - 7y)/2

Substitute:

-4((-7 - 7y) / 2) - 3y = -19

Solve for y:

-2(-7y - 7) - 3y =

14y + 14 - 3y =

11y + 14 = -19

11y = -33

y = -3

Substitute -3:

x = (-7 - 7(-3))/2

  = 14/2

x = 7
