Adding a constant to all the data points does NOT change the correlation

Interchanging X and Y changes the correlation

Correlation has no units

Outliers do NOT effect the correlation

If r is close to 1 then it is a strong positive correlation

Correlation could be positive or negative

Correlation and y-intercept have the same sign

Answers

Answer 1

The True statements about the correlation are: (1), (2), (3), (5), (6) and (7)

1) We know that the adding, subtracting, multiplying or dividing a constant to all of the data points in one or both variables does not change the correlation coefficient.

So, the first statement is True.

2) We know that the correlation measures the strength of the pattern around a line of regression as well as the direction of the line. So, interchanging the variables would not change the correlation. The correlation between x and y is the same as the correlation between y and x.

Thus the second statement is True.

3) We know that the correlation coefficient does not have any units.

It is just a number between -1 to +1.

Thus the third statement is True.

4) We know that the outlier may weaken the correlation. It makes the data more scattered. So the correlation coefficient r gets closer to 0.

Thus the fourth statement is False.

5) We know that if the correlation coefficient r is close to 1 then it is a strong positive correlation and if r is close to -1 then it is a strong negative correlation.

Thus the fifth statement is True.

6) We know that the corrletaion coefficient values can range from -1 to 1.

Thus the sixth statement is True.

7) We know that the y-intercept is nothing but the point at which the regression line intercepts the y-axis. The y-intercept of the regression line and the correlation coefficient have the same sign.

Thus the seventh statement is True.

A certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 5 students' scores on the exam after completing the course:
2,14,1,2,−6
Using these data, construct a 90% confidence interval for the average net change in a student's score after completing the course. Assume the population is approximately normal.
Step 3 of 4 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

Answers

The critical value that should be used in constructing the confidence interval is 2.132 (rounded to three decimal places).

What is Critical value ?

In statistics, a critical value is a threshold value that is used to determine whether to reject or fail to reject the null hypothesis in a statistical test. It is typically based on the significance level of the test, which is the probability of rejecting the null hypothesis when it is actually true.

To find the critical value for a 90% confidence interval with n = 5, we need to use a t-distribution with (n-1) degrees of freedom.

Using a t-distribution table or a calculator, we can find the critical value with a 90% confidence level and 4 degrees of freedom (n-1 = 5-1 = 4) to be approximately 2.132.

Therefore, the critical value that should be used in constructing the confidence interval is 2.132 (rounded to three decimal places).

A catering service offers 5 appetizers, 11 main courses, and 4 desserts. A customer is to select 4 appetizers, 9 main courses, and 3 desserts for a banquet. In how many ways can this be done?

Answers

To calculate the total number of ways the customer can select 4 appetizers, 9 main courses, and 3 desserts, we can use the formula for combinations:

Total number of ways = (Number of ways to select appetizers) x (Number of ways to select main courses) x (Number of ways to select desserts)

Number of ways to select appetizers = C(5,4) = 5

Number of ways to select main courses = C(11,9) = 330

Number of ways to select desserts = C(4,3) = 4

Therefore, the total number of ways the customer can select 4 appetizers, 9 main courses, and 3 desserts is:

Total number of ways = 5 x 330 x 4 = 6,600

So, there are 6,600 ways the customer can select the items for the banquet.

There are 1100 many ways can be done that is when catering service offers 5 appetizers, 11 main courses, and 4 desserts.

Given that,

A catering service offers 5 appetizers, 11 main courses, and 4 desserts. A customer is to select 4 appetizers, 9 main courses, and 3 desserts for a banquet.

We have to find how many ways can this be done.

We know that,

Number of appetizers offered = 5

Number of appetizers customer is to select = 4

Number of main courses offered = 11

Number of main courses customer is to select = 9

Number of desserts offered = 4

Number of desserts the customer is to select = 3

On the axes below sketch the graph of y = 4x² + 8x +3
Label all points of intersection and the turning point in your sketch.

Answers

1. Find the vertex (turning point) of the parabola by using the formula x = -b/2a, where a = 4 and b = 8. This gives x = -1, which is the x-coordinate of the vertex. To find the y-coordinate, substitute x = -1 into the equation: y = 4(-1)² + 8(-1) + 3 = -1.

2. Plot the vertex at the point (-1, -1).

3. To find the x-intercepts, set y = 0 in the equation and solve for x. This gives x = (-8 ± √(8² - 4(4)(3)))/(2(4)) = (-8 ± √16)/8 = -1/2 or -3. Plot these points on the x-axis.

4. To find the y-intercept, set x = 0 in the equation and solve for y. This gives y = 3, so the y-intercept is at the point (0, 3).

(b) If the department store marks up the wholesale price of the refrigerator by 50%, then the price at the store would be:

Wholesale price + (50% x Wholesale price) = $549 + (0.5 x $549) = $823.50

If Josh would receive a 10% discount off the in-store price, then the price he would pay would be:

In-store price - (10% x In-store price) = $823.50 - (0.1 x $823.50) = $741.15

(c) If the superstore marks up the wholesale price of the refrigerator by 40%, then the price at the store would be:

Wholesale price + (40% x Wholesale price) = $549 + (0.4 x $549) = $768.60

Therefore, Josh would pay $768.60 for the refrigerator at the superstore.

Comparing the prices, we can see that Josh would pay less for the refrigerator at the department store after factoring in the discount:

How much money should Be deposited today in an account that earns 10.5 percent compounded monthly so that it will accumulate to $22,000 in four years

Answers

Answer:

$12,276.24

Step-by-step explanation:

22000 / (1 + 0.105/12)^4*12

12276.24

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where A is the future value, P is the present value, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, we want to find the present value P that will accumulate to $22,000 in four years at an annual interest rate of 10.5% compounded monthly (i.e., n = 12). Therefore, we have:

A = $22,000
r = 0.105/12 (monthly interest rate)
n = 12
t = 4

Substituting these values into the formula and solving for P, we get:

P = A/(1 + r/n)^(nt) = $22,000/(1 + 0.105/12)^(12*4) ≈ $14,005.70

Therefore, the amount that should be deposited today in the account is approximately $14,005.70.

The original price of this car is equal to $6,600.

What is a percentage?

In Mathematics, a percentage can be defined as any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.

Assuming the original price is represented by the variable x, we have the following:

12.5/100 × x = x - 5,775

0.125x = x - 5,775

5,775 = (x - 0.125x)

5,775 = 0.875x

x = 5,775/0.875

x = $6,600.

A subscription to a live streaming program normally costs $29 but is on sale for 25% off. An 8% tax is added at checkout. What is the total cost?

$7.25
$21.75
$23.49
$39.15

Answers

$23.49, $7.25 is how much money you get off, the sale price is $21.75 before tax, after tax it’s 23.49.

A subscription to a live streaming program normally costs $29 but is on sale for 25% off. An 8% tax is added at checkout then the total cost is $23.49.

To calculate the total cost, first, we find the discounted price of the subscription. A 25% discount on $29 is calculated by multiplying $29 by 0.25 (25% as a decimal), which gives us a discount of $7.25. Subtracting the discount from the original price, we get the discounted price of $29 - $7.25 = $21.75.

Next, we need to add the 8% tax to the discounted price. To calculate the tax amount, we multiply $21.75 by 0.08 (8% as a decimal), which gives us $1.74. Adding this tax amount to the discounted price, we get the total cost as $21.75 + $1.74 = $23.49.

Step 1: Calculate the discount amount:

Discount = 25% of $29

Discount = 0.25 * $29

Discount = $7.25

Step 2: Find the discounted price:

Discounted Price = Original Price - Discount

Discounted Price = $29 - $7.25

Discounted Price = $21.75

Step 3: Calculate the tax amount:

Tax Amount = 8% of Discounted Price

Tax Amount = 0.08 * $21.75

Tax Amount = $1.74

Step 4: Calculate the total cost:

Total Cost = Discounted Price + Tax Amount

Total Cost = $21.75 + $1.74

Total Cost = $23.49

So, the total cost after applying the 25% discount and adding an 8% tax at checkout is $23.49.

- Discount = 0.25 * $29 = $7.25

- Discounted Price = $29 - $7.25 = $21.75

- Tax Amount = 0.08 * $21.75 = $1.74

- Total Cost = $21.75 + $1.74 = $23.49

Use mathematical induction to prove 2^n>=2n is true for all positive integers.

Answers

By the Principle of Mathematical Induction, 2ⁿ≥2n is true for all positive integers.

The given inequality is 2ⁿ≥2n.

Let n = 1

2^1 ≥ 2^1

2 ≥ 2 which is true

Inductive Step: Assume 2ⁿ≥2n is true for some arbitrary positive integer k.

We need to prove that 2^(k+1) ≥ 2^(k+1)

2^(k+1) ≥ 2*2^k (by the inductive hypothesis)

2^(k+1) ≥ 2*2^(k+1)

2^(k+1) ≥ 2^(k+1) which is true

Therefore, by the Principle of Mathematical Induction, 2ⁿ≥2n is true for all positive integers.

The half-life of the particular compound is approximately 9.4 days. (Correct choice: B)

How to find the half-life of a compound

The statement indicates the decay function of a particular compound, which is an exponential function of the form:

y = a · exp(- λ · t)

Where:

a - Initial mass of the compound.λ - Decay constant, in days⁻¹.t - Time, in days.

The half-life of the particular compound is determined by the following expression:

t = ㏑ 2 / λ

Where t is the half-life.

If we know that λ = 0.0736, then the half-life of the particular compound is:

t = ㏑ 2 / 0.0736

t = 9.4 days

The amount of money in a savings account increases by 0.2% every month.

Part A

Write a function for the amount of money in the account, B, after t months with an initial deposit of $100.

B(t) =
(
)t

Part B

By what factor does the amount in the account increase every month? Every year? Every 5 years? Round answers to the nearest thousandth.

each month:


each year:


every five years:

Answers

a) A function for the amount of money in the account, B, after t months with an initial deposit of $100 isB(t) = [tex]100(1 + 0.002)^t[/tex]

b) The amount in the account increases by a factor of approximately 1.002 every month, approximately 1.025 every year and approximately 1.099 every five years.

a) The function for the amount of money in the account after t months with an initial deposit of $100 and an increase of 0.2% per month can be written as:

B(t) = [tex]100(1 + 0.002)^t[/tex]

where t is the number of months.

b) To determine the factor by which the amount in the account increases every month, year, and five years, we can calculate the value of the function for t = 1, t = 12, and t = 60, respectively, and then divide each value by the previous one.

For each month:

B(1) = 100(1 + 0.002) = $100.20

B(2) = 100(1 + 0.002)² = $100.40

B(2)/B(1) = $100.40/$100.20 = 1.001993

The amount in the account increases by a factor of approximately 1.002 every month.

For each year:

B(12) = 100(1 + 0.002)¹² = $102.44

B(24) = 100(1 + 0.002)²⁴ = $105.01

B(24)/B(12) = $105.01/$102.44 = 1.0249

The amount in the account increases by a factor of approximately 1.025 every year.

For every five years:

B(60) = 100(1 + 0.002)⁶⁰ = $110.41

B(120) = 100(1 + 0.002)¹²⁰ = $121.20

B(120)/B(60) = $121.20/$110.41 = 1.0991

The amount in the account increases by a factor of approximately 1.099 every five years. Therefore, the amount in the account increases by a small factor every month, a moderate factor every year, and a larger factor every five years.
