Enter your answer in the box

Answer:

$7000

Step-by-step explanation:

For simple interest,

I = Prt,

where I = amount of interest earned

P = principal amount, the amount of the investment

r = annual interest rate (convert percent to decimal for calculations)

t = time (number of years)

I = Prt

We know I, r, and t, and we need to solve for P.

1120 = P × 4% × 4

Convert percent to decimal.

1120 = P × 0.04 × 4

Multiply on the right side.

1120 = 0.16P

Divide both sides by 0.16

7000 = P

Answer: $7000

The expected profit for the first mall is $1,750,000

Given data ,

Let the probability be represented as A and B

Now , For Event A:

Probability of success at the first mall (P(A)) = 2 (given)

Profit if successful (P(A) * Profit | Success) = 2 * $1,050,000 = $2,100,000

Loss if unsuccessful (Loss | Failure) = -$350,000

For Event B:

Probability of success at the second mall (P(B)) = unknown (to be calculated)

Profit if successful (P(B) * Profit | Success) = P(B) * $700,000

Loss if unsuccessful (Loss | Failure) = -$210,000

Expected Profit for Event A = P(A) * Profit | Success + (1 - P(A)) * Loss | Failure

Expected Profit for Event A = 2 * $1,050,000 + (1 - 2) * -$350,000

Expected Profit for Event A = $2,100,000 - $350,000

Expected Profit for Event A = $ 1,750,000

Hence , the profit is $ 1,750,000

Step-by-step explanation:

-2/3x + -21/4 = 27/4

Jay's score for the last quiz is 14.

Let's use the formula for finding the mean:

Mean = (Sum of all scores) / (Number of scores)

We can rearrange this formula to solve for the unknown score:

Unknown score = (Mean x Number of scores) - (Sum of all other scores)

Given that Jay's mean score for four quizzes is 9, we have:

Mean = 9

Number of scores = 4

Jay's scores for the first three quizzes are 8, 5, and 9. The sum of these scores is:

Sum of first three scores = 8 + 5 + 9 = 22

Using the formula above, we can find Jay's score on the fourth quiz:

Unknown score = (Mean x Number of scores) - (Sum of all other scores)

Unknown score = (9 x 4) - 22

Unknown score = 36 - 22

Unknown score = 14

Answer:

Since f is increasing over its domain, we know that if a > b, then f(a) > f(b). Therefore, we have:

2x + 3 > 3x - 2

Solving for x, we get:

x < 5

So the solution set is:

Df = [3, infinity) intersect (-infinity, 5) = [3, 5)

Therefore, the inequality is true for all x in the interval [3, 5).

Since f is increasing over its domain, we know that if a > b, then f(a) > f(b). Therefore, we have:

x^2 - 2 < y^2 - 2

Simplifying, we get:

x^2 < y^2

Taking the square root of both sides, we get:

|x| < |y|

So the solution set is:

Df = [3, infinity)

|x| < |y| means that either x < y or -x < y. Therefore, the solution set can be divided into two parts:

Part 1: x^2 - 2 < 0, i.e., x is in the interval (-sqrt(2), sqrt(2)). For this part, we have:

Df intersect (-sqrt(2), sqrt(2)) = empty set

Part 2: x^2 - 2 >= 0, i.e., x is outside the interval (-sqrt(2), sqrt(2)). For this part, we have:

Df intersect (-infinity, -sqrt(2)] union [sqrt(2), infinity) = [3, infinity)

Therefore, the inequality is true for all x in the interval [3, infinity) except for the interval (-sqrt(2), sqrt(2)).

Step-by-step explanation:

1) The scale factor of dilation is 1/3

2) The orientation is preserved in dilation of A to A'

3) The congruence is not preserved in dilation of A to A'

We know that the scale factor is nothing but the ratio of the size of the transformed image to the size of the original image.

Here from the attached graph we can observe that the square A is transformed to A'

The side length of square A is 18 units and the side length of square A' is 6

So, the scale factor would be,

r = A' / A

r = 6/18

r = 1/3

We know that a dilation preserves the shape and orientation of the figure, but changes the size of he figure.

So, the dilations do not preserve congruence, as it changes the size of a figure.

The probability that they are the 2 oldest people in the group is 0.011

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain.

The probability of an event A is denoted by P(A)

From the question above, let us calculate the probability.

The probability that the first person selected is the oldest is 1/10.

Then, the probability that the second person selected is the second oldest is 1/9, since there are only 9 people left to choose from.

Therefore, the probability of selecting the two oldest people in the group is:

1/10 * 1/9 = 1/90

So, the probability of selecting the two oldest people in the group is 1/90 or approximately 0.011 or 1.1%.

The probability of dying from heart disease is 0.1667 or 16.67%.

The odds in favor of an event are defined as the ratio of the probability of the event occurring to the probability of the event not occurring. In this case, the odds in favor of dying from heart disease are 1 to 5.

So, we can set up the following equation:

Odds in favor of dying from heart disease = probability of dying / probability of not dying

1/5 = probability of dying / probability of not dying

We can solve for the probability of dying by cross-multiplying:

probability of dying = odds in favor of dying from heart disease / (odds in favor of dying from heart disease + 1)

probability of dying = 1 / (1 + 5)

probability of dying = 1/6

- To answer a question about a sale transaction on rental property that closes on December 16, you need to calculate how much rent the landlord owes to the buyer for the remaining days of December.

- You can use a formula called prorated rent to calculate the amount of rent that is proportional to the number of days that the buyer owns the property. Prorated rent splits the amount between the previous and new owners of a rental property.

- The formula for prorated rent is: Prorated Rent = (Monthly Rent / Number of Days in Month) x Number of Days Rent Owed

- In your case, the monthly rent is $713, the number of days in December is 31, and the number of days rent owed is 16 (from December 16 to December 31). The closing day is the buyer's, so the landlord owes rent for that day as well.

- Plugging these values into the formula, you get: Prorated Rent = (713 / 31) x 16 = 368.26

- This means that the landlord owes $368.26 to the buyer for the remaining days of December.

Step-by-step explanation:

The quadratic function f(x) = 2x² - 16x + 24 can be rewritten in the vertex form f(x) = 2(x - 4)² + 4.

Given the function in the question:

f(x) = 2x² - 16x + 24

To determine the vertex form f(x) = a(x-h)² + k, we need to complete the square.

Factor out the leading coefficient of 2:

f(x) = 2x² - 16x + 24

f(x) = 2(x² - 8x + 12)

To complete the square, we need to add and subtract the square of half of the coefficient of x:

f(x) = 2[(x² - 8x + 16) - 4] + 8

Since (x² - 8x + 16) is a perfect square trinomial, we factored as (x - 4)².

f(x) = 2[(x - 4)² - 4] + 8

Now we can simplify and rewrite in the desired form:

f(x) = 2(x - 4)² - 4 + 8

f(x) = 2(x - 4)² + 4

Therefore, the vertex form is f(x) = 2(x - 4)² + 4.
