A source of money that allows individuals to pay for goods and services later is called consumer credit and an advantage of this source of money is that there are no interest charges.

Consumer credit, also known as consumer debt, enables the consumers to incur debt or borrow money and to defer repayment of that money over time. It allows consumers to buy goods without having to pay for them in cash at the time of purchase. Examples of consumer credit include credit cards, student loans, etc. Among the advantages of using consumer credit is that there is no interest charge to borrow the money for a certain period of time until the due date.

Answer:

B. shifting

Step-by-step explanation:

When the price is rising or shifting higher, the demand curve moves to the left. But, t here is a corresponding change in the demand curve in that scenario while the cost stays unchanged. Since it relies on variables other than price, the simultaneous shift might go either left or right. However, the upward-pointing line depicts a rise in price and a fall in supply. 

Step-by-step explanation:

a) To form a committee of 8 with 3 prefects, we need to choose 3 prefects from the 5 available prefects, and 5 non-prefects from the remaining 7 boys. We can do this by using the combination formula:

Number of ways = (Number of ways to choose 3 prefects) × (Number of ways to choose 5 non-prefects)

Number of ways to choose 3 prefects from 5 = C(5, 3) = 10

Number of ways to choose 5 non-prefects from 7 = C(7, 5) = 21

Therefore, the total number of committees of 8 with 3 prefects that can be formed is:

Number of ways = 10 × 21 = 210

b) To form a committee of 8 with at least 3 prefects, we need to consider two cases: one where we choose exactly 3 prefects, and one where we choose all 5 prefects. We can calculate the number of ways for each case using the combination formula:

Number of ways to choose exactly 3 prefects and 5 non-prefects = C(5, 3) × C(7, 5) = 210

Number of ways to choose all 5 prefects and 3 non-prefects = C(5, 5) × C(7, 3) = 35

Therefore, the total number of committees of 8 with at least 3 prefects that can be formed is:

Number of ways = (Number of ways to choose exactly 3 prefects and 5 non-prefects) + (Number of ways to choose all 5 prefects and 3 non-prefects)

Number of ways = 210 + 35 = 245

The cost of the car for the year is $3800 for Nerida Kyle and it will cost less than lyft.

The cost of the car for the year will be calculated based on the amount she will spend in total on the car. The formula to be used is -

Total cost = Cost price of the car - Selling price

Cost price of car will be sum of all the expenses, calculated as follows -

Cost price of the car = 15000 + 1200 + 800 + 300

Performing addition on Right and Side of the equation

Cost price of the car = $17,300

Total cost for the year = 17,300 - 13,500

Performing subtraction on Right and Side of the equation

Total cost for the year = $3,800

Hence, Nerida Kyle will spend $3,800 on car which is better than lift.

Step-by-step explanation:

302 necklaces × $5 each = $1510 total

The blanks in each statement about the line segment should be completed as shown below.

Since we know U is the midpoint, we can say TU=8x + 11 substituting in our values for each we get:

8x + 11 = 12x - 1

Solve for x

We now want to solve for x.

−4x+11=−1

−4x = -12

x= 3

Solve for TU, UV, and TV

This is just the first part of our question. Now we need to find TU, UV, and TV. Lets start with TU and UV.

TU=8x+11 We know that x=3 so let’s substitute that in.

TU=8(3)+11

TU= 35

We will do the same for UV. From our knowledge of midpoint, we know that TU should equal UV, however let’s do the math just to confirm.

UV=12x−1 We know that x=3 so let’s substitute that in.

UV=12(3)−1

UV= 35

Based on the segment addition postulate, we have:

TU+UV=TV

35+35=TV

TV= 70

Find the detailed calculations below;

TU = UV

8x + 11 = 12x - 1

8x + 11 - 11 = 12x - 1 - 11

8x = 12x - 12

8x - 12x = 12x - 12 - 12x

-4x = -12

x = 3

By using the substitution method to substitute the value of x into the expression for TU, we have:

TU = 8x + 11

TU = 8(3) + 11

TU = 24 + 11

TU = 35

By applying the transitive property of equality, we have:

UV = TU and TU = 15, then UV = 35

By applying the segment addition postulate, we have:

TV = TU + UV

TV = 35 + 35

TV = 70

Answer:

Step-by-step explanation:

Now we have to,

→ find the value of each angle.

Forming the equation,

→ 90° + (p - 10°) + (p + 50°) = 180°

Now the value of p will be,

→ 90° + (p - 10°) + (p + 50°) = 180°

→ (90° - 10° + 50°) + (p + p) = 180°

→ 130° + 2p = 180°

→ 2p = 180° - 130°

→ p = 50°/2

→ [ p = 25° ]

Then the value of other angle is,

→ p - 10° || → p + 50°

→ 25° - 10° || → 25° + 50°

→ 15° || → 75°

Hence, these are the angles.

The exact values of a and b in the right triangle are (a) a = 5, b = 5√3

From the question, we have the following parameters that can be used in our computation:

The right triangle (see attachment)

The exact values of a and b can be calculated from:

sinθ = opp/hyp

cosθ = adj/hyp

tanθ = opp/adj

Using the above as a guide, we have the following:

sin30 = a/10

1/2 = a/10

2a = 10

This gives

a = 5

Using Pythagorean theorem, we have

10² = b² + 5²

100 = 25+b²

b² = 100-25

b² = 75

This gives

b = 5√3

Hence, the exact value of a is 5 and b is 5√3

To determine which option gives a better chance of winning, we need to calculate the expected number of A's and B's in the 1,000 draws and compare it to the conditions for winning in each option.

Let's calculate the expected number of A's and B's:

Number of A's in "ARABIA": 3

Number of B's in "ARABIA": 1

Total number of letters in "ARABIA": 6

Probability of drawing an A: 3/6 = 1/2

Probability of drawing a B: 1/6

Expected number of A's in 1,000 draws: (1/2) * 1,000 = 500

Expected number of B's in 1,000 draws: (1/6) * 1,000 = 166.67

Now let's analyze the conditions for winning in each option:

Option A: You win a dollar if the number of A's among the draws is 10 or more above the expected number (500 + 10 = 510 or more).

Option B: You win a dollar if the number of B's among the draws is 10 or more above the expected number (166.67 + 10 = 176.67 or more).

Comparing the two options:

Option A requires having 510 or more A's out of the 1,000 draws.

Option B requires having 176.67 or more B's out of the 1,000 draws.

Since it is not possible to have a fraction of a letter, the number of B's will always be an integer. Therefore, it is impossible to reach the condition for winning in option B, as there can't be 176.67 B's.

Therefore, the correct answer is:

(i) Option A gives a better chance of winning than option B.

7a. The profit at the cutoff probability set by the bank is $20,000, 7b. The lift ratio at the cutoff point is 3.5 and 7c. The lowest possible value of the first decile is 0.1.

To answer 7a and 7b, we need to calculate the number of good and bad applicants who are correctly and incorrectly classified. The following table shows the results of this calculation:

Classification Good Bad

Correct          270        80

Incorrect   30        160

The profit at the cutoff probability is calculated as follows:

Profit = (profit from correctly classifying good applicants) + (profit from incorrectly classifying bad applicants) - (loss from incorrectly classifying good applicants) - (loss from correctly classifying bad applicants)

Plugging in the numbers from the table, we get the following profit:

Profit = (1000 * 270) + (0 * 80) - (5000 * 30) - (0 * 160) = $20,000

The lift ratio is calculated as follows:

Lift Ratio = (profit with data mining tool) / (profit with random selection)

Plugging in the numbers from the table, we get the following lift ratio:

Lift Ratio = (20000 / 0) = 3.5

To answer 7c, we need to calculate the number of good applicants who are incorrectly classified as bad. The following table shows the results of this calculation:

Classification   Good Bad

Correct                270        80

Incorrect          30           160

The number of good applicants who are incorrectly classified as bad is 30. The lowest possible value of the first decile is therefore 0.1, which is the fraction of good applicants who are incorrectly classified as bad.

Here are some additional explanations:

The profit at the cutoff probability is the total amount of money that the bank makes by using the data mining tool to make loan decisions. The lift ratio is a measure of how much better the data mining tool is at making loan decisions than random selection.

The lowest possible value of the first decile is the fraction of good applicants who are incorrectly classified as bad.
