companies often win in a credit transaction, due to their clients continually pay them for their usage.

Final answer:

The 'winner' in a credit transaction varies; it could be the lender earning interest or the borrower who benefits from immediate funds. Credit transactions do not create new money but reallocate it, and for personal debt management, debts with higher interest should be paid first.

Explanation:

In credit transactions, the winner is not easily defined as it depends on the perspective and the outcome of the transaction. If we consider a credit card transaction where a customer makes a purchase, the credit card issuer initially appears to win by providing funds to the customer and earning interest on the borrowed amount. The customer benefits by receiving the goods or services they need immediately, with the expectation of repaying the funds.

In a typical credit transaction, one party relinquishes money today while the other party promises to return a specified sum, possibly with interest, at a future date. This does not create new money but shifts existing money from one party to another. The perceived 'winner' could be the lender, who will receive the original amount plus interest, or the borrower, who gets immediate use of the funds.

When managing personal finances, it's advisable to pay off debts with the highest interest rates first, as suggested by the adage, "A penny saved is a penny earned".

Answer:

V=2x4x5

Step-by-step explanation:

Volume of a solid can be obtained by multiplying lengths of all the three dimensions i.e. Length, width and height.

[tex]V = l \times b \times h \\ \therefore V = 2 \times 4 \times 5[/tex]

The Volume of Solid is, V=2x4x5.

Answer:56 students

Step-by-step explanation:

So look 6th grade total 42 and 8th is 72 and the total is 170 but he want 7th grade total so what I did is 42+72=114

Then I did 170-114=56 so the total of 7th grade is 56.

The value of the variables x, y, and z will be 45, 24, and 56.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

Total                        101                 69                 170

Then the value of x, y, and z are calculated below.

For value of z, the equation will be

72 = z + 27

 z = 72 – 27

 z = 45

For value of x, the equation will be

18 + x + 27 = 69

      x + 45 = 69

              x = 69 – 45

              x = 24

For value of y, the equation will be

y = 32 + 24

y = 56

Then the value of the variables x, y, and z will be 45, 24, and 56.

Answer:

[tex]n\geq 23[/tex]

Step-by-step explanation:

-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:

[tex]n\geq (\frac{z\sigma}{ME})^2[/tex]

Where:

We substitute our given values to calculate the sample size:

[tex]n\geq (\frac{z\sigma}{ME})^2\\\\\geq (\frac{1.96\times 12}{5})^2\\\\\geq 22.13\approx23[/tex]

Hence, the smallest desired sample size is 23

Hernando needs to take a sample size of at least 23 members.

To determine the smallest sample size required for Hernando to achieve a 95% confidence interval with a margin of error no more than 5 years, we can use the formula:

n = (Z * σ / E)²

where:

Plugging in the values, we get:

n = (1.96 * 12 / 5)²
n = (23.52 / 5)²
n = (4.704)²
n ≈ 22.14

Since the sample size must be a whole number, we round up to the nearest integer, making the smallest required sample size n = 23.

Answer: the efficiency of the first car is 25 miles per gallon.

the efficiency of the second car is 30 miles per gallon.

Step-by-step explanation:

Let x represent the efficiency of the first car.

Let y represent the efficiency of the second car.

Distance = car efficiency × number of gallons.

The first car consume 25 gallons of gas and the second consumed 15 gallons of gas. The two cars Drove a combined total of 1075 miles. It means that

25x + 15y = 1075- - - - - - - - - - -1

The sum of the fuel efficiencies was 55 miles per gallon. It means that

x + y = 55

Substituting x = 55 - y into equation 1, it becomes

25(55 - y) + 15y = 1075

1375 - 25y + 15y = 1075

- 25y + 15y = 1075 - 1375

- 10y = - 300

y = - 300/-10

y = 30

x = 55 - y = 55 - 30

x = 25

To apply two coats of paint on all the walls, you will need to buy 4 quarts of paint.

To find out how many quarts of paint you need to buy to apply two coats of paint on all the walls, we need to calculate the total area that needs to be painted.

If 2 quarts cover 175 square feet, then 1 quart covers 175/2 = 87.5 square feet.

Since you need to apply two coats of paint, the total area that needs to be painted is 175 square feet x 2 = 350 square feet.

To find out how many quarts you need, divide the total area by the area covered by 1 quart: 350 square feet / 87.5 square feet/quart = 4 quarts.

You will need to buy 4 quarts of paint to complete the job.

Answer:

(1,4), (2,2) (3,0)

Step-by-step explanation:

adjust the equation so that the y is isolated so subtract 4 x

2y=4x +12

Every number is divisible by 2 so you can further isolate the y

y=-2x+6

Plug your x coordinates into the equation so get the y coordinates

Answer:

y=-2x+6

Step-by-step explanation:

You want to to turn the given equation 4x+2y=12 into y=mx+b

** m is the slope and b is the y-intercept

The first step is to isolate y. First subtract 4x from both sides:

4x+2y=12

2y=-4x+12

Now you have y mostly isolated, all you have to do is divide both sides by 2:

2y=-4x+12

y=-4/2x +12/2

y=-2x +6

Now you have your equation, plug in values for x to find y to fill in the table:

ex: y=-2(2)+6

y= -4+6

y= 2

** an order pair ex.: (2,2)

Answer:

210xy

Step-by-step explanation:

15x * 14y can be written as 15 * x * 14 * y. Due to the commutative property of multiplication, we can change around the order of these numbers to make this expression easier to understand.

We're going to move the expression around so it is now 15 * 14 * x * y. Now, you can see clearly that you can multiply 15 and 14 together, which will get you 210.

And naturally what you have left is 210 * x * y, which simply appears as 210xy.

Answer:

Hence the Distance from each other chord to center  is 84 inches.

Step-by-step explanation:

Given:

Diameter =170 inches

2 chords with each length =26 inches.

To Find:

Distance of each chord from the circle.

Solution:

Consider a circle with center as O ,

And OA as Radius

(Refer the attachment)

So as chord be BC and DE respectively with each of 26 length

They have both same length so they should located at same distance from center but as mirror images of each other opposite side of the diameter as shown in fig.

Hence we can calculate for one chord as follows:

Radius =diameter/2=170/2=85

r=85 inches.

Let distance from center t o chord be 'x'

Now draw perpendicular to chord BC with F as midpoint for chord and join endpoints  of chord to the center which forms triangle OFC as right angled triangle,

By using pythagorus Theorem

[tex]OC^2=FC^2+OF^2[/tex]

Here OC=85 inches , FC=26/2=13 inches.

So

[tex]85^2=13^2+OF^2[/tex]

[tex]OF^2=85^2 -13^2[/tex]

[tex]OF^2=7225-169[/tex]

[tex]OF^2=[/tex]7056

[tex]OF=84[/tex] inches

Hence the Distance from each other chord to center  is 84 inches.

Answer:

Area of the square base: 144 in²

Area of each triangular face: 66 in²

Amount of paint needed: 408 in²

Step-by-step explanation:

We basically want to find the surface area of this square pyramid.

First, find the areas of the 4 triangular sides. The area of a triangle is denoted by: [tex]A=\frac{1}{2} bh[/tex], where b is the base and h is the height.

Here, the base coincides with the side length of the square, so b = 12. The height is 11, so h = 11. Plug these in:

[tex]A=\frac{1}{2} bh[/tex]

[tex]A=\frac{1}{2}[/tex] * 12 * 11 = 66 inches squared

Each triangular face is thus 66 inches squared.

Since there are 4 triangles, multiply 66 by 4: 66 * 4 = 264 inches squared

Now, find the area of the square base. The area of a square is: A = s * s, where s is the side length. Here, the side length is 12, so s = 12. Plug this into the equation:

A = s * s

A = 12 * 12 = 144

So, the square base is 144 inches squared.

Finally, add 144 to 264 to get the total area Gabriel needs to paint:

144 + 264 = 408 inches squared

Answer:

The area of the square base is 144 in²

The area of each triangular face is 66 in²

Gabriel will need 408 in² of paint.

Step-by-step explanation:

The area of the square base is:

12² = 144 in²

The area of each triangular face:

½(12×11) = 66 in²

Gabriel will need:

4(66) + 144 = 408 in²

The number 31 was increased to 44 by approximately 41.9%.

To calculate the percentage increase, you can use the formula:

[tex]\[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100 \][/tex]

In this case, the original value is 31, and the new value is 44. Plug these values into the formula:

[tex]\[ \text{Percentage Increase} = \left( \frac{44 - 31}{31} \right) \times 100 \][/tex]

[tex]\[ \text{Percentage Increase} = \left( \frac{13}{31} \right) \times 100 \][/tex]

Now, calculate the percentage increase:

[tex]\[ \text{Percentage Increase} \approx 41.9\% \][/tex]

So, the number 31 was increased to 44 by approximately 41.9%.

The number 31 was increased by approximately [tex]\( \boed{41.9\%} \)[/tex] to become 44.

Step 1

To find the percentage increase from 31 to 44, we can use the formula for percentage increase:

[tex]\[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100\% \][/tex]

Step 2

Given:

- Old value (31)

- New value (44)

[tex]\[ \text{Percentage Increase} = \left( \frac{44 - 31}{31} \right) \times 100\% \]\[ \text{Percentage Increase} = \left( \frac{13}{31} \right) \times 100\% \]\[ \text{Percentage Increase} \approx 0.419 \times 100\% \]\[ \text{Percentage Increase} \approx 41.9\% \][/tex]

So, the number 31 was increased by approximately [tex]\( \boed{41.9\%} \)[/tex] to become 44.

(a) The mean is 24

The Absolute deviation is 8.367

(b) Mean is the number of score per game

(b)  The standard  deviation is the normal expected score difference from the mean

(c) Mean reduce

Standard deviation reduce

Step-by-step explanation:

The data is as follows;

21, 45, 21, 14, 21, 28, 24, 14, 24, 28

The  data with n = 10 is presented as follows

x             (x - μ)       (x - μ)²

21      -3         9

45         21         441

21            -3         9

14        -10        100

21         -3            9

28           4        16

24         0       0

14        -10        100

24         0            0

28     4       16

∑x/n =240  ∑(x - μ)²  =  700

24     ∑(x - μ)²/n = σ² = 70

The mean = 24

The Absolute deviation √70 = 8.367

(b) The mean indicates that within the football season, the average game score per game was 24 and the normal variation from the average was 8.367

(c) Removing the outlier, 45 which ls most equal to two means will reduce the mean or average score per game of the team  to as follows

21 ,  21 , 14,  21,  28,  24,  14,  24,  28

∑x = 195 and μ = (∑x)/n = 195/9 = 21.67

The standard deviation = 4.83

Therefore, removing the outlier 45 which is almost double the mean will reduce the mean by almost μ/n and the standard deviation is also reduced.

The divisors of 240 which are multiples of tens are 10, 20, 30, and 60.

To identify divisors of 240 that are multiples of tens, we must first understand what a divisor is. A divisor is a number that divides another number evenly. For example, in the case of 240, some notable divisors are 1, 2, 3, 4, 5, and so on. However, we are specifically looking for divisors that are themselves multiples of 10. These are numbers that end in zero and could be multiplied by some integer to get 240. In this instance, four such divisors are 10, 20, 30, and 60. For each of these examples, one can multiply these by a whole number to produce 240. For instance, 10*24 is 240, so is 20*12, 30*8, and 60*4.
