According to the concept of card payment, the true statement is "If you purchase an item using debit card, the money will deducted from your bank account".

Card payment:

Card payment refers any transaction whereby the Card is used to settle bills or to pay for certain goods and/or services at a Post Office branch.

Given,

Here we need to find the true statement according to the purchase.

While we looking into the given options,

The first option is incorrect because it says there is no interest for credit card purchase. This one is wrong because we have to pay interest for credit card purchase.

The second option is wrong because it tells that the money will be deducted from your account. If anyone can purchase using the credit card the money will only be deducted at the end of the month with some interest on it.

The third option is incorrect because debit card transaction are truly based on the amount within you account so it is not a borrowed one.

Therefore, the final statement is the correct one.

For the given line of best fit, equation which represents the prediction of values between the actual data points is representing an example of interpolation.

As given in the question,

Given line of best fit equation,

Here prediction is to be done for the values which are between the actual data points.

The predicted values are within the range.

Predicted values represents either extrapolation or interpolation

If predicted values are outside the actual points it is extrapolation.

Here it is between the actual data points.

So, it is interpolation.

Therefore, for the given line of best fit, equation which represents the prediction of values between the actual data points is representing an example of interpolation.

Answer:

A ≈ 314.2 units

Step-by-step explanation:

       To find the area of the circle, we will use the given formula. We are given the diameter (d), 20, and the radius (r) is half of the diameter. 20 units / 2 = 10 units for our radius (r).

               A = πr²

               A = π(10)²

               A ≈ 314.15927

       Now, we are asked to round to the nearest tenth.

               A ≈ 314.2 units

Answer:

23) $248,943.75

24) $384

Step-by-step explanation:

23) 266,250/100= 2662.5 which is 1%

     2662.5×6.5=17,306.25 which is 6.5%

     Since it is a mark up we subtract 17,306.25 from 266,250 to find the

     original price.

24) 320÷10=32 which is 10%

     32×2= 64 which is 20%

     Since it is a discount we add 64 to 320 to find the original price.

x-value that corresponds to the z-score of 2.33 is 81.65.

Mean = 70

Standard deviation = 5

z score = 2.33

Using the z-score formula:

z = (x - mean) / SD

Plug the values:

2.33 = (x-70)/5

    x = 5(2.33) +70

The equation in slope intercept form is y = -4x + 24.

From the graph:

yellow points are (6,0) and (4,8).

slope intercept form is y = mx + c.

slope m = 8 - 0 / 4 - 6

= 8/-2

= -8/2

= -4

Substitute  m and (6,0)

y = mx + c

0 = -4*6 + c

c = 24

y = mx + c

y = -4x + 24.

Therefore The equation in slope intercept form is y = -4x + 24.

The equation of the line that passes through the point (-6, 6) and (-3, 7) is y = 1 / 3 x + 8

The equation of a line in slope intercept form can be represented as follows:

y = mx + c

where

Hence, the line passes through the point (-6, 6) and (-3, 7)

m = slope = 7 - 6 / -3 + 6

m = 1 / 3

Therefore, the y-intercept of the line can be found using (-6, 6)

y = 1  /3 x + b

6 = 1 / 3 (-6) + b

6 = -2 + b

b = 6 + 2

b = 8

Therefore, the equation of the line is y = 1 / 3 x + 8

For the quadratic function y = ax² + bx + c , for which graph passes through the points (2, 31), (3 , 45) , (1, 19) is given by y = x² + 9x + 9.

As given in the question,

Standard form of quadratic function,

y = ax² + bx + c

Graph of the quadratic function passes through the points  (2, 31),

(3 , 45) , (1, 19) .

When passes through (2, 31)

31 = 4a + 2b + c __(1)

Passes through (3,45)

45 = 9a + 3b + c  __(2)

Passes through (1, 19)

19 = a + b + c __(3)

Multiply 9 to (3) and subtract (2) from it,

9a + 9b + 9c =171

9a +3b + c = 45

      6b + 8c = 126 ____(4)

Now, Multiply 4 to (3) and subtract (1) from it,

4a + 4b + 4c =76

4a +2b + c = 31

      2b + 3c = 45____(5)

Multiply 3 to (5) and subtract (4) from it,

6b + 9c = 135

6b + 8c =126

       c = 9

Substitute c= 9 in (5) we get,

2b + 3(9) = 45

⇒ b = 9

Now , substitute b = 9, c = 9 in (3) we get,

a + 9 + 9 = 19

⇒ a = 1

Required quadratic function is :

y = x² + 9x + 9  

Therefore, for the quadratic function y = ax² + bx + c , for which graph passes through the points (2, 31), (3 , 45) ,(1, 19) is given by y =x² + 9x + 9.
