Explanation:

The x coordinates are 3 and -2

The x coordinate of the midpoint is 0.5

--------------

The steps are the same idea for the y coordinates

The y coordinate of the midpoint is 7

--------------

Overall, the midpoint is located at (0.5, 7)

You can confirm this by letting

A = (3,8)

B = (0.5, 7)

C = (-2,6)

Then use the distance formula to see that AB = BC

Step-by-step explanation:

(B) 12 Inches is the answer because perimeter (P) =4l =4×3=12

The solution set for the inequality expression is (-∞, -6)

Inequality are expressions that does not involve an equality sign.

Given the following parameters

-3x + 3 > -21

Subtract 3 from both sides

-3x + 3 - 3 > 21 - 3

-3x > 18

Divide both sides by -3

-3x/-3 < 18/-3

x < -6

Hence the solution set for the inequality expression is (-∞, -6)

The distance of the boat from its destination depends on

So with these factors, the distance of the boat from its distance can be calculated.

The distance of the boat from the destination currently is 63 miles

Speed of the boat is 10 miles / hr

Let c be the speed of the river current and

h be the number of hours to reach a particular destination

So, the formula to find the distance of the boat from destination is given by

D = 63 - h(10 - c)

We need to find the formula for boat's distance from its destination after 3 hours

Thus h = 3 hrs

Let us substitute h in above equation, Then

D = 63 - 3(10 - c)

D = 63 - 30 - 3c

D = 33 - 3c

which is the formula for the boat's distance from its destination after 3 hours.

Given that the average score on a lab report is 87 points. All students score within 1.8 points of the average.

Let 'x' be the score of student. The maximum and minimum score of a student lies within 1.8 points of the average.

Then, maximum score of a student, x = 87+1.8

and minimum score of a student, x = 87-1.8

Combining these two equations, we get, x = 87 ±1.8

Given that

To find

So, according to the question

We have,

        ∵ [tex]average = \frac{sum\;of\;terms}{number\;of\;terms}[/tex]

        ∴ Total points gained by Larry in 4 games

                         = (average points in 4 games) × 4

                         =  23 × 4

                         =  92 points.

Let's assume Larry scored x points in the 5th match to have an average of 25 PPG.

So, we can say that

        Larry's average in 5 games = [tex]\frac{total\;points\; in\; 5\;games}{5}[/tex]

                                                 25 = [tex]\frac{92+x}{5}[/tex]

                                           25 × 5 = 92 + x

                                                125 = 92 + x

                                                    x = 125 - 92

Congruent line segments are geometrical figures in one dimension with identical dimensions. In terms of congruent lines, the word "congruent" refers to the equality of the two line segments. When two lines are the same length, they are said to be congruent. Superimposable figures that entirely enclose each other when stacked one atop the other are congruent segments.

The statistical measures for the 10-day vacation are given as follows:

a) Mean: $2470.

b) Standard deviation: $189.74.

c) Variance: $²36,001.

To find the mean for n days, we take the mean amount for the distribution in a single day and multiply by n.

Hence, considering that the mean for a single day is of $247:

247 x 10 = $2470.

To find the standard deviation for n days, we take the standard deviation for a single day and multiply by the square root n.

Hence, considering that the standard deviation for a single day is of $60, we have that:

60 x sqrt(10) = $189.74.

For any distribution, the variance is the square of the standard deviation, hence:

($189.74)² = $²36,001.

Using the monthly payment formula, it is found that the best plan is given by:

The monthly credit card payment would be $238.37, which is lower than the monthly payment on the bank loan.

It is given by:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

In which:

For the simple interest payment method, the parameters are given as follows:

r = 0.06, n = 3 x 12 = 36, P = 11000, r/12 = 0.06/12 = 0.005.

Hence:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

[tex]A = 11000(0.005)\frac{(1.005)^{36}}{(1.005)^{36} - 1}[/tex]

A = 334.64.

For the credit card payment method, the parameters are given as follows:

r = 0.16, n = 6 x 12 = 72, P = 11000, r/12 = 0.16/12 = 0.0133.

Hence:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

[tex]A = 11000(0.0133)\frac{(1.0133)^{72}}{(1.0133)^{72} - 1}[/tex]

A = 238.37.
