Answer:

Option C

Step-by-step explanation:

We know that in a number line numbers all (rational preferably) would be marked on a line in a chronological order.

Mid point of A and B would be the average value of A and B.

Here given that mid point is 2 1/2

This implies average of A and B is 2 1/2

Or total of A and B should be 5

Out of 4 options let us check which gives total 5.

A) (2,3) .. Total is 5

B) (-4,9)..Total is again 5

C) (-4,8)..Total is not 5 but 4

D) (-0.75, 5,75) .. Total is 5

So out of these 4 options only C would not describe a situation where the midpoint between points A and B is 2 1/2

12 10,9,68,12<br> What is the most appropriate measure of center?
valentina_108 [34]

Answer: The most appropriate measure of center is the median.

Step-by-step explanation:

  • The measure of center generally represented by 1) mean 2) median 3) mode.
  • Mean is the best measure to represent the center of the data but when data have outliers it gets affected badly.
  • In that case, we use the Median as the best measure of center.

The given data is 12 10,9,68,12 .

As it can be seen that, the data have extreme value 68 ( called outliers).

In this case, we will use the Median as the best measure of center.

So, the most appropriate measure of center is the median.

Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?
jeka94

by Quadratic formula , x^2 + 20 = 2x , values of x are x = 1 \pm (1)i\sqrt{19}} . None of mentioned options are correct according to question!

<u>Step-by-step explanation:</u>

Here we have , expression  x2 + 20 = 2x or , x^2 + 20 = 2x .

We know that Quadratic formula is :

x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}

x^2 + 20 = 2x

⇒ x^2-2x+20=0

a=1\\b=-2\\c=20

Putting this value in equation x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a} :

⇒ x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}

⇒ x = \frac{-(-2) \pm \sqrt{(-2)^{2}-4(1)(20)}}{2(1)}

⇒ x = \frac{2 \pm \sqrt{4-80}}{2}

⇒ x = (\frac{2 \pm 2i\sqrt{19}}{2})

⇒ x = 1 \pm (1)i\sqrt{19}}

Therefore , by Quadratic formula , x^2 + 20 = 2x , values of x are x = 1 \pm (1)i\sqrt{19}} . None of mentioned options are correct according to question!
