Answer: mean= 16.9

Median= 14

Step-by-step explanation:

Mean= sum of data set/ number of data set

= 118/7 =16.9

Median- the middle number of a data set, to reflect the best measure of the centre, the data set should be arranged in an ascending order

12, 13, 13, 14, 21, 22,23...... 14 is the median

Can anyone explain me?

Alika [10]

Answer:

Step-by-step explanation:

a) (a + b)² = (a + b) * (a +b)

(a + b)³ = (a + b) * (a +b) * (a +b)

a²- b² = (a +b) (a - b)

Here (a + b) is common in all the three expressions

HCF = (a + b)

b) (x - 1) = (x - 1)

x² - 1 = (x - 1) * (x + 1)

(x³ - 1) = (x - 1) (x² + x + 1)

HCF = (x -1)

Find the slope of the line passing through the points (-2,5) and (3/2, 2).

sveticcg [70]

Answer:

The answer is

Step-by-step explanation:

The slope of the line passing through two points can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (-2,5) and (3/2, 2)

The slope is

<h3> $m = \frac{2 - 5}{ \frac{3}{2} + 2} \\ = - \frac{3}{ \frac{7}{2} } \\ = - 3 \div \frac{7}{2} \\ = - 3 \times \frac{2}{7}$ </h3>

We have the final answer as

Hope this helps you

Find the solutions to x² = 12.

Novosadov [1.4K]

Answer:

$x = \pm 2\sqrt3$

Step-by-step explanation:

Hello!

Let's use the square root property to solve this question

Solve:

$x^2 = 12$
$\sqrt{x^2} = \sqrt{12}$
$x = \pm\sqrt{12}$
$x = \pm \sqrt{4 * 3}$
$x = \pm 2\sqrt3$

The answer is option A: x = ±2√3
