Answer:

7.3

Step-by-step explanation:

The mean is the average of the data set. This can be found by dividing the number of numbers in the data set by the sum of all the numbers.

So firso first, we have to find the sum:

7+9+7+9+15+0+11+13+11+1=73

There are 10 numbers.

73/10=7.3

The mean is 7.3

Answer:

A. The graph is a line that goes through the points (9,0) and (0,6).

Step-by-step explanation:

Given

$4x + 6y = 36$

Required

Select the true options

$(a)\ (9,0)\ and\ (0,6)$

This implies that"

$(x_1,y_1)= (9,0)$

$(x_2,y_2)= (0,6)$

So, we have: $(x_1,y_1)= (9,0)$

$4x + 6y = 36$

$4 * 9 + 6 * 0 = 36 + 0 = 36$

So, we have: $(x_2,y_2)= (0,6)$

$4 * 0 + 6 * 6 = 0 + 36 = 36$

<em>Hence (a) is true.</em>

Factor 2m^3-12m^2+18m completely

Nina [5.8K]

Answer:

The answer is A.

Step-by-step explanation:

Firstly, you have to take out the common terms for this expression. In this expression, the common terms ard 2 and m :

$2 {m}^{3} - 12 {m}^{2} + 18m$

$= 2( {m}^{3} - 6 {m}^{2} + 9m)$

$= 2m( {m}^{2} - 6m + 9)$

Next you have to factorise the brackets :

${m}^{2} - 6m + 9$

$= {m}^{2} - 3m - 3m + 9$

$= m(m - 3) - 3(m - 3)$

$= (m - 3)(m - 3)$

$= {(m - 3)}^{2}$

So the final answer is :

$2m {(m - 2)}^{2}$
