Answer:

the mean is 13

Step-by-step explanation:

The way to find the mean of a set of numbers is to add all the numbers together and divide the sum by the number of numbers. so 11 + 11 + 12 + 13+ 13 + 13 + 14 + 14 + 15 + 15 + 16 + 16 + 18 / 13 = 13.9

Find the equation of the straight line which passes through each of the following pairs of points.

Tems11 [23]

Answer:

y = 3x + 1

Step-by-step explanation:

First, find slope:

$y2 - y1 / x2 - x1$

$10 - 4/ 3 - 1 = 6 / 2 = 3$

Then, put the equation into point-slope form using the point (1, 4):

$y - y1 = m(x - x1)$

where m is the slope

y - 4 = 3(x - 1)

If you want to put this into slope-intercept form, it would be

$y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1$

A polynomlal has been factored, as SHOWI Deluw.

Tom [10]

Answer:

The zeros are 6,-5,9

Step-by-step explanation:

The factored form of the polynomial is given as:

$f(x) = (x - 6)(x + 5)(x - 9)$

To find the zeros of this function, we set f(x)=0 and solve for x.

$(x - 6)(x + 5)(x - 9) = 0$

This implies that:

$(x - 6) = 0 \: or \: (x + 5) = 0 \: or \: (x - 9) = 0$

We solve for x to get:

$x = 6 \: or \: x = - 5 \: or \: x = 9$

The zeros are 6,-5,9
