The mean of 100 numerical observation is 51.18 what is the value of the sum of all 100 numbers
malfutka [58]
The "mean" is the same thing as the "average".

To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.

If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.

If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100.  So the big sum is 5,118.

Factor the following trinomials x2-18x+81
poizon [28]

Answer:

(x - 9)(x - 9)

Step-by-step explanation:

<em>Hey there!</em>

Well to factor,

x^2-18x+81

we need to figure out what times what equal 81 and adds together to get -18.

-9*-9 = 81

-9 + -9 = -18

x*x = x^2

Factored - (x - 9)(x - 9)

<em>Hope this helps :)</em>

HELP!! Which of these linear equations best describes the given model?
viktelen [127]

Option B:

The linear equation that best describes the model is y = 40x + 800.

Solution:

Take two points which exactly on the line.

Let the points are (0, 800) and (10, 1200).

x_1=0, y_1=800, x_2=10, y_2=1200

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{1200-800}{10-0}

$m=\frac{400}{10}

m = 40

y-intercept of the line is where the line crosses at y-axis.

y-intercept (b) = 800

Equation of a line:

y = mx + b

y = 40x + 800

The linear equation that best describes the model is y = 40x + 800.

Option B is the correct answer.
