Which one of the following options correctly
calculates the mean?

(2+3+6 +7+14)-4

(199+237 +361)2

(18+ 27 - 2 + 14-16):5

(1001+ 1012 +990-987):10

Hey there!

The answer is C.

To calculate the mean, you add all the values together then divide by the amount of values you have.

Since we are adding 5 numbers together, we divide it by 5.

Don't let the subtraction signs confuse you, it just means that some of the numbers are negative.

Hope this helps!

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
