Mean : The average of all the data in a set.

Median : The value in a set which is most close to the middle of a range.

Mode : The value which occures most frequently in a data set.

12,9,12,11,10,18,7,19,13,19

Mean = 13 (Average)

Median = 12 (Middle)

Mode = 12, 19 (most common)

What is the inverse of f(x)=3x-1
tatiyna

Answer:

$ \frac{(y + 1)}{3} $

Step-by-step explanation:

Call $ f(x) = y = 3x - 1 $

Now, $ y + 1 = 3x $

$ \implies \frac{y + 1}{3} = x $

This is the inverse of the given function.

You can cross - verify it by substituting a point, say, $ (1,3) $

We see that the point satisfies both the equations.

Given: A ABC<br> The measure of measure of
shepuryov [24]

Answer:

∠A = 90  

∠B = 30

∠C = 60

Step-by-step explanation:

Let ∠B = x

∠A = 3x

∠C = x + 30

Angle sum property of triangle: Sum of three angles of triangle is 180

x + 3x + x + 30 = 180   {Combine like terms}

         5x  + 30 = 180

                    5x = 180 - 30

                   5x = 150

                     x = 130/5

x = 30

∠A = 3*30 = 90

∠C = 30 + 30 = 60

The equation for the line that passes (-1,-2) and (4,3)
laila [671]
Find the slope and use one point to write the equation of a line (we’ll be using point-slope form). The slope is:
(3 - (-2) ) / (4 - (-1) ) = 1. Plug it into point slope form, y - y1 = m(x - x1), and we get y - 3 = 1(x - 4). If we want to get slope-intercept, distribute the 1, and solve for y: y = x - 1.
