How will adding the value 75 affect the mean and median of the data set 1, 5, 7, 9 , 9, 10?
kenny6666 [7]
Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8

After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9

So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)

So it's C :The median increases less than the mean increases.

For the linear function f(x) = -2x+1 , find the following
Leya [2.2K]

Given:

The function is:

f(x)=-2x+1

To find:

a. Slope and Y-intercept.

b. Is the function increasing, decreasing, or constant, justify your answer.

c. Graph the function, label x, and y-intercepts.

Solution:

a. We have,

f(x)=-2x+1                  ...(i)

The slope intercept form of a line is:

y=mx+b                    ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

m=-2,b=1

Therefore, the slope of the line is -2 and the y-intercept is 1.

b. If the slope of a linear function is negative, then the function is decreasing.

If the slope of a linear function is positive, then the function is increasing.

If the slope of a linear function is 0, then the function is constant.

The slope of the linear function is negative.

Therefore, the function is decreasing.

c. We have,

f(x)=-2x+1

At x=0, we get

f(0)=-2(0)+1

f(0)=1

So, the y-intercept is at (0,1).

At f(x)=0, we get

0=-2x+1

2x=1

x=\dfrac{1}{2}

x=0.5

So, the x-intercept is at \left(0.5,0\right).

Plot the points (0,1), \left(0.5,0\right) and connect them by a straight line as shown below:
