Answer:

The mean is 9.5 and the median is 6.5.

Step-by-step explanation:

<em>To find the mean:</em>

Add all numbers given.

9+8+5+3+37+8+4+2= 76

Then divide by the amount of numbers (8).

76/8= 9.5

<em>To find the median:</em>

Re-arrange the order of the numbers from least to greatest.

2, 3, 4, 5, 8, 8, 9, 37

Count towards the middle. If there is no exact middle (like this equation), then take the two middle numbers and add them.

5+8= 13

After, divide by two since there are two numbers being added.

13/2= 6.5

Given the equation of a line: y = 3x - 7. Select the equation of the line PERPENDICULAR to this line
iogann1982 [59]

Answer:

The third option, y=(-1/3)x-7

Step-by-step explanation:

To find a line perpendicular to an equation, you find the negative reciprocal of the slope. For instance, if you have an equation y=4x+5, the negative reciprocal is y=(-1/4)x+5. That is the equation to find a line perpendicular to this.

If you want to find a line parallel to the equation y=4x+5, all you have to do is come up with another equation that has the same slope. So, y=4x+8 would be a line parallel to the equation y=4x+5.

Given the function ƒ(x) = 5x^2 − 9x + 18, find ƒ(3). A) ƒ(3) = 31 B) ƒ(3) = 36 C) ƒ(3) = 49 D) ƒ(3) = 85
kumpel [21]

Answer:

36

Step-by-step explanation:

ƒ(x) = 5x^2 − 9x + 18,

Let x=3

ƒ(3) = 5*3^2 − 9*3 + 18,

      =5*9 - 27+18

        45 - 27+18

         36
