I need answers plz
I don't get it !!

i did the first 5 for you with explanation. try doing the rest so you'll understand better :)

1) mean:

median:

*arrange the numbers in ascending order and choose the number at the centre

2, 2, 3, 5, 5, 5, 6

= 5

mode:

*the number that occurs most often

= 5

range:

*highest value - lowest value

= 6-2

=4

2) mean:

median

10, 10, 12, 12, 15, 22, 24

=12

mode = 10 and 12

range = 24-10

= 14

3) mean:

median:

5, 9, 13, 14, 17, 20

*since there are 2 numbers at the centre, you need to add both numbers and divide it by 2 to get the median

mode:

no mode as all number occurs once only

range = 20-5

= 15

4) mean:

median:

13, 15, 16, 18, 21, 25

mode:

no mode

range = 25-13

= 12

5) mean:

median:

10, 12, 17, 18, 20, 25, 31

= 18

mode:

= no mode

range = 31-10

= 21

step-by-step explanation:

where is the questions

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
