Answer:
12
Step-by-step explanation:
To find the mean, add up all the numbers
18+ 19+ 19+ 4+14+ 8+ 22+ 3+ 1
108
Then divide by the number of terms
108/9 =
12
0.25 because there is 4 colours and obviously red is 0.75 percent and green and blue can’t be lower than 0.5 cuz that’s for yellow and there’s no 0%
(That makes no sense but it’s 0.25%)
Plug 4 in for every x
(3*4)-4=8
(4^2)-1=15 [(4^2) is 4*4]
(2*(4^2))-15= 15 [because of PEMDAS the exponent comes first and then multiply by 2 then subtract]
Perimeter is the sum of the lengths so add up all the sides from above
8+15+15=38
