In an attempt to be environmentally friendly, the city council decides that there must at least 18 trees on each block in thr city. A sample of 20 blocks was randomly surveyed, with these results (numbers of tree per blocks) 24, 17, 7 20 28 27 10 21 30 8 30 27 22 27 27 13 27 20 24 17 what is the sample mean number of trees per block

i dont know

step-by-step explanation:

stethere all not eveanp-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
