The number of cell phones sold by a store on consecutive days of a month is shown below:
25, 13, 16, 34, 13, 31, 16, 34, 19, 22, 13, 28, 19, 16, 22, 16, 13, 16, 13, 16
sam created the following incorrect dot plot to represent the data:
what should sam do to make the dot plot correct?
put another dot on 13
put another dot on 16
delete one dot on 22
delete one dot on 34

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
