Choice of Measures of Center and Variability - Qut. Level Question 8
The diagram shows the repairs performed on 2 types of cars.
Compare the car types using the median and the mean.
Roadsters
Bandits
0

Repairs per Vehicle
The median is the same for both car
types, but Bandits have the lower
mean.
Roadsters have the lower median,
but the mean is the same for both car
types.
The medians and the means are the
same for both car types.
Bandits have a lower median and a
lower mean than Roadsters.

i don't know

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8

step-by-step explanation:

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
