The data modeled by the box plots represent the battery life of two different brands of batteries that were tested.

(a) What is the median value of each data set?

(b) What is the range for each data set?

(c) What is the interquartile range for each data
set?

(d) Which battery would you recommend to a
friend? Explain your choice.

1. 3

2. 4

3. 1

hope this ! have a great day.

i would need to see the dot plot : )

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
