A student stands at the entrance of her school and notes the colors of cars that enter the parking lot. The results are shown in the bar graph below. A histogram titled Cars Entering Parking Lot has car color on the x-axis and frequency on the y-axis. Blue, 7; black, 12; red, 5; white, 8; other, 9.

Which of the following is a true statement regarding the information shown in the bar graph?

Car color is a discrete variable.

Car color is a continuous variable.
Frequency is a discrete variable.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

the answer is 128
