Alandra's rectangular cake pan is 33\text{ cm}33 cm33, start text, space, c, m, end text by 23\text{ cm}23 cm23, start text, space, c, m, end text. She has enough batter to fill it to a depth of 3\text{ cm}3 cm3, start text, space, c, m, end text. Instead, Alandra wants to pour the batter into ice cream cones. She plans to fill each cone to a depth of 9\text{ cm}9 cm9, start text, space, c, m, end text with a diameter of 4\text{ cm}4 cm4, start text, space, c, m, end text.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
