Guybrush owns an island monkey preserve which has a length of 2x + 1 units and a width of x – 4 units. If the island is 1,586 square units in size, what are the dimensions of the island? A. 30 units by 30 units B. 30 units by 26.5 units C. 13 units by 122 units D. 61 units by 26 units

d

Step-by-step explanation:

61-1/2=30

30-4=26

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.
