Which net diagram represents this solid figure?

 The answer is the second optional figure. Image is attached herewith.

Step-by-step explanation:  We are given a picture of a solid with dimensions 2 units, 3 units and 5 units as shown in the figure. We are to select the correct net diagram for the solid from the four optional figures.

We can easily that if we open up the solid from all sides, it will look exactly same as the second optional figure. One may also try to do so with a piece of paper.

The solid and its net diagram is shown in the attached figure.

Thus, second option is correct.

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.

answer: 20
