If you had 454g of shrimp/sq ft in a tank with an 11 sq meter bottom area, how many total kilograms of shrimp do you have?

total weight of the shrimp = 53.7549 kg.

Step-by-step explanation:

Given,

Weight of shrimp = 454 g/sq meter

area of bottom of tank = 11 sq meter

By converting meter into ft,

    1 sq meter = 10.7639 sq feet

=> 11 sq meter = 11 x 10.7639 sq ft

                       = 118.4029 sq feet

So, the total area of the bottom of the tank = 118.4029 sq feet

According to question,

Weight of shrimp in 1 square ft = 454 g

so, the weight of shrimp in 118.4029 sq ft = 118.4029 x 454 g

                                                                     = 53754.9166 g

Since,  

                                        = 53.7549 kg

So, the total weight of the shrimp will be 53.7549 kg.

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.
