The distance around tims rectangulr book is 48 centimeters the length of each longer side is 14 cm what is the length of each shorter side show your work for grade 2

Answers

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 = \frac{2+3+4+5+6+7+8+9}{8}=\frac{44}{8}=5.5

also, median= \frac{5+6}{2}=\frac{11}{2}=5.5, because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =   \frac{2+3+4+5+6}{5}=\frac{20}{5}=4

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.

r   = 2.65m

good luck!

let the length of each shorter side be x

length of longer side= x+14

2(x+14) + 2x = 48

2x + 28 + 2x = 48

4x + 28 = 48

4x = 48-28

4x = 20

x = 5

shorter side = 5cm

let the length of each shorter side be x

length of longer side= x+14

2(x+14) + 2x = 48

2x + 28 + 2x = 48

4x + 28 = 48

4x = 48-28

4x = 20

x = 5

shorter side = 5cm



Do you know the answer?
