Write a problem that includes multiplying decimals. explain how you know where to place the decimal in the prouduct

3.6 x 3.4.

6 times 4 is 24 so carry the 2. next 4 times 3 is 12 then add the so 14.

Next you do the left side; 3 times 3 is 9.. then 3 times 6 is equals 18.  

Now u should have 144 on top and 189 you add those; which equals 333. In each number (3.6 and 3.4); the decimal moved over once so 1 times 2 = 2

so move the decimal over twice and the answer would be 3.33

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.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
