Divide 3.5 × 108 by 6.6 × 104 and write the answer in scientific notation.

5.50699301 x 10 power of -1

Step-by-step explanation:

3.5 x 108 = 378

6.6 x 104 = 686.4

378/686.4 = 0.550699301

0.550699301 = 5.50699301 x 10 power of -1

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.
