3which pairs of numbers in scientific notation show one number that is about

20 times as great as the other number?

choose all that apply.

a

b

c

d

e

2.01 x 10' and 4.25 x 106

5.97 x 104 and 3.12 x 103

4.91 x 106 and 5.09 x 103

8.21 x 10-3 and 4.13 x 10-4

2.94 x 10-8 and 6.22 x 10-7

Step-by-step explanation:

Since,

Note : In every option we put greater number as numerator because 20 > 1.

If we take denominator greater than we can not obtained a number greater than 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.

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.
