Asmall country had a population of 8.4 x 10^8 in 2010. since then, the original population has doubled, and an additional 3.7 x 10^9 people have immigrated into the country. what is the population of the country now?

population now =  2 * 8.4 x 10^8 + 3.7 x 10^9

= 16.8 x 10^8 + 3.7 x 10^9

= 1.68 x10^9 + 3.7 x 10^9

= 5.38 x 10^9   (answer)

two data sets with the same median will not have the same varaibility

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
