How many times around the Earth is 3.7 trillion apples ?

crimeas [40]

Answer:

$7,663$ times around the Earth

Step-by-step explanation:

we know that

$1\ trillion=1,000,000,000,000=1*10^{12}$ (one million million)

The average size of an apple is approximately 8.3 cm

Convert to km

$8.3\ cm=8.3/100,000=8.3*10^{-5}\ km$

Multiply by 3.7 trillion apples

$3.7*10^{12}*8.3*10^{-5}=30.71*10^{7}=3.071*10^{8}\ km$

Divide by the circumference of earth (40,075 km)

$3.071*10^{8}/40,075=7,663\ times$

Answer:

A. Stratification

Step-by-step explanation:

Stratified random sampling is used when the researcher wants to highlight a specific subgroup within an entire population.

Stratification technique is mainly used to reduce the population differences and to increase the efficiency of the estimates. In this method the population is divided into a number of subgroups or strata.

Each strata should be so formed such that they are homogeneous as far as possible.
