8 / 6 3/10
= 8 * 10/63
=80/63
3 4/15 / 80/63
= 49/15 * 63/80
=<u>2.5725</u>

1. The manufacturer is taking a sample of her friends, which is most convenient to sample - Convenience sampling
2. The whole population is divided into different groups (strata) and random samples are drawn from each group - Stratified sampling
3. The population is divided into different clusters (here, communities) and whole clusters are surveyed - Cluster sampling
4. The samples are drawn at a fixed interval from the population list - Systematic sampling
5. The samples are randomly drawn from the population - Simple random sampling
Answer:
The other number is 3333.
Step-by-step explanation:
This is really easy, just subtract 1,938 from 5,271. (5271 - 1938 = 3333)
Answer:
5.099*10^14 m^2
Step-by-step explanation:
Earth is in thermal equilibrium. This means that our planet is radiating away exactly as much energy as it is receiving from the Sun. This "re-radiation" from the Earth is not visible because it its peak wavelength is in the infrared part of the spectrum. Even the coldest parts of the Earth are way above absolute zero, so every square meter of Earth’s surface is radiating this energy out to space. Using the same radius given in step 2 above, and the formula for the area of a sphere, calculate the surface area of the Earth.
(The radius of the Earth is 6,370,000 meters.)
The earth is spherical in shape , so we use the formula for finding the surface area of a sphere
Surface Area=
S.A=4*3.14*6,370,000^2
S.A=4*pi*40576900000000
S.A=5.099*10^14m^2
Man occupies about one-eighth of the earth.
Answer:
~48$
Step-by-step explanation:
0.47/25=0.0188
0.0188×211=3.9
