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:
P = 0,0012 or P = 0.12 %
Step-by-step explanation:
We know for normal distribution that:
μ ± σ in that range we find 68.3 % of all values
μ ± 2σ ⇒ 95.5 % and
μ ± 3σ ⇒ 99.7 %
Fom problem statement
We have to find (approximately) % of cars that reamain in service between 71 and 83 months
65 + 6 = 71 ( μ + σ ) therefore 95.5 % of values are from 59 and up to 71 then by symmetry 95.5/2 = 49.75 of values will be above mean
Probability between 65 and 71 is 49.75 %
On the other hand 74 is a value for mean plus 1, 5 σ and
74 is the value limit for mean plus 1,5 σ and correspond to 49,85 (from z=0 or mean 65).
Then the pobabilty for 83 have to be bigger than 49.85 and smaller than 0,5 assume is 49.87
Finally the probability approximately for cars that remain in service between 71 and 83 months is : 0,4987 - 0.49.75
P = 0,0012 or P = 0.12 %
The answer is that x is equal to 2 and y is equal to 1
Answer:
42 ft squared
Step-by-step explanation:
First you must find the sides and heights of each of the shapes, for instance, the trapezoid, the rectangle, and the triangle. After you find the sides and height you would solve for the area using the three area formulas for each shape. Then once you have the three individual areas you would just add each answer together and get 42.
Formulas:
Trapezoid = 1/2(b1 + b2)h
Rectangle = b x h
Triangle = 1/2bh
Answer:
Therefore, the correct answer is 24,069,100.
Step-by-step explanation:
(6.91 x 10^4) = 6.91 x 10,000 (10 x 10 x 10 x 10) or 69,100.
(2.4 x 10^7) = 2.4 x 10,000,000 (10 x 10 x 10 x 10 x 10 x 10 x 10) or 24,000,000.
24,000,000 + 69,100 = 24,069,100
Therefore, the correct answer is 24,069,100.
Hope this helps! :D
