Answer:
An asteroid is a rock that orbits the sun, and meteors are rock debris that flies near the earth's exosphere and space. When they reach the exosphere they become meteoroids, since they are now in the Earth's atmosphere.
Answer:
6.5 minutes
Explanation:
We solve this question using this z-score formula.
z = (x-μ)/σ
where x is the raw score
μ is the population mean
σ is the population standard deviation
z = standard deviations above the mean = 0.43
x = 34 minutes
μ = 31.2 minutes
σ = unknown
n = 100
0.43 = (34 - 31.2)/ σ
0.43 = 2.8 / σ
Cross Multiply
0.43 × σ = 2.8
σ = 2.8/0.43
σ = 6.511627907
The standard deviation of the distribution is approximately 6.5 minutes
