Earth has a diameter of approximately 8,000 miles. If the circumference of a circle can be found using the formula C = πd, what
1 answer:
Answer: Circumference of Earth= 25120 miles
Step-by-step explanation:
Given: The circumference of a circle can be found using the formula , where d= diameter of the circle.
Earth's diameter = 8000 miles (approx)
The circumference of circle = [substitute values in formula]
The circumference of circle = 25120 miles (approx)
Hence, the circumference of Earth= 25120 miles (approx)

Answer:
101, 3, 0.025, 0.7416
Step-by-step explanation:
Given that a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.
As per central limit theorem we have
a) Mean of sample mean =
Std deviation of sample mean =
Mean = 101
Std dev =3.00
b)
c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.
