Answer:
Sampling Error
Step-by-step explanation:
When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
That's strange. (3)(415) isn't exactly done with distributive property.
But let's try this:
3(415)
= 3(400+15)
= 1200 + 45
= 1245
So it's just breaking down the numbers...
But the answer is actually 1245.
Answer:
1/6
Step-by-step explanation:
Let X = amount of time (in minutes) a postal clerk spends with his or her customer. The time is known to have an exponential distribution with the average amount of time
X is a continuous random variable since time is measured. It is given that μ = 6 years. To do any calculations, you must know m, the decay parameter.
m = 1/μ = 1/6
So the decay rate is 1/6
There is no domain i believe
Answer:
Step-by-step explanation:
1/4(8y-12)
= 1/4(8y) - 1/4(12)
= 2y - 3
So it is not equal to 2y - 12
