The answer is the first one.
Knowing that population density is like a rate, people per a given area, you would take the amount of people and divide by the area.
3.11E7/7.69E6 = 4.02 people per km squared.
Also the “E” is another way to write times 10 to a power and I recommend using that notation when plugging it into a calculator.
Answer:
A. No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.
Step-by-step explanation:
No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means. The central limit theorem says that if we take a large sample (i.e., a sample of size n > 30) of any distribution with finite mean
and standard deviation
, then, the sample average is approximately normally distributed with mean
and variance
.
Answer:
11
Step-by-step explanation:
Just make your dot plot so that the amount of dots corresponding to the number is the amount of times the number shows in the box. :)
We are given that the insect can lift 1.182 x 10^3 times
it's own weight. Say that w is weight, so the lift is:
lift = 1.182 x 10^3 * w
Assuming that your body weight is 60 kg, therefore you
can lift:
lift = 1.182 x 10^3 * 60 kg = 70,920 kg
