You would do 10x10x10x10x10, so it would be 100,000. So you're correct, nice job!
Answer:
c. 99.72% of the time the random variable assumes a value within plus or minus 1 standard deviation of its mean
Step-by-step explanation:
In a normal distribution, the shape is bell-shaped; this means it is symmetric.
The area under a normal distribution will always be equal to 1.
The mean, median and mode in a normal distribution are equal.
However, the data assumes values within 1 standard deviation above or below the mean 68% of the time, not 99.72% of the time. This is the characteristic that doesn't fit.
Answer:
The area is 48 square units.
Step-by-step explanation:
Split up the shape into 2 shapes a rectangle and a Triangle.

Answer:
F test
Step-by-step explanation:
Given that we want to study the average weight of children in the US. We collect a random sample of 345 first graders in three different US states
Since there are three samples representing three populations to check whether they have same average weight we have to use F test.
Two sample t test is wrong because here there are three samples.
Paired t test is done for the same item subject to two different tratments
Z test is done for comparing of a mean with population mean or proportion if the population standard deviation is known.
Hence here since the number of groups are more than two, only F test is best suited to determine whether there is a difference in the average student weight among the three states
12x^2 + 20x that is the answer
