Two conditions under which we can assume that the sample means follow a normal distribution are as follows:
1). If the sample size is large enough, n greater than or equals 30, the sampling distribution is approximately normal regardless of the shape of the population.
2). In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.

Answer:
x = - 3
Step-by-step explanation:
note that y = f(x)
locate y = 3 on the y- axis, go horizontally across to meet f(x) at (- 3, 3 ) , then
x = - 3 when f(x) = 3
Wow.... My brother Said that it took him a while to figure it out... but
add 110.25 and 55.45
you would get 165.70
multiply 165.70 by 4.5
then you would get 745.65
745.65 is your answer
4) (1,3)
This is because in order to keep the ordered pairs a function, x cannot repeat. 1 is the only x that has nor repeated. Hope this helps mate.
The answer is 2 buckets
Explain:
Tim picked 1 7/12 and Fred picked 4 2/3
These as improper fractions are 19/12
And 8/3
To make these have the same denominator you would times the 8/3 by 4 to give 32/12
Take these two away, Fred has 13 more apples.
And as we calculated it with there being 12 in each bucket there would be one full bucket but we would need another bucket for the apple left
So Fred picked 2 more buckets than Tim.
Hoped it makes sense and that I helped
