It's is a bell shaped histogram
Step-by-step explanation:
This is a binomial distribution problem.
A binomial distribution is a distribution whose experiment has two possible outcomes, a success and failure. The outcomes of the experiment do not depend on each other.
For n trials in a binomial distribution, the probability of getting success:
P(X=x) = n!/[(n-x)!x!] × p^x × q^(n-x)
Where p = success
q = failure
n = 8, p= 40% = 0.4
q = 1-0.4 = 0.6
See attachment for workings and histogram diagram.
From the diagram, the shape of the histogram is bell shaped. It is also known as a normal distribution.
Answer:
There are two main types of correlation coefficients: Pearson's product moment correlation coefficient and Spearman's rank correlation coefficient. The correct usage of correlation coefficient type depends on the types of variables being studied. We will focus on these two correlation types; other types are based on these and are often used when multiple variables are being considered.

Answer: 
Step-by-step explanation:
For this exercise it is important to remember that:
1. The word "difference" indicates subtraction (The result of a subtraction is called "difference").
2. The multiplication of signs:
For this case, according to the data given in the exercise, the records high temperature and the record low temperature are:
Therefore, if you want to find the difference in the record temperatures, you need to sutract them.
Then you get the following result:
644.4 rounded to the nearest one would be 644
Step-by-step explanation:
m < (CAB ) = m < ( c B A ).....
