Answer:
a. han did not divide -10x by 4
b. y intercept:5, x intercept:2
Step-by-step explanation:x
reason for b: you can graph y=-x+5 to get the y and x intercept

Okay, the easiest way (I personally) find surface area is to find the area of each face [L x W (OR H)] and then add all of the areas together.
Question 1) The Area of 1 of the faces is 4, because 2 x 2 is 4. Since there is 6 faces, do 6 times 4, or

Answer:
P(X = 0) = 0.1897
P(X = 1) = 0.3910
P(X = 2) = 0.3021
P(X = 3) = 0.1038
P(X = 4) = 0.0134
Step-by-step explanation:
For each owner, there are only two possible outcomes. Either they are insured against an earthquake, or they are not. The probability of a homeowner being insured against an earthquake is independent of other homeowners. So the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Suppose that in one metropolitan area, the chance a homeowner is insured against an earthquake is 0.34.
This means that
A sample of four homeowners are to be selected at random.
This means that
(a) Find the probability mass function of X. (Round your answers to four decimal places.)
The pmf is the probability of each outcome.
So
