Answer:
The probability is %13,5
Step-by-step explanation:
If it is a binomial distribution function than we can find a probability of earning less or more than 35000$ in this certain large city. Lets assume that p is probability of earning less than 35000$ and q is earning more than 35000$.:
p=0,45
q=0,55
So general formula of n families that earning less than 35000$ is:
Probability of 10 or less families out of 30 families that earning less than 35000$ is:
solving the polynomial we get the value -16
Step-by-step explanation:
We need to find the value of polynomial
Putting value of x as 1 and y=-2 and finding the value of polynomial.
So, solving the polynomial we get the value -16

Answer:
Step-by-step explanation:
Having drawn the line, Kendall must verify that the point P belongs to the line y = 2x-1 and then calculate the distance between A-P and verify if it is the closest to A or there is another one of the line
Having the point P(3,5) substitue x to verify y
y=2*(3)-1=6-1=5 (3,5)
Now if the angle formed by A and P is 90º it means that it is the closest point, otherwise that point must be found
and we found the distance PQ and QA
; ,
be the APQ triangle we must find <APQ through the cosine law (graph 2).
