Answer:
Not a function
Step-by-step explanation:
If it was a function there should be only one values for every x, in this case there is two values for x=0. Doesn't pass the vertical test.
Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.
Answer:
B: 6 to the 10th over 7 to the 6th
Step-by-step explanation:
(6^5 / 7^3)^2
We know that (a /b) ^c = a^c / b^c
(6^5)^2 / (7^3)^2
We know that a power to a power is the powers multiplied a^b^c = a^(b*c)
6^ (5*2)/ (7^(3*2))
6^10/(7^6)
Since the bases are not the same, there is nothing else we can do
Using the binomial distribution, it is found that there is a 0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- 7% of his customers buy a magazine, hence p = 0.07.
- A sample of 14 customers is taken, hence n = 14.
The probability that exactly 4 out of the first 14 customers buy a magazine is P(X = 4), hence:
0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.

Assuming that the 1.5 is in miles you must add 1.5 to 5.25 because you are looking for the previous elevation of the plane before it descended giving you an answer of 6.75 miles.
