Answer:
A. linear
Step-by-step explanation:
A linear model is the best-fitting regression model for the data plot because for similar variations in x values, the variation in y values are also similar, that is, if you take points (x1, y1), (x2, y2) and (x3, y3) the y1 - y2 is similar to y2 - y3, when x2 - x1 is also similar to x3 - x2.
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.

A. Here's a fifth degree polynomial,
f(x) = x⁵ + 4x⁴ - 14x² + 9
It's in standard form, each term a constant coefficient times a whole number power of x (including the constant, which we can think of as the coefficient on x⁰=1), with the terms sorted from highest degree (highest power on x) to lowest.
B. The closure of addition wrt polynomials just means when we add two polynomials we get another polynomial.
f(x) = x⁵ + 4x⁴ - 14x² + 9
g(x) = -2x⁴ + x
f(x)+g(x) = x⁵ + 2x⁴ - 14x² + x + 9
We added two polynomials, we got another one, that's all closure is.
