Answer:

The independent variable is "x."

The dependent variable is "y."

Step-by-step explanation:

An independent variable is a variable that does not depend on an event. It is independent of another variable. It does not change as a result of another variable. It remains constant as it is controlled. It is used to measure the dependent variable.

A dependent variable varies. It depends on the independent variable for its outcome. It can yield various results depending on how the independent variable is changed. "y" in our example will change its value because of the value placed on "x." The dependent variable is the variable that is being measured or tested in an experiment. For example, the sales revenue of goods is a dependent variable of another independent variable like price and a constant (quantity).

Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

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:

There are 12 customers, hence n = 12.

The probability of any of them making a purchase is of p = 0.4.

The probability that more than 7 will make a purchase is given by:

P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).

Hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 8) = C_{12,8}.(0.4)^{8}.(0.6)^{4} = 0.042$

$P(X = 9) = C_{12,9}.(0.4)^{9}.(0.6)^{3} = 0.012$

$P(X = 10) = C_{12,10}.(0.4)^{10}.(0.6)^{2} = 0.02$

$P(X = 11) = C_{12,11}.(0.4)^{11}.(0.6)^{1} \approx 0$

$P(X = 12) = C_{12,12}.(0.4)^{12}.(0.6)^{0} \approx 0$

Then:

P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.

0.056 = 5.6% probability that more than 7 will make a purchase.

Plsss help me need help

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

a. 9(4x - 3y - $\frac{2}{3}$ )

36x - 27y - ( $\frac{9}{1}$ * $\frac{2}{3}$ )

36x - 27y - $\frac{18}{3}$

36x - 27y - 6

b. -2 (-6x + 3y - 1)

12x - 6y + 2

c. $\frac{1}{5}$ (20y - 4x - 13)

4y - $\frac{4}{5}$ x - $\frac{13}{5}$

- $\frac{4}{5}$ x + 4y - $\frac{13}{5}$

d. 8(-x - $\frac{1}{2}$ )

-8x - 4

e. -8(-x - $\frac{3}{4}$ y + $\frac{7}{2}$ )

8x + $\frac{24}{4}$ y - $\frac{56}{2}$

8x + 6y - 28

Hope that helps!

Find y<br> I will give brainlist

Arada [10]

Ok this one is easier than you might think. The line equals 180 degrees since it is a straight line, therefore you need to do 180-27 to get what y equals. Y=153
