Suppose that a Coke/Pepsi survey was conducted of 40 randomly selected individuals from Gainesville. Thirty people selected Coke

. Which of the following statements correctly describes how the confidence interval for the population proportion of people that prefer Coke should be computed?
a. There are not 15 successes and 15 failures. A confidence interval can not be done.
b. There are not 15 successes and 15 failures. A confidence interval can be computed by adding 2 successes and 2 failures.
c. There are not 15 successes and 15 failures. A confidence interval can be computed by adding 4 successes and 5 failures.
d. There are at least 15 successes and 15 failures. A large sample confidence interval for the population proportion can be computed with no additional value.

Find a linear inequality with the following solution set. Each grid line represents one unit. [asy] size(200); fill((-2,-5)--(5,
kykrilka [37]

The linear inequality of the graph is: -x + 2y + 1 > 0

<h3>How to determine the linear inequality?</h3>

First, we calculate the slope of the dashed line using:

m = \frac{y_2 - y_1}{x_2 - x_1}

Two points on the graph are:

(1, 0) and (3, 1)

The slope (m) is:

m = \frac{1 - 0}{3 - 1}

This gives

m = 0.5

The equation of the line is calculated as:

y = m(x -x_1) + y_1

So, we have;

y = 0.5(x -1) + 0

This gives

y = 0.5x -0.5

Multiply through by 2

2y = x - 1

Now, we convert the equation to an inequality.

The line on the graph is a dashed line. This means that the inequality is either > or <.

Also, the upper region of the graph that is shaded means that the inequality  is >.

So, the equation becomes

2y > x - 1

Rewrite as:

-x + 2y + 1 > 0

So, the linear inequality is: -x + 2y + 1 > 0

Suppose b is any integer. If b mod 12 = 5, then 7b mod 12
Rzqust [24]

The result follows directly from properties of modular arithmetic:

b\equiv5\pmod{12}\implies 7b\equiv35\equiv-1\equiv\boxed{11}\pmod{12}

That is,

b\equiv5\pmod{12}

means we can write b=12n+5 for some integer n. Then

7b=7(12n+5)=12(7n)+35

and taken mod 12, the first term goes away, so

7b\equiv35\pmod{12}

etc
