Linear inequalities with two variables have infinitely many ordered pair solutions, which can be graphed by shading in the appropriate half of a rectangular coordinate plane. To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality.

An Infinite Number of solutions is the answer! LMK if you have any more questions, and have a nice day/evening.

You are renting a surfboard for the day. The surfboard rental fee is $25 with an additional charge of $7 per hour. You have at m

o-na [289]

Initial fee: $25

Per hour fee: $7

Your budget: $60

x = # of hours you can rent the surfboard

$25 + $7x ≤ $60

Subtract $25 from both sides.

$7x ≤ $35

Divide both sides by $7

x ≤ 5

You can rent the surfboard for less than or equal to 5 hours.

6. Eduardo Is thinking of a non-unit fraction with a single digit denominator

netineya [11]

Answer:

The fraction is $\frac{1}{4}$ .

Step-by-step explanation:

Eduardo Is thinking of a non-unit fraction with a single-digit denominator.

Assuming the fraction to be $\frac{1}{x}$ .

When Eduardo multiplies his fraction by 5 he gets a mixed number and when he multiplies his fraction by 3 he can simplify the answer.

Therefore, the fraction chosen by Eduardo will be $\frac{1}{x}$ , where x is between 5 and 3.

So, the fraction is $\frac{1}{4}$ .

Again, when he multiplies his fraction by 4 he gets $(\frac{1}{4} \times 4) = 1$ which is a whole number. (Answer)

According to data from the 2010 United States Census, 71.6% of the total United States population was over the age of 20. Suppos

Luden [163]

Answer:

Mean is 0.6.

Standard deviation is 0.059

Step-by-step explanation:

The first step is finding the sample proportion p.

Suppose Maria, a researcher, takes a random sample of 70 Americans and finds that 42 are over the age of 20.

This means that $p = \frac{42}{70} = 0.6$

What are the mean and standard deviation of the sampling distribution of p?

Mean:

The mean of a proportion is the same as the proportion. So the mean is 0.6

Standard deviation:

Proportion p in a sample of size n. The standard deviation is:

$s = \sqrt{\frac{p(1-p)}{n}}$

Sample size 70, so:

$s = \sqrt{\frac{0.6*0.4}{70}} = 0.059$
