-2x + 5x -2x = 1 - 7
-4x + 5x = -5
-1x = -5
Then x = 5 not 6 :)

First of all, I collect like terms by rearranging coefficient with variables to one side plus
Rules;
1. When moving a coefficient (number ) the sign changes

You can work at most 20 hours next week. You need to earn at least $90 to cover your weekly expenses. Your dog walking job pays

Vadim26 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x ----> the dog walking hours

y ----> the car washing hours

we know that

The system of linear inequalities is equal to

$x+y\leq20$ -----> inequality A

$9x+10y\geq 90$ -----> inequality B

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

Two possible combinations of hours are

(10,10) and (0,9)

<em>Verify</em>

For (10,10)

Substitute the value of x and the value of y in both inequalities

<em>Inequality A</em>

$10+10\leq20$

$20\leq20$ -----> is true

<em>Inequality B</em>

$9(10)+10(10)\geq 90$

$190\geq 90$ ----> is true

therefore

(10,10) is a possible solution

For (0.9)

Substitute the value of x and the value of y in both inequalities

<em>Inequality A</em>

$0+9\leq20$

$9\leq20$ -----> is true

<em>Inequality B</em>

$9(0)+10(9)\geq 90$

$90\geq 90$ ----> is true

therefore

(0,9) is a possible solution

An insurance company estimates 45 percent of its claims have errors. The insurance company wants to estimate with 99 percent con

Answer:

We need a sample size of at least 657.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

The margin of error is given by:

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

45 percent of its claims have errors.

So $\pi = 0.45$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a pvalue of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

What sample size is needed if they wish to be within 5 percent of the actual

This is a sample size of at least n, in which n is found when M = 0.05.

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

$0.05 = 2.575\sqrt{\frac{0.45*0.55}{n}}$

$0.05\sqrt{n} = 1.28$

$\sqrt{n} = \frac{1.28}{0.05}$

$\sqrt{n} = 25.62$

$\sqrt{n}^{2} = (25.62)^{2}$

$n = 656.4$

We need a sample size of at least 657.
