Answer:

x=1

Step-by-step explanation:

5 − 3 x = x + 1

Move all terms containing x to the left side of the equation.

5 − 4 x = 1

Move all terms not containing x to the right side of the equation. − 4 x = − 4

Divide each term by − 4 and simplify.

x = 1

Answer:

No, there is not sufficient evidence to support the claim that the bags are underfilled

Step-by-step explanation:

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 434 gram setting.

This means that the null hypothesis is:

$H_{0}: \mu = 434$

It is believed that the machine is underfilling the bags.

This means that the alternate hypothesis is:

$H_{a}: \mu < 434$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

434 is tested at the null hypothesis:

This means that $\mu = 434$

A 9 bag sample had a mean of 431 grams with a variance of 144.

This means that $X = 431, n = 9, \sigma = \sqrt{144} = 12$

Value of the test-statistic:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{431 - 434}{\frac{12}{\sqrt{9}}}$

$z = -0.75$

P-value of the test:

The pvalue of the test is the pvalue of z = -0.75, which is 0.2266

0.2266 > 0.01, which means that there is not sufficient evidence to support the claim that the bags are underfilled.

Answer:

1 meter/10 millimeters is not a valid conversion factor.

Step-by-step explanation:

Because 10 millimeters (mm) is = to 1 centimeter (cm). This answer is obviously the only logical explanation. Contributing to the fact that 1 meter is equal to 100 centimeters and dividing that by 10 would make it 0.1 meters = 10 centimeters and 0.1 Meters = 100 Millimeters so that is clearly wrong that is why 1 meter/ 10 millimeters is not a valid conversion factor.

Company B Loses $1,575 for every employee who quit before 90days, What what is the total amount the company will lose if 2 emplo

Sergeu [11.5K]

Answer: The total amount is $4,725.

Step-by-step explanation:

1. Based on the information given in the problem, when an employee quit before 90 days, the company loses $1,575.

2. Then, the number of employees that quit before 90 days were:

$(2+1)=3$ employees

3. To calculate the total amount that the company will lose if these 3 employees quit before 90 days, you must multiply 3 employees by $1,575, as following:

$total=(3)(1,575dollars)\\total=4,725dollars$

4. The result is $4,725.
