Answer:

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

The number that produces an irrational number when multiplied by 0.4 is 3π. The correct option is A. $3\pi$

To determine which number produces an irrational number when multiplied by 0.4

First and foremost, 0.4 is a rational number.

A rational number is a number that is of the form $\frac{p}{q}$ where p and q are integers and q is not equal to 0.

0.4 can be written as $\frac{4}{10}$ or $\frac{2}{5}$ , hence, it is a rational number.

Now,

Any irrational number when multiplied by a rational number other than zero will also be irrational.

Therefore, we are to determine which of the given options is an irrational number.

For option A. 3π

π is an irrational number, therefore 3π is also an irrational number

For option B. 0.444...

0.444... can be expressed as 4/9, therefore it is a rational number

For option C. $\sqrt{9}$

$\sqrt{9}$ = 3, which can be expressed as 3/1, therefore it is a rational number

For option D. $\frac{2}{7}$

$\frac{2}{7}$ is a rational number

The only irrational number among the given options is 3π

Hence, the number that produces an irrational number when multiplied by 0.4 is 3π. The correct option is A. $3\pi$

Identify the type I error and the type II error that correspond to the given hypothesis. The percentage of adults who have a job

pychu [463]

Answer:

Type I error: The correct option is (C).

Type II error: The correct option is (D).

Step-by-step explanation:

The type-I-error is the probability of rejecting the null hypothesis when the null hypothesis is true.

The type-II-error is the probability of filing to reject the null hypothesis when in fact it is false.

The hypothesis in this problem can be defined as follows:

Null hypothesis (H₀): The percentage of adults who have a job is equal to 88%.

Alternate Hypothesis (Hₐ): The percentage of adults who have a job is different from 88%.

Type I error:

The type-I-error in this case will be committed when we conclude that the percentage of adults who have a job is different from 88% when in fact it is equal to 88%.

Type II error:

The type-II-error in this case will be committed when we conclude that the percentage of adults who have a job is equal to 88% when in fact it is different than 88%.
