A group of students at a high school took a standardized test. The number of students who passed or failed the exam is broken down by gender in the following table. Determine whether gender and passing the test are independent by filling out the blanks in the sentence below, rounding all probabilities to the nearest thousandth.

Passed Failed
Male 17 6
Female 34 12

Since P(mail |fail)=____ and P(male)=, the two results are_ so the events are______

Answers

Answer 1

Answer:

Step-by-step explanation:

From the given information:

Passed Failed Total

Male 17 6 23

Female 34 12 46

Total 51 18 69

[tex]P(male | fail) = \dfrac{P(male \cap fail)}{ P(fail)}[/tex]

[tex]P(male | fail) = \dfrac{\dfrac{6}{69} }{\dfrac{18}{69}}[/tex]

[tex]P(male| fail) = \dfrac{1}{3}[/tex]

[tex]P(male | fail) = 0.333[/tex]

[tex]P(male) = \dfrac{23}{69}[/tex]

[tex]P(male) = \dfrac {1}{3}[/tex]

[tex]P(male) = 0.333[/tex]

The two results are equal:

So the events are dependent.

Ann Nguyen would like an installment loan for $5,750. Her bank will loan her the
money at 18% for 18 months. Her insurance company will loan her the money at
18% for 24 months. How much money will she save by choosing the smarter loan?

Answers

9514 1404 393

Answer:

$281.40

Step-by-step explanation:

A financial calculator tells you the payment for the 18-month loan is $361.46, so her total payback amount is $6506.28.

Similarly, the payment for the 24-month loan is $282.82, and the total amount repaid is 6787.68.

The shorter-term loan costs less by ...

$6787.68 -6506.28 = $281.40

Ann can save $281.40 by choosing the shorter-term loan.

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?

Answers

Answer:

A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.

Step-by-step explanation:

To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.

For questions 9 and 11, solve for the remaining angles.

Answers

Answer:

‹A = 141°

‹B = 28°

‹C = 11°

*These angles are rounded to the nearest whole*

Step-by-step explanation:

Because you are only given sides you can find an individual angle measures with the inverse law of cosines.

Remember the side opposite of the angle corresponds to that angle.

a² = b² + c² - 2bc cos(A) →

A = cos⁻¹ (a² - b² - c² / -2bc)

b² = a² + c² - 2ac cos(B) →

B = cos⁻¹ (b² - a² - c² / -2ac)

c² = a² + b² - 2ab cos(C) →

C = cos⁻¹ (c² - a² - b² / -2ab)
