Using conversions between odds and probabilities, we have that:

1. A) 4:21

2. 0.952 probability that a bag of flour passes inspection.

3. C) 1:39

4. 41:59.

5. 14:11

  • A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • An odd is given by a:b, in which <u>a is the number of successes and b is the number of failures</u>.

Item 1:

  • Probability of 0.16, thus, for 100 trials, <u>16 successes and 84 failures</u>, and the odd is:

16:84, which, simplifying by 4, is 4:21.

Item 2:

  • Odd of 20:1 means that 20 + 1 = <u>21 trials, there are 20 successes</u>, thus, the probability is:

p = \frac{20}{21} = 0.952

0.952 probability that a bag of flour passes inspection.

Item 3:

  • Probability of 0.025, thus, for 100 trials, <u>2.5 successes and 97.5 failures</u>, and the odd is:

2.5:97.5, which, simplifying by 2.5, is 1:39.

Item 4:

  • 59% probability that he will take the longest trail, thus 100 - 59 = 41% probability of him <u>not tanking the longest trail</u>, thus, the odds against him taking the longest trail is 41:59.

Item 5:

  • Probability of 0.56, thus, for 100 trials, <u>56 successes and 44 failures</u>, and the odd is:

56:44, which, simplifying by 4, is 14:11.

Find an equation for the inverse for each of the following.
IgorLugansk [536]

Answer:

  • <em>To solve these first swap x and y, solve for y and name it inverse function</em>

3. <u>y = -8x + 2</u>

  • x = -8y + 2
  • 8y = -x + 2
  • y = -x/8 + 2/8
  • y = -(18)x + 1/4

f⁻¹(x) = -(18)x + 1/4

-----------------------------------------

4.<u> y = (2/3)x - 5</u>

  • x = (2/3)y - 5
  • (2/3)y = x + 5
  • y = (3/2)x + (3/2)5
  • y = 1.5x + 7.5

f⁻¹(x) = 1.5x + 7.5

-----------------------------------------

5. <u>f(x) = 2x² - 6</u>

  • x = 2y² - 6
  • 2y² = x + 6
  • y² = 1/2x + 3
  • y = \sqrt{1/2x + 3}

f⁻¹(x) = \sqrt{1/2x + 3}

-----------------------------------------

6. <u>y = (x - 3)²</u>

  • x = (y - 3)²
  • \sqrt{x} = y - 3
  • y = 3 + \sqrt{x}

f⁻¹(x) = 3 +  \sqrt{x}

Because of a mistake in​ packaging, a case of 16 bottles of wine contained 9 of brand A and 7 of brand​ B, each without labels.
attashe74 [19]

Answer:

a) The probability that all five are brand​ A is 0.0288

b) The probability that exactly two bottles are brand​ A is 0.0288

c) The probability that none of the bottles is brand​ A is 0.0048

Step-by-step explanation:

We have 9 bottles of brand A and 7 bottles of brand B.

The total of bottles is 16.

a) The probability that all five bottles are brand​ A is given by:

P(5A)=\frac{9}{16} \frac{8}{15}\frac{7}{14}  \frac{6}{13} \frac{5}{12}=\frac{3}{104}=0.0288

b) Since we have 9 bottles of brand A we calculate the probability of picking two brand A bottles and the we calculate the probability of picking 3 brand B bottles:

P(2A3B)=\frac{9}{16} \frac{8}{15}\frac{7}{14}  \frac{6}{13} \frac{5}{12}=\frac{3}{104}=0.0288

c) The probability that none of the bottles is brand​ A is the same as picking 5 brand B bottles:

P(5B)=\frac{7}{16} \frac{6}{15}\frac{5}{14}  \frac{4}{13} \frac{3}{12}=\frac{1}{208}=0.0048
