A quality control consultant is to select 6 of these workers for in-depth interviews. Suppose the selection is made in such a way that any particular group of 6 workers has the same chance of being selected as does any other group (drawing 6 slips without replacement from among 45). a. How many selections result in all 6 workers coming from the day shift

Answers

Answer:

38760 selections result in all 6 workers coming from the day shift.

Step-by-step explanation:

The order in which the workers are chosen is not important, which means that we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

a. How many selections result in all 6 workers coming from the day shift:

20 workers are employed on the day shift, so this is a combination of 6 from a set of 20.

[tex]C_{20,6} = \frac{20!}{6!(20-6)!} = 38760[/tex]

38760 selections result in all 6 workers coming from the day shift.

The owner of a local nightclub has recently surveyed a random sample of 300 customers of the club. She would now like to determine whether or not the mean age of her customers is over 35. If so, she plans to alter the entertainment to appeal to an older crowd. If not, no entertainment changes will be made. Suppose she found that the sample mean was 35.5 years and population standard deviation was 5 years. What is the p-value associated with the test statistic

Answers

Answer:

0.0416

Step-by-step explanation:

Given :

Sample size, n = 300

Sample mean, x = 35.5

Population mean, m = 35

Standard deviation, s = 5

The test statistic :

Zstatistic = (x - m) / s/sqrt(n)

Zstatistic = (35.5 - 35) / 5/sqrt(300)

Zstatistic = 0.5 / 0.2886751

Zstatistic = 1.732

Using the p value calculator from Zstatistic :

One tailed P value at 95% confidence interval is : 0.0416

Write 13 1/5 as a decimal. ​

Answers

Answer:

13.2

Step-by-step explanation:

The Fraction 13 1/5 as a decimal is 13.2.

To write 13 1/5 as a decimal, we can divide the fraction part by the denominator:

1 divided by 5 = 0.2

Then, we add the whole number part to the decimal part:

= 13 + 0.2

= 13.2

Therefore, 13 1/5 as a decimal is 13.2.

Color blindness is an inherited characteristic that is more common in males than females. Let F represent female, and C represent red-green color blindness.

P(C) = 0.039 P(F and C) = 0.004 P(F or C) = 0.548



2. Use the Addition Rule or the "OR" formula for probability, substitute the values given, and solve for the probability of a Female.

P(F or C) = P(F) + P(C) - P(F and C)

Answers

Answer:

0.513 = 51.3% probability of being a female.

Step-by-step explanation:

We are given the following formula:

[tex]P(F \cup C) = P(F) + P(C) - P(F \cap C)[/tex]

In which:

Event F: Female

Event C: Red-green color blindness.

Probability of a Female

We have to find P(F), which is given by:

[tex]P(F) = P(F \cup C) + P(F \cap C) - P(C)[/tex]

We are given by:

[tex]P(C) = 0.039, P(F \cap C) = 0.004, P(F \cup C) = 0.548[/tex]

So

[tex]P(F) = P(F \cup C) + P(F \cap C) - P(C) = 0.548 + 0.004 - 0.039 = 0.513[/tex]

0.513 = 51.3% probability of being a female.

In which 45300 is the current number of miles driven and 143 is the amount of miles she drives each day.

b) 47,016 miles.

Step-by-step explanation:

Question a:

Every day when commuting to and from work, Stefanie drives her car a total of 143 miles for 2.5 hours. Her car already has 45,300 miles on it.

So, after x days of work, the amount of miles driven will be given by

[tex]f(x) = 45300 + 143x[/tex]

In which 45300 is the current number of miles driven and 143 is the amount of miles she drives each day.

Question b:

A diagnostic test for a disease is such that it (correctly) detects the disease in 90% of the individuals who actually have the disease. Also, if a person does not have the disease, the test will report that he or she does not have it with probability 0.9. Only 1% of the population has the disease in question. If a person is chosen at random from the population and the diagnostic test indicates that she has the disease, what is the conditional probability that she does, in fact, have the disease

Answers

Answer:

8.33% probability that she does, in fact, have the disease

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Positive test

Event B: Has the disease

Probability of a positive test:

10% of 100-1 = 99%

90% of 1%

So

[tex]P(A) = 0.1*0.99 + 0.9*0.01 = 0.108[/tex]

Positive test and having the disease:

90% of 1%

[tex]P(A \cap B) = 0.9*0.01 = 0.009[/tex]

What is the conditional probability that she does, in fact, have the disease

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.009}{0.108} = 0.0833[/tex]

8.33% probability that she does, in fact, have the disease

A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 666 centimeters per minute. After 202020 minutes, the water level is 220220220 centimeters.

Answers

Answer:

y = mx + b

slope(m) = 6

(20,220)....x = 20 and y = 220

now sub and find b, the y int

220 = 6(20) + b

220 = 120 + b

220 - 120 = b

100 = b

so ur equation is : y = 6x + 100

to graph :

y = 6x + 100.....u have a slope of 6....u have a y int of 100 or (0,100)...

I would say plot (0,100) and since ur slope is 6, go up 6 and to the right 1...but that is not to helpful because ur graph is not in intervals of 1.

So we will find some points on ur line.

y = 6x + 100....when x = 5

y = 6(5) + 100

y = 30 + 100

y = 130....so another point on ur line is (5,130)

y = 6x + 100...subbing in 10 for x

y = 6(10) + 100

y = 60 + 100

y = 160....another point is (10,160)

keep finding points this way...here are some more...

The 3rd term of an arithinetic progression is-9
and the 7th term is -29. Find the 10th term of the
progression.​

Answers

Answer:

-64

Step-by-step explanation:

The computation of the 10th term of the progression is shown below:

The 3rd term is -9

A_n = a + (n - 1)d

-9 = a + (3 - 1)d

-9 = a + 2d

-9 - 2d = a

Now the 7th term is -29

A_n = a + (n - 1)d

-29 = a + (7 - 1)d

-29 = a + 6d

Put the a value to the above equation

-29 = -9 - 2d + 6d

-29 + 9 = 4d

-20 = 4d

d = -5

Now

-9 - 2d = a

-9 - 2(-5) = a

-9 - 10 = a

a = -19

Now finally the 10th term of the progression is

= a + (n - 1)d

= -19 + (10- 1)-5

= -19 -45

= -64
