Inverse binomial distribution

Step-by-step explanation:

For each couple, there are only two possible outcomes. Either they agree to participate, or they do not. The probability of a couple agreeing to participate is independent of any other couple accepting. This means that we take the binomial distribution as a basis to solve this question.

However, we want to find the number of trials needed to have a number of successes, in this case 5, that is, we do not have a fixed number of trials, which means that the inverse binomial distribution is used, and is the answer to this question.

Step-by-step explanation:

112.5/15=7.5

[tex] \frac{112.5}{15} = 7.5[/tex] ✅

Option A⤵

[tex] \frac{15}{112.5} = 75 \\ ⇢ 0.1333 ≠75[/tex]

Option B⤵

[tex] \frac{112.5}{15} = 7.5 \\ ⇢  7.5 = 7.5[/tex]

Option C⤵

[tex] \frac{112.5}{15} = 75 \\ ⇢ 7.5 ≠75[/tex]

Option D⤵

[tex] \frac{15}{112.5} = 7.5 \\ ⇢ 0.1333 ≠7.5[/tex]

Hence, option B is correct.

Answer:

(a) [tex]f(n)= 900n -100[/tex]

(b) [tex]f(1) = 800[/tex]; [tex]f(n) = f(n-1) +900[/tex]   for [tex]n \ge 2[/tex]

Step-by-step explanation:

Given

[tex]f(1) = 800[/tex] --- first month

[tex]d = 900[/tex] --- difference in distance covered each month

Required

Find f(n)

To do this, we have:

[tex]a_n = a_1 +d(n -1)[/tex]

Where

[tex]a_1 = f(1) = 800[/tex]

This gives:

[tex]a_n = 800 +900(n -1)[/tex]

[tex]a_n = 800 + 900n - 900[/tex]

Collect like terms

[tex]a_n= 900n +800-900[/tex]

[tex]a_n= 900n -100[/tex]

So, we have:

[tex]f(n)= 900n -100[/tex]

As a recursion, we have:

[tex]f(1) = 800[/tex]

For every other month i.e. [tex]n \ge 2[/tex]

We have:

 [tex]f(n) = f(n-1) +900[/tex]  for [tex]n \ge 2[/tex]

Which means 900 miles plus distance covered in previous month

Answer:

a) By blocking on shaving brush size

Step-by-step explanation:

You block on the variable that the researchers think matters.

The experiment can BEST be conducted by blocking on shaving brush size

An experiment is designed to verify your hypothesis. If your theory is valid, every time a scientific experiment has been conducted, it has the potential to be true.

In this given experiment a technique is used to verify or disprove a theory, as well as assess the effectiveness or likelihood of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

Since, lather thickness and shaving brush size are related, changing the brush size could have an impact on the experiment's findings.

Therefore, The experiment can be best carried out by limiting the size of the shaving brush.

Answer:

Ronald ran at a speed of 14.26 km / h, while Khalil did so at a speed of 9.35 km / h.

Step-by-step explanation:

Given that Ronald and Khalil had a 400 meter race, and Ronald's time was 1 minute and 51 seconds, and Khalil's time was 2 minutes and 34 seconds, to determine how much faster was Ronald time the Khalil’s, the following calculation must be performed:

400 x 2.5 = 1000

60 x 60 = 3600

1.51 = 101 x 2.5 = 252.5

2.34 = 154 x 2.5 = 385

252.5 = 1000

3600 = X

3600 x 1000 / 252.5 = X

14,257.43 = X

385 = 1000

3600 = X

3600 x 1000/385 = X

9,350.65 = X

14,257.43 / 1000 = 14.26

9,350.65 / 1000 = 9.35

Thus, Ronald ran at a speed of 14.26 km / h, while Khalil did so at a speed of 9.35 km / h.

The probability that the car has the letters at the beginning and at the end is 1/15.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

The plate of car consists of two letters and four digits.

So, there are

= 6!/(4!*2!)

=(6 x 5 x 4!)/4! x 2

= 3 x 4

= 15 ways of arranging

Then, the probability that the car has the letters at the beginning and at the end is 1/15.

Step-by-step explanation:

The mean absolute deviation is 2.

'The mean absolute deviation is the mean distance between each data value and the mean of the data set.'

According to the given problem,

Mean of the given data set = 14

Absolute deviation of mean from each data point,

⇒ ( 9 - 14 ) = 5

⇒ ( 13 - 14 ) = 1

⇒ ( 14 - 14 ) = 0

⇒ ( 15 - 14 ) = 1

⇒ ( 15 - 14 ) = 1

⇒ ( 18 - 14 ) = 4

Mean absolute deviation = [tex]\frac{5+1+0+1+1+4}{6}[/tex]

                                          = [tex]\frac{12}{6}[/tex]

                                          = 2

Hence, we can conclude, the mean absolute deviation of the given data set is 2.

Step-by-step explanation:

Calorie consumption increases, and weight tends to increase slightly, but the relationship is not very strong.

To compare the daily calorie consumption of teachers to their weight, we can create a scatter plot of the given data, where the calorie consumption is plotted on the x-axis, and the weight is plotted on the y-axis.

Each point on the scatter plot represents a teacher, and the position of the point shows the teacher's calorie consumption and weight.

From the scatter plot, we can see that there is no clear pattern or trend between the calorie consumption and weight of the teachers. However, we can calculate the correlation coefficient between the two variables to quantify the strength and direction of the relationship.

Using a calculator or a spreadsheet program, we can find that the correlation coefficient between calorie consumption and weight is approximately 0.07, which indicates a weak positive correlation.

This means that as calorie consumption increases, weight tends to increase slightly, but the relationship is not very strong.

Answer:

  156 cm³

Step-by-step explanation:

The volume of any prism is the product of the base area and the height of the prism. Here, we can take the "base" to be the front face of the assembly, and its "height" to be the 3 cm distance between the front and back faces.

The front face area is the sum of the triangle area and the rectangle area.

  A = 1/2bh + LW

  A = (1/2)(10 cm)(4 cm) + (16 cm)(2 cm) = 52 cm²

Then the volume is ...

  V = Bh = (52 cm²)(3 cm) = 156 cm³ . . . . total volume of the two blocks
