Use the following information for Questions 7 - 10. Last year two sections of probability and statistics were taught by an instructor. The first section had 20 students and the second had 30 students. Each student had to complete a project. The projects were randomly ordered before grading. Consider the first 15 graded projects. Question 7: Which type of probability distribution best describes the problem

To find the combined rate of all the individuals working together, you must add the individual rates.

When calculating the combined rate of individuals working together, you need to add up the individual rates. Each worker contributes their own rate of work or productivity, and by adding these rates together, you can determine the combined rate at which they are working collectively.

This allows you to assess the overall efficiency and output of the team or group. By summing up the individual rates, we have better understanding of the overall productivity and performance of the group.

Answer:

6.75 servings.

Step-by-step explanation:

The measure that is most affected by extremely large or small values in the data set is the range. The correct option is C

The range is calculated by subtracting the smallest value in the data set from the largest value in the data set. If there are extremely large or small values in the data set, the range will be skewed and not representative of the spread of the majority of the data.

The interquartile range (IQR) is less affected by extreme values because it only considers the middle 50% of the data, specifically the difference between the third quartile and the first quartile.

Answer: choice A 1/2

Step-by-step explanation:

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true.

so

1/3=2/3*p(B)

p(B)=1/2

Answer:

Time of Death = 2 : 49 : 45 AM

Step-by-step explanation:

The formula for Newton's Law of Cooling is written as follows:

dT/dt = - K(T - Ts)

where,

dT = change in temperature

dt = time interval

K = cooling constant

T = Final Temperature of object

Ts = Surrounding Temperature

First, we will use the data of cooling of body from 28°C to 27°C to find the cooling constant of the body:

dT = 27°C - 28°C = -1°C

dt = 1 hr = 3600 s

K = ?

T = 27°C

Ts = 22°C

Therefore,

-1 °C/3600 s = - K(27 °C - 22 °C)

K = 1 °C/(3600 s)(5 °C)

K = 5.55 x 10⁻⁵ /s

Now, we use data for cooling of body from 37 °C to 28 °C to find the time of death:

dT = 28°C - 37°C = -5°C

dt = ?

K = 5.55 x 10⁻⁵ /s

T = 28°C

Ts = 22°C

Therefore,

- 5 °C/dt = - (5.55 x 10⁻⁵ /s)(28 °C - 22 °C)

dt = 5 °C/(5.55 x 10⁻⁵ /s)(6 °C)

dt = 1.5 x 10⁴ s

dt = 4.17 h = 4 h 10 min 15 s

Therefor,

Time of Death = 7 : 00 : 00 AM - 4 : 10 : 15

Time of Death = 2 : 49 : 45 AM

Answer:

3.45

Step-by-step explanation:

Do long division to get your answer, but instead of division you can just multiply 15 x 3.45 and you'll get 51.75.

Answer:

The answer is 3.45.

Step-by-step explanation:

Let's first look only at the numerator: 5x^2 - 5

Consider this question: What do both terms have in common?

The answer is 5, both terms contain a 5, so we can factor it out.

5(x^2 - 1)

Now let's look at the denominator, considering the same question: 3x^2 + 3x

This time, both terms contain a 3 and an x.

3x(x^2 + 1)

Now we are here: [ 5(x^2 - 1) ] / [ 3x(x + 1) ]

In the numerator, the binomial factors out into (x + 1)(x - 1). There is also an (x + 1) in the denominator, so those to binomials cancel out. That leaves us with the following expression:

5(x - 1) / 3x

Correct Answer: C

Answer:

Cost for 25 songs: $23.50

Cost for s songs: .50(s) + 11

Step-by-step explanation:

To solve this problem, we can make an equation in slope-intercept form:

y = mx + b

y represents the total amount of $.

m represents the cost of each song downloaded, or $.50

x represents the number of songs, or 's'

b represents the $11, or the constant.

We have the equation:

y = .50(x) + 11

If Angel downloaded 25 songs, we have the equation:

y = .50(25) + 11

We get y = $23.50

Answer:

x= -3

Step-by-step explanation:

−2(8x−1)=5(1−3x)

Step 1: Simplify both sides of the equation.

−2(8x−1)=5(1−3x)

(−2)(8x)+(−2)(−1)=(5)(1)+(5)(−3x)(Distribute)

−16x+2=5+−15x

−16x+2=−15x+5

Step 2: Add 15x to both sides.

−16x+2+15x=−15x+5+15x

−x+2=5

Step 3: Subtract 2 from both sides.

−x+2−2=5−2

−x=3

Step 4: Divide both sides by -1.

Answer:

x = 9,   FG = 8

Step-by-step explanation:

The question depends on the relationship EF + FG = EG  (the two shorter segments add up to the long segment).

7 + 2(x - 5) = 3(x - 4)

7 + 2x - 10 = 3x - 12

-3 + 2x = 3x - 12

-3 = x - 12

9 = x

The length FG can be found by substituting 9 for x.

FG = 2(x - 5) = 2(9 - 5) = 2(4) = 8

Answer:

x should be 8 and FG should be 7

Step-by-step explanation:

Considering segment EF and FG look relatively the same in length, let's assume 2(x-5) = 7.

And assuming both segments are equal to 7, the total would be 14.

3x-12=14

add 12 to 14 which would get you 26

3x=26

divide 26 by 3

which would be 8.666 repeating which for the sake of this we'll round down to 8

check with 2(x-5)

2x-10=7

add 10 to 7

17/2 should equal 8.5 which we'll round down to 8

take this with a grain of salt as I don't know much about college math

Answer: Randomly assign the 1,200 students to 6 equal-sized groups. Then select one of the groups and place their names in the bin. Randomly select the winner from the bin.

Step-by-step explanation:

     First, let us see how many bins we will need in total.

1,200 students / 200 notecards per bin = 6 bins

     Now, the first two options do not give all students a fair chance of winning. They are not our answer.

     The last two have a different number of groups. Looking at the calculation we did earlier, we will need 6 equal-sized groups. This means our answer is the last option.

Given that g(x) =f(kx). The graph of function g is graph Z Because the graph a function g is the result of a horizontal compression applied to the graph of function F.

A graph can be described  as a pictorial representation or a diagram that represents data or values in an organized manner.

The graph of the function g(x) = f(kx) is obtained from the graph of f(x) by a horizontal compression or stretching, depending on the value of k.

In conclusion, If k is greater than 1, then the graph of g(x) is obtained from the graph of f(x) by a horizontal compression.

The mean monthly rainfall, Rounded to the nearest thousandth, is 2.520 inches.

To determine the mean monthly rainfall, we need to calculate the average of the rainfall values provided in the table. Here is the table:

| Month | Rainfall (in inches) |

|-------|----------------|

| January   | 2.3                

| February  | 1.7                

| March     | 3.2                

| April     | 2.9                

| May       | 2.5                

To find the mean monthly rainfall, we add up the rainfall values for each month and divide the sum by the total number of months. In this case, we have five months:

Mean Monthly Rainfall = (2.3 + 1.7 + 3.2 + 2.9 + 2.5) / 5

Calculating the sum of the rainfall values:

Mean Monthly Rainfall = 12.6 / 5

Dividing the sum by the number of months:

Mean Monthly Rainfall = 2.52

Rounded the result to the nearest thousandth, the mean monthly rainfall is approximately 2.520 inches.

Therefore, the mean monthly rainfall, rounded to the nearest thousandth, is 2.520 inches.

Answer: The investment that was put in the account is 6268 at 14%, while the amount that is invested in the stock is 5568 at 11%.

Step-by-step explanation:

Let the amount that is put into the account is x, while the amount that is invested in the stock market is y. Given the investor puts $700 more in the first account than in the stock fund, therefore, the equation can be written as,

x-y=700

x=700+y

Also,  at the end of the year the total interest from the two investments was $1490. Therefore, we can write,

.14x+.11y=1490

Substitute the value of x from the above,

.14(700+y)+.11y=1490

y=5568

substitute the value of y in the first equation,

x-5568=700

x=6268

The investment that was put in the account is 6268 at 14%, while the amount that is invested in the stock is 5568 at 11%.
