The most likely correlation coefficient for the set of data shown would be C. 0.19.

The correlation coefficient is a measure of how similar two datasets are acting.

The range of correlation coefficient is [-1, 1]

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases, other data starts decrease in the opposite direction.

If the correlation coefficient comes out as 1, then the values grow exactly similarly, in the same direction.

If the slope of the scatters plot increases from left to your right upwards, the correlation coefficient of the data would be positive.

The scatter plot that is given shows this pattern, therefore, the most likely correlation coefficient of the data set is: C. 0.19.

To find the probabilities in this scenario, we will use the information provided in the survey results.

To find the probabilities in this scenario, we will use the information provided in the survey results. Let's go through each question one by one:

a. The prisoner does not take classes: We can find this probability by adding the number of prisoners who do not take high school or college classes and dividing it by the total number of prisoners. In this case, the number of prisoners who do not take classes is 107 + 32 = 139. The total number of prisoners is 107 + 450 + 32 + 367 = 956. So, the probability is 139/956.

b. The prisoner is under 30 and is taking either a high school class or a college class: We can find this probability by adding the number of prisoners who are under 30 and taking high school or college classes and dividing it by the total number of prisoners. In this case, the number of prisoners who are under 30 and taking high school or college classes is 107 + 450 = 557. So, the probability is 557/956.

c. The prisoner is over 30 and is taking either a high school class or a college class: We can find this probability by adding the number of prisoners who are over 30 and taking high school or college classes and dividing it by the total number of prisoners. In this case, the number of prisoners who are over 30 and taking high school or college classes is 32 + 367 = 399. So, the probability is 399/956.

Answer:

Problem can not be solved

Step-by-step explanation:

* Lets explain how to solve the problem

- A total of 1000 people attended a benefit concert was held to raise

 money for a children foundation

∴ The number of students and adult is 1000

- Student  ticket cost $2 and an adult ticket cost $3

∴ The cost of the student ticket is $2

∴ The cost of the adult ticket is $3

- The organizer raises a total of $5500

∴ The total money earns fro tickets is $5500

- Assume that the number of students who attended the concert

 is x and the number of adults is y

- There are 1000 students and adults attended the concert

∴ x + y = 1000 ⇒ (1)

- The cost of student ticket is $2

∴ The money earned from students is 2 × x = 2x dollars

- The cost of adult ticket is $3

∴ The money earned from adults is 3 × y = 3y dollars

- The total money earned from students and adults is $5500

∴ 2x + 3y = 5500 ⇒ (2)

* Now lets solve the two equation by elimination method

- Multiply equation (1) by -3 to eliminate y

∴ (-3)x + (-3)y = (-3) × 1000

∴ -3x - 3y = -3000 ⇒ (3)

- Add equations (2) and (3)

∴ -x = 2500

- Multiply both sides by -1

∴ x = -2500

∵ x represents the number of the students and never the number

  of student be negative , then the problem can not be solved

Answer:

The triangle with vertices with (3, 5), (-2, 6), and (1, 3) is a right triangle.

Solution:

Given that the vertices of triangle are (3, 5), (-2, 6) and (1, 3)

Let us consider A(3, 5) B(-2, 6) C(1, 3)

If the sum of square of distance between two vertices is equal to the square of distance between third vertices, then the triangle is a right angled triangle.

By above definition, we get  

[tex]BC^{2} + CA^{2} = AB^{2}[/tex] ----- eqn 1

Where AB is the distance between vertices A and B

BC is the distance between vertices B and C

CA is the distance between vertices C and D

Distance between any two vertices of a triangle is given as  

[tex]Distance =  \sqrt{\left(x_{2} -x_{1}\right )^{2} + \left(y_{2} -y_{1}\right)^{2}  }[/tex] ------- eqn 2

Step 1:

Let us find the distance between the vertices A(3,5) and B(-2,6)  

By using equation 2, we get  

[tex]x_{1} = 3, x_{2} = -2, y_{1} = 5 \text { and } y_{2} = 6[/tex]

Distance between vertices A and B =[tex]\sqrt{(-2-3)^{2}+(6-5)^{2}}[/tex]

= [tex]\sqrt{(-5)^{2} + (1)^{2}}[/tex]

= [tex]\sqrt{(-5)^{2} + (1)^{2}}[/tex]

= [tex]\sqrt{25+1}[/tex]

= [tex]\sqrt{26} units[/tex]

Step 2:

Let us find the distance between the vertices B(-2,6) and C(1,3)

By using equation 2, we get  

[tex]x_{1} = -2, x_{2} = 1, y_{1} = 6 \text { and } y_{2} = 3[/tex]

Distance between vertices B and C = [tex]\sqrt{(1-(-2))^{2}+(3-6)^{2}}[/tex]

= [tex]\sqrt{(1-(-2))^{2} + (3-6)^{2}}[/tex]

= [tex]\sqrt{3^{2}+9}[/tex]

= [tex]\sqrt{9+9}[/tex]

= [tex]\sqrt{18} \text { units }[/tex]

Step 3:

Let us find the distance between the vertices C(1,3) and D(3,5)

By using equation 2, we get  

[tex]x_{1} = 1, x_{2} = 3, y_{1} = 3 \text { and } y_{2} = 5[/tex]

Distance between the vertices C and A

= [tex]\sqrt{(3-1)^{2} + (5-3)^{2}}[/tex]

= [tex]\sqrt{2^{2} + 2^{2}}[/tex]

= [tex]\sqrt{4+4}[/tex]

= [tex]\sqrt{8} units[/tex]

Step 4:

By using equation 1,

[tex]BC^{2} + CA^{2} = AB^{2}[/tex]

[tex](\sqrt{18})^{2} + (\sqrt{8})^{2} = (\sqrt{26})^{2}[/tex]

18 + 8 = 26

26 = 26

Hence the condition is satisfied. So the given triangle with vertices with (3,5), (-2,6), and (1,3) is a right triangle.  

The solution for [tex]\(y\)[/tex] in the equation [tex]\(34x + 14y = 5\)[/tex] is [tex]\(y = -\frac{17x}{7} + \frac{5}{14}\).[/tex]

To solve the equation [tex]\(34x + 14y = 5\)[/tex] for [tex]\(y\)[/tex], we need to isolate [tex]\(y\)[/tex] on one side of the equation. Here's the step-by-step process:

1. **Subtract 34x from both sides:**

[tex]\[ 14y = -34x + 5 \][/tex]

2. **Divide both sides by 14 to solve for y:**

[tex]\[ y = \frac{-34x + 5}{14} \][/tex]

Now, let's simplify the expression by breaking it into two terms:

[tex]\[ y = \frac{-34x}{14} + \frac{5}{14} \][/tex]

Simplify each term:

[tex]\[ y = -\frac{17x}{7} + \frac{5}{14} \][/tex]

So, the solution for [tex]\(y\)[/tex] in terms of [tex]\(x\)[/tex] is:

[tex]\[ y = -\frac{17x}{7} + \frac{5}{14} \][/tex]

This equation represents a line in the xy-plane. The coefficient [tex]\(-\frac{17}{7}\)[/tex] is the slope, indicating the rate of change of [tex]\(y\)[/tex] with respect to [tex]\(x\),[/tex] and [tex]\(\frac{5}{14}\)[/tex]is the y-intercept, representing the point where the line crosses the y-axis.

Answer:

Step-by-step explanation:

Find the LCD because like last time, you cannot add or subtract fractions with different denominators.

LCD = 10

Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.

[tex]\frac{2 * 2}{5 * 2}[/tex]

[tex]\frac{4}{10}[/tex]

[tex]\frac{4 + 5}{10}[/tex]

[tex]= \frac{9}{10}[/tex]

Answer:

2/5 + 5/10 = 9/10

Step-by-step explanation:

Turn 2/5 into 4/10 to make the two fractions' denominators the same by multiplying 2 × 2 =4 and 5 × 2 = 10. Then add 4/10 + 5/10 to get 9/10.

Answer:

1000 = 160 + 50x

1000 - 160 = 840

840 = 50x

840/50 = 16.8

he can bring up 16.8 approx., but total boxes would be 16.

Step-by-step explanation:

The equation representing the situation is 150 + 50x <= 1000, where x represents the number of boxes of books the delivery person brings up to the office.

To write an equation, we need to represent the information given in the situation. Let's assign a variable, x, to represent the number of boxes of books the delivery person brings up to the office. The weight of the delivery person is fixed at 150 lbs and the weight of each box is 50 lbs. So, the total weight carried by the elevator is 150 + 50x. The equation representing this situation is 150 + 50x ≤ 1000, since the maximum capacity of the elevator is 1000 lbs.

Answer:

5/8

Step-by-step explanation:

4- 9/4 × 3/2 = 4 - (9 *3) / (4*2)

                    = 4 - 27/8

                    = 4*8/8  - 27/8

                   =  32/8 - 27/8

                    = ( 32-27) / 8

                   = 5/8

The correct value of the expression is 0.625.

To evaluate the expression 4 - 9/4 × 3/2, follow these steps:

Start with the multiplication and division from left to right:

Calculate 9 / 4, which equals 2.25.

Then multiply 2.25 by 3/2, which is 1.5. So, 2.25 × 1.5 = 3.375.

Subtract the result from 4: 4 - 3.375 = 0.625.

So, the evaluated value of the expression 4 - 9/4 × 3/2 is 0.625.

Answer:

Step-by-step explanation:

First  let's look at this with just the whole numbers.  Say someone used 2 kg and had 3 left.  it should be pretty simple to see that you started with 5 kg.  It's basically an algebra problem.  if we say x is the starting amount then x-2 = 3.  You could then solve for x=5.  Now, let's dot he same for your actual numbers.  

x - 3/5 = 2 1/4

x = 2 1/4 + 3/5

Now, to add fractions you need to get the same denominators.  we are just really concerned with 1/4 + 3/5.  Now, you need to knwo you can change fractions.  so 1/4 = 2/8 = 3/12 = 4/16 and so on,  You are basically multiplying the numerator and denominator by the same number.  (1*2)/(4*2) = 2/8.  Now, to make both denominators equal you can multiply one fraction by the other denominator.

1/4 + 3/5

(1*5)/(4*5) + (3*4)/(5*4)

5/20 + 12/20 = 17/20.

So now, back tot he main problem, we are adding 2 1/4 + 3/5 = 2 17/20.  so the starting amount was 2 17/20 kg.

There is another way to add fractions but it is more involved and this always works so this is what I always use.  

Ms. How bought a bag of rice that weighs 57/20 or 2 7/20 kg.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Ms. How bought a bag of rice for dinner.

Assuming she bought x kg of rice.

She used 3/5 kg of the rice and still had 2 1/4 kg left.

∴ x - 3/5 = 9/4.

x = 3/5 + 9/4.

x = (12 + 45)/20 kg.

Answer:

[tex](14+12)\times (8+12) > (14\times 12)+(8\times 12)[/tex]

Step-by-step explanation:

First let us evaluate the value of both the expressions.

[tex](14+12)\times (8+12) = 26\times 20 = 520[/tex]

[tex](14\times 12)+(8\times 12) = 168 + 96 = 264[/tex]

a) Hence, Larry's claim that both the expressions are equivalent is wrong.

The evaluation of the expressions have been shown above. The second expression was obtained by swapping the addition and multiplication order and that created the difference.

b) Clearly,

520 > 264

Therefore,

[tex](14+12)\times (8+12) > (14\times 12)+(8\times 12)[/tex]

[tex](14+12)\times (8+12)[/tex] is greater by the expression  [tex](14\times 12)+(8\times 12)[/tex] by a value of 520 - 264 = 256.

Final answer:

Larry is incorrect; the expressions (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are not equivalent. The first expression equals 520, and the second equals 264, with the first being greater by 256.

Explanation:

No, Larry is not correct. The expressions (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are not equivalent because they do not follow the same mathematical rules. The former is calculated using the distributive property of multiplication over addition, while the latter is simply a sum of two products.

To illustrate, let's compute both expressions:

Comparing the results, 520 is evident greater than 264. The difference between them is 256.

The rules of mathematics are universally valid, and incorrect application of these rules can lead to different outcomes, as shown in Larry's claim.
