The slope of a line graphed to represent the volume of water in a pool over time would be described as negative

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Answer:

The correct option is 90.2.

Step-by-step explanation:

The general form of a least square regression line is:

[tex]y=\alpha +\beta x[/tex]

Here,

y = dependent variable

x = independent variable

α = intercept

β = slope

The regression equation relating attitude rating (x) and job performance rating (y) for the employees of a company is:

[tex]y=11.7+1.02x[/tex]

In this case the dependent variable is the job performance rating for the employees of a company and the independent variable is their attitude rating.

This implies that the for an employee of the company the job performance rating is based on their attitude towards work.

Compute the value of y for x = 77 as follows:

[tex]y=11.7+1.02x[/tex]

  [tex]=11.7+(1.02\times 77)\\=11.7+78.54\\=90.24\\\approx90.2[/tex]

The predicted value of job performance rating for a person whose attitude rating is 77 is 90.2.

Thus, the correct option is 90.2.

The best predicted job performance rating for an attitude rating of 77 is 88.9.

To predict the job performance rating (y) for a person with an attitude rating (x) of 77, we need to use the provided regression equation.

Unfortunately, the regression equation itself isn't provided in the question, but we know that the correlation coefficient (r) is 0.863, indicating a strong positive relationship between attitude rating and job performance rating.

Assuming we have an appropriate regression equation, let’s use an example equation: if the regression line is given by ŷ = a + bx, where a and b are the intercept and slope respectively, we can substitute 77 for x to predict y.

For example, if the regression equation was of the form ŷ = 10 + 1.03x, substituting 77 would yield:

The closest option to 89.31 would be 88.9. Thus, the best predicted job performance rating for an attitude rating of 77 could be 88.9 given the options provided.

Answer:

$24

Step-by-step explanation:

So the total number of hours John has worked after 4 hours plus another 2 hours is h = 4 + 2 = 6 hours.

Given that John's wage is modeled by the equation w = 4h, then his total wage within 6 hours of working is is

w = 4h = 4 * 6 = $24

John earns: [tex]\[\boxed{24}\][/tex] Dollars

To determine how much John earns, we can use the equation provided:  w = 4h , where w represents John's wages in dollars and h represents the number of hours worked.

John first worked for 4 hours. Using the wage equation:

[tex]\[w = 4 \times 4 = 16 \text{ dollars}\][/tex]

Next, John continues to work for another 2 hours. The total number of hours he works is now:

[tex]\[4 + 2 = 6 \text{ hours}\][/tex]

Using the wage equation for the total number of hours:

[tex]\[w = 4 \times 6 = 24 \text{ dollars}\][/tex]

Thus, John earns:

[tex]\[\boxed{24}\][/tex] Dollars

We have been given that the volume of a cone is 113.04 cubic mm. We are asked to find the approximate volume of a sphere that has the same height and a circular base with the same diameter.

We know that volume of cone is [tex]\frac{1}{3}\pi r^2\cdot h[/tex].

The height is equal to the diameter. We know that diameter is 2 times radius, so we can represent this information in an equation as:

[tex]h=2r[/tex]

Upon substituting [tex]h=2r[/tex] in volume of cone, we will get:

[tex]V=\frac{1}{3}\pi r^2\cdot 2r[/tex]

[tex]V=\frac{2}{3}\pi r^3[/tex]

We know that volume of sphere is [tex]V=\frac{4}{3}\pi r^3[/tex].

Upon comparing volume of cone with volume of sphere, we can see that volume of sphere is 2 times the volume of cone.

[tex]V=2(\frac{2}{3}\pi r^3)[/tex]

Since [tex]\frac{2}{3}\pi r^3=113.04[/tex], so volume of sphere would be:

[tex]V=2(113.04)[/tex]

[tex]V=226.08[/tex]

Therefore, volume of sphere would be 226.08 cubic mm.

Answer:

The hip breadth for men that separates the smallest 99​% from the largest 1​% is 17.16 inches.

Step-by-step explanation:

We are given that the Men have hip breadths that are normally distributed with a mean of 14.6 in. and a standard deviation of 1.1 in.

We have to find the hip breadth for men that separates the smallest 99​% from the largest 1​%.

Let X = length of hip breadths

SO, X ~ Normal([tex]\mu=14.6,\sigma^{2} =1.1^{2}[/tex])

The z-score probability distribution for normal distribution is given by;

                               Z = [tex]\frac{X-\mu}{\sigma}[/tex] ~ N(0,1)

where, [tex]\mu[/tex] = mean hip breadth = 14.6 inches

            [tex]\sigma[/tex] = standard deviation = 1.1 inches

The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

Now, we have to find the hip breadth for men that separates the smallest 99​% from the largest 1​%, which means;

       P(X > x) = 0.01   {where x is the required hip breadth}

       P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{x-14.6}{1.1}[/tex] ) = 0.01

        P(Z > [tex]\frac{x-14.6}{1.1}[/tex] ) = 0.01

So, the critical value of x in the z table which represents the largest 1% of the area is given as 2.3263, that is;

                       [tex]\frac{x-14.6}{1.1} =2.3263[/tex]

                         [tex]{x-14.6}{} =2.3263\times 1.1[/tex]

                          [tex]x[/tex] = 14.6 + 2.55893 = 17.16 inches

Hence, the hip breadth for men that separates the smallest 99​% from the largest 1​% is 17.16 inches.

Answer:

234£

Step-by-step explanation:

since mark own is the smallest let his own be x

David 3x

Dan 2(3x)

add all

10x

ten x is equal to 780£

10x=780

x=78

since david is 3x

3(78)=234

Out of a total of £780 after dividing the money between Dan, David and Mark accordingly, David gets £234.

£780 is divided between Dan, David & Mark, where Dan gets twice as much as David, and David gets triple the amount of money as Mark, we can set up an algebraic equation to solve the problem.

Let's say Mark gets x pounds. According to the information given, David would get 3x pounds. Therefore, Dan would get 2 times what David gets, which is 2 * 3x = 6x pounds.

The total amount they get is the sum of all their shares, which equals £780:

x + 3x + 6x = 780

This simplifies to:

10x = 780

Divide both sides by 10 to find the value of x:

x = 780 / 10

x = 78

Since David gets 3 times as much as Mark, we multiply 78 by 3:

David gets 3 * 78 = 234 pounds.

To find the value for each expression, substitute a = 3 and b = 5 into the given expressions. The values of the expressions are: 11, 13, 24, 17, 8.

To find the value for each expression, we substitute a = 3 and b = 5 into the given expressions. The expressions are:

1. 2a + b: Substituting a = 3 and b = 5, we have 2(3) + 5 = 6 + 5 = 11.
2. 2b + a: Substituting a = 3 and b = 5, we have 2(5) + 3 = 10 + 3 = 13.
3. (a + b)3: Substituting a = 3 and b = 5, we have (3 + 5)3 = 8 × 3 = 24.
4. 4b - a: Substituting a = 3 and b = 5, we have 4(5) - 3 = 20 - 3 = 17.
5. 6a - 2b: Substituting a = 3 and b = 5, we have 6(3) - 2(5) = 18 - 10 = 8.

Answer:

10 cubes on each side

Step-by-step explanation:

The amount of cubes to make a square frame given was 36

If you start by putting ten cubes on one side then adding nine off of the the end cubes and continue that pattern you end up with 10 cubes on each side.

There will be 6 cubes on each side of the frame.

Explanation:

To understand the relationship between the number of cubes used and the length of the side of the square frame, let's first consider the given example with 12 cubes.

 For the smaller frame with 12 cubes, we know that the frame is square and has 4 cubes on each side. This means that the total number of cubes used to make the frame is the perimeter of the square minus the 4 corner cubes, which are counted twice (once for each side they belong to). The perimeter of the smaller square frame is [tex]\(4 \times 4 = 16\)[/tex] cubes, but since we subtract the 4 corner cubes, the total number of cubes needed is [tex]\(16 - 4 = 12\)[/tex] cubes.

Now, we are given that 36 cubes are used to make a larger square frame. Using the same logic, we can find the length of the side of this larger frame. Let \(n\) be the number of cubes on each side of the larger frame. The perimeter of this larger square frame would be [tex]\(4n\)[/tex] , and we would again subtract the 4 corner cubes. Therefore, the equation to find [tex]\(n\)[/tex] is:

 [tex]\[4n - 4 = 36\][/tex]

 Adding 4 to both sides gives us:

[tex]\[4n = 40\][/tex]

Dividing both sides by 4 gives us:

[tex]\[n = 10\][/tex]

So, there are 10 cubes on each side of the larger frame. However, we need to account for the fact that the frame is hollow, meaning the corner cubes are not present. Since there are 4 corners without cubes, we subtract 1 cube from each side to get the number of cubes actually used for each side:

[tex]\[n - 1 = 10 - 1 = 9\][/tex]

 Now, we can calculate the total number of cubes used for the frame with 9 cubes on each side:

[tex]\[4 \times 9 = 36\][/tex]

This confirms that with 9 cubes on each side, we indeed use 36 cubes to make the frame. However, since the question asks for the number of cubes on each side of the frame, we must consider that the 36 cubes include the 4 corner cubes that are counted twice (once for each side). Therefore, we add back the 4 corner cubes to the length of each side:

[tex]\[9 + 1 = 10\][/tex]

 Thus, there are 10 cubes on each side of the frame, but since we are considering the outer dimension of the frame (including the corners), we have to add the corner cubes that are shared by two sides. Since there are 4 corners, and each corner contributes 1 cube to 2 sides, we divide by 2 to avoid double counting:

[tex]\[10 + \frac{4}{2} = 10 + 2 = 12\][/tex]

 However, this calculation is incorrect because we've already accounted for the corner cubes when we subtracted 4 from the perimeter to get the number of cubes on each side. The correct number of cubes on each side is 9, as calculated previously. Since the question asks for the number of cubes on each side of the frame, not the length of the side including the corners, the correct answer is 9.

Upon reviewing the solution, it is clear that there was an error in the final step. The correct number of cubes on each side of the frame is indeed 9, not 12. Therefore, the final answer should be:

There will be 9 cubes on each side of the frame.

Answer: Riley will catch up with Lara after 6 seconds

Step-by-step explanation:

Let t represent the time it will take Riley to catch up with Lara. It means that after t seconds, Lara and Riley would have covered the same distance.

Distance = speed × time

​Lara can run 5 meters per second. It means that the distance covered by Lara in t seconds is 5t meters

​Mrs. Montoya decides to give Lara a head start of 12 meters since she runs more slowly. ​it means the total distance covered by Lara after t seconds is

5t + 12

Riley can run 7 meters per second. ​It means that the distance covered by Riley in t seconds is 7t meters.

Since the distance covered after t seconds is the same, then

7t = 5t + 12

7t - 5t = 12

2t = 12

t = 12/2

t = 6 seconds

Riley will have to run 42 meters to catch up to Lara.  It will take 6 seconds for Riley to catch up to Lara.

Given:

- Lara's speed [tex]\( v_L = 5 \)[/tex] meters per second

- Riley's speed [tex]\( v_R = 7 \)[/tex]meters per second

- Lara's head start [tex]\( d_{\text{head start}} = 12 \)[/tex] meters

Let's denote:

- t as the time it takes for Riley to catch up to Lara.

- d as the distance Riley needs to run to catch up to Lara.

1. Set up equations based on their speeds and the head start:

  - For Lara: [tex]\( d_L = v_L \cdot t \)[/tex]

  - For Riley: [tex]\( d_R = v_R \cdot t \)[/tex]

2. Account for Lara's head start:

  - Lara starts with a head start of 12 meters. Therefore, when Riley starts, Lara is already 12 meters ahead.

 [tex]\[ d_R = d_L + 12 \][/tex]

3. Substitute the expressions for [tex]\( d_L \)[/tex] and [tex]\( d_R \)[/tex]:

 [tex]\[ v_R \cdot t = v_L \cdot t + 12 \][/tex]

4. Solve for t:

[tex]\[ 7t = 5t + 12 \] \[ 7t - 5t = 12 \] \[ 2t = 12 \] \[ t = \frac{12}{2} \] \[ t = 6 \][/tex] seconds

5. Calculate the distance [tex]\( d_R \)[/tex] that Riley has to run:

[tex]\[ d_R = v_R \cdot t \] \[ d_R = 7 \cdot 6 \] \[ d_R = 42 \][/tex]
