x= 99.98 min
Total time taken to fill the pool is 100 minutes
Given:
Amount of water already in pool = 1200 gallon
Total capacity of pool = 2160 cubic feet
Rate of water supply = 20 cubic feet per minute
Find:
Total time taken to fill the pool
Computation:
1 cubic feet = 7.5 gallon water
Amount of water already in pool = 1200 / 7.5
Amount of water already in pool = 160 cubic feet
Remain volume = 2160 - 160
Remain volume = 2000 cubic feet
Total time taken to fill the pool = 2000 / 20
Total time taken to fill the pool = 100 minutes

Suppose that we have the least squares regression line y = 3 + 2x and that the sum of the squares of the errors (sse) for this line is 13,712. what can be said about the sum of the squares of the errors (sse) for this data set and the line y = 3 + 2.5x?
The question involves linear regression and the sum of squared errors (SSE), which quantify the total deviation of the response values from the fitted line. If y=3 + 2x is the best-fit line, then the SSE for the line y=3 + 2.5x would be greater than 13,712.
Explanation:The question involves the concept of linear regression and the sum of squared errors (SSE). The SSE of a regression line is quantified by the difference between the observed and predicted values of the dependent variable, each squared and added together. These show how well the regression line fits the data.
In the context of this question, you're given the SSE for the line y = 3 + 2x. However, you're asked about the SSE for the line y = 3 + 2.5x. Since the slope of this new line is steeper, the predicted y-values will be different from those from the original line and generally farther from the actual data points. Therefore, it can be said that if the line y = 3 + 2x is the best-fit line, then the SSE for the line y = 3 + 2.5x would be greater than 13,712.
Error in prediction is generally greater when we move away from the least-squares regression line. Thus the SSE provides a quantifiable way to determine the line that best fits the data.

Kerianne paints landscapes, and in late 2018 placed four paintings with a retail price of $160 each in the Holmstrom Gallery. Kerianne’s arrangement with Holmstrom is that Holmstrom will earn a 10% commission on paintings sold to gallery patrons. As of December 31, 2018, one painting had been sold by Holmstrom to gallery patrons.
Holmstrom earned a commission of $16 for the painting sold to gallery patrons.
Explanation:The subject of this question is Mathematics and the grade level is High School.
To calculate the commission earned by Holmstrom for the painting sold, we can use the formula: commission = (retail price * commission rate) / 100. In this case, the retail price of the painting is $160 and the commission rate is 10%, so the commission earned by Holmstrom for the painting sold is $16.
Therefore, Holmstrom earned a commission of $16 for the painting sold to gallery patrons.

The revenue Kerianne should recognize in 2024 with respect to these four paintings is $216.
The retail price for each painting is $270. Holmstrom Gallery earns a 20% commission on each painting sold.
The steps are:
Calculate the commission by multiplying the retail price by the commission rate:270 × 0.20 = 54
Determine the net revenue for one painting: Subtract the commission from the retail price:270 − 54 = 216
Calculate total revenue for the paintings sold:Only one painting was sold by December 31, 2024. So, the total revenue Kerianne should recognize for 2024 is the net revenue from one painting:
216 × 1 = 216
The correct question is given below,

Step-by-step explanation:
if the mechanical advantages of the component machines in the peeler are 2, 3, and 12, what is the overall mechanical advantage of the apple peeler?
Final answer:
The overall mechanical advantage of an apple peeler with component mechanical advantages of 2, 3, and 12 is the product of these numbers, which is 72. This implies that the input force applied to the apple peeler is multiplied by 72 times.
Explanation:
The student is asking about the overall mechanical advantage of an apple peeler, which is a complex machine made up of components with individual mechanical advantages. To find the total mechanical advantage of a complex machine, you would multiply the mechanical advantages of each component together.
Given that the mechanical advantages of the component machines are 2, 3, and 12, we can calculate the overall mechanical advantage as follows:
Mechanical Advantage of Component 1: 2
Mechanical Advantage of Component 2: 3
Mechanical Advantage of Component 3: 12
To find the overall mechanical advantage, just multiply these together:
Overall Mechanical Advantage = 2 × 3 × 12 = 72
So, the overall mechanical advantage of the apple peeler is 72. This means the input force is multiplied 72 times.
