How does translating a figure using the formal definition of a translation compare to the previous method of translating a figure?
This method is easy to understand and easy to apply to any figure than the other methods.
What is a translation of the figure?When the figure is moved from one place to another place is called translation of the figure.
When we add in x then the figure will translate toward the left.
And when we subtract in x then the figure will translate toward the right.
If we add in y then the figure will translate downward.
And when we subtract in y then the figure will translate upward.
This method is easy to understand and easy to apply to any figure than the other methods.
More about the translation of the figure link is given below.

full. How much gas is still in the tank? Give your answer as a whole number or as a mixed fraction reduced to lowest terms
To calculate the amount of gas left in the tank, you should multiply the total capacity of the tank, which is 18 gallons, by the fraction that represents the amount of gas remaining, which is 1/3. Thus, there are 6 gallons of gas still in the tank.
Explanation:
To answer this question, we should multiply the total capacity of the tank, which is 18 gallons, by the fraction that represents the amount of gas remaining, which is 1/3. This will give us the number of gallons of gas left.
Now, apply the multiplication: 18 gallons * 1/3 = 6 gallons.
So, there are 6 gallons of gas still in the tank.

Ernie's favorite movie of the year is now in its fourth week in the theaters. He is gathering data about its earnings each week. He is also interested in knowing how other recently released movies are doing at the box office compared with his favorite movie. The table gives the earnings of the top-five movies during the third week that Ernie’s favorite movie, movie A, was showing in theaters. Movie Earnings Average Ticket Price A $26,088,808.74 $8.35 B $60,394,938.12 $9.72 C $23,659,617.52 $8.12 D $34,311,887.98 $7.57 E $10,505,611.08 $8.46
To compare the relative success of his favorite movie to others, the student can calculate each movie's ticket sales by dividing its total earnings by the average ticket price. This provides a clearer idea of the viewership each movie had, which can be more informative than simple box office earnings.
Explanation:The student is interested in the earnings of his favorite movie in relation to other recently released films. To compare these films, one could calculate each movie's ticket sales by dividing its earnings by the average ticket price. For instance, the ticket sales for the movie A would be calculated by dividing its earnings, $26,088,808.74, by its average ticket price, $8.35. This calculation would need to be repeated for each movie to have a clear comparison.
These calculations will help Ernie understand how many people, roughly, saw each movie, since box office earnings alone can be skewed by differing ticket prices. In other words, a movie could have higher earnings than another but still have fewer viewers if its tickets were significantly more expensive.

To transform the scores to have a mean of 75 and a standard deviation of 12, Ms. Martin needs to subtract the current mean from each test score, divide the result by the current standard deviation, multiply the result by the new standard deviation, and add the new mean to each transformed score.
Explanation:To transform the scores to have a mean of 75 and a standard deviation of 12, Ms. Martin needs to apply two transformations to each test score:
First, she needs to subtract the current mean of 12 from each test score.Then, she needs to divide the result by the current standard deviation of 3.After applying these transformations to all the scores, she needs to multiply each result by the new standard deviation of 12 and finally add the new mean of 75 to each transformed score.By following these steps, Ms. Martin will successfully transform the scores to have the desired mean and standard deviation.
