From the question, we know that

a ballroom features a square dance floor, which has an area of 400 square feet.

The formula for the area of a square is the side squared. Hence, we can determine the side length. Taking the square root of both sides, upon increasing the side length by one foot, we arrive at a side length of 21 feet, which is not a perfect square. The area of 441 is indeed a perfect square and a rational number. Consequently, the true statements are A and E.

zzz [12365]

The provided number is 0.555, which can also be expressed as

0+ \frac{1}{10}*5 + \frac{1}{100}* 5+ \frac{1}{1000} * 5

In examining the digits post-decimal, each subsequent digit decreases to 1/10 of the preceding one.

Thus, the assertion that "the value of the 5 in the thousands place is ten times as great as the 5 in the hundredth place" is incorrect.

Which statements describe a residual plot for a line of best fit that is a good model for a scatterplot? Check all that apply.
babunello [11817]

Response: The accurate statements include:-

There are nearly equal quantities of points located above and below the x-axis.

The points are distributed haphazardly without a distinct pattern.

The total number of points matches that of the scatter plot.

Explanation:

  • A residual plot illustrates residuals on the vertical axis against the independent variable on the horizontal axis.

Consequently, the count of points is on par with the scatter plot, and roughly the same amount of points exist above and below the x-axis.

Given the random distribution of the points throughout the plot, it signifies there is no correlation, therefore, the points are scattered randomly without a clear arrangement.

Leona [12618]
To illustrate, depict a cake or pie divided into 24 segments. Then, surround this cake with 6 figures, applying a distinct color for each set of 4 cake pieces and matching it to the respective figure.

For example, if 4 segments of cake were colored red, then one of the figures should also be red, ensuring that each figure corresponds to 4 pieces of cake.
