The number of songs that Deante' would have downloaded during month 9 is 58 songs.
<h3>What is a regression line?</h3>
A regression line is a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.
By using Microsoft excel to plot the data on a scatter plot, we can logically deduce that line of best fit for the songs downloaded is given by:
y = 2.03x + 39.7
Thus, the number of songs that Deante' would have downloaded during month 9 is:
y = 2.03(9) + 39.7
y = 18.27 + 39.7
y = 57.97 ≈ 58 songs.

Answer:
a = 30
Step-by-step explanation:
a/ 50 = 3/5
Using cross products
a*5 = 50 *3
5a = 150
Divide each side by 5
5a/5 = 150/5
a = 30
The square root of 100 is exactly 10!
10*10=100
10 squared = 100
Square root of 100=10
