Are they statistical questions?
A question is said to be statistical if it can be answered through data collection and if there are variances in the collected data.
Using this yardstick, we can say that (1) is a statistical question because the frequency at which the band perform in a week can be determined by gathering data of their past practice.
This can not be said of (2) because (2) has not been done yet, there is no available data to make predictions and lastly, the variance of an unavailable data can not be determined.

Step-by-step explanation:
4.2×3=12.6
I hope this answer can help you
A. You are told that the length equals (x + 15), which means that you must factorise the area in order to find the width:
45 ÷ 15 = 3
(x + 15)(x + 3)
So the width is x + 3
b. Now you substitute in the value of x into both brackets, so
length: (x + 15) = (8 + 15) = 23 yards
width: (x + 3) = (8 + 3) = 11 yards
I hope this helps!
