The answer would be D. H<span>ow long are the songs you practice playing on your instrument?
Statistical questions are ones that will show variability. The first three questions will have a straight answer. The last one however will have data that varies, since most likely every song is not the same length.

Answer:
C) 42/7 = n
Step-by-step explanation:
A week is 7 days, so, to figure out how many cups of dog food she gives her dog daily, we would need to do her weekly amount, 42, divided by 7, the amount of days in a week :)
Make it an improper fraction by multiplying the whole number by the denominator then adding the numerator then find the common denominator (remember what you do to the bottom, you do to the top) then subtract normally.
eg. 1 4/5 - 1 7/10
= 9/5 - 17/10
= 18/10 - 17/10
= 1/10 or 0.1
Hope this helps!
Answer:
Step-by-step explanation:
Equation of line k is y = (-4/7)x + 1
point (-5,-10); m = -4/7
Line L is perpendicular to k so the perpendicular slope will be 7/4
Equation of line L is (y - y1) = m(x-x1)
y+10 = (7/4) (x +5)
4y + 40 = 7x + 35
4y = 7x - 5
y = (7/4)x - (5/4)
