28 + 29 + 42 = 28 + 42 + 29 = 99
Commutative property: a + b = b + a
Standard deviation=4.
let the mean be 12 and the score be 0 (therefore 12 point difference.)
0-12/s=-3 (s being standard deviation)
-12/4 = -3
1.) A librarian had to pick thirteen books into boxes.if each box can hold six books ,how many boxes did she need?
2.)Each house a carpenter builds needs six sinks.if he bought twenty-nine sinks,how many houses would that cover?
3.)A flash drive could hold six gigs of data.if you needed to store thirty-nine gigs,how many would you need?
Just to make it clear here is the graph. I was gone so long, it destroyed my answer.
Very briefly
8/30 * 360 = 96 which is the angle for the cloudy days.
12/30 * 360 = 144 which is the angle for the sunny days
10/30 * 360 = 120 which is the angle for the rainy days.
The graph shows how this would be plotted. It's not really well done, but it is there.

Step-by-step explanation:
you multiply -1/2 times a negative 3 u would get a positive 3/2=4
