Ok, so if you’re saying -18=r-3, then first you need to add 3 to each side so you can move the 3 with the -18 so you can isolate r. (Leave it by itself). So now your equation is -18+3=r. Next, combine like terms, so do -18+3, which is -15. Now you have -15=r, so r is equal to -15.
1. 2, 4, 8.
2. 2, 3, 5.
3. 2, 3, 5, 6, 8, 10.
Part A: There are five buttons in all in all in the given item. The item above can be answered through the fundamental principles of counting.
There are 5 items to choose from during the first pick. Because the shape can be returned and picked again, there are also 5 items to choose from in the second pick. Multiplying them,
n = 5 x 5 = 25
Therefore, the sample size for the compound event is equal to 25.
Part B: The same concept can be used in this part of the item; however, instead of 5 there are 6 buttons to choose from.
n = 6 x 6 = 36
Hence, the sample size of this picking process is 36.
Hope this handy formula helps!
