Webb$\begingroup$ An ice-cream store manufactures unflavored ice-cream and then adds in one or more of 5 flavor concentrates (vanilla, chocolate, fudge, mint, jamoca) to create the various ice-creams available for sale in the store. So the number of different flavors is $\sum_{k=1}^5 \binom{5}{k}$. Try calculating the number of flavors by hand. For extra … WebbThe trick is to consider the sum — k3]. On the one hand, this new sum collapses to (PH—13) -f- + + 1) 3 — (n + 1)3— 3 On the other hand, using our summation rules together with [sfl] gives us Equating the right hand sides of the above identities gives us: If we solve for S and properly factor the terms, we obtain our desired expression. 121 WebbA summation is simply the act or process of adding. Examples of summations: 1 + 2 + 3 + 4 + 5 = 15 2 + 2 + 2 + 2 = 8 3 + 6 + 9 = 3 ( 1 + 2 + 3) = 3 (6) = 18 1+10 + 100 + 1000 = 10 0 + 10 1 + 10 2 + 10 3 = 1,111 Summation Notation Involves: The summation sign, S, instructs us to sum the elements of a sequence. did iowa basketball win yesterday
