View Exa Cecil solved a theoretical prediction problem and got this "The spinner will land on the red

section 5.5 times." Is it possible to have a prediction that is not a whole number? If so, give an example.

Step-by-

(select) but only (select)

because in reality, nothing can occur 0.5 times.

The fractional probability that a flipped coin lands heads up is

So, in theory, in 35 flips, you

can expect heads about

(as a fraction or

(as a decimal) times. A realistic prediction

is

times.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
