Answer:
P(spin a multiple of 3 = 1/3
Step-by-step explanation:
multiple of 3 = 3,6,9,12
P(spin a multiple of 3) = 4/12 = 1/3
(-2) + 6 + 1 = 1 + 6 + (-2)
-2 + 7 = 7 - 2
5 = 5
3/10, 30%, 0.3
because 3/10 basically means 3 out of 10. that's 30%. 0.3 is just 3/10 in decimal form.
Answer:
See below in bold.
Step-by-step explanation:
The formula is Tn = n(n + 1) / 2
The first triangular number is 1(1+1) / 2 = 2/2 = 1.
So the 15th = 15(15+1) / 2 = 120.
and the 19th = (19 * 20) / 2 = 190.
