Arandom variable is used to find the number of items in a scavenger hunt being held by a local youth group. identify the variable as discrete or continuous and explain.

a.
it is discrete because the number of items in the scavenger hunt is identified using whole numbers.

b.
it is continuous because there is no set limit on how many items are in the scavenger hunt.

c.
it is continuous because the number of items can be measured by any positive rational number.

d.
it is discrete because the number of items in the scavenger hunt is limited to specific amount.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
