Mark has a bag containing a mixture of 30 green and white
marbles. Without looking, he guesses that half of the marbles in
the bag are green. He randomly selected 1 marble from the bag,
recorded the color, and returned the marble to the bag. After 15
trials, Mark has drawn 10 green marbles and 5 white marbles.

goog be able to you with that maybe

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
