A bag contains:

Mathematics
1 answer:
Lady bird [3.3K]3 years ago
6 0

Answer:

3/50

Step-by-step explanation:

There are 5 + 4 + 2 + 6 + 3 = 20 marbles in the bag

P(draw a black) = 6/20 = 3/10

If the black marble is replaced, then there are 20 marbles in the bag again.

P(draw a blue) = 4/20 = 1/5

P(draw a black and blue with replacement) = (3/10)(1/5) = 3/50

After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand.
alexira [117]

Answer:

c(t) =-18t +212

Step-by-step explanation:

Given

(t_1,c_1) = (4,140)

(t_2,c_2) = (9,50)

Required

Determine the equation

First, we calculate the slope (m)

m = \frac{c_2 - c_1}{t_2 - t_1}

m = \frac{50 - 140}{9-4}

m = \frac{-90}{5}

m = -18

The equation is then calculated as:

c =m(t - t_1) + c_1

c =-18*(t - 4) + 140

c =-18t +72 + 140

c =-18t +212

Hence, the function is:

c(t) =-18t +212
