Aforest consists of two types of trees: those that are 0–5 ft and those that are taller than 5 ft. each year, 40% of all 0–5ft tall trees die, 10% are sold for $20 each, 30% stay between 0 and 5 ft, and 20% grow to be more than 5 ft. each year, 50% of all trees taller than 5 ft are sold for $50, 20% are sold for $30, and 30% remain in the forest. a what is the probability that a 0–5-ft tall tree will die before being sold? b if a tree (less than 5 ft) is planted, what is the expected revenue earned from that tree?

a. 40%

b. $3.2

Step-by-step explanation:

a. As each year 40% of all 0-5ft trees die and other 10% are sold. That means the probability of a 0-5ft tall tree will die before being sold is 40%.

b. The probability of a tree that grows from 0-5ft to more than 5 ft AND get sold is

20% * 20% = 0.2 * 0.2 = 0.04

The probability that a tree stays the same and gets sold in the following year is small and can be neglected.

The expected value to earn from a planted tree is the combination of the expected value of its being sold at between 0-5ft and when it's more than 5 ft

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
