Of all the trees planted last year by a landscaping firm, only 1 in 10 trees died within a month. Suppose a new landscaping firm is hired to plant 15 new trees. Let X denote the number of trees planted (out of 15) that died. What is the highest value of X that is consistent with the belief that the tree died due to natural causes

The highest value of X that is consistent with the belief that the tree died due to natural causes is:

1.5

Step-by-step explanation:

a) Data and Calculations:

Proportion of trees planted last year that died within a month = 1/10 or 10% (1/10 * 100)

Number of new trees planted by a new landscaping firm = 15

Let X = number of trees planted (out of 15) that died

Since it is believed that the earlier trees died out of natural causes,

Therefore, X = 10% of 15

= 1.5

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
