Answer:
McCoy should plant soybeans
Step-by-step explanation:
Thinking process:
Let the two crops be corn and soybeans as indicated.
The profit margin for corn will be $ 30 000. However, the loss will be:
$ 35 000 - $ 30 000 = $ 5 000
For the soybean, the profit margin will be $ 10 000.
The loss will be $ 5 000
The net balance will be given as: $ 5 000 - $ 10 000 = - $ 5 000. (This represents a gain)
Thus, soybean will be more profitable.
Given that:
mean,μ=35.6 min
std deviation,σ=10.3 min
we are required to find the value of x such that 22.96% of the 60 days have a travel time that is at least x.
using z-table, the z-score that will give us 0.2296 is:-1.99
therefore:
z-score is given by:
(x-μ)/σ
hence:
-1.99=(x-35.6)/10.3
-20.497=x-35.6
x=35.6-20.497
x=15.103
39,000/1,300 = 30. 30 x 4 = 120 Hours
10x+6y=152
5x+3y=76
7x+12y=200
-20x-12y=-304
-13x=-104
x=8
40+3y=76
3y=36
y=12
