Answer:
A.
, because probability values cannot be greater than 1.
C. -1.5, because probability values cannot be less than 0.
Step-by-step explanation:
Probability is the extent to which an event is likely to happen. It ranges from 0(impossible) to 1(certain). Probability values can be written in decimal form or in fractional form.
The following numbers could not be used to represent the probability of an event.
A.
, because probability values cannot be greater than 1.
C. -1.5, because probability values cannot be less than 0.
Please refer the attached figure for better understanding of the solution
Here we are given that the angle of depression is 40°
And the height of the boat from the water is 25.17 ft
we need to find the length of the rope used which we can take as x
We can see that sin is the ratio that corresponds to the opposite side and the hypotenuse sides of the triangle formed
so we have
sin 40° = 



Hence the length of the rope needed is 39.16 ft
Area = length × width
Length = 3/4
Width = 1/4
Multiply:
3/4 × 1/4 = 3/16
Area = 3/16 square yards
Hope this helped☺☺
