Since the events are dependent, the probability of occurrence of event B will impact the probability of occurrence of event A. So we will be using the formula of conditional probability to find P(A ∩ B).

P(A|B)= \frac{P(A*B)}{P(B)} \\  \\ 
P(A*B)=P(A|B)P(B)

Here P(A*B) indicates P(A ∩ B).

Using the values, we get:

P(A ∩ B) = 0.25 x 0.4 = 0.1

Thus, option A gives the correct answer.

The shadow of a tree measures 25 feet from its base. The angle of elevation to the Sun is 31º How tall is the tree? Round your a
grigory [225]

Answer: 15 feet

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.  

Tan α = opposite side / adjacent side

Where α is the angle of elevation to the sun, , the opposite side (x) is the height of the tree, and the adjacent side is the length of the shadow.

Replacing with the values given:  

Tan 31 = x /25

Tan 31 (25) =x

x = 15 feet

Feel free to ask for more if needed or if you did not understand something.

If person a and person b go fishing and both catch fish. If person a gives half their fish to person b and then they have equal
Alik [6]

Answer:

The number of fishes person b initially has is 0

The number of fishes person a initially has is x, where x is any natural number

Step-by-step explanation:

The given parameters are;

let x represent the number of fish person a catches and let y represent the number of fishes that person b catches, we have;

x - x/2 = y + x/2

2·x - x = 2·y + x

2·x = 2·y + 2·x

∴ y = 0

Therefore;

The number of fishes person b initially has = 0

The number of fishes person a initially has = x, where x is any natural number.
