Event B is dependent on event A, and event A occurs before event B. Which formula can be used to find the probability of event A?a. P(A and B)
P(B)

b. P(A and B)
P(B|A)

c. P(A and B)
P(A|B)

d. P(A and B) × P(B|A)
e. P(A and B) × P(B)

Answers

Answer 1
Answer:

Answer:

Option d - P(A)=\text{P(A and B)} * P(B|A)

Step-by-step explanation:

Given : Event B is dependent on event A, and event A occurs before event B.

To find : Which formula can be used to find the probability of event A?

Solution :

Event B is dependent on event A

i.e. The intersection of A and B - A and B

Probability of event B is dependent on event A is P(A and B)

Event A occurs before event B

i.e. B|A

Probability of event A occurs before event B is P(B|A)

Event B is dependent on event A, and event A occurs before event B is

\text{P(A and B)} * P(B|A)

The formula which shows the probability of event A is

P(A)=\text{P(A and B)} * P(B|A)

Therefore, Option d is correct.  
Answer 2
Answer: The right answer for the question that is being asked and shown above is that: "d. P(A and B) × P(B|A)." Event B is dependent on event A, and event A occurs before event B. the formula that can be used to find the probability of event A is P(A and B) × P(B|A)

Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 16.

Answers

Answer:

x²/64 + y²/81 = 1

Step-by-step explanation:

Standard form of an equation for the ellipse is (x^(2) )/(a^(2))+(y^(2) )/(b^(2) )=1

Here b is the length of vertical major axis = 9

and minor axis of length a = 8

Therefore the equation of the ellipse will be

(x^(2) )/(8^(2) )+(y^(2) )/(9^(2) ) =1

(x^(2) )/(64)+(y^(2) )/(81)=1

So the answer is x²/64 + y²/81 = 1
Let us assume then that the center is the origin.  If the major axis is 18, then a = 9 and a^2=81.  If the minor axis is 16, then b = 8 and b^2=64.  Now you can write the equation.  Remember that this ellipse is vertical and so a^2 goes under y^2
