A secret code is designed by choosing a letter from the alphabet and then choosing a digit from 0-9. which equation below correctly represents the probability of choosing the secret code “7Q” according to the picture?

Answers

This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture. Thus, option (D) is correct.

Event - 1: Choosing a letter from the alphabet that is Q.

Let us assume the probability of happening of event 1 is P(Q).

Event - 2: Choosing a digit from 0-9 that is 7.

Let us assume the probability of happening of event 1 is P(7).

Now, we need to choosing the secret code that is 7Q.

We need to multiply both events to get the desired result.

Thus,

P(7 \cap Q)=P(7) * P(Q)

This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture.

Answer:

Option 4: P(7∩Q) = P(7) × P(Q)

Step-by-step explanation:

P(7∩Q) represents the probability of choosing the secret code "7Q".

If A and B are independent events, then,

P(A∩B) = P(A) × P(B)

Let A be the event of choosing a number from 0-9 and

B be the event of choosing an alphabet.

Clearly, A and B are independent.

Therefore,

P(7∩Q) = P(7) × P(Q)

Find an equation in standard form for the hyperbola with vertices at (0, ±4) and asymptotes at y = ±1 divided by 3.x.

Answers

The transverse axis is parallel to the y-axis (the positive part of this equation.
(h, k) is the center ... (0, 0)
a = distance from the center to the vertices along the transverse axis
b = distance from the center to the endpoints of the conjugate axis
c = distance from the center to the foci along the transverse axis
Given: a = 10
The relationship between a, b, and c is
10² + b² = c²

The slope of the asymptotes is ±5/4
a = is a multiple of 5
b = is a multiple of 4 ... be careful not to always assume that a=5 and b = 4.
For this problem a = 10
hence, b = 8

10² + 8² = c²
164 = c²
2√41 = c

Summary
center = (0, 0)
a² = 100
b² = 64
c² = 164
transverse axis x = 0
equation of the hyperbola

[y²/10²] - [x²/8²] = 1


Remember, the slope of the asymptotes tell you the ratio of a and b, and not necessarily the actual values of a and b.

I hope this helps!

Determine the time needed to deliver 72 papers at rate of 9 papers in 18 minutes.

Answers

Answer:  The required time needed to deliver 72 papers is 2 hours 24 minutes.

Step-by-step explanation:  Given that 9 papers are delivered in 18 minutes.

We are to determine the time needed to deliver 72 papers.

We will be using the UNITARY method to solve the problem.

We have

Time needed to deliver 9 papers = 18 minutes.

So, time needed to deliver 1 minute will be

(18)/(9)=2~\textup{minutes}.

Therefore, time needed to deliver 72 papers is given by

2*72=144~\textup{minutes}=(120)/(60)~\textup{hours},24~\textup{minutes}=2~\textup{hours}~24~\textup{minutes}.

Thus, the required time needed to deliver 72 papers is 2 hours 24 minutes.
So you need to find out time. What you do is divide 72 by 9 to get 8. Once you get 8, you have to multiply it by 18. Your answer is then 144 Papers
