In conditional probability, the notation P(
AB) is read:
"The probability of event A occurring given that event B has
occurred."
For example: In the following two-way table
P(Walk to school | Sophomore) = 37(2 + 25 + 3) = 0.1
Grade
Drive to school
Take the bus
Walk
Sophomore
2
25
3
Junior

Senior

P(Take the bus | Sophomore ) = [?]
Round to the nearest hundredth.

Answers

Answer 1

The value of the probability represented by P(Take the bus | Sophomore) is 0.83

What are conditional probabilities?

Conditional probabilities are probabilities that only occurred because an event has already occurred i.e. they are dependent on the initial event

How to determine the conditional probabilities?

From the table of values in the question, we have the following parameters:

Number of students that (Take the bus and Sophomore) = 25Number of students that are (Sophomore) = 2 + 25 + 3

The required probability represented by P(Take the bus | Sophomore ) = [?] is then calculated as:

P(Take the bus | Sophomore) = Number of students that (Take the bus and Sophomore) divided by Number of students that are (Sophomore)

Substitute the known values in the above equation

P(Take the bus | Sophomore) = 25/(2 + 25 + 3)

Evaluate the sum in the denominator

P(Take the bus | Sophomore) = 25/30

Evaluate the above quotient

P(Take the bus | Sophomore) = 0.83

Hence, the value of the probability represented by P(Take the bus | Sophomore) is 0.83

Which expression is equivalent to 54n

Answers

Answer:

Choice A, 20(3n-m)

Step-by-step explanation:

First, lets combine like terms for the question 54n - 20m + 6n,

60n - 20m.

Next, lets rule out the choices that are visibly wrong. This includes Choice B, because it wouldn't equal what is above and Choice C, as it ignores unlike terms.

Now, it is down to Choices A and D. Let's use the distributive property to simplify these options.

Choice A:

20(3n-m)

60n-20m

Choice D:

20(m-3n)

20m-60m

With this, it can be concluded that the correct answer is Choice A since it equals 60n-20m, which is equal to the original question when like terms are combined.

Recall the experiment comparing patients 4 weeks after surgery for carpal

a mean pinch strength of 9.1 kg compared to 7.6 kg for the open- incision

patients.

4. What hypotheses would you test?

5. The P-value of the test was less than 0.05. State a brief conclusion.

Answers

Answer:

4. H0: u1= u2 Ha; u1≠ u2

5. The smaller value of p supports the null hypothesis.

Step-by-step explanation:

4. The null and alternate hypotheses are

H0: u1= u2 i.e there no difference between the mean pinch strengthof the two surgeries

against the claim

Ha; u1≠ u2 i.e there a difference between the mean pinch strengthof the two surgeries

It can be written like this as well

H0: u1 -u2= 0 i.e there no difference between the mean pinch strengthof the two surgeries

against the claim

Ha; u1 -u2≠ 0 i.e there a difference between the mean pinch strengthof the two surgeries

Part 5. The test having a p- value less than 0.05 tells that the null hypothesis cannot be rejected. Theres no evidence to reject the null hypothesis.

The smaller value of p supports the null hypothesis.

[tex]x=0.6[/tex]

Generally the equation for the directly proportional variable is mathematically given by

[tex]y \alpha x[/tex]

[tex]y=kx[/tex]

In circle D with m \angle CDE= 122m∠CDE=122 and CD=6CD=6 units, find the length of arc CE. Round to the nearest hundredth.

Answers

Answer:

12.78 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the question:

θ = 122°

r = 6 units

Therefore, the arc length =

2 × π × 6 × (122/360)

= 12.775810125 units

Approximately to the nearest hundredth = 12.78 units

Therefore, the length of arc CE is 12.78 units
