For the given pair of events A and​ B, complete parts​ (a) and​ (b) below. ​A: When a page is randomly selected and ripped from

a 26​-page document and​ destroyed, it is page 2. ​B: When a different page is randomly selected and ripped from the​ document, it is page 21. a. Determine whether events A and B are independent or dependent.​ (If two events are technically dependent but can be treated as if they are independent according to the​ 5% guideline, consider them to be​ independent.) b. Find​ P(A and​ B), the probability that events A and B both occur. a. Choose the correct answer below. A. The two events are dependent because the occurrence of one does not affect the probability of the occurrence of the other. B. The two events are independent because the occurrence of one does not affect the probability of the occurrence of the other. C. The two events are independent because the​ 5% guideline indicates that they should be treated as independent. D. The two events are dependent because the occurrence of one affects the probability of the occurrence of the other.

Answer:

a. D. The two events are dependent because the occurrence of one affects the probability of the occurrence of the other.

b.  P(A and​ B) = 1 ÷ 676

Step-by-step explanation:

a. The events are said to be independent event if occurrence of one event does not affect the other event.

The event A and B are dependent to each other, Since occurrence of one event does not affect the other event. Also page is selected from the same book.

Thus, Option D is correct.

b. If the both event are independent then,

P(A and B) = P(A∩B) = P(A) × P(B)

⇒P(A∩B) = \frac{1}{26} \times\frac{1}{26} = \frac{1}{676}= 0.0014

Sort the following functions from asymptotically smallest to asymptotically largest, indicating ties if there are any. You do no
Serhud [2]

Answer:

b. n

d. 2^lgn

c. n^2.1

a. 4^2lgn

Step-by-step explanation:

Logarithm is a function of mathematics which is used to calculate inverse function of exponents. The asymptotically smallest function will be the one that has smallest or no exponents. The exponent function is calculated in reverse when log is applied. The function with highest exponents will be largest asymptotically.

In a teacher's math course, a linear regression line was calculated to predict
Marat540 [252]

The given equation is the best line that approximates the linear

relationship between the midterm score and the score in the final exam.

  • AJ's residual is 0.3, which is not among the given options, therefore, the correct option is. <u>E. None of these</u>.

Reasons:

The given linear regression line equation is; \hat y = 25.5 + 0.82·\mathbf{\hat x}

Where;

\hat y = Final exam score;

\hat x = The midterm score;

AJ score in the first test, \hat x = 90

AJ's actual score in the exam = 99

Required:

The value of AJ's residual

Solution:

By using the regression line equation, we have;

The predicted exam score, \hat y = 25.5 + 0.82 × 90 = 99.3

  • The residual score = Predicted score - Actual score

∴ AJ's residual = 99.3 - 99 = 0.3

AJ's residual = 0.3

Therefore, the correct option is option E;

  • <u>E. None of these</u>
