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

1<br> Which sequence of transformations takes AA to its image, AB ?
lianna [129]

A rigid transformation preserves the dimensions of the image

The option that gives the sequence of transformation that takes ΔB to ΔB is  the option B.

<u>(B) Reflection across y-axis and a translation 2 units down </u>

Reason:

Question: The sequence of transformation that takes ΔA to image ΔB

<em>From a similar question, we have, ;</em>

<em>The vertices of triangle ΔA are; (-8, 9), (-9, 4), (-3, 4)</em>

<em>The vertices of triangle ΔB are; (8, 7), (3, 2), (9, 2)</em>

<em>The options are; </em>

<em>(A) Reflection over the x-axis and 2 units translation down</em>

<em>(B) Reflection over the y-axis and 2 units translation down</em>

<em>(C) 90° rotation after a translation of 2 units down</em>

<em>(D) 90° rotation after a translation of 12units right</em>

Solution;

The length of the base of ΔA = -3 - (-9) = 6

The length of the base of ΔB = 9 - 3 = 6

Therefore, the length s of triangle A and triangle B are equal

The orientation of the base of ΔA and ΔB are both horizontal

The location of the the side that traverses four cells are both furthest from the y-axis, or the vertical

Therefore, ΔB is a reflection of ΔA across the y-axis

We also have;

The base of ΔB is 2 units lower than the base ΔA

Therefore, the correct option is option B, reflection across y-axis and a translation 2 units down

Translate the phrase into a variable expression: twice the sum of a number and 5
DIA [1.3K]

Answer:

'Twice the sum of a number and 5' can be translated into variable expression such as:

  • 2(n + 5)

Step-by-step explanation:

Given the phrase

<em>Twice the sum of a number and 5</em>

First, let us breakdown the English Phrase

Let the number be = n

The sum of a number 'n' and 5 = n + 5

now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.

Thus,

'<em>Twice the sum of a number and 5</em>' can be translated into variable expression such as:

  • 2(n + 5)
