A college library has five copies of a certain text on reserve. Three copies (1, 2, and 3) are first printings, and the remainin

g two (4, and 5) are second printings. A student examines these books in random order, stopping only when a second printing has been selected. One possible outcome is 4, and another is 214. (a) List the outcomes in S. (b) Let A denote the event that exactly one book must be examined. What outcomes are in A

Answer:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

A ={(4), (5)}

Step-by-step explanation:

Given that:

Among the three copies, (1,2,3) are the first printings, and (4,5) are the second printings.

A student who examines these books in random order stops when a second printing has been selected.

Thus, we can compute the sample space associated with these experiments as:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

Suppose A represents the event that we must examine exactly one book.

Then the outcomes of A are:

A ={(4), (5)}

Write the product as a trinomial.(k – 1)(k – 4)
SashulF [63]
(k - 1)(k - 4)

Use FOIL to solve this.

First
k * k
Outer
k * -4
Inner
-1 * k
Last
-1 * -4

k^2 - 4k - 1k + 4

k^2 - 5k + 4 is the trinomial.

#1 2x-16<-18
Evgesh-ka [11]

Answer:

if it's finding x

#1 x<-1

#2 x<4

Step-by-step explanation:

#1

2x-16<-18

add 16 to both sides

2x<-2

then divide 2 to both sides

x<-1

#2

2x-16+4x<8

add like terms

6x-16+<8

add sixteen to both sides

6x<24

divide six to both sides

x<4

Yuliya22 [10]

Answer:

The replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2.

Step-by-step explanation:

You would have to multiply:

24 x 1/8 = 3

24 x 1/10 = 2.4

24 x 1/12 = 2

3) WILL MARK BRAINLIEST + 10 POINTS!!!!!! :)

This is really a long way to go to make something complicated
out of something simple.  The last choice does the job.

cos(180)  =  -1
sin(180)  =   0

So       4 [cos(180) + i sin(180) ]

       =   4 [ -1      +  i (0) ]

       =     -4     yay!
