How to solve propbability Combinations?

There are 26 alphabets in english. Now, if there are no repetitions, then;

Number of ways of selecting first letter = 26

Number of ways of selecting second letter = 25

Number of ways of selecting third letter = 24

Thus;

Number of ways of selecting three letters from the alphabet if there is no repetition is; P(3 letters) = 26 * 25 * 24 = 15600

Number of ways of selecting 1 out of the 9 numbers is = 9

Thus;

Potential passwords that can be created = 15600 * 9 = 140400

Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.

Answers

Answer:

Explained below.

Step-by-step explanation:

The complete question is:

Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.

1. P(Z < 1.62)

2. P(Z > -1.57)

3. P(-1.41 < Z < 0.63)

Solution:

Use Excel to solve the problems.

(1)

P(Z < 1.62) =NORM.S.DIST(1.62,TRUE)

= 0.9474

(2)

P(Z > -1.57) = P (Z < 1.57)

=NORM.S.DIST(1.57,TRUE)

= 0.9418

(3)

P(-1.41 < Z < 0.63) = P (Z < 0.63) - P (Z < -1.41)

=NORM.S.DIST(0.63,TRUE) - NORM.S.DIST(-1.41,TRUE)

= 0.7357 - 0.0793

= 0.6564

2) 97.5 miles

3)I am unsure on

Step-by-step explanation:

1) d=65t means that it is moving 65 miles per that amount of time (in this case using mph)

2) you take your equation "d=65t" and fill in your time (1.5) 65(1.5)=97.5

−2x−(−5−4x)=−5(2x−7)

Answers

Answer:

x = 2.5

Step-by-step explanation:

- 2x - ( - 5 - 4x ) = - 5 ( 2x - 7 )

- 2x + 5 + 4x = - 10x + 35

- 2x + 4x + 10x = 35 - 5

12x = 30

x = [tex]\frac{5}{2}[/tex] = 2.5

Check the answer:

L.H.S. = - 2(2.5) - [ - 5 - 4(2.5) ] = 10

R.H.S. = - 5 [ 2(2.5) - 7 ] = 10
