Researchers often enter a lot of data into statistical software programs. The probability of making zero to two errors per 1,000 keystrokes is 0.51, and the probability of making three to five errors per 1,000 keystrokes is 0.25. Find the probabilities (per 1,000 keystrokes) associated with each of the following.

at most 2 errors:
at least 3 errors:
at most 5 errors:
more than 5 errors:

Answer:

Final answers are ,

• 9

•-7

• 7

• -85

Step-by-step explanation:

Given that when we input a number then first it will be multiplied by 2 and finally decreased by(-1) .

Input 5 :-

• Firstly Multiplying it by 2 → 2× 5 = 10

• Subtracting 1 from it → 10 - 1 = 9

Output = 9

====================================

Input (-3) :-

• Firstly Multiplying it by 2 → 2× -3 = -6

• Subtracting 1 from it → -6- 1 = (-7)

Output = (-7)

====================================

Input 4 :-

• Firstly Multiplying it by 2 → 2× 4 = 8

• Subtracting 1 from it → 8 - 1 = 7

Output = 7

====================================

Input (-42) :-

• Firstly Multiplying it by 2 → 2× -42 = -84

• Subtracting 1 from it → -84 - 1 = -85

Output = (-85)

Answer:

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

Step-by-step explanation:

Let x = Courtney's walking speed

then

(x + 1) = Brandi's walking speed

:

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time

6.5/x + 1 = 5/x

Cross multiply

6.5x= 5(x+1)

6.5x= 5x + 5

6.5x - 5x = 5

1.5x = 5

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

Note that:

(x + 1) = Brandi's walking speed

3.33mph + 1 = 4.33mph

Therefore,

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

The Courtney's walking speed = 3.33 mph. Brandi's walking speed = 4.33 mph.

We have given that,

[tex]6.5x - 5x = 5[/tex]

Courtney's walking speed = 3.33 mph

Brandi's walking speed = 4.33 mph

Let x = Courtney's walking speed

then (x + 1) = Brandi's walking speed

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time.

[tex]6.5/x + 1 = 5/x[/tex]

Cross multiply

[tex]6.5x= 5(x+1)[/tex]

Simplify parenthesis right side

[tex]6.5x= 5x + 5[/tex]

1.5x = 5

Isolate x.

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

(x + 1) = Brandi's walking speed

3.33 mph + 1 = 4.33 mph

Therefore,Courtney's walking speed = 3.33 mph

Brandi's walking speed = 4.33 mph
