Answer:
Step-by-step explanation:
We are looking for what number times .50 makes the equation true.
So, just do backwards equation:
Thus, meaning that what multiplied by 0.50 is equal to 17?
[tex]0.50 * 34[tex]
[tex]==> 17[tex]
Answer:
1.0.008
2. 0.0307
3. 12
Step-by-step explanation:
Probability p=0.2
Given that x + k = 3 and k = 3 hence x=0 where k is sales and x is successful visits
1
Required probability =P(x=0)
Using negative binomial distribution
=
=
2 ) Here , Given that , x + k = 5 and k = 3 hence x=5-3=2
Required probability =P(X=2)
Using negative binomial distribution
=
3 ) Given : k = 3 p = 0.2 q = 1 - p = 1 - 0.2 = 0.8
<u><em>Answer:</em></u>
Jenna did 16 regular haircuts
Jenna did 8 haircuts with coloring
<u><em>Explanation:</em></u>
Assume that the number of regular haircuts is x and the number of haircuts plus coloring is y
<u>We are given that:</u>
<u>1- Jenna did a total of 24 clients, this means that:</u>
x + y = 24
This can be rewritten as:
x = 24 - y ...............> equation I
<u>2- regular haircuts cost $25, haircuts plus coloring cost $42 and she earned a total of $736. This means that:</u>
25x + 42y = 736 ..........> equation II
<u>Substitute with equation I in equation II and solve for y as follows:</u>
25x + 42y = 736
25(24-y) + 42y = 736
600 - 25y + 42y = 736
17y = 136
y = 8
<u>Substitute with y in equation I to get x as follows:</u>
x = 24 - y
x = 24 - 8
x = 16
<u>Based on the above:</u>
Jenna did 16 regular haircuts
Jenna did 8 haircuts with coloring
