Answer: C. [tex]\dfrac{1}{3}[/tex]
Step-by-step explanation:
Given: Box contains 8 green balls and 4 purple balls.
Total balls = 8+4 = 12
event 1 = first picking green ball
event 2 = second picking purple balls.
As first ball was replaced, that means both events are independent.
Probability that you have selected a green ball and then a purple ball = P(purple ball )
Formula for probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]
Probability of selecting a purple ball (second pick)= [tex]\dfrac{4}{12}[/tex]
[tex]=\dfrac{1}{3}[/tex]
The required probability [tex]=\dfrac{1}{3}[/tex], so C is correct option.

F(x) = x + 4: find f(4) and f(x) = 10
Answer:
f(4) = 8
f(6) = 10
Step-by-step explanation:
Step 1: Define
f(x) = x + 4
f(4) is x = 4
f(x) = 10
Step 2: Find f(4)
f(4) = 4 + 4
f(4) = 8
Step 3: Find f(x) = 10
10 = x + 4
x = 6

A stem and leaf plot shows the number of kilometers walked for charity. The plot is titled 'Kilometers Walked for Charity.' The numbers 12, 13, 14, 15, 16, and 17 are in a vertical column to the left of a vertical line. · On the same line as 12 but on the right of the vertical line are the numbers 3, 3, 6, 7, 9, and 9. · On the same line as 13 but on the right of the vertical line are the numbers 1, 1, 4, 5, and 5. · On the same line as 14 but on the right of the vertical line are the numbers 0, 0, 2, 3, 3, 8, 8, and 9. · On the same line as 15 but on the right of the vertical line are the numbers 2, 2, 2, 2, 2, 3, 5, 5, and 7. · On the same line as 16 but on the right of the vertical line are the numbers 4, 5, 5, 9, and 9. · On the same line as 17 but on the right of the vertical line are the numbers 3 and 5. The key to the stem and leaf plot identifies that 12 vertical line 3 means 12.3. a. Describe how to find the range of the data set. b. Find the range.
Answer:
For part A: Range is difference between the highest value and lowest value of the data set.
For part B: Range is 5.2
Step-by-step explanation:
For part A:
Range of a data set is difference between the highest value and lowest value of the data set.
For part B:
From stem and leaf and it's key ,we can write our data set as
12.3,12.3,12.612.7,12.9,12.9,13.1,13.1,13.4,13.5,13.5,14.0,14.0,14.2,14.3,14.3,14.8,14.8,14.9,15.2,15.2,15.2,15.2,15.2,15.3,15.5,15.5,15.7,16.4,16.5,16.5,16.9, 16.9, 17.3,17.5.
Lowest value of data set = 12.3
Highest value of the data set =17.5
So, range = highest value- lowest value= 17.5-12.3 =5.2

Josh's chicken soup recipe calls for 212L of chicken stock. Josh makes 314times the recipe for a family reunion. How much chicken stock does Josh use to make soup for the family reunion? Express your answer as a mixed number in the simplest form.
Answer:
[tex]8\dfrac{1}{8}\ L[/tex]
Step-by-step explanation:
Given that,
Amount needed for chicken stock is [tex]2\dfrac{1}{2}\ L[/tex]
Josh makes [tex]3\dfrac{1}{4}[/tex] times the recipe for a family reunion.
Let A is the amount neededto make soup for the family reunion. It can be calculated as follows :
[tex]A=2\dfrac{1}{2}\times 3\dfrac{1}{4}\\A=\dfrac{5}{2}\times \dfrac{13}{4}\\\\A=\dfrac{65}{8}\ L\\\\\text{or}\\\\A=8\dfrac{1}{8}\ L[/tex]

Cholesterol levels in men 18 to 24 years of age are normally distributed with a mean of 178 and a standard deviation of 41. The cholesterol levels in women 18 to 24 years of age has a mean of 167 with a standard deviation of 38. What is the percentage for a 20 year old man with a cholesterol level less than 190?
Answer: 61.51%
Step-by-step explanation:
To find : percentage for a 20 year old man with a cholesterol level less than 190.
20 lies between 18 and 24.
For this , Cholesterol levels are normally distributed with a mean([tex]\mu[/tex]) of 178 and a standard deviation([tex]\sigma[/tex]) of 41.
let X = cholesterol level in 20 year old man.
Required probability = [tex]P(X< 190)=P(\dfrac{X-\mu}{\sigma}<\dfrac{190-178}{41})[/tex]
[tex]=P(z<0.2926)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\= 0.6151 [\text{By p-value table}][/tex]
hence, the percentage for a 20 year old man with a cholesterol level less than 190 = 61.51%

There are 62 eggs in a pile on the desk. Each egg comes in a package of 6. 6 eggs
are added to the pile. How many eggs are
there in the pile?
Given parameters:
Number of eggs in a pile on the desk = 62 eggs
Eggs per package = 6
Number of added eggs = 6
Unknown:
Number of eggs in the pile = ?
Solution:
To find the number of eggs in the pile, simply add the original amount of eggs to that which was added;
Number of eggs in pile = (62 + 6)eggs = 68 eggs
Number of eggs there in the pile are 68 eggs
