The probability of pulling a classic rock CD is 0.71 and then without replacement probability of pulling Country side CD is 4.
What is Probability?Probability is the chance that something will happen, or how likely it is that an event will occur.
Formula for the calculation of probabilityProbability of an event to happen = [tex]\frac{number of favorable outcomes }{total number of outcomes}[/tex]
According to the given question
we have
a bag which contains ,
country music CDs = 4
pop music CDs = 8
classic rock CDs = 5
total number of CDs = 4+8+5 =17
probability of pulling a classic rock CD = [tex]\frac{5}{17}[/tex] =0.71
without replacing
total number of CDs left = 17-1 =16
probability of pulling a country music CD =[tex]\frac{4}{16}[/tex]=4
Hence, the probability of pulling a "classic rock CD" is 0.71 and then without replacing probability of pulling "country music CD" is 4

f(x) = 3x + 2 and g(x) = x + 5
g[f(x)] =
A. 3x + 7
B. 3x + 17
C. 4x + 7
Answer:
A
Step-by-step explanation:
g[f(x)]=g(3x+2)=3x+2+5=3x+7
The function defined by g[f(x)] is equal to 3x+7. hence the correct option is A.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given the function as
f(x) = 3x + 2 and g(x) = x + 5
We need to find the function defined by g[f(x)]
g[f(x)] = g(3x+2)
g[f(x)] =3x+2+5
g[f(x)] = 3x+7
Therefore, the function defined by g[f(x)] is equal to 3x+7. hence the correct option is A.

Which of the following statements is true about the function presented in the table?
a. The slope of the function is 4 and the y-intercept is 2.
b. The slope of the function is 4 and the y-intercept is -2.
c. The slope of the function is -2 and the y-intercept is 4.
d. The slope of the function is 2 and the y-intercept is 4.
Answer:
C. The slope of the function is -2 and the y-intercept is 4.
Explanation:
The y-intercept is the point when x = 0. On the table when x is 0, y is 4.
The slope of the function is -2 because the y value is going down by 2 for each +1 of x.
x │ y
-2 │ 8
0 │ 4
↓ +1 ↓ -2
1 │ 2
↓ +1 ↓ -2
2 │ 0

How would you graph y = -3x + 4? (With visual, please; will give brainliest!)
Answer:
Step-by-step explanation:
1. Start with the y-intercept, (0,4), plot it on the y-axis.
2. Then using the slope you can find more points on the graph.
- Start with simple x coordinates such as 1,2,3...
- plug each into the equation to find the y cooridnate that makes the x coordinate true.
- write each as a coordinate pair and then plot each pair on the graph.
( you may want to use some negative values for x in order to have ease graphing)
- once you have as many points as you desire, must have atleast 2, draw a line connecting each point.

Do the following points belong to the graph of the function f(x)=13−5x ? (-2,23)
Answer:
Yes!
Step-by-step explanation:
When we have problems like this we just plug them in. We take the -2 and we multiply it by the -5 to get a positive 10. We then add that to the +13 and it equals 23, so it works!
find the median if this set of numbers: 7, 6, 19, 12, 16, 19, 19, 6
Answer:
20
Step-by-step explanation:
Order the numbers from smallest to largest, then cross one number off until you have one or two numbers left.
If there is an EVEN number of numbers(like this one): there will be two numbers left, therefore you add those two numbers together, then divide by two.
If there is an ODD number of numbers: there will be one number left, therefore that is your answer!

Which equation is a linear function?
Answer:
y = xStep-by-step explanation:
In general ,A linear function has the form y = ax + b
so ,the functions :
y = √x
y = x²
y = x³
don’t meet the requirements of the definition
therefore none of them is linear.
but y = x is a valid choice (just put a = 1 and b = 0 in the expression y = ax + b)
Put the following numbers in order from smallest to largest, with the smallest value at the top of the list.

Answer:
The right order is:
0.0851/32/560%3/478%1.05Step-by-step explanation:
To identify the right order of the numbers given in order from the smallest to largest, you first must convert all the numbers to the same mode (fractions, decimals or percentages), in this case, I will transform all the numbers to decimals, for this you must divide the fractions or operate the percentages, and you will obtain:
0.085 = 0.085 1/3 = 0.33333333333 60% = 0.6 2/5 = 0.4 3/4 = 0.75 1.05 = 1.05 78% = 0.78How you can see, in this form is easier than the original form, now you can identify that 2/5 (0.4) is smaller than 60% (0.6) and 1.05 is bigger than 78% (0.78).

0.085

Determine the coordinates of the point on the unit circle corresponding to the given central angle. If necessary round your results to the nearest hundredth 180
Answer:
Option A. (-1, 0)
Step-by-step explanation:
In the figure attached,
Circle O is a unit circle (having radius r = 1 unit)
If a point A with central angles = θ, is lying on the circle then the coordinates of the point A will be,
x = r.cosθ
x = 1.cosθ = cosθ
and y = r.sinθ
y = 1.sinθ = sinθ
Therefore, coordinates representing the point A will be (cosθ, sinθ).
As per question the given point A is lying at P (a point having central angle θ = 180°)
Coordinates of point P will be
(x', y') → (cos180°, sin180°)
→ (-1, 0)
Therefore, Option A will be the answer.

About 150,000 people live in a 8-mile radius of a city's town hall. Find the population density in people per square mile. Round your answer to the nearest whole number.
Answer:
747 people per square mile
Step-by-step explanation:
population of city's town hall = 150,000
Radius of city's town hall = 8 mile
area of any circular shape is given by [tex]\pi r^2[/tex].
r is the radius of circle.
p
Area of city's town hall = [tex]\pi r^2= 3.12*8^2 = 3.14*64 = 200.96[/tex]
Population density for any place is ratio of population of that place to area of that place
Thus
Population density for city's town hall = population of city's town hall /Area of city's town hall
Population density for city's town hall = 150,000/200.96
Population density for city's town hall= 746.42 people per square mile.
Population density for city's town hall Rounded to the nearest whole number is 747 people per square mile.
