Answer:
30 because you have two choices with the same probability
Step-by-step explanation:
There are a total of 30 rock CDs in the bargain bin if the bargain bin contains classical and rock CDs. There are 60 CDs in the bin and choosing a rock CD and not choosing a rock CD have the same number of favorable outcomes.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Let's suppose there is a total n number of rock CDs in the bargain bin.
So the probability of choosing the rock CD = n/60
And the probability of not choosing the rock CD = 1 - n/60
According to the problems:
[tex]\rm \frac{n}{60} =1-\frac{n}{60}[/tex]
[tex]\rm \frac{n}{60}+\frac{n}{60} =1[/tex]
[tex]\rm \frac{2n}{60} =1[/tex]
2n = 60
n = 30
Thus, there are a total of 30 rock CDs in the bargain bin if the bargain bin contains classical and rock CDs. There are 60 CDs in the bin and choosing a rock CD and not choosing a rock CD have the same number of favorable outcomes.

I bought a bag of apples for 500 and sold it for 450 what is the percentage lost
Answer:
10%
Step-by-step explanation:
loss= Cp - Sp
= 500- 450
= 50
loss % = 50/ 500× 100
= 10%
Use the table to write a linear function that relates Y to X
Answer:
y = 3/4x + 10
Step-by-step explanation:
The equation of a line is y = slope * x + y-intercept
To find the slope, you choose two points and do (y1-y2)/(x1-x2): Point 1 can be (4,13) and point 2 can be (8,16) so, slope = (13-16)/(4-8) = -3/-4 = 3/4
The y-intercept is the value of y when x is 0, so it would be 10.
Put it together and you get y = 3/4x + 10

Translate the sentence into an equation. Five more than the quotient of a number and 6 is equal to 2. Use the variable w for the unknown number.
Answer:
The equation that represents the sentence is W + 6 + 5 = 2.
Step-by-step explanation:
Since it is required to propose an equation that reflects that five more than the quotient of a number and 6 is equal to 2, using the variable W for the unknown number, the following equation must be performed to determine what the unknown number is:
W + 6 + 5 = 2
W = 2 - 5 - 6
W = -9
Therefore, the unknown number is -9.

The diagram represents a reduction of a triangle by using a scale factor of 0.8.
Answer:
4.8 inches
Step-by-step explanation:
See comment for complete question
Represent the larger triangle with 1 and the smaller with 2.
So, we have:
[tex]H_1 =6\ in[/tex] -- height of 1
Required
Determine H2 --- Height of 2
To do this we apply dilation formula.
[tex]Original * Scale\ Factor = New[/tex]
In this case:
[tex]H_1 * Scale\ Factor = H_2[/tex]
Substitute 6 for H1 and 0.8 for Scale Factor
[tex]6* 0.8 = H_2[/tex]
[tex]4.8= H_2[/tex]
Hence, the height of the smaller triangle is 4.8 inches
Hong bought 60 CDs that were each the same price. Including sales tax, he paid a total of $100.80. Of that total, $6.60
was tax. What was the price of each CD before tax?
Answer:
$1.57 per CD
Step-by-step explanation:
Subtract the tax from the total then divide by the number of CDs.
100.80-6.60=94.2
94.2/60=1.57
Which of the following is not a real number?
А. 1
B. -4
C. 16
D. 13
B is not a real number.
Real number are numbers that are rational (1, 2, 3, -7, -10 etc) and irriational (pi, 9.7582, 1/7, etc), and can be virtually any number, aside from imaginary numbers. Square roots consist of the same number squared, for example the square root of 9, is 3 or the square root of 10 is 3.162... Both of which are real numbers.
A.) The square root of 1, is 1. 1 is a real number.
B.) The square root of -4 is imaginary. There is no real number that can be squared to get -4.
C.) The square root of 16 is 4. 4 is a real number.
D.) The square root of 13 is 3.605... 3.605... is a real number.
Thus meaning your answer is B.

Five increased by the quotient of x and six is what?
Answer:
[tex]5+\frac{x}{6}[/tex]
Step-by-step explanation:
When we say the quotient of x and six, that means x divided by 6, or x/6, and since is says 5 is increased by this amount, we must add x/6 to 5 and get 5+x/6.
Answer:
i think 6 is divider

segment MU = 3*sqrt(47) = 20.56696Angle E = 47.26789 degreesAngle U = 42.73211 degreesThe decimal values are approximate.
===================================================
Work Shown:
Let x be the length of segment MU
We'll use the pythagorean theorem to find x. This works because we have a right triangle.
a^2 + b^2 = c^2
19^2 + x^2 = 28^2
x^2 = 28^2 - 19^2
x^2 = 784 - 361
x^2 = 423
x = sqrt(423)
x = sqrt(9*47)
x = 3*sqrt(47)
Segment MU is exactly 3*sqrt(47) units long. That approximates to 20.56696
-----------------------
We'll use the cosine ratio to find angle E
cos(angle) = adjacent/hypotenuse
cos(E) = EM/UE
cos(E) = 19/28
E = arccos(19/28)
E = 47.2678899573979
E = 47.26789
Angle E is roughly 47.26789 degrees
------------------------
Since angles U and E are complementary, we can then say,
U+E = 90
U = 90 - E
U = 90 - 47.26789
U = 42.73211
Angle U is roughly 42.73211 degrees.

The midpoint i need help
Answer:
angle WXU=56 degrees
Step-by-step explanation:
WX || TV so angle WXU is congruent to angle TVU
68-3x=84-7x
simplify by adding 7x to each side
68+4x=84
simply further by subtracting 68 from each side
4x=16
divide both sides by 4
x=4
angle WXU=68-3x
substitute for x
angle WXU=68-3(4)=68-12=56 degrees

If you are making a cake for a work potluck, and the recipe calls for 2 cups of flour to serve 8 people, how many cups of flour will you need in order to make a large enough cake to serve 30 people?
Answer:-
7.5 cups of flour is required for 30 people
Step-by-step explanation:-
2 cups = 8 people
x cups = 30 people
[ Cross multiply ]
=> 2×30 = x × 8
=> (2 × 30)/8 = x
=> 60/8 = x
=> 7.5 cups = x
Thus, for 30 people 7.5 cups of flour is required.

5. Using t = 3.14, what is the circumference of a circle with a diameter of 50 units?
Round your answer to the nearest hundredth.
Answer:
1962.5
Step-by-step explanation:
The equation for the circumference of a circle is Area = pi * r squared. So if the diameter is 50, then the radius is 25. 25*25 = 625. Now we do 625 * 3.14 = 1962.5 So your answer is 1962.5 I hope this helps :)
