amy, beth, and jo listen to four different songs and discuss which ones they like. no song is liked by all three. furthermore, for each of the three pairs of the girls, there is at least one song liked by those girls but disliked by the third. in how many different ways is this possible?
There are 132 different ways this is possible(given situation).
What is probability ?Probability turned into added into arithmetic to are expecting the possibility of an occasion occurring. Probability essentially approach how in all likelihood it's miles that some thing will happen. This is the fundamental principle of possibility and is likewise utilized in possibility distributions to examine feasible consequences of random experiments.
Calculationlet[tex]$AB, BJ$, and $AJ$[/tex] denote a song that is liked by Amy and Beth (but not Jo), Beth and Jo (but not Amy), and Amy and Jo (but not Beth), respectively. Similarly, let[tex]$A, B, J,$ and $N$[/tex] denote a song that is liked by only Amy, only Beth, only Jo, and none of them, respectively. Since we know that there is at least[tex]$1\: AB, BJ$, and $AJ$[/tex], they must be[tex]$3$[/tex] songs out of the [tex]$4$[/tex] that Amy, Beth, and Jo listened to. The fourth song can be of any type
[tex]$N, A, B, J, AB, BJ$, and $AJ$ (there is no $ABJ$[/tex]
because no song is liked by all three, as stated in the problem.) Therefore, we must find the number of ways to rearrangeand a song [tex]$AB, BJ, AJ$,[/tex]from the se[tex]t $\{N, A, B, J, AB, BJ, AJ\}$.[/tex]
Case 1: Fourth song =[tex]$N, A, B, J$[/tex]
Note that in Case 1, all four of the choices for the fourth song are different from the first three songs.
Number of ways to rearrange =[tex]$(4!)$[/tex] rearrangements for each choice[tex]$*\: 4$ choices = $96$.[/tex]
Case 2: Fourth song =[tex]$AB, BJ, AJ$\\[/tex]
Note that in Case 2 all three of the choices for the fourth song repeat somewhere in the first three songs.
Number of ways to rearrange = [tex]$(4!/2!)$[/tex]rearrangements for each choice [tex]$*\: 3$ choices = $36$.[/tex]

10 times 10+10y=-20 what is the value of the y-coordinate
The value of the y-coordinate as calculated from the equation 10+10y=-20 is -3
The given equation is 10+10y=-20
We will solve this linear equation by taking the y coordinate of the function.
Subtracting 10 from both sides of the equation:
or ,10+10y -10 = -20 -10
or, 10y = -30
Dividing both sides by 10 we get:
or, 10y ÷10 = -30 ÷ 10
or, y = -3

there are 120 people in a theatre 72 are female of these 41 purchase an ice cream 36 males purchase and ice cream use this information to compete the frequency tree
There are 120 people in a theatre. 72 are female and 48 are male. 12 females purchase an ice cream and 31 males purchase an ice cream.
What is Frequency Tree?
Frequency trees display the real frequency of certain events. They can display the same data as a two-way table, but frequency trees are more readable since they illustrate the frequency hierarchy. Probability trees depict the likelihood of a series of occurrences.
Solution:
From the question, we can see the there are 120 people in the theatre.
Since, there are 72 females in the theatre we can find the total number of males by 120-72 = 48
Also, the male who purchased Ice Cream were 36 therefore, the males who did not purchased Ice Cream are 48-36 = 12
And, the females who purchased Ice Cream are 41. So, the female who did not purchased Ice Cream are 72 - 41 = 31

You need to Find m < B
Answer:
mAngleB = 67°
Step-by-step explanation:
The angle marked 15x is made by extending one side of the triangle. That is an exterior angle (like, its outside the triangle)
There are two angles inside the triangle that are away from that exterior angle. They are called remote interior angles. They are marked 83° and 6x+7 in this question.
Here's the rule:
If you add up the two remote interior angles it equals the exterior angle.
83° + 6x + 7 = 15x
Subtract 6x.
83 + 7 = 9x
Simplify.
90 = 9x
Divide by 9.
10 = x
Use this to find mAngleB
mAngle B = 6x + 7
= 6(10) + 7
= 60 + 7
= 67
mAngleB = 67°

What is simple interest?
A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,
The formula for simple interest is:
S = p*t*r/100
where P is the principal amount of money, R is the interest rate as a decimal, T is the time.
We'll figure out how to solve the two-equation linear system:
We'll set x equal to 8% of the investment and y equal to 5% of the investment.
Equation 1: x + y = 2900 (total invested money)
Equation 2: 0.06x + 0.04y = 138 (total interest of both investments)
25*(0.06x+0.04y = 138)
Equation 3: 1.5x + y = 3450

0.5x = 550
x = 550/0.5 = 1100

Brady's father is paying $60 for a monthly gym membership. the gym is offering a special sale for 18% off the regular price. After the discount, a 10% maintence fee is charged. what does brady's father pay for the gym membership? explain.
============================================================
Explanation:
If his father saves 18%, then he pays the remaining 82% since 100-18 = 82.
The 82% then converts to 0.82 which is one of the multipliers we'll use to get the answer.
The other multiplier is 1.10 to represent an increase of 10%
The net multiplier is 0.82*1.10 = 0.902
Therefore, his father pays 0.902*60 = 54.12 dollars after the discount and maintenance fee are applied.
Rewrite the equation in terms of x.
y =4/7(x-13)
Answer:
y=(47)xy=(47)x
Rewrite the equation as 47x=y47x=y.47x=y47x=y
Multiply both sides of the equation by 7474.74(47x)=74y74(47x)=74ySimplify both sides of the equation.Tap for more steps...x=7y4
Step-by-step explanation:
confusing bro
Answer:
x = (4/7y) + 13
Step-by-step explanation:
y = 4/7( x -13)
cross multiply
y x 7( x -3) = 4
(x - 3) = 4/7y
x = (4/7y) + 13
