Answer:
The box has 11 layers
Step-by-step explanation:
Since there are 363 balls and each layer has 33 balls, we have to divide 363 by 33.
363÷33= 11
So, there will be 11 layers in the box.

andom variable X has CDF given as follows. Find the PMF of X.Find the PMF of X, and confirm that it is a valid PMF.
Complete Question
Random variable X has CDF given as follows
[tex]F(x)_x = \left \{ {{{{{{{ 0 \ \ \ \ \ \ \ \ \ \ x < 0} \atop {\frac{8}{33}} \ \ \ \ \ \ 0 \le x \le 1} \atop{ \frac{5}{11} }\ \ \ \ \ 1 \le x \le 2 } \atop {\frac{7}{11} } \ \ \ \ \ \ 2 \le x \le 3} \atop{ \frac{26}{33} }\ \ \ \ \ 3 \le x \le 4 }\atop {\frac{10}{11} } \ \ \ \ \ \ 4 \le x \le 5} \atop{ 1}\ \ \ \ \ \ \ \ 5 \le x } \right.[/tex]
Find the PMF of X.Find the PMF of X, and confirm that it is a valid PMF.
Answer:
Generally the PMF is
X 0 1 2 3 4 5
P(X = x) [tex]\frac{8}{33}[/tex] [tex]\frac{7}{33}[/tex] [tex]\frac{2}{11}[/tex] [tex]\frac{5}{33}[/tex] [tex]\frac{4}{33}[/tex] [tex]\frac{1}{11}[/tex]
Generally to prove the validity of the PMF we add the probabilities , if it is equal to 1 then the PMF is valid otherwise , the PMF is not valid
So
[tex]\sum P(X = x) = \frac{8}{33} + \frac{7}{33} + \frac{2}{11} + \frac{5}{33} + \frac{4}{33}+ \frac{1}{11}[/tex]
[tex]\sum P(X = x) =1[/tex]
Hence the PMF is valid
Step-by-step explanation:
Generally the probability of X = 0 is evaluated as
[tex]P(0) = F(0) \ \ (for \ x \le 0) - F(0) \ ( for \ x < 0)[/tex]
=> [tex]P(0) = \frac{8}{33} - 0[/tex]
=> [tex]P(0) = \frac{8}{33}[/tex]
Generally the probability of X = 1 is evaluated as
[tex]P(1) = F(1) \ \ (for \ 1 \le 0) - F(1) \ ( for \ x < 1)[/tex]
=> [tex]P(1) = \frac{5}{11} - \frac{8}{33}[/tex]
=> [tex]P(1) = \frac{7}{33}[/tex]
Generally the probability of X = 2 is evaluated as
[tex]P(2) = F(2) \ \ (for \ 2 \le x ) - F(2) \ ( for \ x < 2)[/tex]
=> [tex]P(2) = \frac{7}{11} - \frac{5}{11}[/tex]
=> [tex]P(2) = \frac{2}{11}[/tex]
Generally the probability of X = 3 is evaluated as
[tex]P(3) = F(3) \ \ (for \ 3 \le x ) - F(3) \ ( for \ x < 3)[/tex]
=> [tex]P(3) = \frac{26}{33} - \frac{7}{11}[/tex]
=> [tex]P(3) = \frac{5}{33}[/tex]
Generally the probability of X = 4 is evaluated as
[tex]P(4) = F(4) \ \ (for \ 4 \le x ) - F(4) \ ( for \ x < 4)[/tex]
=> [tex]P(4) = \frac{10}{11} - \frac{26}{33}[/tex]
=> [tex]P(4) = \frac{4}{33}[/tex]
Generally the probability of X = 5 is evaluated as
[tex]P(5) = F(5) \ \ (for \ 5 \le x ) - F(5) \ ( for \ x < 5)[/tex]
=> [tex]P(5) = 1- \frac{10}{11}[/tex]
=> [tex]P(5) = \frac{1}{11}[/tex]
Generally the PMF is
X 0 1 2 3 4 5
P(X = x) [tex]\frac{8}{33}[/tex] [tex]\frac{7}{33}[/tex] [tex]\frac{2}{11}[/tex] [tex]\frac{5}{33}[/tex] [tex]\frac{4}{33}[/tex] [tex]\frac{1}{11}[/tex]
Generally to prove the validity of the PMF we add the probabilities , if it is equal to 1 then the PMF is valid otherwise , the PMF is not valid
So
[tex]\sum P(X = x) = \frac{8}{33} + \frac{7}{33} + \frac{2}{11} + \frac{5}{33} + \frac{4}{33}+ \frac{1}{11}[/tex]
[tex]\sum P(X = x) =1[/tex]
Hence the PMF is valid

Answer:
El resultado es:
[tex]\displaystyle \frac{29}{56}[/tex]
Step-by-step explanation:
Suma de fracciones
Vamos a sumar:
[tex]\displaystyle \frac{3}{8}+\frac{1}{7}[/tex]
Debemos encontrar el mínimo común múltiplo (MCM) entre los denominadores, en este caso, 7 y 8.
Descomponemos en factores primos:
7=7
8=2*2*2
Se toman los comunes y no comunes con máximo exponente, así que el MCM es 7*8=56.
Se procede a dividir el MCM entre cada denominador y al multiplicarlo por su numerador correspondiente:
[tex]\displaystyle \frac{3}{8}+\frac{1}{7}=\frac{3*7+1*8}{56}=\frac{29}{56}[/tex]
El resultado es:
[tex]\displaystyle \frac{29}{56}[/tex]
Suppose Amanda LaCount is scheduled to dance 21 times in one month. If the ratio of dances completed to dances remaining is 3:4, how many dances has Amanda already performed?
Answer:
9
Step-by-step explanation:
if you add up the amount of dances she has to do, it equals 7. then you divide 21 by 7, which equals 3. then, you have to find the amount of dances she has already done, which would be 3 × 3 which equals 9.

In Algebra, we learn about functions of various types. These functions are often seen in a progression from least complicated (linear) to most complicated (piecewise with nonlinear parts). And then there are other types of functions in-between: exponential, quadratic, polynomial, radical, and logarithmic. But with all their differences and unique properties, these share a common trait of being functions that we can graph in a coordinate plane.
What are some other things you can observe to have that same quality of functions: unique, but sharing a common trait or purpose?
Somethings I can observe that have the same quality is that all functions only have one outcome for a given input. A vertical line will never meet the graph more than once. No X values are used more than once. A function will have either no horizontal asymptote or just one asymptote. These are some common traits that all functions have.
We can see that all functions have the one outcome for one value of x if we can see all the functions carefully.
What is a function?
A function is a relation in which each value of x corresponds to some value of y.
How to determine the features of a function?
When we see some functions, they have the same quality of giving one result for one input. The quality of the graph of all functions is that the vertical line cannot meet the axis twice.

at springtown café, 5/9 of the customers left a large tip. In contrast, 3/10 of the customers at Allenville bistro left a large til. Which restaurant had a greater fraction of customers who left a large tip? please help
Answer:
Springtown Cafe
Step-by-step explanation:
If you want to be sure, find a common denominator. 9 and 10 are the denominators of each fraction. Find the multiples of each (9's multiples would be 9, 18, 27, etc.) and find a common multiple between the two. In this case, it would be 90. Multiply the denominator to get the common denominator. 9 x 10 = 90, 10 x 9 = 90. Remember to multiply both the top and bottom.
5/9 = 50/90
3/10 = 27/90
Now, we can clearly see that 5/9 is larger than 3/10.
So, Springtown cafe has a greater fraction of customers who left good tips.
SHOW WORK: h(x)= -4x+4, what is x when h(x)=-20 ? *
Answer:
x=6
Step-by-step explanation:
h(x)=-20 is the same as saying y=-20, so you would substitute h(x) with -20 and solve the equation from there.
[tex]-20=-4x+4[/tex]

minimum or maximum value of f(x)=−0.5x2+2x−5.
In the equation assign each number a letter:
A = -0.5, b = 2 and c = -5
Maximum = -b/2a = -2/2(-0.5) = 2
Minimum = replace x in the equation with the maximum and solve for y:
-0.5(2)^2 +2(2) -5 = -3
Maximum and minimum = (2,-3)

The contractor in charge of organizing your pool complex project has informed you that he has found two landscape companies willing to do the work. The 1st company says they can get the entire job done in 72 hours. The 2nd company says they can get the job done in 24 hours. You've decided that it would be best if both companies worked together to get the job done quicker! How many hours would it take to complete the landscaping job if the two companies worked together?
Answer:
18 hours
Step-by-step explanation:
Time taken to complete the job by 1st company = [tex]72\ \text{hours}[/tex]
Time taken to complete the job by 2nd company = [tex]24\ \text{hours}[/tex]
The job completed in 1 hour by 1st company = [tex]\dfrac{1}{72}\ \text{job}[/tex]
The job completed in 1 hour by 2nd company = [tex]\dfrac{1}{24}\ \text{job}[/tex]
The amount of job completed in 1 hour if they both work together[tex]1\ \text{hour}=\dfrac{1}{72}+\dfrac{1}{24}=\dfrac{1}{18}\ \text{job}\\\Rightarrow 1\ \text{job}=\dfrac{18}{1}\ \text{hours}=18\ \text{hours}[/tex]
So, if both companies work together it will take 18 hours to finish the job.
