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

Answers

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.

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?

Answers

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.

Answer:

R = ∞

I = (-∞, ∞)

Step-by-step explanation:

Use the ratio test:

lim(n→∞)│aₙ₊₁ / aₙ│

lim(n→∞)│[xⁿ⁺⁶ / (2(n+1)!)] / [xⁿ⁺⁵ / (2n!]│

lim(n→∞)│[xⁿ⁺⁶ / (2(n+1)!)] × (2n! / xⁿ⁺⁵)│

lim(n→∞)│x 2n! / (2(n+1)!)│

lim(n→∞)│n! / (n+1)!││x│

lim(n→∞) (1 / (n+1))│x│

0

The series converges if the limit is less than 1.

The limit is always less than 1, so the radius of convergence is infinite.

So the interval of convergence is (-∞, ∞).

We will find the value of each of the option to see which one is different

a) The opposite of 8

the opposite of 8 is -8

b) The distance between 5 and -3

distance is a scalar value and can NEVER be negative

So, distance = 8

c) The absolute value of 8

the absolute value of 8 is the modulus of 8

|8| = 8

d) The opposite of -8

the opposite of -8 is 8

From the above, we can see that the second, third and fourth options are equal except the first option

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

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?

Answers

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.

In the equation assign each number a letter:

Maximum = -b/2a = -2/2(-0.5) = 2

Minimum = replace x in the equation with the maximum and solve for y:

Maximum and minimum = (2,-3)
