Consider the code below using the French Fries data in long format

fries_long %>% summarise(rating = mean(rating)).

Pipes will maximise the need for

local variables and function definitions.

What is mutate in R? Choose the most appropriate answer.

What is true about pipe "%>%" operator in R? Select all that applies.

What does the following graph regarding tuberculosis tell us? Select all that apply.

Which of these represents the correct output of this code: ydm(".2020/-12.24")

To create a scatter plot using ggplot2 package, you need to: 1) define a dataset using ggplot function 2) Specify your geometric layer 3) Map aesthetics attributes Remember that steps 2 and 3 are interchangeable. Choose the appropriate ggplot function(s) to complete the task above.

Solve, in big-θ, the following recurrence relation

T(n) = 4 * T(n/4) + c, where n >= 4
T(n) = b, where n = 1

for constants b and c.

Given the following pseudocode, derive the recurrence relation that represents its time complexity. 

def fibonacci(n):
    if (n==0 or n==1):
        return n 
    return fibonacci(n - 1) + fibonacci(n - 2)

Let b and c represent constant values. What is the base case and recurrence step?
