beks73 [17]

Answer:

CV for statistics exam = 15%

CV for calculus exam = 19%

Since the CV for calculus exam is higher, it has a greater spread relative to the mean than the statistics exam.

Step-by-step explanation:

To find coefficient variation we use the formula:

CV = (SD/mean) * 100

CV for the statistics exam:

where; SD= 5

mean= 75

CV = ( 5/75) *100

= 0.15 or 15%

CV for calculus exam

SD = 11

Mean= 58

CV= (11 /58) * 100

= 0.19 or 19%

Given the table of values below, which of the following ordered pairs are found on the graph of the inverse function? A. (-2, -1
Ainat [17]

Given:

The of values of a function.

To find:

The ordered pairs that are found on the graph of the inverse function.

Solution:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

Then its inverse function is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

From the given table it is clear that, the ordered pairs of the function f(x) are :

\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}

So, ordered pairs of the inverse function are :

\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}

Therefore, the correct option is B.
