Licemer1 [7]

Answer:

2

Step-by-step explanation:

Hello!

1) Firstly, let's enlist all the coordinate, (x,y) points to visualize it better.:

(2,4)\\(3,0)\\(-1,-1)\\(4,3)

2) Check the pair of sets for this function below. The Domain Set, on the left. The Range set, on the right. This Diagram shows a one to one (injective and surjective) function . Since its element of the Range is 4, then its corresponding one on the Domain set is 2.

A sample of weights of defensive tackles on Big 10 football teams are: Johnson, 202 pounds; Patrick, 215 pounds; Junior, 207 pou
ExtremeBDS [4]

Answer:

the sample standard deviation is 4.926 pounds

Step-by-step explanation:

the sample standard deviation s is defined as

s =√[ 1/(n-1) ∑ ( x- m)²]  for x=1 to x=n

where

n= sample size = 10

x= weights of defensive tackles

m= sample mean

m= 1/n ∑ x*  for x=1 to x=n

then

m= 1/10 (202 + 215... +208) = 209.66 pounds

thus

s =√[ 1/(10-1) ∑ ( x- m)²] = √[ 1/(10-1) [ ( 202 - 209.66 )² + ( 215 - 209.66 )² +  ( 28 - 209.66 )² ] ] = 4.926 pounds

then the sample standard deviation is 4.926 pounds
