Suppose the following data set represents the starting salaries for the population of teachers from seven states: $41,027, $35,901, $31,159, $33,664, $35,166,$39,338, $32,691
a) calculate the mean of the data set
b) calculate the 5 number summary
c) calculate the standard deviation of this data set

See explanation

Step-by-step explanation:

Arrange the salaries $41,027, $35,901, $31,159, $33,664, $35,166, $39,338, $32,691 in ascending order:

$31,159, $32,691, $33,664, $35,166, $35,901, $39,338, $41,027

A) The mean salary (to the nearest dollar) is

B) Minimum

Median

Maximum

C) The standard deviation of this data set can be calculated using formula

First, find

Now,

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
