What is the median of the data set? 90 52 78 64 67 88 68 75 75 78 a) 52 b) 78 c) 73.5 d) 75

To find the median of a data set order all the numbers from least to greatest, then find the number in the middle. If there are two numbers in the middle find the mean of the two numbers.

90 52 78 64 67 88 68 75 75 78 ← given

52 64 67 68 75 75 78 78 88 90 ← ordered l to g

75 and 75 are the two numbers in the middle, and since they are the same that means 75 is our median.

D) 75 is your answer.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
