Answer:

Median = 31.5

Mean  = 32.25

Step-by-step explanation:

Number of data = 8

Ascending order:

    30 , 30 , 31 , 31 , 32 ,  33 , 35, 36

Median = Average of 4th and 5th term

             = (31 + 32) / 2

              = 63/2

              = 31.5

Mean = Sum of all the observations /number of observations

         = (31 + 32 + 36 +31 + 30 + 35 + 33 +30) / 8

         = 258/8  

         = 32.25

Which of the following systems of Inequalities would produce the region indicated on the graph below?
Fed [463]
The line rising to the right has equation y = x + 2
and the  other one has equation y =  -x + 4

the lines are solid so the inequalities will be <= or >=

in both case  the shading is below so the sign is <=

also x and Y values are both positive  
so the answer is choice  C

Write an equation to represent the following statement. 33 is 15 less than k. ______ Solve for k. K= _____
Evgesh-ka [11]

Answer:

in the first box put k-15=33

in the second box put k=48

Step-by-step explanation:

if you look at what it says, it says 33 is 15 less than k. so we know that we are going to have 33 on one side and k and 15 on the other. it also says 15 less than k, so that would be k-15

33=k-15 or k-15=33

now we have to solve this. add 15 to each side to cancel out the -15

that gives you k=48

If y varies directly as x and y=14 when x= 3.5 what is the constant of variation
gulaghasi [49]

Hey there! Direct variation, a concept commonly applied to linear equations.

The constant of variation is a concept which simply refers to the change in y, based on the change in x. If this change is constant, then it is a constant of variation.


You can find the constant of variation (usually referred to as 'k') by dividing any point's y-value by its x-value.


In this instance, we have the point (3.5, 14)

14 / 3.5 = 4


The constant of variation for this equation would be 4.
