Answer:  mean=26 , median=24

Step-by-step explanation:

Mean=Sum of all values/number of values

mean= 30+39+24+ 19+18/5

         = 130/5

 mean=26

Median

arrange data in order

    18,19,24,20,39

In the case of ungrouped odd-numbered data, the number that  divided data into 2 equal parts is called the median.

so median=24

And angle measures 54° more than the measure of its complementary angle what is the measure of each angle
Mashutka [201]
Answer:
The measure of the angles are 72 degrees and 18 degrees
Step-by-step explanation:
we know that
If two angles are complementary, then their sum is equal to 90 degrees
Let
x -----> the measure of an angle
y-----> the measure of he other angle
we know that
x+y=90 -----> y=90-x -----> equation A
x=y+54 ----> equation B
substitute equation B in equation A and solve for y
y=90-(y+54)
y=90-y-54
2y=36
y=18°
Find the value of x
x=y+54 -----> x=18+54=72°
therefore
The measure of the angles are 72 degrees and 18 degrees
