Answer:
38%
Step-by-step explanation:
set up proportions
114 x
----- = -------
300 100
cross multiply
11400 = 300x
divide
x= 38
Mean basically means average/ all the numbers added together divided by the amount of numbers given to us
So all the numbers added up will equal to 51 (-5+-3+-1+6+6+9+9+10+10+10) now divide that by the number of of numbers me given to us which is 10 so
51/10= 5.1
Mean=5.1
Answer:
a = 30 degrees; b = 60 degrees; and c = 105 degrees.
Step-by-step explanation:
Angle a and the 30 degree angle are vertical angles and thus are equal.
Since the interior angles of a triangle always add up to 180 degrees, 30 + b + 90 degrees = 180 degrees, so that b must be 60 degrees.
Angle c and the 75 degree angle are straight angles, and so their sum must be 180 degrees. Thus, c = 105 degrees.
