Answer:
13,10,16, an 11
Step-by-step explanation:
Average = Sum of numbers/# of numbers
The sum is 423
The # of numbers = 50
Sum/# = 423/50, making the average 8.46
The only numbers above 8.46 in the data set are:
13,10,16, an 11
Answer:
x = - 
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
The radius of a unit circle is r = 1
substitute (x, -
) into the equation and solve for x
x² + (-
)² = 1²
x² +
= 1 ( subtract
from both sides )
x² = 1 -
=
( take square root of both sides )
x = ±
= ± 
since the point is in the 3rd quadrant then x < 0
x = - 
Answer: The equation doesn't look right, it's either there's too many symbols or you need to switch some things around.
