Mean
add up numbers and divide by how many there are
(1+1+5+3+6+6)/7=3 and 2/3
Answer:
A. I can't quite see the question, but I'm pretty sure it's A
Step-by-step explanation:
Sin(A) = 1/3
Sin^2(A) + Cos^2(A) = 1
(1/3)^2 + cos^2(A) = 1
1/9 + cos^2(A) = 1
cos^2(A) = 1 - 1/9
cos^2(A) = 8/9
cos(A) = √(8/9)
√8 = √(2 * 2 * 2) = 2√2
√9 = 3
cos(A) = 2√2/3
Answer: D = x'10 − 10x'8 + 40x'6 − 80x'4 + 80x'2 − 32

Answer:
z=34
Step-by-step explanation:
2 + 8 - z = -24
add
10-z = -24
subtract 10 from each side
10-z-10 = -24-10
-z = -34
multiply by -1
-1*-z = -34 * -1
z = 34
Answer:
5 units
Step-by-step explanation:
The radius is the distance from the centre of the circle to a point on the circumference.
Use the distance formula to calculate the radius r
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
r = 
=

= 5
