1) from smaller to higher:
1,5,11,11,17
2) find the mean
<span>1 + 5 + 11 + 11 + 17 = </span><span>45
</span>mean = 45/5 = 9
Variance = Σ(x- mean)²/(N-1)
[(1-9)² + (5-9)²+(11-9)² + (11-9)²+ (17-9)² ]'(5-1) = 38
Variance = 38
Responder:
2³
5⁴
10³
a^6
Explicação passo a passo:
Quando um certo valor é multiplicado repetidamente,
Por exemplo,
a * a * a * a = a⁴ (a multiplicado 4 vezes)
Por isso,
2 x 2 x 2 = 2³
5 x 5 x 5 x 5 = 5⁴
10 x 10 x 10 = 10³
a x a x a x a x a x a = a^6
Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.
