Answer:
13.5
Step-by-step explanation:
Given
tan34° =
( multiply both sides by 20 )
20 × tan34° = x , then
x ≈ 13.5 ( to the nearest tenth )

Answer:
4.53
Step-by-step explanation:
Given the data :
4, 5, 10, 11, 15
The mean = 9
The standard deviation of a sample :
s = √[Σ(x - mean)²/(n-1)]
s = √[((4-9)² + (5-9)²+(10-9)² + (11-9)² + (15-9)²) / (5-1)]
s = √(25+16+1+4+36)/4
s = √20.5
s = 4.527
s = 4.53
He got the right answer, but he kind of did it wrong.
3+x/2=10 simplify both sides of the equation
1/2x+3=10 Subtract 3 from both sides
2*(1/2)=2*7 Multiply both sides by 2
x = 14
