Answer:
x = 16
Step-by-step explanation:
All 3 right triangles are similar, so the lengths of corresponding sides are in proportion.
8√3 / 12 = x / 8√3
12x = (8√3)²
12x = 64 × 3
4x = 64
x = 16
 
        
             
        
        
        
It would be B - 30° celcus. Because when you convert 86° into celcus it becomes 30°. I hoped this helped!
        
             
        
        
        
Answer:
(5.871 `; 6.127)
Step-by-step explanation:
Given :
Mean = 6
Standard deviation. σ = 0.5
Samplr size, n = 100
Zcritical at 99% confidence = 2.58
The confidence interval :
Mean ± margin of error 
Margin of Error = Zcritical * σ / sqrt(n)
Margin of Error = 2.58 * 0.5/sqrt(100) = 0.129
Confidence interval :
Lower boundary = 6.00 - 0.129 = 5.871
Upper boundary = 6.00 + 0.129 = 6.129
(5.871 `; 6.127)
