Answer:
x = 10
Step-by-step explanation:
By looking at the picture, I can tell the angle of the 3x is also 30 degrees.
This means 3x = 30.
When you solve for x by dividing each side by 3, you result with the answer of x = 10.
To check you work, plug in 10 for x to recieve 30 degrees again.
 
        
             
        
        
        
Answer is given below 
Step-by-step explanation:
given data 
average length of all 1015 fishes = 98.06 mm
randomly selects 50 fishes average length = 101.04 mm
solution
- When we get here, we mean to measure, so here we measure a fish in a square lake.
 - And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
 - parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
 - statics is selct of individual in sample so statistic is average length of random sected so fish in square lake 
 
 
        
             
        
        
        
If it starts with 0.12 it is false.
But if it starts with 0.009 it is true.
