Answer:
9.18% probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean  and standard deviation
 and standard deviation  , the zscore of a measure X is given by:
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What is the probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated?
This is 1 subtracted by the pvalue of Z when X = 16. So



 has a pvalue of 0.9082
 has a pvalue of 0.9082
1 - 0.9082 = 0.0918
9.18% probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated
 
        
             
        
        
        
Answer:
Y=-5/3x
Step-by-step explanation:
Use the slope formula and slope-intercept form y=mx+b to find the equation.
 
        
             
        
        
        
888 + 444 + 333 + 666 = 2331 / 7 = 3
3 * 222 = 666
There are 666 of the plants 
I hope this helps :)

Answer:
 Option A is correct that is 
Step-by-step explanation:
We have been given a formula 

We will put values of n in  
 
when n=2 we get 
 
 
 
 
 
 
 
 
when n=3
 
 
 
 
 
 
Therefore, Option A is correct that is
