For every value tht x increases, y decreases by 3
-3x
Then to find the y intercept, look at 0's corresponding value (8)
-3x+8
Answer:
a
The percentage is

b
The probability is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The variance is 
The range consider is 
The value consider in second question is 
Generally the standard deviation is mathematically represented as

substituting value

The percentage of a cucumber give the crop amount between 778 and 834 kg is mathematically represented as

Generally 
So


From the z-table the value for 
and
So


The percentage is

The probability of cucumber give the crop exceed 900 kg is mathematically represented as

substituting values


From the z-table the value for
