Hello from MrBillDoesMath!
Answer:
x = 19, y = 36
Discussion:
x + 3 = 22     (*)
2x - y = 2      (**)
Subtract 3 from both sides of (*)
x + 3 -3 = 22 = 3 = 19  =>
x = 19
Substitute x= 19 in (**)
2(19) - y = 2 =>
38 - y = 2 =>           (add y to both sides)
38 -y + y = 2 + y =>
38 = 2 + y  =>         (subtract 2 from both sides)
38 -2 = 2 -2 + y =>
36 = y

Answer:
Step-by-step explanation:
it’s going to be (4,-2)
 
        
             
        
        
        
Because There are 3 feet in 1 yard, so 3 feet and 1 yard are the same thing, hence a 1:1 ratio.
        
             
        
        
        
Since the sample is greater than 10, we can approximate this binomial problem with a normal distribution.
First, calculate the z-score:
z = (x - μ) / σ = (37000 - 36000) / 7000 = 0.143
The probability P(x > 37000$) = 1 - P(<span>x < 37000$), 
therefore we need to look up at a normal distribution table in order to find 
P(z < 0.143) = 0.55567 
And 
</span>P(x > 37000$) = 1 - <span>0.55567 = 0.44433
Hence, there is a 44.4% probability that </span><span>the sample mean is greater than $37,000.</span>
