His error was that he did not flip the inequality sign.
31<5x+6
25<-5x
-5>x
The z scores corresponding to the mean weight of a rotten apple relative to the apples from either orchard are, respectively,


The mean for the standard normal distribution is 0, which means that z scores closer to 0 represent data points that are more likely to occur. Therefore it's reasonable to believe that rotten apples occur more often in shipments from Zippy's.
f(4)= 4^2 - 1 = 15
g(f(4)) = g(15) = 2(15) = 30
Hope this helps!
Answer:
{x | x ≤ -8}
Step-by-step explanation:
-7x ≥ 56
Divide each side by -7, remembering to flip the inequality since we are dividing by a negative
-7x/-7 ≤ 56/-7
x ≤ -8
