First you would do 36/4 and get 9 then you would subtract the exponents 5-3 and the answer would be
9x to the second power
Answer: B. 461 acres
Step-by-step explanation:
Given : In an agricultural study, the average amount of corn yield is normally distributed with a mean of 185.2 bushels of corn per acre, with a standard deviation of 23.5 bushels of corn.
i.e. 
Let x denotes the amount of corn yield.
Now, the probability that the amount of corn yield is more than 190 bushels of corn per acre.

[Formula :
]
[∵ P(Z>z)=1-P(Z<z)]
[using z-value calculator or table]

Now, If a study included 1100 acres then the expected number to yield more than 190 bushels of corn per acre :-

hence, the correct answer is B. 461 acres .
Answer:
100 is grace's initial amount. w is how much of the substance is being decrased each week. in ryan's equation, 1 is 100% of the substance, so the initial amount, and 0.4 is the amount that is being decreased.
