Answer:
3^4, she raised it to the 4th power
Step-by-step explanation:
3^x+19=100
-19
3^x=81
We can make a table now to find what power of three = 81
Powers of three table
3^1=3 3^2=9 3^3=27 3^4=81
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 .
Adults pay = $33.60
Children pay = $16.80 (it's half price but if they take a round trip it's double the price. Therefore it's $16.80) then multiply both by two and add them together.
2 ($33.60+$16.80) = $100.80
Answer: square 4

Translation (x+5, y-3) is the movement of LMNP five units to the right and three units down
Hope this helps!!!
If 44/p is the same as 11/s, then we should look at what 11/s is scaled by to get 44/p, if that makes sense. So, we’d take 44/11 to get 4, therefore p=4. This also means that s=1, because 44/4=11/1
