First you need to graph the coordinate points to see the triangle.
Then you need to drop lines down on the graph to form right triangles and use Pythagorean Theorem.
The line of points -5,-1 and -2,3 measures 5 using Pythagorean theorem.
The line of points 6,-3 and -5,1 measures √125
The line of points 6,-3 and -2,3 measures 10 using Pythagorean theorem.
So...
5 + 10 = 15
15 + √125
The line needs to start at the 0 it can’t be off the 0
I think it’s the last one
I’m not sure
Sorry
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 .
