Eye color is an inherent trait
Think: "Find <span>tan-1(0.577)" means "Find the ANGLE in Quadrant III whose tangent is 0.577. Because the angle is in QIII, both the opp side and the adj side are negative. Here you have four answer choices. The correct answer MUST be within the interval 180 and 270 degrees. Only one of the given answer choices satisfies that criterion. Which one is it?
</span><span>tan-1(0.577) = ?</span>
Answer:
785 acres
Step-by-step explanation:
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let X represent the random variable amount of corn yield
Assuming the X follows a normal distribution
And we know that the average is dsitributed:
And we are interested on this probability:
For this case we can use the z score formula given by:
If we apply this we got:
And since we have a proportion estimated and we hava a total of 1200 acres the expected to yield more than 180 bushels of corn per acre would be:
And if we round up this amount we got and that would be the best option for this case.
You do 150/6 = 500/x
150x = 3000
Means x = 20
