Answer: 95.64% of the values will be below 212.5 in our set of data.
First, determine the z-score for the expected value of 212.5. The z-score is the number of standard deviations that it is above or below the mean.
(212.5 - 192.3) / 11.8 = 1.71
A score of 212.5 is 1.71 standard deviations above the mean. Now, use a table to find the probability for a z-score of 1.71. The percent is 95.64%.
Answer:
I can tell you that it is not A. I can't tell what the other tables say because the image is cropped. If you could please fix the image, I will be able to help you.
Here's an example: If you have -9 and it asks for the absolute value of it, it means the opposite. The absolute value of -9 is positive 9.
Answer:
The given statement is true because the person they did their steps correctly
a) Locate a point C so that ABC is a right triangle with m ACB ∠ = ° 90 and the measure of one of the acute angles in the triangle is 45° .
b) Locate a point D so that ABD is a right triangle with m ADB ∠ = ° 90 and
the measure of one of the acute angles in the triangle is30° .
c) Locate a point E so that ABE is a right triangle with m AEB ∠ = ° 90 and
the measure of one of the acute angles in the triangle is15° .
d) Find the distance between point C and the midpoint of segment AB .
Repeat with points D and E.
e) Suppose F is a point on the graph so that ABF is a right triangle
withm AFB ∠ =° 90 . Make a conjecture about the point F.
