22. SAT scores have a mean of 1518 and a standard deviation of 325. Scores on the ACT have a mean of 21.1 and a standard deviation of 4.8.
a. Which is relatively better: a score of 1030 on the SAT test
or a score of 14.0 on the ACT test? (Hint: First find the z-score of each test)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

If two sides of a triangle are congruent, then the angles opposite those sides are congruent. the converse of the base angles theorem, states that if two angles of a triangle are congruent, then sides opposite those angles are congruent.

Can you explain what u need

The mean is equal to the median according to e2020
