Pretty sure the mean is 5
X=70, y=55
The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.
Then use the triangle angle sum theorem and set the equation to 180.
55+55+x=180
110+x=180
x=70
The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.

The answer is B. -7
Step-by-step explanation:
the -7 cancels out the +7 which makes it neutral
Since it went 8 floors in 6 seconds you divide. 8/6 is 1.333 or 1 1/3 floors per second. Hope this helps.

2.) 0; it represents no correlation between x and y
This is because no matter the age they could answer 17 questions
Hope this helps!
