She should use a computer to select 30 students at random then ask which ones play chess. The other options could produce more skewed results.
SOLUTION
Consider the property, opposite angle of a cyclic quadrilateral are supplementary
hence

Recall that

Hnece, we have that

Then

Hence
x=17
Since

Therefore
The measure of angle NOP is 68⁰
Answer; 68⁰ (The fourth Option )
Answer:
x= 4.24
y= 4.24
Step-by-step explanation:
1) I began by analyzing the given number, which in this case is the hypotenuse. I know the hypotenuse is equal to x√2.
2) I divided 6 by √2, which gave me 4.24.
Answer:
y = (1/2)x - (15/2)
Step-by-step explanation:
goal: to rearrange the expression such that it is in the form
y = f(x); where f(x) is an expression in terms of x
given:
x - 2y = 15 (subtract x from both sides)
-2y = 15 - x (multiply both sides by -1 to make left side positive)
2y = -15 + x (divide both sides by 2 and rearrange)
y = (1/2)x - (15/2)
I would love to help but what’s the question to this problem
