Answer:
A) 12.5%
B) 50%
C) 50%
Step-by-step explanation:
For A, 7 is one of the 8 possibilities (1/8). 1/8 of 100 is 12.5, so your chance of spinning a 7 is 12.5%
For B, even numbers are 4/8 or 1/2 of your options. 1/2 of 100 is 50, so your chance of spinning an even number is 50%
For C, there are 4 out of 8 numbers that are prime (2,3,5, & 7).
4/8 or 1/2 of 100 is 50, so your chance of spinning a prime number is 50%
hope this helps

Answer:
<h2>
63° or 173°</h2>
Step-by-step explanation:
You didn't specify where the point P is so there are two posibilites:
1.
P₁Z is dividing angle OZQ
then:
m∠P₁ZQ = m∠OZQ - m∠OZP₁ = 125° - 62° = 63°
2.
P₂Z is outside angle OZQ
then
m∠P₂ZQ = 360° - (m∠OZQ + m∠OZP₂) = 360° - (125° + 62°) = 173°
Answer:
A is -2
B is 2
C is 4
Step-by-step explanation:
So just replace each letter with these numbers and do the math, hope this helps
