Answer:
A. Twice the radius, d = 2r
Step-by-step explanation:
The diameter is a line that splits a circle in half, while the radius is only half of that.
Answer: A
<u>Step-by-step explanation:</u>
≅ 
⇒ ∠XOY ≅ ∠ZOY
≅ 
since they are both a radius
≅ based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So, 
≅ 
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
Answer:
Step-by-step explanation:
1)Population of Interest : All UC Berkeley Undergraduates
Sample : 129 UC Berkeley Undergraduates
2)
Can the results of the study be generalized to the population of interest?
No, because the sample is not representative of the population since it consists of only UC Berkeley undergraduates.
3)
No, because the the study is observational.
