A because if you were doing it on a quadrant or a number line I think that would be the answer! Not 100% sorry
Answer:
A, They are congruent angles.
Step-by-step explanation:
The circumference follows the formula
C= 2 (pi)R
R is the radius which is half the diameter when we put this into the equation we get
C = 2 (pi)(4.5)
C=28.274334
We want to find the sample size n such that
Pr[|µ - 101| < 5] = 0.98
where µ is ... some mean. It can be the mean for either the true population or the sample. It's unclear which is which from the given info, but that's not actually important.
In the inequality, divide both sides by the standard error, σ/√n = 16/√n :
Pr[|µ - 101|/(16/√n) < 5/(16/√n)] = 0.98
Use a lookup table to find the z-score corresponding to 0.98 :
⇒ 5/(16/√n) ≈ 2.05375
Solve for n :
⇒ n ≈ 43.1911 ≈ 44
(n) is the set of <u>odd</u> natural numbers greater than 0.
