Answer:
z ≈ 145.62
Step-by-step explanation:
using the sine ratio in the right triangle
sin18° = 
= 
( multiply both sides by z )
z × sin18° = 45 ( divide both sides by sin18° )
z = 
≈ 145.62 ( to the nearest hundredth )
Answer:
I think the answer is C but I'm not 100% sure
To solve this problem, we make use of the z statistic. The
formula for z score is:
z = (x – μ) / s
where,
x = is the sample score = 21 or higher
μ = the population mean = 20.8
s = the standard deviation = 4.8
Solving for the z score:
z = (21 – 20.8) / 4.8
z = 0.0417
Next step to do is to find for the p value using the
standard distribution tables at z = 0.04. Since we are looking for the
probability of getting 21 or higher, therefore this is a right tailed test,
hence
p = 0.516

21 or greater.</span>
