The angle turned is obtained as 3.77 rads.
<h3>What is the angle of rotation?</h3>
We have the following information about the disk;
velocity 1= 7200 RPM
velocity 2 = 0 RPM
time taken = 0.01 seconds
We must convert from RPM to rad/s using the relation;
2π·7200/60 = 754 rad/s
Using;
θ = ωavt
θ = (754 rad/s + 0 rad/s)/2 * 0.01 seconds
θ = 3.77 rads

i dont have it we can talk here tho:)
Explanation:
Using the normal approximation to the binomial, it is found that there is a 0.0107 = 1.07% probability that more than 30 are single.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with
.
In this problem, the proportion and the sample size are, respectively, p = 0.22 and n = 200, hence:


The probability that more than 30 are single, using continuity correction, is P(X > 30.5), which is <u>1 subtracted by the p-value of Z when X = 30.5</u>, hence:


Z = -2.3
Z = -2.3 has a p-value of 0.0107.
0.0107 = 1.07% probability that more than 30 are single.
