40.2 - 13.7 = 26.5
26.5 / 13.7 * 100 = 193.43
answer
193%
The probability that a randomly selected individual will have a waiting time between 16 and 44 minutes is 93.72%.
Given mean of 30 minutes and standard deviation of 7.5 minutes.
In a set with mean d and standard deviation d. , the z score is given as:
Z=(X-d)/s.
where d is sample mean and s is standard deviation.
We have to calculate z score and then p value from normal distribution table.
We have been given d=30, s=7.5
p value of Z when X=44 subtracted by the p value of Z when X=16.
When X=44,
Z=(44-30)/7.5
=14/7.5
=1.87
P value=0.9686
When X=16
Z=(16-30)/7.5
=-1.87
P Value=0.0314.
Required probability is =0.9686-0.0314
=0.9372
=93.72%
Hence the probability that a randomly selected individual will have a waiting time between 16 and 44 minutes is 93.72%.

You haven't given any options.
there are infinite numbers which are at a distance of √17 from origin.
Example: 4+i, 1+4i, 17i, 3+2√2i, 4-i etc
The correct answer is
c) Neither person is correct because light does not change frequency when it travels through different media
we have given that The column on the right is labeled speed of light in meters per second and are all times 10 Superscript 8 Baseline with entries 2. 25, 2. 99, 1. 97, 1. 24.
<h3>What happened when light travels through the different media?</h3>
light changes both wavelength and speed when it travels through different media, but the frequency remains the same
light changes both wavelength and speed when it travels through different media, but the frequency remains the same.
Therefore the option c is correct that
Neither person is correct because light does not change frequency when it travels through different media
