Answer:
Step-by-step explanation:
Given data:
standard deviation is
As distribution is normal in shape and values are symmetrical
The standard deviation rule says that 95% of observation lies between the second standard deviation of the mean
so, approximately only 5% of observation lies outside the interval and normal shape is symmetric. hence approximately 0.15% of observation lies above the interval
almost 0.15% of students spent more amount is 529
Answer:Hi, the correct answer is .
Step-by-step explanation:
As you are being asked for rate and the importat value is the number of calories consumed. We need to simplify the fraction . Then we simplify.
Note that 480 is divisible by 3 and 9 as well. 480/3 = 160 and 9/3 = 3. Therefore, 480/9 = 160/3.
Using the relation between velocity, distance and time, it is found that t = 3 hours.
<h3>What is the relation between velocity, distance and time?</h3>Velocity is <u>distance divided by time</u>, hence:
For this problem, the parameters are given as follows:
d = 15 miles, v = 5 mph
Hence the time in hours is found as follows:
5t = 15
t = 15/5
t = 3 hours.
