The rate of travel here is in mph - "miles per hour".
That just means how many miles you can travel in one hour. In this problem, you're given 15 hours, and the distance they travel within those 15 hours.
Therefore, you should divide both the number of miles and the number of hours by 15 to find out how far they can travel in 1 hour.
735 ÷ 15 = 49 miles
15 ÷ 15 = 1 hour
Their average rate of travel was 49 miles in 1 hour, which is 49 mph.
For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial gain
b: growth rate
t: time
Substituting values we have:
y = 46000 * (1.10) ^ t
For the year 7 we have:
y = 46000 * (1.10) ^ 7
y = 89640.9866
Answer:
her total earning at the end of 7 years are:
y = 89640.9866 $
The normal distribution is also known as the Gaussian distribution. The correct option is D, while the z-score is -2.29.
<h3>What is Normal Distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Since the normal distribution is symmetrical about the mean. Therefore, 0.89 area from the left will be equal to 0.11 area from the right. Therefore, the correct option is D, while the z-score is -2.29.
