Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
I is the amount of money in Interest
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
<em>Find the interest I</em>

substitute in the formula above
Solve for t
Answer with Step-by-step explanation:
Let speed of one car=x miles/h
Speed of second car=x+8 mi/h
Time,t=2 hours
Distance between two cars=208 miles
We have to find the average speed for each car for 2-hour trip.
Distance=
Distance traveled by one car=2x
Distance traveled by second car=2(x+8)
According to question





Speed of one car=48mph
Speed of second car=48+8=56mph
Using the mean absolute deviation, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.
<h3>What is the mean absolute deviation of a data-set?</h3>
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean absolute deviation is of 1.3 inches, hence, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.
