Step-by-step explanation:
In the normal distribution curve, the mean is in the middle and each line to the left and to the right of that mean represent 1- and 1+ the standard deviation. If our mean is 400, then 400 + 50 = 450; 450 + 50 = 500; 500 + 50 = 550. Going from the mean to the left, we subtract the standard deviation and 400 - 50 = 350; 350 - 50 = 300; 300 - 50 = 250. We are interested in the range that falls between 350 and 450 as a percentage. That range represents the two middle sections, each containing 34% of the data. So the total percentage of response times is 68%. We are looking then for 68% of the 144 emergency response times in town. .68(144) = 97.92 or 98 emergencies that have response times of between 350 and 450 seconds.
Answer:
The velocity is the speed in a given direction hence the units are the same as that of speed, m/s. Thus the answer is 30 m/s.

The formula for the area of a paralellogram is:
bh=a
Where
b is the base (15 for this)
h is the height (5 for this)
and a is the area
Let's sub our values into the formula
Now solve
