(350-126)/(5-3)=112m/s

This is the average speed in the time from 3 to 5 seconds...

dd/dt    98,126,154
d2d/dt2   28,28

She actually had a constant acceleration over the entire time period.

The function for that table is:

d(t)=14t^2  

Her actual velocity at any point is v(t)=28t  (you can see that if you take the mid point of the interval, 4s, you will get the average velocity found earlier)

Nadusha1986 [10]

Answer:

The difference between the pulse rate of 36 beats per minute and the mean pulse rate for females is 42 beats per minute.

Step-by-step explanation:

We are given that for a data set of the pulse rates of adult females, the lowest pulse rate is 36 beats per minute, the mean of the listed pulse rate is x = 78.0 beats per minute, and their standard deviation is s = 13.7 beats per minute.

The mean pulse rate for females = \bar x = 78.0 beats per minute

The standard deviation of the listed pulse rate = s = 13.7 beats per minute

The given pulse rate is = 36 beats per minute

So, the difference between the pulse rate of 36 beats per minute and the mean pulse rate for females is given by;

              = \bar x - 36

              = 78 - 36 = 42 beats per minute

Hence, the required difference is 42 beats per minute.
