4 3/4= 19/4=4.75 its a terminating decimal
Answer:
Step-by-step explanation:
total time is 5 hr and total distance is 72 nautical miles
Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.
we are given
we can find x , y and z
now, we can use arc length formula
now, we can find derivative
now, we can plug values
and we get
