Answer:
B. 5 hours
Step-by-step explanation:
If the train is going 60mph and we need to find out how long it will be until it is traveling 80mph then we have to do 80-60=20 to figure out how much the speed is changeing. Since every hour the speed increases by 4mph then we have to do how much the train is increasing divided by how much it increases per hour.
20÷4=5
Therefore it will take 5 hours
The answer is 8.5 and also 9-4
we are given with the set of data containing the elements listed above and is asked to find out the standard deviation of the data. SD is used to determine the distance between the points to the best fit line gained from the data. The formula to be followed is the square root of the summation of (x-mean) over n-1. sd is equal to <span>5.13.</span>
Answer:
about 3141.59 cm^3
Step-by-step explanation:
V of cylinder = (pi)(r^2)(h)
radius = 10 cm
height = 10 cm
V = pi x 10^2 x 10
V = 3141.59 cm cubed
