The mean of a dataset is 20 and the standard deviation is 7.

A closed interval notation is a way of representing a set of numbers that includes all the numbers in the interval between two given numbers. In this notation, the numbers at the endpoints of the interval are included in the set. The notation for a closed interval is typically of the form [a,b], where a and b are the endpoints of the interval.

Step 1: Finding the second derivative. To find the inflection points of f , we need to use f ″ : f ′ ( x) = 5 x 4 + 20 3 x 3 f ″ ( x) = 20 x 3 + 20 x 2 = 20 x 2 ( x + 1) Step 2: Finding all candidates. Similar to critical points, these are points where f ″ ( x) = 0 or where f ″ ( x) is undefined. f ″ is zero at x = 0 and x = − 1 ...

Now you make a test interval from: #(-oo,0)uu(0,3)uu(3,oo)# You test values from the left and right into the second derivative but not the exact values of #x#. If you get a negative number then it means that at that interval the function is concave down and if it's positive its concave up. If done so correctly you should get that:Are you dreaming of a luxurious vacation at a stunning resort?

The goal is to subtract the starting time from the ending time under the correct conditions. If the times are not already in 24-hour time, convert them to 24-hour time. AM hours are the same in both 12-hour and 24-hour time. For PM hours, add 12 to the number to convert it to 24-hour time. For example, 1:00 PM would be 13:00 in 24-hour time.Green = concave up, red = concave down, blue bar = inflection point. This graph determines the concavity and inflection points for any function equal to f(x). 1In Calculus, an inflection point is a point on the curve where the concavity of function changes its direction and curvature changes the sign.
