Suppose y varies inversely with x, and y = 32 when x = 4. What is the value of y when x = 8?

Mathematics
1 answer:
bulgar [2K]3 years ago
6 0

Answer:

16

Step-by-step explanation:

Inverse variation is of the form

xy = k where k is a constant

x=4 and y = 32

4*32 = k

128 = k

xy = 128

Let x = 8

8y = 128

Divide each side by 8

8y/8 = 128/8

y =16

Consider the function f(x) = x^{2/3} on the interval [-1,8].
zhannawk [14.2K]
The right option is (c). The Mean Value Theorem does not apply since f(x) is not differentiable on (-1,8). Because the derivative of f is 2/3 x^(-1/3)  which is undefined at x=0.So, that would imply that it is not differentiable along the interval.

The following set of data represents letter grades on term papers in a rhetoric class: A,A,A,B,B,B,B,C,C,C,C,C,C,C,C,C,D,D,D,F.
Viktor [21]

Answer:

c. Mode

Step-by-step explanation:

Mean is the average obtained by adding all values and then dividing by the size of the values. Here, adding A and B etc is not clear.

Median is the middle value of a set of numeric values. To find a median, values should be sort-able from smallest to the largest. If there is no unique middle value, then the average of the middle values has to be taken. Here, average of the two different grades is not clear.

Mode is the value that occurs most often. Clearly C occurs most often.

Mid-range value is the mean of the difference between largest value and the smallest value. Here, difference between A and F is not clear.

Mean,median,Mid-range are applied to numeric values where mode is also suitable for categorical values.

Therefore, the most appropriate measure of central tendency for the data described is mode
