For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.

A box has a width of 10 cm and a length of 17 cm. The volume of the box is decreasing at a rate of 527 cubic cm per minute, with
Ber [7]

Answer:

-3.1 cm per minute.

Step-by-step explanation:

We have been given that a box has a width of 10 cm and a length of 17 cm. The volume of the box is decreasing at a rate of 527 cubic cm per minute, with the width and length being held constant.

We know that volume of a cuboid is length times width times height.

V=lwh

Upon substituting our given width and length, we will get:

V=17\cdot 10\cdot h

V=170\cdot h

Now, we will find derivative of volume with respect to time as:

\frac{dV}{dt}=170\cdot \frac{dh}{dt}

Since the volume of the box is decreasing at a rate of 527 cubic cm per minute, so we will substitute \frac{dV}{dt}=-527  as:

-527=170\cdot \frac{dh}{dt}

\frac{-527}{170}=\frac{170\cdot \frac{dh}{dt}}{170}

\frac{dh}{dt}=-3.1

Therefore, the rate of change in height is -3.1 cm per minute.
