To calculate averages you must first add all the test scores.

add 82, 90, 78, 76 and 94.

next choose one of the options and add it on to the sum that you got from the original test scores

now divide the whole thing by how many trials there were (how many tests were done). in this case, including the option, 6 trials were completed so divide by 6.

if the answer is not 86, then repeat for other options until you get 86

<h2>At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.</h2>

Step-by-step explanation:

We have equation for volume of a sphere

             V=\frac{4}{3}\pi r^3

where r is the radius

Differentiating with respect to time,

            \frac{dV}{dt}=\frac{d}{dt}\left (\frac{4}{3}\pi r^3 \right )\\\\\frac{dV}{dt}=\frac{4}{3}\pi \times 3r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}

Given that

           Radius, r = 24 cm

           \frac{dr}{dt}=0.3cm/s

Substituting

           \frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi \times 24^2\times 0.3\\\\\frac{dV}{dt}=2171.47cm^3/min

At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.

Answer:

D) a 360° clockwise rotation about the center of the parallelogram will take the parallelogram <em>PQRS </em> onto itself.

Step-by-step explanation:

The parallelogram <em>PQRS </em>is in quadrant III (3) of the coordinate plane.  If the image is reflected over the line x = -5 or y = -5, it would be the mirror image of itself and would move either left (x = -5) or down (y = -5) over the lines.  A 180°  rotation about the center of the parallelogram would move the object to quadrant I (1).  However, a 360° clockwise rotation about the center of the parallelogram would cause the object to make a full circle and take the  parallelogram <em>PQRS </em> onto itself.
