In an effort to try to convince her mother that she is too old to join the intermediate swim class, Mira, who is 13 years old, gathers data on the ages of a random sample of members of the current
intermediate swim class. The results of the data collected by Mira are displayed in the dot plot shown.
Complete parts a and b.

a. The data are clustered between and years old.
(Type whole numbers. Use ascending order.)
b. Based upon the data collected, is it likely that Mira will be able to convince her mother that she is
too old to join the intermediate swim class? Explain.

It likely that she will be able to convince her mother. Mira's age is
where the data are clustered.

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
