1. A poll asked 15 men in two age groups, 40 and younger and older than 40, whether they watched the Super Bowl or not The results are recorded in the table.
Person Age group Watched the Super Bowl
1 40 and younger Yes
2 40 and younger No
3 Older than 40 No
4 40 and younger No
5 Older than 40 No
6 Older than 40 Yes
7 Older than 40 Yes
8 Older than 40 No
9 40 and younger Yes
10 40 and younger Yes
11 Older than 40 Yes
12 40 and younger Yes
13 Older than 40 Yes
14 40 and younger No
15 Older than 40 Yes
(a) Create a two-way table of the data. Of the men surveyed, how many were older than 40? How many men did watch the Super Bowl?
(b) 8 men 9 men

(c) Create a two-way relative frequency table that displays the relative frequency of men who did watch and men who didn’t watch that are 40 and younger and of the men older than 40. (hint -use watched

What is the area of the shaded sector?

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?
