Step-by-step explanation:
1. The information in the question
explains that the groups are listed
alphabetically and that four groups
remain (A,B,C,D).
2. You can look at all four groups as
being equal to 100% and each individual
group as 25% of the total 100%. (The
same concept as four quarters being
equal to one dollar).
3. Because there are four groups left to
present and any of the four can be
selected at random this means that the
answer is option D. Group A, Group B,
Group C, Group D.

Water boils at different temperatures at different elevations. The boiling temperature of water is 212 degrees * F sea level (0
Nikolay [14]

Answer:

The elevation when the boiling point of water is 190 °F is 12790.70 feet

Step-by-step explanation:

Let every 1,000 feet of elevation be x. Hence, we can write

T = 212 - 1.72x

Where T is the boiling temperature of water at different elevations

Now, to the determine the elevation when the boiling point of water is 190 °F.

We will determine x by putting T = 190 °F.

Hence,

T = 212 - 1.72x

190  = 212  -  1.72x

190 - 212    = - 1.72x

- 22  = - 1.72x

22 = 1.72x\\x = \frac{22}{1.72} \\x = 12.79070

Since x represents every 1,000 feet of elevation, then the elevation when the boiling point of water is 190 °F

12.79070 × 1000\\ = 12790.70 feet

Hence,  the elevation when the boiling point of water is 190 °F is 12790.70 feet
