Answer:
She must swim 10 feet before she reaches the surface; from <em>level -10</em> to<em> level 0 (Equation: </em>)
Step-by-step explanation:
Based on the information provided, you can assume that the surface of the lake is at <em>level 0.</em>
You know that the swimmer dives 10 feet below the surface; this is the <em>level -10 .</em>
This means that she must swim 10 feet from the <em>level -10</em> to the level 0 in order to reach the surface of the lake.
Therefore, to find how far she must swim before she reaches the surface, it is necessary to add<em> levels -10 </em>and <em>+10</em> to get the<em> level 0.</em> This can be represented with the following equation:
Answer:
Probability that he or she has no desire in skiing lessons is 57/80
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
