Given tip, T = $2.00 + (0.1 X C)
where C = cost of meal
Mean of cost of meals, M = $9.00
Standard deviation of meal, Sm = $3.00
If C = M,
Mean of tips Mt = $2.00 + (0.1 X $9.00)
Mt = $2.90, mean of tips
Standard deviation of tips, St = square root of mean of tips
St = ($2.90)^0.5
St = $1.70, standard deviation of tips
Therefore, mean of tips = $2.90 and standard deviation of tips = $1.70
<span>We can calculate the speed of sound with this formula:
v = 331 + 0.6T, where v is the velocity of the sound wave in units of m/s and T is the temperature measured in degrees Celsius.
When the temperature is 36°C, the velocity of the sound wave is:
v = 331 + (0.6)(36) = 331 + 21.6 = 352.6 m/s.
The correct answer is A. 352.6 m/s
(Please note that we do not use the unit Hz to measure the velocity of a sound wave. The unit Hz is used to measure frequency. We should use m/s to measure the velocity of a sound wave.)</span>

All single-celled organisms contain everything they need to survive within their one cell. These cells are able to get energy from complex molecules, to move, and to sense their environment. The ability to perform these and other functions is part of their organization.
