Answer: b^3+ 64b^2 - b/16 -4
Step-by-step explanation:
Based on the first three (3) recordings, your average heart rate in beats per minute is approximately 84 bpm (mean). Calculating for the standard deviation of the samples, we get about 2.5 bpm. To give the possible heart rates on the fourth, we may solve for the range:
Upper Range = Mean + Standard Deviation = 84 + 2.5 = 86.5 bpm or 87 bpm
Lower Range = Mean - Standard Deviation = 84 - 2.5 = 81.5 bpm or 82 bpm
Therefore the fourth and final recording will likely to fall in the range of 82 - 87 beats per minute. You will win the fitness award!
<em>ANSWER: 82-87 beats per minute</em>
Answer:
13
Step-by-step explanation:
7 x 2=14
40-14=26
26/2=13
Step-by-step explanation:
subtract 7155 from both sides, multiply both sides by 10130, and then divide both sides by two
