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>
The answer should be D. 2x plus 3x is 5x. -6+9 is +3.
Answer: H (131.125 ft^2)
Step-by-step explanation:
first, you need to find the area of the wall
wall:
A=Lw (length times width)
A= 9.75 x 15.5 (I changed them into decimals)
A = 151.125
now you need to find the area of the window
window:
A = Lw
A = 4 x 5
A = 20
now you need to subtract the area of the window from the area of the wall to find the amount of space you need to cover with wallpaper
151.125 - 20 = 131.125
Caixa de Marcos = m
caixa de Drew = m-8
Drew levantou 14 caixas
Marcos levantou 9 caixas
D = 14(m-8)
