Assuming that these two months each have 30 days then you have 60 days total and you divide that by 360 which means 2 months is 0.16666667 years
Answer:
210.8 (mean for Luis), 241.5 (mean for Darcy)
Step-by-step explanation:
Luis 178 + 213 + 198 + 245 + 236 + 198 + 221 + 253 + 189 + 177 = 2108
2108/10 = 210.8 (mean for Luis)
Darcy 231 + 210 + 245 + 259 + 286 + 245 + 231 + 244 + 236 + 228 = 2415
2415/10 = 241.5 (mean for Darcy)
C all angle measures under 90 degrees
The answer is B.
If you find a common denominator, the process becomes much easier. I hope this was helpful.
