Answer:
Step-by-step explanation:
slope, m = 0.1m/4m = 0.025
Theoretical effort (ignoring friction) = 9000N * 0.025 = 225 N
actual effort = 300 N
efficiency
= potential energy out / actual energy in
= 225 N / 300 N = 0.75
Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
If p=4, plug in 4 to the equation.
1. q= 20 - 0.05 * 4^2
2. q= 20 - 0.05 * 16
3. q= 20 - 0.8
4. q= 19.2
