Answer:
16 days would be taken.
Step-by-step explanation:
Given that:
6 sheep = 8 cows
1 sheep = (8/6) cows
9 sheep = (8*9)/6 cows
9 sheep = 12 cows
9 sheep + 5 cows = 12 cows + 5 cows
= 17 cows
Now 8 cows can gaze field in 34 days
1 cow can gaze field in (34 * 8) days
17 cows can gaze field in (34*8)/17 days = 16 days
So 9 sheep and 5 cows will take 16 days to graze the field.

Answer:
68%
Step-by-step explanation:
The mean is 32 minutes, and the standard deviation is 4 minutes.
28 is 1 standard deviation below the mean, and 36 is 1 standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and 1 standard deviations. 95% is between -2 and 2 standard deviations. 99.5% is between -3 and 3 standard deviations.
So the answer is 68%.
