Est: 1900/40=47.5
1908/36=53
Since the standard deviation is 10 and the first given score is 40, the 40 is 2 standard deviations below the mean.
On the other hand, 80 is 2 standard deviations above the mean.
Thus, we subtract the probability below the z-score which is 2, 0.97725, and the probability below the z-score which is -2, 0.02275.
We may obtain the values using the z-score table.
Therefore, the approximate value of the probability is 0.955.

If you have a minus power in the denominator, the base and power go to the numerator. The number in front does not change where it is.

When the minus power is in the numerator, the power and the base go into the denominator.

Answer:
750 monkeys (probable chance)
Step-by-step explanation:
100 : 50
100 square miles to a 2:1 ratio of 50 monkeys
Simply, insert the new area into the ratio to get the result.
1500 ---> 2:1
1500/2 = 750
1500:750
Thus, there would probably be 750 monkeys inhabiting a 1,500 square mile jungle.
let the number of sides be n.
Thus,
(n-2)x180=330
n-2=1.83
n=3.83
Rounding off we have, n=4.
Thus the total number of side is 4.
