Step-by-step explanation:
81924
+ 3827
_______
85751
- Start from the right side, 4 + 7 = 11, but the 1 is carried over
- 2 + 2 + 1 = 5
- 9 + 8 = 17, but the 1 is carried over
- 1 + 3 + 1 = 5
- 8 + 0 = 8
Thus, the answer becomes 85751.
The answer to the question
Answer:
78.88%
Step-by-step explanation:
We have been given that

The z-score formula is given by

For 

For 

Now, we find the corresponding probability from the standard z score table.
For the z score -1.25, we have the probability 0.1056
For the z score 1.25, we have the probability 0.8944
Therefore, the percent of the trees that are between 20 and 30 years old is given by
0.8944 - 0.1056
= 0.7888
=78.88%
