Answer:
It would take him approximately 16.62 minutes to reach the bookstore
Step-by-step explanation:
Total steps to the bookstore=Number of steps per minute×number of minutes
where;
Total steps to the bookstore=864 steps
Number of steps per minute=52

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%
(4ab - 9a - 8) - (7ab - 1)
distribute (multiply) the negative through the parenthesis
<span>(4ab - 9a - 8) - 7ab + 1
No need for other parenthesis because nothing in front or to combine inside. </span>
<span>4ab - 9a - 8 - 7ab + 1
</span>
Combine like terms
- 3ab - 9a - 7
