Answer:
12m
Step-by-step explanation:
All you have to do in this problem is count 3m for every tree that passes. Since we are starting with the second tree, you can just count 3m for tree 2 to tree 3, then another 3m for tree 3 to 4, and so on until you get to tree 6. In total, your answer should be 12 m

Step-by-step explanation:
Answer:
Step-by-step explanation:
Let total shirts be x.
Then, Striped shirts = 1/9x
Remaining Shirts= 8/9x
Therefore, Printed Shirts = 5/8 × 8/9x
= 5/9x
Remaining Shirts
or
Plain Shirts= x - ( 5/9x + 1/9x )
= 3/9x
Acc. to problem,
Plain Shirts=81
Therefore,
3/9x=81
=> x=81×9/3
=> x=27×9=243
Therefore,
Total Shirts= 243

Answer:
And we can conclude that the true mean for the heights of mens between the ages of 18 to 24 is between 69.44 and 69.7 inches.
Step-by-step explanation:
For this case we have the following sample size n =772 from men recruits between the ages of 18 to 24
represent the sample mean for the heigth
represent the population standard deviation
We want to construct a confidence interval for the true mean and we can use the following formula:
The confidence level is 0.99 or 99%o then the significance level is 
and 
and if we find for a critical value in the normal tandar ddistirbution who accumulates 0.005 of the area on each tail we got:
And replacing we got:
And we can conclude that the true mean for the heights of mens between the ages of 18 to 24 is between 69.44 and 69.7 inches.
