Step-by-step explanation:
From the question we are told that:
Sample mean 1 
Sample mean 1 
Sample standard deviation 1 
Sample standard deviation 1 
Generally the equation for Point estimate is mathematically given by
6 hikers = 4.5 lbs of trail mix
4.5 divided by 6= .75 lbs each hiker.
Answer:
11th revision
Step-by-step explanation:
The first revision is in 2018, and for each 3 years there is a new revision.
From 2018 to 2048, there are 30 years.
So to find how many revisions there are, we can divide the 30 years by the period of 3 years:
Number of revisions = total period / period per revision = 30 / 3 = 10 revisions.
As the year 2018 also has a revision, we have 10 + 1 = 11 total revisions.
So in 2048 there will be the 11th revision.
Let x be the number of song points.
Let y be the number of videos points.
We have the first expression:
5x + 7y = 295
We have the second expression:
10x + 3y=150
Solve for y and x:
x = (295 -7y)/5
10 ((295-7y)/5) + 3y = 150
590 - 14y + 3y =150
590 - 150 = 14y -3y
y=40 points
solving for x:
x = (295-7*40)/5
x=3 points/song
If she buy, all songs for 333 points
number of songs = 333 / 3
number of songs = 111
The answer is 111.
