Step-by-step explanation:
there should 90 value
the value of triangle is 90
First notice that f(x) is negative, so entire graph will be below x-axis.
Next find domain by setting what is inside sqrt greater than 0.
You can't take sqrt of neg number.
Finally plot some points, start at x = 1, y=0.
Then try x = 0, y = -1.
x = -3, y = -2.
Connect the points, done.
Jack should remove the maximum and minimum weight potatoes from the average weight of the potatoes to compensate for the extremes. Therefore, we are left with a data set of:
8, 9, 11, 7, 7, 8, 9, 7; so n = 8
The sum of these is 66
The average weight of each potato is:
66/8
= 8 ounces
Using sampling concepts, it is found that the correct option is:
b. The 9000 registered voters from California in the database.
Example of sampling, involving sample and population:
I survey 1000 randomly selected residents of New York State, asking if they are Buffalo Bills fans or not.
- The <em>sample </em>is the 1000 residents surveyed.
- The <em>population </em>is all New York State residents, as it is the pool with all available options to be sampled.
In this problem, 1000 registered voters in California are randomly selected from the database and asked their opinion, hence:
- The 1000 voters are the sample.
- The pool with all available options to be sampled is the <u>9000 registered voters in California from the database</u>, hence, it is the population, and option b is correct.
