You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.
In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.

2. Sorry, I don't how to put that into words, because i'm trying to use calculators, then figure out how they got their answer.

3. to get the difference between two numbers, (100 and 50, for example,) you must just simply have them minus each other, like simple math. 100 - 50 = 50.
So your difference between the number 100, and the number 50, are 50.
Answer:
The standard error of the mean is 0.0783.
Step-by-step explanation:
The Central Limit Theorem helps us find the standard error of the mean:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
The standard deviation of the sample is the same as the standard error of the mean. So
In this problem, we have that:
So
The standard error of the mean is 0.0783.
She bought 4, then she bought 3 more....so she bought 7 packs
each pack contains 12 pencils..
so 7 packs each containing 12 pencils ...
7(12) = 84 total pencils <===
Answer:
y = 3x + 1
Step-by-step explanation:
Since we know the Graph is Parallel to y = 3x + 11, we know that the "mx" portion of the equation is 3x since only the "b" would be different.
Then we just substitute in the point and to find b.
4 = 3(1) + b
b = 1
y = 3x + 1 is the answer
