Answer:
A function is said to be an even function if its graph is symmetric with respect to the y-axis. For example, the function f graphed below is an even function. Verify this for yourself by dragging the point on the x-axis from right to left. Notice that the graph remains unchanged after a reflection across the y-axis!

Answer:
the chance that the population mean will either be less than $1,500 or above $2,100 is 10%
Step-by-step explanation:
We are 90% confident that the true population mean willl be between $1,500 and $2,100
This means that there is a 90% probability that the true population mean will be between $1,500 and $2,100.
So 100-90 = 10% probability that it is outside of this interval, that is, either be less than $1,500 or above $2,100.
So the correct answer is:
the chance that the population mean will either be less than $1,500 or above $2,100 is 10%
Answer:
The sum of three consecutive integers for 198 are <em>65, 66, and 67</em>
Definition of "INTEGERS"
1. a whole number; a number that is not a fraction.
2. a thing complete in itself.
Step-by-step explanation:
198 = x + x + 1 + <em>x + 2</em>
combine like numbers
198 = 3x + 3
subtract 3 from like numbers (in this case)
198 - 3 = 3x + 3 - 3
195 = 3x
divide by 3
195/3 = 3x/3
65 = x
x + 1 = 65 + 1 ---66
x + 2 = 65 +2 --67
