Answer:
1: It places them in an order sequentially relative to each other.
2: Number lines show the location of a number relative to each other on a one dimensional plane, and a coordinate plane does the same on two axis, or a two dimensional plane.
3: The order of the numbers do matter because the first one is the x coordinate and the second is the y. We nee a point of reference so we aren't able to make it so a single point can be represented by multiple ordered pairs, and vice versa so we can accurately share the information without additional interpretation.
4: (4.75, 2.25) Because to move across the x axis is to move in a direction perpendicular to it, meaning only the y coordinate will change. To be mirrored, it has to be copied and the absolute value of y (from both the x and y axis) must be maintained, just moved into the quadrant above or below it.
5: It is 7 units because the original coordinate would be 3.5 (as explained previously), and to move all the way to -3.5 you would need to cover the first 3.5 units to get to y=0, and then another 3.5 units down to get to y=-3.5. This is a total of 7 units moved.

Answer:
Mean hourly wages in at least 2 metropolitan areas are different
Step-by-step explanation:
0.05 level indicates a 5% risk of concluding that a difference exists even though there is no actual difference.
A test statistic is a refers to a quantity derived from the sample and it is used in statistical hypothesis testing.
A statistical hypothesis refers to a hypothesis that can be tested on the basis of observing a process that has been modelled as compared to a set of random variables.
It is a method of statistical inference.
In the given question,the test statistic was computed to be 4.91 at the o.05 level as seven employees were included from Area A, nine from Area B, and twelve from Area C when a preliminary study of hourly wages paid to unskilled employees in three metropolitan areas was conducted.
This implies mean hourly wages in at least 2 metropolitan areas are different.
Answer:
29 or D
Step-by-step explanation:
You square both sides to get
7 + y = 36
You then subtract 7 from both sides to get
y = 36 - 7
y = 29
The equation will be (3x)divided by 2
