Answer:
C) (-4, 2)
Step-by-step explanation:
It is easier to begin by putting the y equation back into the x equation so it would be rewritten as:
x= 2 (-2x - 6) - 8
Since you replace the y for the given y value
Distribute and you get
x = -4x -12 -8
Add 4x to both sides to get rid of it on the right and balance the equation
5x = -12-8 which is -20
5x = -20
divide by 5 gives you the value -4 for the x
Now simply put that value in for the y equation
y= (-2 (-4)) -6
y = 8 - 6
y = 2
Answer:
62
Step-by-step explanation:
Answer:
AB = 32 ft
Step-by-step explanation:
If you rotate Triangle ECD 180 degrees clockwise, you will see that the sides line up perfectly with Triangle BCA, meaning that ED = AB and ED = 32 (transitive property of equality) so AB must also equal 32.
Answer:
7^4
Step-by-step explanation:
7^12 / 7^8
We know that a^b / a^c = a^(b-c)
7^(12-8)
7^4
The given case of Gallup asking the same 50 people how many hours had they worked at a job in the past 7 days. is an example of dependent sample.
<h3>What is dependent sample?</h3>
The measured values in relation in a dependent sample (also called a paired sample).
Some characteristics of dependent sample are-
- It is a dependent sample, for instance, if a sample of patients who have knee reconstruction is selected, and each patient is questioned during the procedure. The reason for this is that the identical person was questioned twice.
- If, for instance, you wish to examine if a new category of baseball bat really does have an impact on notable features and the same individuals play once from the old bat and once with new bat, you also have a dependent sample.
- Since each player utilized both bats, there are two measured values for each player, all measured values are likewise accessible in pairs.
- A variation is preselected based on the format wherein you insert your data. A series is typically a respondent and, more broadly, a case. Metric values in a sequence are therefore originally regarded as dependent.
