Try it.
8 =? 2*8 - 4
8 =? 16 - 4
8 =? 12
8 is not a solution of the original equation
Try 4
4 = 2*4 - 4
4 = 8 - 4
4 = 4 and yes 4 works.
4 is unique. No other solution will work.
Answer:
<h2>
The slope is <u>
3</u></h2><h2>
To graph it you should put a point at any of the points that are in the table. Some easy ones are (0,0) and (2,6)</h2>
Step-by-step explanation:
To find the slope you need to follow the formula shown below.
Slope (m) = ΔY/ΔX
Now solve
ΔY = 6 – 0 = 6
ΔX = 2 – 0 = 2
Write as a fraction
6/2
Convert to a number
6/2 = 3
And you have your slope. Now you just have to plot the points on the graph. As I said before, you can use any two points from the table.
Answer:
Null hypothesis
Alternative hypothesis
The p value is 0.000517, which is less than the significance level 0.01, therefore we reject the null hypothesis and conclude that population mean is not equal to 5.00.
Step-by-step explanation:
It is given that a data set lists earthquake depths. The summary statistics are
Level of significance = 0.01
We need to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 5.00.
Null hypothesis
Alternative hypothesis
The formula for z-value is
The p-value for z=3.4719 is 0.000517.
Since the p value is 0.000517, which is less than the significance level 0.01, therefore we reject the null hypothesis and conclude that population mean is not equal to 5.00.
The answer will me C...................
We can drop a perpendicular from X to PQ at A, and from Y to RS at B. Then XA = YB = 48/10 = 24/5. We can also draw a line through X parallel to BY meeting the line through Y parallel to RS at C.
Then XC = 24/5 + 24/5 + 10 = 98/5 and YC = 10 - 34/5 = 16/5, so XY^2 = XC^2 + YC^2 = (98/5)^2 + (16/5)^2 = 1972/5.
