Answer:
y=6x
Step-by-step explanation:
Frist, you are going to use y=mx+b
M= the slope of the line.
B= the y-intercept( where the line crosses the y-axis).
Slope= the you simplify it to
= 6
Now, you plug in your equation for m.
y=6x+b
Y-Intercept= where the line crosses the y-axis.
In this case it is at 0. Now plug it in.
y=6x+0
Whenever your "b" is 0 you don't need to add +0 in your equation.

The Z-score is 2.306 to three decimal places. However, the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis
A z-score is a measurement of how often standard deviations the score obtained from a z-test is beyond or under the mean population.
From the given data information, let us find the mean and the standard deviation.
Mean (x) = 2425.6
The hypothesis testing can be computed as:
The standard deviation (σ) is:
= 1788.71
Now, the Z-test statistic is determined using the formula:
Z ≅ 2.306
Therefore, at a 0.05 level of significance, the Z-critical value is 2.306. However, since the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis
The complete question is given as:
Using a sequencing method called "RNAseq," a researcher determines the level of FOXP2 expression in 10 different samples of lung tissue, and obtains these data:
- 1154 5998 1007 2501 1000 988 2547 3987 4187 887
Scientist has previously determined that FOXP2 is expressed in brain tissue at a level of 6,550. Calculate the Z-score associated with a test to see if the average expression of FOXP in her lung tissue samples is different from the levels she measured from brain tissue.

Parallel lines have the same slope
The equation of the line is:
The equation is given as:
The slope intercept form of an equation is:
Where:
By comparison,
The line is said to be parallel to .
This means that the line has a slope of
The equation of the line is then calculated as:
Where:
So, we have:
Substitute values for m, x1 and y1
Open brackets
Hence, the equation of the line is:
