Answer: y = 4x + 11
Step-by-step explanation:First, you put the equation into the standard “slope/intercept” form.
4x -y = 2 subtract 4x from both sides ; -y = -4x + 2 Multiply by -1 :
y = 4x - 2
In this standard form we see that the slope of the line (coefficient of x) is 4. ANY line parallel to this one must thus also have a slope of 4.
y = 4x - a (generic)
ANY other combination of slope multiples and constant terms will therefore also be lines parallel to this one. The one that passes through a specific point will simply have a different constant term.
We find this by putting our point value into the equation:
3 = 4(-2) + a ; 3 = -8 + a ; a = 11
Thus, our “parallel line equation” through the point (-2,3) is:
y = 4x + 11
Answer:
50% of students have a GPA higher than 3.1.
Step-by-step explanation:
We are given that the mean GPA of students in a neighboring school is 3.1 with a standard deviation of 0.3.
Assuming that the data follows normal distribution.
<u><em>Let X = GPA of students in a neighboring school</em></u>
So, X ~ Normal()
The z score probability distribution for normal distribution is given by;
Z = ~ N(0,1)
where, = population mean GPA = 3.1
= standard deviation = 0.3
Now, the probability that the students have a GPA higher than 3.1 is given by = P(X > 3.1)
P(X > 3.1) = P( > ) = P(Z > 0) = 0.50
<em>The above probability is calculated by looking at the value of x = 0 in the z table which has an area of 0.50.</em>
Therefore, 50% of students have a GPA higher than 3.1.
$0.40 for the first part but I'm not so sure about it, so I'm sorry if I'm wrong. And I'm not sure about the second part either. Sorry
