Answer:
x + 5y - 25 = 0
Step-by-step explanation:
Equation of line in slope intercept form is given as:
The equation of <em>line m</em>, in point-slope form is: y + 3 = 4(x - 1)
<em><u>Recall:</u></em>
- The slopes of parallel lines are equal to each other.
- Slope-intercept form equation is: y = mx + b, where m is slope and b is y-intercept.
- Point-slope form equation is:
where,
is a point and m is the slope.
Equation of line m is y = 4x + 2
Slope of line m is 4
Since line m and line n are parallel, both lines will have the same slope. Therefore, the slope of line n is 4.
To write the equation for line if it contains the point (1, -3), substitute = (1, -3) and m = 4 into
:
Therefore, the equation of <em>line n</em>, in point-slope form is: y + 3 = 4(x - 1)

Answer:
Step-by-step explanation:
This is a question on hypothesis testing.
Population mean based on 30 year average for July was 90 with
a std deviation of 2.1
Sample of 5 shows average 93.5
To check whether sample average = population average
H0: x bar =90
Ha: x bar not equal 90(Two tailed test)
Test statistic =
=3.73
Since this lies outside the range (-1.96, 1.96) we reject null hypothesis
Hence we cannot say sample mean equals 90
