Answer:
Result is statistically significant.
Step-by-step explanation:
Given that :
Chisquare statistic, χ² = 67.81
Critical value for the distribution, χ²critical = 3.84
α = 0.05
The Decison region :
If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.
Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
Equation of a line passing through point (x1, y1) with slope m is given by y - y1 = m(x - x1)
For parallel lines, the slope of the required line is equal to the slope of the given line.
x = -3 is a vertical line, therefore, the required line will also be a vertical line since they are parallel.
Since the required line passes through point (4, 2), the equation of the required line is x = 4.
The question requires that the four lines that intersect form a parallelogram but not an specific parallelogram, so you are not restricted by a diagram.
You can use these equations for the four lines:
1) y = 0 (it is the x-axis)
2) y = 4 (it is a line parallel to the x-axis, whose y-intercept is 4.
3) y = x (it is an inclined line that intersects both y = 0 and y = 4 lines.
4) y = x + 7 (it is a line parallel to y = x, that also intersect the both y = 0 and y = 4 lines.
Answer:
7m
Step-by-step explanation:
Let m be the miles he jogs each day
No. of days in a week = 7
He jogs in 1 day = m miles
He jogs in 7 days = m times 7 = 7m
