Answer:
r = 8,9,10
Step-by-step explanation:
The given inequality is :
5r≤6r−8 ...(1)
We need to find the value of r.
Subtracting 5r to both sides of the inequality .
5r-5r≤6r-5r−8
0≤r−8
r ≥ 8
Hence, the values of r are 8,9,10.
Answer:
The Alan's average for course is 72.65.
Step-by-step explanation:
Given that,
Each test counts as 15% of the course grade. 20% of course grade is counted term test paper. Alan has test scores of 79, 95, 89, and 81. Alan got 81 score on his term paper . Alan's final examination score = 85.
Let n number x₁,x₂,......., with respect to assigned weight,,......., is
Where is the sum of the products the number with the relevant weight.
weighted mean
=72.65
The Alan's average for course is 72.65.

Answer:
Kite; x = 3
Step-by-step explanation:
The quadrilateral shown is a kite.
We can first prove the 2 triangles in the kite are congruent.
Since the 3 sides of the triangle all matches with the other triangle (as the no. of strokes on the lines indicate them having the same length), and the base is a common side of both triangles, they are congruent for SSS (side, side, side).
Congruent triangles have the same interior angles.
So, we can deduce that (9x + 6)°= 11x°
(9x + 6)°= 11x°
6° = 11x° - 9x°
6° = 2x°
x° = 6/2°
x = 3
Answer: <em>Option (A) is correct.</em>
Step-by-step explanation:
Let's assume the following result from the data analyzed:
Most motorcyclists who were involved in serious accidents, they did not take in consideration to take the course - this would suggest "Motorcyclists who did not take the course were more likely to get in a serious accident."
Therefore, if only 8% of motorcyclists have taken in consideration to take up this course, then this would predict that courses did not have a compelling effect on safety, thereby hindering the argument.
However, if compelling more than 8% of motorcyclists took this course, then the data would predict that courses were effective.
