Answer:
Gradient of line A = 0.8
Gradient of line B = 0.75
Therefore the lines are not parallel
Step-by-step explanation:
1. Rearrange the equation of line A into the form Y=mX + C in order to find the gradient of line A which m in the equation represents the gradient.
2. Use the gradient formula, (y2-y1)/(x2-x1) to find the gradient of line B
Since the both have different gradient. It means that they are not parallel
Answer:
D
Step-by-step explanation:
The mean or average is calculated by summing each element and then dividing by the number of elements.
We have: 35, 30, 45, 65, 44, and 21.
There are six elements in total.
We find the sum by adding. Hence:
We will now divide by 6, the number of elements:
Therefore, the mean runs scored by the batsman is 40.
Hence, our answer is D.
