Answer:
(5, -1)
Step-by-step explanation:
Add the x-coordinates and divide by 2.
Add the y-coordinates and divide by 2.
x-coordinate of midpoint: (2 + 8)/2 = 10/2 = 5
y-coordinate of midpoint: (-5 + 3)/2 = -2/2 = -1
Midpoint: (5, -1)
Answer:
16= 7 &
17= 9
Step-by-step explanation:
A and B are dependent events.
The general probabilities of each event to happen separately is 36% for event A and 25% for event B. When considering that Chris passes one before passing the other, indicates that whether he gets the first light open or not will affect if he gets the other one also open or not. This can even be seen by noticing how the probability of Chris getting both red lights is 9%, a much inferior probability then considering both lights separately which means that one event has influence over the other.
Answer:
The answer to the question is 10a√2a(b + 2)
Step-by-step explanation:
To know the student's error, let us calculate the perimeter from the the start.
Dimension of the rectangle is given below:
√(50a³b²) and √(200a³)
Perimeter of a rectangle = 2(L + B) = 2L + 2B
2√(50a³b²) + 2√(200a³)
2 x 5ab√2a + 2 x 10a√2a
10ab√2a + 20a√2a
Factorise
10a√2a (b + 2)
Therefore, the student made an error by adding 10ab√2a and 20a√2a together.
Note: we can not add 10ab√2a and 20a√2a together since b is missing in one of the expression.
Therefore, the answer to the question is 10a√2a(b + 2).
