Answer: Yes they are right triangles
Explanation:
The square grid markers help us line up the angles to see that angle OBC is a 90 degree angle, and so is angle OB'C'. Any time a vertical and horizontal line meet up is when you have a 90 degree angle. A right triangle is one where it has a 90 degree angle (aka a right angle).
Extra info: it can be shown that triangle OBC is similar to triangle OB'C', which leads to the fact that the triangles are proportional.
Answer:
Yes they are independent events
Step-by-step explanation:
In order to solve this, you need to first know the definition of probability of independent event.
two events are independent if the incidence of one event does not affect the probability of the other event. When that occurs, the expression or formula to calculate is the following:
P(A∩B) = P(A) * P(B)
So, in order to see if A and B are independent, let's see how the calculations do with the data provided
P(A∩B) = P(A) * P(B) = 1/4 * 2/5 = 2/20 = 1/10
Therefore, A and B are independent events
Answer:
They can make 4 teams.
Step-by-step explanation:
You can see that 24 cannot be divided by 5, but you can subtract 4 from 24 to get 20, which is a multiple of 5. 20 divided by 5 is 4, so they can make 4 teams.
Answer:
Step-by-step explanation:
for x then 4 = (x1+7)/2
8 = x1 + 7
1 = x1
for y then -3 = (y1+0)/2
-6 = y1
C = ( 1,-6 )
