Answer:
Ryan is correct.
Step-by-step explanation:
Laura says that the distance between (4, -2) and (4, -7) in the coordinate plane is equal to 1-2-(-7) units.
Here, x-coordinates are same, so the distance between these points is the difference between y-coordinates.
Distance between (4, -2) and (4, -7) = -2-(-7)
= -2+7
= 5 units.
So, Laura is incorrect.
Ryan says that the distance between the points (2, 3) and (-9,3) in the coordinate plane is equal to 2 + 9 units.
Here, y-coordinates are same, so the distance between these points is the difference between x-coordinates.
Distance between (2, 3) and (-9,3) = 2-(-9)
= 2+9
= 11 units.
Therefore, Ryan is correct.
Answer:
It is not ''significant''
Step-by-step explanation:
Let's call the event
A : ''Answer a question correctly if a random guess is made''
Now we calculate the probability for the event A
In the exercise A occurs in only one way and the total cases are the number of possible answers
An event B is ''significant'' if
⇒A it is not a ''significant'' event
