Therefore, the hiker's hiked 
more in the morning than in the afternoon.
Answer:
The distance is 9.
Step-by-step explanation:
Just look, that these points have got the same x-coordinate,
so they lie on the same line, which is parallel to the OY axis,
So your taks is only find different in y-coordinate. That is
12-3 = 9
Answer:
3/7
Step-by-step explanation:
P(red) = number of red pens / total number of pens
= 3/7
Answer:
-12
Step-by-step explanation:
Since a = -6,we have to multiply 2 and -6,and you get -12 bc we have to put the sign of the bigger digit which is -6 in this problem,so you have to write -12
The number of non-blue marbles you need to combine with the blue marbles to achieve a probability of 0.1 is 28.
<h3>How many non-blue marbles are needed?</h3>
Probability determines the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
Probability of picking a blue marble = number of blue marble / total number of marbles
4 / (4 + 8)
4/12 = 0.33
The number of non-blue marbles needed = ( 4 / 0.1) - 12
40 - 12 = 28
