Step-by-step explanation:
A. the distance traveled on a trip and the travel time YES
B. the distance remaining on a trip and the travel time NO
C. the amount of money spent and the the number of shirts bought YES
D. the height of an eighth-grade student and the time to complete a puzzle NO
E. the amount of money owed on a computer and the time making payments NO (the amount of money owed drops with each payment made)
Answer:
D. 
Step-by-step explanation:
Since we know that the odds of an events can be found by dividing the probability that an event will occur by the probability that the event will not occur.
Probability of an event not occurring can be found by subtracting probability of the event occurring from 1.
We have been given that probability of an event is 2/7.
Upon substituting our given values in above formula we will get,
Therefore, the odds of the same event are and option D is the correct choice.
Answer:
B & C
Step-by-step explanation:
I'm not sure if you can have two answers but both of them are linear. A And D aren't because they have absolute value
Answer:
15 girls, 10 boys
Step-by-step explanation:
Since the ratio is 3:2, then the ratio can be rewritten as 15:10. So there are 15 girls and 10 boys
Answer:
3/2
Step-by-step explanation:
A couple of different methods are used for dividing fractions.
1. "Invert and multiply". Dividing by a number is the same as multiplying by its reciprocal:
(3/4) / (1/2) = (3/4) × (2/1)
= (3·2)/(4·1) = 6/4 = 3/2
__
2. Make the denominators the same and use the ratio of numerators.
(3/4) / (1/2) = (3/4) / (2/4) = 3/2
_____
For these fractions, you can recognize that 3/4 is 1/4 more than 1/2, and that 1/4 is half of 1/2. That means 3/4 is half-again as much as 1/2, so is 1 1/2 = 3/2 times 1/2. This tells you the ratio (3/4) : (1/2) = 3/2.
__
Along the lines of the above, you can write the ratio as ...
(3/4) : (1/2)
and multiply by 4 to get
= (3/4)×4 : (1/2)×4 = 3 : 2
