Your answer is 40. 25% is equal to 1/4. So 10*4=40. 40*.25=10.
Okay. I think to find the number of green and blue marbles each, we have to find the LCM of 8 and 7. The LCM of 8 and 7 is 56. There are 56 green marbles and 56 blue marbles. That a total of 112 marbles combined. 140 - 112 = 28. There are 28 red and yellow marbles. There are an equal number of both. 28/2= 14. There are 14 red marbles in the bag.
Yes, the situation as described is proportional.
Discussion:
According to the question:
- We are required to determine if the situation described in the question is proportional.
Since, Aisha pays $2 for each game she plays at the arcade.
In essence, the total amount of money paid by Aisha will depend on the number of games she plays. On this note, the situation is proportional.

Answer:
The sample size is 4
Step-by-step explanation:
Null hypothesis: The mean is 2
Alternate hypothesis: The mean is less than 2
Mean = 3
sd = sqrt(variance) = sqrt(4) = 2
At 95% confidence level, t-value is 1.960
Assuming the lower bound of the mean is 1.04
Lower bound = mean - (t×sd/√n)
1.04 = 3 - (1.96×2/√n)
3.92/√n = 3 - 1.04
3.92/√n = 1.96
√n = 3.92/1.96
√n = 2
n = 2^2
n = 4
I think your answer would be -4
