37.50 -25.00= 12.50 so Luisa makes 12.50 more a month than Maria. Divide 100/12.5 = 8. It will take Maria 8 months to be exactly $100 ahead of Luisa.
Answer:
The best estimate of the probability of getting a green marble from this bag of 50 marbles is 1/3.
Step-by-step explanation:
Andre gets 1 green marble out of 4 trials.
For Andre, the probability of getting 1 green marble is 1/4.
Jada gets 5 green marbles out of 12 trials.
For Jada, the probability of getting 1 green marble is 5/12.
Noah gets 3 green marbles out of 9 trials.
For Noah, the probability of getting 1 green marble is 3/9.
Hence, the best estimate of the probability of getting a green marble from this bag = (1/4 + 5/12 + 3/9)/3 = [(9 + 15 + 12)/36]/3 = 1/3.
It is C) 2.55 because i was taught that you can subtract the negative from the positive. 5.35-2.8=2.55 and it is positive
(-3) - (-3) = - 6
3 + (-3) = 0
