Answer:
28 quarters and 12 nickles
Step-by-step explanation:
How many quarters goes into 7 dollars? 28, because there is 4 in each dollar.
How many nickles are in 60 cents? 12, because 5 times 12 is 60.
Since as of now we're saying that the probability of having a girl is 1/2, we can say:
1/2 * 1/2 * 1/2 * 1/2, because then you're saying a one half chance of having a girl times another one half chance of having a girl, etc.
That ends up to be 1/16.
M = 135/19 and n = -5/19
You have to give them like terms so that when you eliminate they cancel out and you can solve. The easiest way to do so is by multiplying the top equation by -4 and the bottom by 3.
