Say he has 2 dimes (D), 2 nickels (N), and 2 quarters (Q). There are 3 * 3 = 9 choices for what he can pull out. How many will give at least 30 cents?
Q and N, N and Q, Q and D, D and Q
That's 4 out of 9. So, the probability is 4/9.
Answer:
P(x) = 
Step-by-step explanation:
Root multiplicity of 2 means the root is repeated 2 times. Root multiplicity of 1 means root is repeated only once.
A polynomial of degree 3 means the largest exponent of x is 3.
Here, the polynomial P(x) has root 5 with multiplicity 2 and -5 with multiplicity 1.
So, P(x) = 
Where, 
is a constant.
Now, it's given that the y intercept is -87.5. Therefore, value of x at y intercept is 0.
We obtain by plugging in -87.5 for P(x) and 0 for x.
Therefore, the polynomial P(x) is given as:

Answer:
<u><em>The original price would be 50$.</em></u>
Step-by-step explanation:
To find this answer you have to divide 25% by 100, which equals 0.25. Now multiply 0.25 by 40 and you get 10$. Since 10$ was the discount, you just add 10$ + 40$, therefore 50$ is the original price.
