Answer: 0
Step-by-step explanation: In order to identify the <em>y-intercept</em> of this equation, we want to get this equation into slope-intercept form which is more commonly known as y = mx + b form.
The problem is our equation doesn't match up quite so well with the formula y = mx + b. Our slope or <em>m</em> which is represented by the coefficient of the <em>x</em> <em>term</em> is clearly +4 but what is our y-intercept or b?
Well y = 4x can be thought of as y = 4x + 0 so you can see that our b or y-intercept equals 0.

Answer:

Step-by-step explanation:
The probability that the man gets x out of 20 correct follows a Binomial distribution, so the probability is calculated as:

Where n is the number of identical experiments and p is the probability of success. In this case n is 20.
Additionally, if he has no ESP the probability that he predict correctly is 0.5, because he is only guessing.
Then, the probability that he gets x out of 20 correct is equal to:

Therefore the probability that he would have done at least 17 out of 20 well if he had no ESP is:

Where:

So,
is equal to:

Answer:
The number of nickels is 17 and number of dimes is 8.
Step-by-step explanation:
Let the number of nickels be x and number of dimes be y.
Total number of coins is 25.
.... (1)




.... (2)
On solving (1) and (2), we get




Put this value in equation 1.


Therefore the number of nickels is 17 and number of dimes is 8.
