Answer:
The probability is 3/95
Step-by-step explanation:
Okay this is a probability without replacement question.
Firstly we calculate the total number of coins = 7 + 9 + 4 = 20 coins
The probability that the first coin will be a dimes = number of dimes/total number of coins = 4/20 = 1/5
Now she removes a coin without replacement, if it was a dime, total number of coins becomes 19 and the total number of dimes becomes 3; Thus the probability of the second coins being a dimes = 3/19
Thus, the probability of both coins being dimes = probability of first coin being dimes * probability of second coins being dimes
= 1/5 * 3/19 = 3/95
Answer:
The solutions are and .
Step-by-step explanation:
We have the following equation:
.
The first step to solve this problem is using
We replace in the equation 1, find the values of y, and then we replace in equation 2) to find the values of x.
To solve the equations, it is important to know how we find the roots of a second order polynomial.
Given a second order polynomial expressed by the following equation:
This polynomial has roots such that , given by the following formulas:
In this problem, we have
So
So:
The values of y are
We also have that:
So
And
There is no real solution for this. So our only solutions are and .
