Answer:
c = -5
Step-by-step explanation:
Plug in -5 to c in the equation:
c² - 25 = 0
(-5)² - 25 = 0
Simplify. First, solve the power, then solve the subtraction:
(-5)² - 25 = 0
(-5 * -5) - 25 = 0
(25) - 25 = 0
0 = 0 (True)

Answer:
The probability is 0.4909
Step-by-step explanation:
The following equation for nCk give as the number of ways in which we can select k elements from a group of n elements:

Then, there are 220 ways in which we can select 3 candies from the 12 that are in the pack. It is calculated as:

On the other hand, there are 108 different ways to select the 3 candies in which they are all different flavors. It is calculated as:
4C3 * 3C1 * 3C1 * 3C1 = 108
Because, 4C3 give us the number of ways to select 3 flavors from the 4 flavors. From this 3 flavors selected, we are going to select one candie from each one, so we multiply 3 times by 3C1, one for each flavor.
Finally, the probability is the division between the number of ways in which we can select 3 candies with different flavors and the total number of ways in which we can select 3 candies from the 12 in the pack. This is:

Answer:
Total number of notes is 11.
Step-by-step explanation:
Value is 100 rupees…
5x + 20y = 100 and x + y = 11 are the two equations.
We can simplify…
5x + 20 y - 5x - 5y = 100 - 55 = 45
15y = 45 so y = 3
x = 11 - y = 8
So, we have 8 notes of 5 rupees denomination and 3 notes of 20 rupees denomination.
