Step-by-step explanation:
The parabola has a line of symmetry at x=0 so that means we can reflect the function across the y axis and it will remain unchanged so the answer is even function.
The number of possible outcomes is 8.
The probability of getting exactly one tail is 3/8.
The probability of getting at most two tails is 3/4.
<h3>What are the probabilities?</h3>
Here is the sample space if 3 coins are tossed: {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. There are 8 possible outcomes.
The probability of getting exactly one tail = number of times only one tail is gotten / total number of possible outcomes
3/8.
The probability of getting at most two tails = number of times at most two tails is gotten / total number of possible outcomes = 6/8 = 3/4

Answer:
All real numbers would be the solution
Step-by-step explanation:
2y - 4x =2 and y = 2x + 1
We solve but placing the value of y into the first equation:
2(2x + 1) - 4x = 2
Next we distribute the 2 through the parenthesis:
4x + 2 - 4x = 2
Now we gather like terms:
2 = 2 ( note the 4x and - 4x cancel out)
Since 2 =2 this tells us that all real numbers would work.
A modulus is pretty much just the square root of x^2 + y^2, where y is the number that stands with the imaginary “i” and x is the real number. In this case, x is 2 and y is 3, so your modulus would be the square root of 4 + 9 (2^2 + 3^2), or the square root of 13.
