Answer:
X=-Y
Step-by-step explanation:
...........................
Answer:
The solutions to the system of equations are:
Thus, option C is true because the point satisfies BOTH equations.
Step-by-step explanation:
Given the system of the equations
Arrange equation variables for elimination
solve for x
Divide both sides by -2
The solutions to the system of equations are:
Thus, option C is true because the point satisfies BOTH equations.
Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- p = probability of success = 0.4
- q = 1 - p = 0.6
- n = number of trials = 100
P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
<u>Using a binomial probability calculator</u> :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271
