Answer:

The value of x is 7 and y is 14.

Step-by-step explanation:

The steps are :

$- 3x + y = - 7 - - - (1)$

$y = x + 7 - - - (2)$

$(2)→(1)$

$- 3x + (x + 7) = - 7 \\ - 3x + x + 7 = - 7 \\ - 2x = - 14 \\ x = 7$

$substitute \: x = 7 \: \: into \: \: (2)$

$y = 7 + 7 \\ y = 14$

A biased coin has a probability of 0.4 of coming up heads. What is the probability that when flipped one hundred times it comes

inn [45]

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
