We will use binomial
distribution in this problem.
<span>The solution would be like
this for this specific problem:
</span><span>P(default) = p = 4% = 0.04 </span><span>
<span>q = 1-p = 1-0.04 = 0.96 </span>
n = 5</span>
<span>P(r) = nCr*q^(n-r)*p^r </span>
<span>Required probability =
P(r=2) = 5C2*0.96^3*0.04^2 </span>
= 0.0142 OR 1.42%
<span>The probability that at most
two customers in the sample will default on their payments is 1.42%.</span>
37.5*0.010=.375 (or press % button on calculator)
80*.375=30
Answer: y= -2 (x+1)
Step-by-step explanation:
this would be the “inverse” of the original equation making them cross at exactly 1 point
It would basically be 15-9 and not a negative so those two lines turn it into the opposite
<h2>
x = - 6 or, 1</h2>
Step-by-step explanation:
The given quadratic equation:
By factorisation mmethod,
⇒ x(x + 6) - 1(x + 6) = 0
⇒ (x + 6)(x - 1) = 0
⇒ x + 6 = 0 or, x - 1 = 0
⇒ x + 6 = 0 ⇒ x = - 6
⇒ x - 1 = 0 ⇒ x = 1
∴ x = - 6 or, 1
