Step-by-step explanation:
We need to find 175% of 12. We can do this by multiplying 12 by 1.75. 12x1=12 and 12x0.75=9 and 12+9=21.
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>
<span>C. 2x^2- 16x +30 <--- answer </span>
F(3)= 9 bc 4(3)=12 12-3=9
Scalene right triangle-
None of the angles are congruent so it’s scalene, but since a it has a 90 degree angle it is also a right triangle
