Answer:
Step-by-step explanation:
Let f(x) be the polynomial function of minimum degree with real coefficients whose zeros are 5, -3, and -1 + 3i be f(x).
By the complex conjugate property of polynomials, -1-3i is also a root of this polynomial.
Therefore the polynomial in factored form is 
We expand to get:
We expand further to get:\
Answer:
0.4629
Step-by-step explanation:
Using the binomial probability relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Number of trials, n = 25
Probability of having defective tablet greater than 3 p(x ≥ 3) ;
p = 0.10 ;
1 - p = 1 - 0.10 = 0.90
P(x ≥ 3) = P(x = 3) + p(x = 4) +.... + p(x = 25)
Using a binomial probability calculator :
P(x ≥ 3) = 0.4629
Therefore, the probability that shipment would be sent back to the vendor is 0.4629

Answer:
Mr Bean will get 1000 naira.
Step-by-step explanation:
