Answer:

Option (d) is correct.

For the given polynomial p(x)  if 3 +4i is a root then, 3 - 4i is also the root of p(x).

Step-by-step explanation:

Consider the given polynomial equation p(x) = 0

It is given that the polynomial P(x) has one root 3 + 4i

According to Complex conjugate theorem ,  if V is a polynomial and x + iy is a root of given polynomial then  its conjugate x - iy is also the root of the polynomial.

Thus, for the given polynomial p(x)  if 3 +4i is a root then, 3 - 4i is also the root of p(x).

Thus, option (d) is correct.

Answer:

Each =\pounds 1121

Step-by-step explanation:

See comment for complete question.

Given

Total =  \pounds 8968

Projects = 8

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

Each =\frac{Total}{Projects}

Each =\frac{\pounds 8968}{8}

Each =\pounds 1121

<em>Each project gets £1121</em>

Approximately 85% of persons age 70 to 84 live in their own household and are income-qualified for home purchases.
miv72 [106K]

Answer:

The probability that exactly two of the four live in their own household and are income-qualified is  = .0975

Step-by-step explanation:

Given -

Approximately 85% of persons age 70 to 84 live in their own household and are income-qualified for home purchases.

Probability of sucess ( p ) = 85% =.85

Probability of failure ( q ) = 1 - .85 =.15

n = 4

From combination of n events taking r sucess we use binomial distribution

P(X = r) = \binom{n}{r}p^{r}q^{n-r}

where , r = 2

the probability that exactly two of the four live in their own household and are income-qualified is =

P(X = 2) = \binom{4}{2}0.85^{2}0.15^{4 - 2}

                = \frac{4!}{(2!)(2!)} \times 0.7225  \times .0225

                 = 6 \times 0.7225  \times .0225

                 = .0975
