Find a polynomial with integer coefficients, with leading coefficient 1, degree 5, zeros i and 5- i, and passing through the ori

V125BC [204]

For a polynomial with real cofieints, if a+bi is a root, a-bi is also a root

zeros, i and 5-i

passes through origin means 0 is also a zero

get plus and minus of the roots

i, -1, 5-i, 5+i and 0 are roots

for a poly with roots, r1,r2,r3,r4,r5, the facotred form is

(x-r1)(x-r2)(x-r3)(x-r4)(x-r5)

sub the roots

(x-i)(x-(-i))(x-(5-i))(x-(5+i))(x-0)=

(x-i)(x+i)(x-5+i))(x-5-i))(x)=

x(x^2+1)(x^2-10x+26)=

x^5-10x^4+27x^3-10x^2+26x

the polynomial is f(x)=x^5-10x^4+27x^3-10x^2+26x

SashulF [63]

Answer:

3972.72 specimens

Step-by-step explanation:

We solve using the z score formula:

z = (x-μ)/σ where

x is the raw score = 73 cm

μ is the population mean = 147 cm

σ is the population standard deviation = 30 cm

N is the number of samples = 4000

For x > 73

z = 73 - 147/30

z = -2.46667

Probability value from Z-Table:

P(x<73) = 0.0068189

P(x>73) = 1 - P(x<73) = 0.99318

The probability of having a height greater than 73cm is: 0.99318

The number of specimens that have a height greater than 73cm is calculated as: 0.99318 × 4000

= 3972.72 specimens

-7/3x+11 i need help

Len [333]

Answer:

$\frac{33-7x}{3}$

Step-by-step explanation:

We want to simplify the algebraic expression:

$-\frac{7}{3}x+11$

We can rewrite this as:

$-\frac{7}{3}x+\frac{11}{1}$

We convert to equivalent fractions to get::

$-\frac{7}{3}x+\frac{33}{3}$

We can now add the numerators and keep one of the denominators.

$-\frac{7x+33}{3}$

We rewrite as:

$\frac{33-7x}{3}$
