Answer with explanation:

→Consider a Polynomial

   \rightarrow ax^n+bx^{n-1}+cx^{n-2}+...........+d

→We will use rational root theorem to find out the factors of the polynomial.

  \rightarrow ax^n+bx^{n-1}+cx^{n-2}+...........+d\\\\\rightarrow a(x^n+\frac{bx^{n-1}}{a} +\frac{cx^{n-1}}{a}+..........+\frac{d}{a})

→Factors of d are

        =\pm 1 , .....\pm d\\\\ \text{Factors of a are}=\pm 1,.....\pm a\\\\ \pm\frac{d}{a}  

⇒Now,substitute these integers that is factors into Polynomial expression to find which expression is equal to Zero.These integers will be factor of Polynomial expression.

For example

 f(x)=x²-3 x+2

By rational root theorem ,roots of the polynomial can be , -1,1,2,-2.

f(1)=1²-3×1+2

   =1-3+2

   =0

f(2)=2²-3×2+2

   =4-6+2

  =0

So, 1 and 2 are root of the polynomial expression.

If we buy 20 pickles what is the experimental probability of winning 5 or more tickets
Mrac [35]

Answer:

Pr = 0.66

Step-by-step explanation:

Given

See attachment for complete question

Required

P(x \ge 5)

From the attachment, we have:

S = 2 + 8 + 4+20+21+19+17+5+2+2

S =100 ---- the sample size

Next, we list out all outcomes more than or equal to 5.

i.e.

x \ge 5

5 is represented with the vertical blue rectangle (with frequency 21).

So, the other elements are to the right of frequency 21.

So, we have:

x \ge 5 = 21+19+17+5+2+2

x \ge 5 = 66

The probability is then calculated as:

Pr = \frac{x \ge 5}{S}

This gives

Pr = \frac{66}{100}

Pr = 0.66
