<span>If (x-2) is a factor of polynomial , f(x).Then, it means we can find the zeros or the solutions of the polynomial by putting f(x-2) = 0.Because, the zeros or roots of a polynomial is found by putting f(x)=0, where x is a factor of the polynomial. Example, say f(x)= x^2-2 Which implies, f(x) = (x-2)(x+2) Here, both x-2 and x+2 are the factors of the polynomial. So,x-2 = 0, we get, x=2 is a zero of the polynomial.</span>

In the binomial probability distribution, let the number of trials be n = 4, and let the probability of success be p = 0.3418. U

Lorico [155]

Answer: (a) 0.105 (b) 0.014 (c) 0.119

Step-by-step explanation:

Binomial probability distribution formula :

$P(X=x)= \ ^nC_x p^x(1-p)^{n-x}$ , where x= number of successes, p= probability of success in each trial, n= number of trials.

Given: n= 4 , p= 0.3418

(a)

$P(X=3)=\ ^4C_3(0.3418)^3(1-0.3418)^1\\\\=(4)(0.026282946626)\\\\\approx0.105$

(b)

$P(X=4)=\ ^4C_4(0.3418)^4(1-0.3418)^0\\\\=(1)(0.013648604006)\\\\\approx0.014$

(c)

$P(X= 3\ o\r X=4)= P(X=3) +P(X=4)\\\\=0.105+0.014\\\\=0.119$

You are performing an experiment in your lab. to compare with other experiments your results must be in moles. during your final

Black_prince [1.1K]

4.6 moles in 187 grams of magnesium oxide (mgo).

<h3>What is mole explain with example?</h3>

One mole is defined as the amount of substance containing as many elementary entities (atoms, molecules, ions, electrons, radicals, etc.) as there are atoms in 12 grams of carbon - 12(6. 023×1023).
The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula.
Moles are units used to measure substance amount. Chemistry (Single Science) Atomic structure.

To solve ,

number of moles is equals to the mass in grams divided by RFM

RFM=16+24.3=40.3

=187/40.3

=4.6 moles of MgO
