Factor the polynomial, if possible. If the polynomial cannot be factored, write prime. 100v2 – 324

quester [9]

Answer:

The factored form is:

$4(5v + 9)(5v - 9)$

Step-by-step explanation:

The given expression is:

$100 {v}^{2} - 324$

The Greatest Common Factor is 4:

We factor the GCF to get

$4(25 {v}^{2} - 81)$

We rewrite the expression within the parenthesis as difference of two squares.

$4(( {5v})^{2} - {9}^{2} )$

Recall that: a²-b²=(a-b)(a+b)

This implies that

$4(5v + 9)(5v - 9)$

Subjects for the next presidential election poll are contacted using telephone numbers in which the last four digits are randoml

elixir [45]

Answer: 0.3439

Step-by-step explanation:

Total number of digits : 10

The number of digits except zero =9

The probability of selecting non-zero number :-

$\dfrac{9}{10}=0.9$

Then, the probability that one such phone number , the last four digits do not include any zero:-

$\text{P(no zero )}=(0.9)^4$

Then , the probability that for one such phone number, the last four digits include at least one 0:-

$\text{P(at-least one zero )}=1-(0.9)^4=0.3439$

Hence, the probability that for one such phone number, the last four digits include at least one 0 is 0.3439 .
