Answer:

equation has no solutions

Step-by-step explanation:

3|–3x + 9| = –18 (divide both sides by 3)

|–3x + 9| = –6

because by definition, for any value a, |a| must be non-negative

hence |–3x + 9| must give a value that is greater or equal zero

because the right side of the equation is a negative integer, hence the equation has no solutions.

aniked [119]

Answer:

Option a - $xy^2+5$

Step-by-step explanation:

Given : Polynomial $x^3y^2+8xy^2+5x^2+40$

To find : Select one of the factors of polynomial ?

Solution :

The polynomial $x^3y^2+8xy^2+5x^2+40$

We factor of above polynomial by taking common terms,

$xy^2(x^2+8)+5(x^2+8)$

$(xy^2+5)(x^2+8)$

From the given options,

$xy^2+5$ is one of the factors of polynomial.

Therefore, option a is correct.

Suppose a six-sided die is tossed 1200 times and a 6 comes up 419 times. (a) Find the empirical probability for a 6 to occur. (E

krok68 [10]

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

$=\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349$

Probability = 0.349

b) Theoretical Probability:

$=\frac{1}{6}$

Here both probabilities are not equal.

Therefore the die is not fair and biased.
