Which of the following is written as a rational function? a. G(x)=-4x b. P(x)=7x 1 c. F(x)=x-5/3x d. Q(x)=x^2 6x-3.

slavikrds [6]

The function can be expressed as a rational function is $\rm\dfrac{x-5}{3x}$ .

We have to determine

Which of the following is written as a rational function?

According to the question

A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.

A rational function can be expressed as;

$\rm Rational \ function =\dfrac{p(x)}{g(x)}$

Then,

The required rational function is expressed as;

$\rm Rational \ function =\dfrac{p(x)}{g(x)}$

Where p(x) is (x-5) and g(x) is 3x.

Therefore,

The function is,

$\rm Rational \ function =\dfrac{x-5}{3x}$

Hence, the function can be expressed as a rational function is $\rm\dfrac{x-5}{3x}$ .

A bag contains white marbles and yellow marbles, 24 in total. The number of white marbles is 9 less than 2 times the number of y

Zinaida [17]

There are 13 white marbles in the bag.

Step-by-step explanation:

Given,

Total number of marbles = 24

Let,

x represent the number of white marbles.

y represent the number of yellow marbles.

According to given statement;

x+y=24 Eqn 1

x = 2y-9 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(2y-9)+y=24\\2y-9+y=24\\3y=24+9\\3y=33$

Dividing both sides by 3

$\frac{3y}{3}=\frac{33}{3}\\y=11$

Putting y=11 in Eqn 2

$x=2(11)-9\\x=22-9\\x=13$

There are 13 white marbles in the bag.

An insurance company found that 9% of drivers were involved in a car accident last year. If seven drivers are randomly selected,

zzz [600]

Answer: 0.1061

Step-by-step explanation:

Given : An insurance company found that 9% of drivers were involved in a car accident last year.

Thus, the probability of drivers involved in car accident last year = 0.09

The formula of binomial distribution :-

$P(X=x)^nC_xp^x(1-p)^{n-x}$

If seven (n=7) drivers are randomly selected then , the probability that exactly two (x=2) of them were involved in a car accident last year is given by :-

$P(X=2)=^7C_2(0.09)^2(1-0.09)^{7-2}\\\\=\dfrac{7!}{2!5!}(0.09)^2(0.91)^{5}=0.106147867882\approx0.1061$
