Carlos is using the quadratic formula to find the solutions of y=3x^2-5x-2. Which of the following will simplify to the correct solutions? (options on photo)

Answers

Answer 1

Answer:

Answer:

$Fx=(5\pm√(25+24) )/(6)$

Step-by-step explanation:

A quadratic equation in one variable given by the general expression:

$ax^2+bx+c$

Where:

$a\neq 0$

The roots of this equation can be found using the quadratic formula, which is given by:

$x=(-b\pm√(b^2-4ac) )/(2a)$

So:

$y(x)=3x^2-5x-2=0$

As you can see, in this case:

$a=3\nb=-5\nc=-2$

Using the quadratic formula:

$x=(-b\pm√(b^2-4ac) )/(2a)=(-(-5)\pm√((-5)^2-4(3)(-2)) )/(2(3))=(5\pm√(25+24) )/(6)$

Therefore, the answer is:

$Fx=(5\pm√(25+24) )/(6)$

paul paints a room in 6 hours. joel paints the room in 3 hours. how long will it take them to paint togather?

Answers

Paul paints 1/6 of the room each hour.
Joel paints 1/3 of the room each hour.

Working together, they paint (1/6 + 1/3) of the room each hour.

In order to add the fractions, you need a common denominator.
6 will work:

(1/6 + 1/3) = (1/6 + 2/6) = 3/6 = 1/2

Together, they can paint at the rate of 1/2 room/hour .

This rate of work produces 2 hour/room.

$(1)/(6)+(1)/(3)=(1)/(x)\n (1)/(6)+(2)/(6)=(1)/(x)\n (3)/(6)=(1)/(x)\n (1)/(2)=(1)/(x)\n x=2$

Answers

Answer:

The binomial distribution is called a probability distribution. This is a common discrete distribution that was used in the statistics.

Step-by-step explanation:

The binomial distribution is also named as a probability distribution. It is explained as the likelihood of the value will take the value of the two independent variables under the given parameters.

The binomial distribution is commonly called the discrete distribution. it is opposite to the normal distribution. The binomial distribution counts the two states which are represented as 1 and 0. It is usually used in social science statistics.
