An irreducible quadratic factor is an irreducible factor that is quadratic or has the highest exponent of 2.

An irreducible quadratic factor is an irreducible factor that is quadratic or has the highest exponent of 2.

A nonlinear equation is one in which the maximum degree of a term is two or more than two. When the polynomial equation is with degree two, then it is called a quadratic equation, and it is represented by a standard expression;

[tex]\rm ax^2+bx+c=0[/tex]

Where a is not equal to 0.

The degree of the polynomial is 2.

A quadratic polynomial can be further divided into linear factors. Now, simplify one of the quadratic expressions by completing the square method, which gives two linear factors.

Hence, an expression that gives the degree of the polynomial is [tex]\rm ax^2+bx+c=0[/tex].

The probability that a randomly selected student studies more than 27 hours per week is 0.0014.

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of a population

N = number of observations of population

X = mean

μ = population mean

The average number of hours that NAU students spend studying each week is normally distributed with a mean of 25 hours and a standard deviation of 2.5 hours.

So, μ = 25

σ  = 2.5 hours.

[tex]P(X > 27) = P(\frac{x-\mu}{\sigma} } > \frac{27-25}{2.5})\\\\= P(z } > \frac{27-25}{2.5})\\\\[/tex]

= P (z > 1.2)

= 1 -  P (z < 1.2)

Answer:

[tex]12x - 3y = 6[/tex]

Step-by-step explanation:

Standard form is written this way: [tex]Ax+By=C[/tex]

However, in this case, we just have to simplify 8x-3y=6-4x, as it is already mostly in standard form.

So, to do this, we have to combine like terms.

The only like terms that can be combined are -4x and 8x.

So, we add 4x to both sides, and we get: [tex]12x - 3y = 6[/tex].

Answer:

3

Step-by-step explanation:

2(x + 1) = 3(5 - x) + 2

Distribute,

2(x + 1) = 3(5 - x) + 2

2x + 2 = 3(5 - x) + 2

Rearrange terms,

2x + 2 = 3(5 - x) + 2

2x + 2 = 3(-x + 5) + 2

Distribute,

2x + 2 = 3(-x + 5) + 2

2x + 2 = -3x + 15 + 2

Add the numbers,

2x + 2 = -3x + 15 + 2

2x + 2 = -3x + 17

Subtract 2 from both sides,

2x + 2 = -3x + 17

2x + 2 - 2 = -3x + 17 - 2

2x  = -3x + 17 - 2

2x  = -3x + 15

Add 3x to both sides,

2x  = -3x + 15

2x + 3x  = -3x + 3x + 15

5x  = -3x + 3x + 15

5x  =  15

Divide both sides by the same factor (15),

5x  =  15

5x/5 = 15/5

x = 15/5

x = 3

Hence, the answer is 3.

Answer:

the vertex represents a maximum

Vertex is (4,7)

Step-by-step explanation:

Given the function [tex]f(x)=-x^2+8x+9[/tex]

Equation is in the form of y=ax^2+bx+c

[tex]a=-1[/tex]

When 'a' is negative, then vertex is maximum

when 'a' is positive, then vertex is minimum

Answer:

pickup b

Step-by-step explanation:

Unit conversion :

1 kilogram is about 2.20462262 pounds

Solving :

⇒ Let's convert pickup b's mass into pounds

⇒ mass (pickup b) = 685 × 2.20462262

⇒ mass (pickup b) = 1510 pounds (approximately)

Clearly :

⇒ 1500 < 1510

⇒ mass (pickup a) < mass (pickup b)

Hence, pickup b weighs more.

Goblin Birt can take 15 minutes to count the coins in the bag by himself.

The unitary method is a process for solving a problem by first finding the value of a unit, and then finding the necessary value by multiplying the single unit value.

How to calculate how long would it take goblin Birt to count the coins in the bag by himself?

In this problem, the unitary method is to be applied three times.

Here, counting all the coins is considered as the entire work which is considered as 1.

According to the problem,

Goblin guys can count the coins in a bag in 10 minutes.

In 10 minutes Goblin guys can count the coins in the bag.

In 1-minute Goblin, guys can count th part of the coins in the bag.

Again, according to the problem,

Goblin gryh and Goblin Birt both can count all the coins in 6 minutes.

In 6 minutes, Goblin gryh and Goblin Birt both can count all the coins in the bag

In 1 minute, Goblin gryh and goblin Birt both can count  th  part of the coins in the bag.

In 1 minute, Goblin Birt can count ([tex]\dfrac{1}{6}-\dfrac{1}{10}[/tex]  th part of the coins in the bag.

[tex]= (\dfrac{5-3}{30})=\dfrac{1}{15}[/tex] th part of the coins.
