Answer:

If the discrimination of a quadratic function is 13, then the function will have two distinct real roots.

Step-by-step explanation:

Given the quadratic function

[tex]y=ax^2+bx+c[/tex]

where D = b²-4ac is called the discrimination of a quadratic function.

The discriminant D=b²-4ac indicates the type of roots the equation may have.

If D > 0, then the equation has two distinct real roots.

Given that the discrimination of a quadratic function is 13.

i.e. D = 13

Thus, we conclude that if the discrimination of a quadratic function is 13, then the function will have two distinct real roots.

Answer:

the answer is 15$

Step-by-step explanation:

i did 75/5hrs which equal to 15 and if you get 15$ every 5 hrs you will get 75$

Answer:

15

Step-by-step explanation:

Cost over quantity $75 over 5 your going to one so you divide 5 by 5 to get 1 and what ever you do to da bottom u have to do da same to da top so 75 divided by 5 is 15 so 15 is your answer.

The false statement is Negative one-fourth less-than negative two-thirds

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given:

A number line going from negative 1 to 1.

One-half less-than one-third

i.e., 1/2 < 1/3 is true

and, Three-fourths greater-than two-thirds

i.e., 3/4 > 2/3 is true

and, Negative one-fourth less-than negative two-thirds

i.e., -1/4 < -2/3 is false

and, Negative 1 greater-than three-fourths

-1 > -3/4 is true.

They are equal, and thus, the triangle is a right triangle. ... These sides are 6: 8: 10, then the triangle is a right one.

add the two angles withen the triangle and make that equal to the exterior angle

The one that is highlighted

Answer:

The slope is:

[tex]m=-2[/tex]

Step-by-step explanation:

Given the points

Finding the slope between the points using the formula

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(5,\:-11\right),\:\left(x_2,\:y_2\right)=\left(-9,\:17\right)[/tex]

[tex]m=\frac{17-\left(-11\right)}{-9-5}[/tex]

[tex]m=-2[/tex]

Therefore, the slope is:

[tex]m=-2[/tex]

Thus, option A is true.

Answer:

2nd option on the top right

Step-by-step explanation:

Answer:

Option A) angle B = 67°

Step-by-step explanation:

I'll use " [ " symbol for saying angle.

Alright so ...

since triangle ABC and triangle DEF are congruent

it means [ A = [ D

[ B = [ E

[ C = [ F

here [ A = 78° (which means [ D is also 78°)

and ..[ F = 35° (which means [ C is also 35°)

-->So now all you need to know to find [ B is to know the other two angles in the triangle. and thats where ..

you write.. [ A + [ B + [ C = 180° (angle sum property)

78° + [ B + 35° = 180°

113° + [ B = 180°

[ B = 180 - 113

= 67°

I hope that clears the concept , if you have any questions regarding it I'd love to help .

Complete question :

A student forgets to study for an exam consisting of ten multiple choice questions, each with three possible answers. Instead, the student will have to randomly guess, so that there is a 1 3 probability of getting any arbitrary question right. If 6 or more correct answers is a passing score, what is the probability of passing

Answer:

0.07656

Step-by-step explanation:

Given that:

P(correct guess) = 1/3 ; p= 0.33333

Number of questions /trials = 10

P(x ≥ 6) = p(6) + p(7) + p(8) +... + p(10)

This is the sum of the probabilities of getting exactly 6, 7, 8, 9 or 10 questions.

Using the binomial probability calculator to save computation time :

P(x ≥ 6) = 0.07656

I suggest that you use Socratic to solve this.

[tex]\huge\textbf{This equation requires us to do}\\\huge\textbf{distributive property.}[/tex]

[tex]\huge\textbf{If you're unsure what the}\\\huge\textbf{distributive property formula is,}\\\huge\textbf{it is: }[/tex]

[tex]\large\textbf{a(b + c)}[/tex]

[tex]\large\textbf{= a(b) + a(c)}[/tex]

[tex]\large\textbf{= ab + ac}[/tex]

[tex]\huge\textbf{Now, that we have that information}\\\huge\textbf{out of the way, we can find the}\\\huge\textbf{result of your given equation.}[/tex]

[tex]\huge\textbf{Your equation that you provided:}[/tex]
