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.

Step-by-step explanation:

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

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.

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

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 .

Answer:

Step-by-step explanation:

3 (x – 4) = 2x + 6                  Remove the brackets

3x - 12 = 2x + 6                    Add 12 to both sides.

3x - 12 + 12 = 2x + 6 + 12     Combine

3x = 2x + 18                         Subtract 2x from both sides

3x-2x = 2x-2x + 18              Combine

x = 18
