Answer my question:

Answer ASAP <Will mark brainiest>

a) Starting with

(¬r ∧ p ∧ q) ∨ (¬r ∧ ¬p ∧ q)

distribute the disjunction (∨) :

((¬r ∧ p ∧ q) ∨ ¬r) ∧ ((¬r ∧ p ∧ q) ∨ ¬p) ∧ ((¬r ∧ p ∧ q) ∨ q)

and once more among the grouped statements:

(¬r ∧ p ∧ q) ∨ ¬r ≡ (¬r ∨ ¬r) ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)

(¬r ∧ p ∧ q) ∨ ¬p ≡ (¬r ∨ ¬p) ∧ (p ∨ ¬p) ∧ (q ∨ ¬p)

(¬r ∧ p ∧ q) ∨ ¬p ≡ (¬r ∨ q) ∧ (p ∨ q) ∧ (q ∨ q)

So, the original statement is equivalent to

[(¬r ∨ ¬r) ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)] ∧ [(¬r ∨ ¬p) ∧ (p ∨ ¬p) ∧ (q ∨ ¬p)] ∧ [(¬r ∨ q) ∧ (p ∨ q) ∧ (q ∨ q)]

which reduces to

[¬r ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)] ∧ [(¬r ∨ ¬p) ∧ (q ∨ ¬p)] ∧ [(¬r ∨ q) ∧ (p ∨ q) ∧ q]

and further to

¬r ∧ (p ∨ ¬r) ∧ (¬r ∨ ¬p) ∧ (q ∨ ¬p) ∧ (p ∨ q) ∧ q

For any statements X and Y, we have the identity

• X ≡ (X ∨ Y) ∧ (X ∨ ¬Y)

so another step of simplification reduces the underlined expressions to

¬r ∧ ¬r ∧ q ∧ q

which leaves us with

¬r ∧ q

###

b) Recall the identity,

p ⇒ q ≡ ¬p ∨ q

Then

(p ⇒ q) ⇒ q ≡ (¬p ∨ q) ⇒ q ≡ ¬(¬p ∨ q) ∨ q

Distributing the negation gives

(p ⇒ q) ⇒ q ≡ (p ∧ ¬q) ∨ q

and distributing the disjunction gives

(p ⇒ q) ⇒ q ≡ (p ∨ q) ∧ (¬q ∨ q)

from which it follows that

(p ⇒ q) ⇒ q ≡ p ∨ q

Answer:

1152.48

Step-by-step explanation:

1176-(2%×1176)

= 1176-23.52

= 1152.48

The value of x is found to be -4.

A function y = f(x) is a one to one relation between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

Given function is as below,

f(x) = 4x + 11                (1)

And, f(x) = -1

Substitute the value of f(x) in equation (1) to obtain,

-1 = 4x + 11

=> 4x = -1 - 11

=> x = -12/3

       = -4

Hence, the value of x is obtained as x = -4.

The total area of the three-petal motif is [tex]93937cm^2[/tex]

The three petal motif has the structure shown in the accompanying image. the dark gray area is the equilateral triangle. The light gray areas are the major segments of each of the circles.

The area of the three-petal motif, then, is the sum of the area of the equilateral triangle and the three major segments (all of which have the same area)

From the second image

Area of equilateral triangle = [tex]16129cm^2[/tex]

Area of each major segment = [tex]25936cm^2[/tex]

Therefore,

Area of three-petal motif = [tex]16129cm^2+3(25936cm^2)=93937cm^2[/tex]

Using quadratic function concepts, it is found that the discriminant is zero, hence option A is correct.

A standard quadratic equation is modeled by:

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

The relation between the discriminant and the number of zeros(roots) is:

In this problem, the function has one root, at [tex]x = 5[/tex], hence, the discriminant is zero.

Answer:

It should be -3.125%

Step-by-step explanation:

(124 - 128)/128 × 100

-4/128 × 100 = -3.125%

Answer:

25

Step-by-step explanation:

To model the situation, we can write an equation. 16% of a number is the same as multiplying it by 0.16. Naming the number x, we are give that 16% of it is 4:

0.16x = 4

Dividing by 0.16 on both sides we get:

x = 25

(x1, y1) and (x2, y2)

(2, 3) and (6,8)

slope = y2 - y1 / x2 - x1

= 8 -3 / 6 - 2

3.7x+2.5y .

Step-by-step explanation:

i did the quiz.

The sum of two given algebraic expressions is  3.7x+2.5y. Therefore, option A is the correct answer.

Given that, (2.3x−1.2y)+(1.4x+3.7y).

Addition of Algebraic Expressions is the process of collecting like terms and adding them. Identify and add the coefficients of like terms and sum them to find the final expression of given problems.

Now, (2.3x−1.2y)+(1.4x+3.7y)

= 2.3x+1.4x-1.2y+3.7y

= 3.7x+2.5y

The sum of two given algebraic expressions is  3.7x+2.5y. Therefore, option A is the correct answer.

Answer:

Step-by-step explanation:

6)For question 6 you have the right idea but as the new image is bigger than the pre-image the scale factor would be 3/1

7)You have the right answer but the fraction can be simplified to 2

8)I think this question is asking for the angle in the triangle on the left that is the same as the one on the right so from left to right,

F=R         G=S       H=T

FG=RS   GH=ST   FH=RT

9)The scale facto for the longest edge here is 2 but the scale factor for the shortest edge is 18/8 which is equal to 9/4 so the are not congruent as they have two different scale factors. Answer) no

10) the triangles are similar as angle a=n and 55+35+90 = 180 so yes they are similar

Answer:

0. 20

Step-by-step explanation:

According to the information given, using the z-distribution, it is found that a sample of 1066 is needed.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions, according to the z-distribution.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, the estimate is of 52%, hence [tex]\pi = 0.52[/tex].

95% confidence level

So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].  

The minimum sample size is n for which M = 0.03, hence:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.52(0.48)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.52(0.48)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.52(0.48)}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.52(0.48)}}{0.03})^2[/tex]

[tex]n = 1065.4[/tex]

Rounding up, a sample of 1066 is needed.
