Using the Law of Detachment, the conclusions are given as follows:
6. No conclusion.
7. ∠AOB and ∠ DOB share one common angle.
What is the Law of Detachment?The Law of Detachment is a logic axiom which states that if a conditional and the hypothesis of a statement are true, then the conclusion of the statement is also true.
Supposing a conditional statement p -> q, we have that the hypothesis and the conclusion are defined as follows:
p is the hypothesis.q is the conclusion.For item 6, we have that the statements are given as follows:
Statement p: You eat a healthy breakfast.Statement q: You are not hungry until lunchtime.We have that p->q and q are true, hence no conclusion can be reached from the law of detachment.
For item 7, we have that the statements are given as follows:
Statement p: Adjacent angles.Statement q: Share one common ray.In this case, we have the hypothesis is true, hence the conclusion is that ∠AOB and ∠ DOB share one common angle.

Hello! Can you, please, explain how to solve this kind of equation "Find m+n, if P(x) = (2m-4)x^2+(5-n)x+13 is constant polynomial".
The value of m + n from getting the values of m and n from the constant polynomial P(x) = (2m - 4)x² + (5 - n)x + 13 is; 7
What is a constant polynomial?
A constant Polynomial is defined as a polynomial is a function of the form f(x) = a
where a is a real number, whose highest degree is zero.
Thus, examples of constant Polynomials are f(x) = 5, g(x) = -11 , h(y) = 7/4
Now, we are given the polynomial expression;
P(x) = (2m - 4)x² + (5 - n)x + 13
From the definition of constant Polynomials, we can say that;
2m - 4 = 0 and 5 - n = 0
Thus;
m = 2 and n = 5
Then, m + n = 2 + 5 = 7

Answer:
£75 > £70 Therefore Sally is wrong.
Step-by-step explanation:
1. First we need to find the volume of the sand pit
60x40x100= 24,000[tex]cm^{3\\[/tex]
Volume= 24,000[tex]cm^{3\\[/tex]
2. We need to convert 8 liters to [tex]cm^{3\\[/tex] so, all the units are the same
1 liter= 1,000[tex]cm^{3\\[/tex]
8 liters= 8,000[tex]cm^{3\\[/tex]
3. We then do 24,000[tex]cm^{3\\[/tex] divide by 8,000[tex]cm^{3\\[/tex] to see how many bags, we need
24,000[tex]cm^{3\\[/tex]/ 8,000[tex]cm^{3\\[/tex] = 30
so, Sally needs 30 bags
4. We know one bag cost £2.50 to know how much 30 bags cost we do
£2.50 x 30 = £75
so, we know 30 bags cost £75
5. Sally statement was said that it would cost less than £70 which is false as it costs £75
6. Therefore the final answer is £75>£70 so Sally is wrong.

Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:
[tex]f^{\prime}(x)=-6x-18[/tex]The solutions for the following equation are the critical points of the original function:
[tex]-6x-18=0\implies x=-3[/tex]The maximum point happens at x = - 3.
To find the corresponding value, we just have to evaluate x = - 3 into our function:
[tex]f(-3)=-3(-3)^2-18(-3)-26=1[/tex]The maximum value of the function is 1, and it occurs at x = - 3.
Answer: The function has a maximum value
The function's maximum value is 1
The function's maximum value occurs at x=-3
Step-by-step explanation:
Given equation: [tex]g(x) = -3x^ - 18x - 26[/tex]
We shall use the differentiation method to find the answer.
Differentiating the equation, we get [tex]g'(x) = - 6x - 18[/tex]
equating g'(x) = 0,
[tex]-6x - 18 = 0\\-6x = 18 \\x = -3[/tex]
Hence the minimum/ maximum value of the function lies in x = -3
on equating x>-3, g'(x) is negative
on equating x<-3, g'(x) is positive
this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value
The function's maximum value at x=-3 is
[tex]g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1[/tex]

Let's use the variable x to represent the price of the television set before taxes.
If the tax rate is 4%, then the original price is multiplied by 1.04, so it is equal 1.04x.
The final price is $520, so we have:

The slope of AB = 2
The slope of CD = 2
Both lines are parallel lines.
How to Determine Parallel and Perpendicular Lines?The lines that are perpendicular to each other have slope values that are negative reciprocal of each other.
For example, if the a line's slope is a, the line that is perpendicular to it will have a slope of -1/a. This is because the negative reciprocal of a is -1/a, and (a)(-1/a) = -1.
On the other hand, the lines that are parallel to each other will have the same slope value.
Given the following:
A(−6 , −9)
B(8, 19)
C(0, −4)
D(2, 0)
Find the slope (m) of AB:
Slope of AB = (19 -(-9))/(8 -(-6))
Slope of AB = 28/14
Slope of AB = 2
Find the slope (m) of CD:
Slope of CD = (0 -(-4))/(2 - 0)

Since the situation can be since as an arithmetic sequence, her salary after 3 years is $73,000. After t years, her salary is a function of t, that is a(t) = 64000 + 3000 t
The given situation can be seen as an arithmetic sequence. The nth term of an arithmetic sequence is given by the formula:
a(n) = a(1) + (n - 1) . d
Where:
a(1) = the first term
d = the common difference.
The problem can be translated into an arithmetic sequence with:
a(1) = $67000
d = $3000
Kylie's salary after 3 years is a(3),
a(3) = a(1) + (3 - 1) . d
a(3) = Kylie's salary + 2 . 3000 = 73000
Hence, after 3 years, Kylie's salary is $73,000
Her salary after t years, means n = t. Therefore,
a(t) = a(1) + (t - 1) . d
a(t) = 67000 + (t -1) . 3000

1-5 Pairs of Angles W.S
The value of x is 26° and y is 9°.
What is linear pair angles ?A pair of neighboring angles created by the intersection of two lines is known as a linear pair of angles. When two angles share a vertex and an arm but do not overlap, they are said to be adjacent angles. Due to their formation on a straight line, the linear pair of angles are always complementary. So, the total of two angles in a pair of lines is always 180 degrees.
The value of x and y are : x= 26° and y= 9°.
As a linear pair, (5x - 17)° + (3x - 11)° = 180°.
or, 8x - 28°= 180°
8x = 180° + 28°
Therefore, the value of x is 26°.
Now,
3x - 11°= 3×26°-11° = 67°
Again,
67°+90°+(2y+5)° = 180° { being linear pair}.
157°+2y+5° = 180°
or, 2y + 162° = 180°
or, 2y = 180° - 162°
y =
Therefore, the value of y is 9°.

For given triangle, the value of x is 22.
In this question, we have been given three angles of triangle.
We need to find the value of x.
We can observe that (6x - 7)° is an exterior angle.
So, the third angle of the triangle is 180° - (6x - 7)°
We know that the sum of the all angles of the triangle is 180°
2x° + (103 - x)° + [180° - (6x - 7)°] = 180°
2x + 103 - x + 180 - 6x + 7 = 180
2x - x - 6x + 103 + 180 + 7 = 180
-5x + 290 = 180
-5x = 180 - 290

Suppose that kellogg believes that the average weight for a box of frosted flakes is 18 ounces. As part of a quality control effort, they sample 30 boxes and find that the mean of those 30 boxes is 18. 2 ounces. Historical records show that the standard deviation of the filling process is 0. 32 ounces. How likely is it for the sample mean to have been 18. 2 ounces or larger if the actual mean is 18 ounces and the standard deviation of the filling process is 0. 32 ounces?.
There is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.
What exactly is mean?In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. For instance, the mean for the set of data 8, 9, 5, 6, 7 is 7, since 8 + 9 + 5 + 6 + 7 = 35, and 35/5 = 7.So, let Y be a random variable with box weights.
μ = 18 ouncesSD = 0.32 ouncesThese are the sample size and mean:
Sample size (n) = 30Sample mean (y) = 18.2N's standard deviation is then roughly followed by Y ( μ = 18, SD = 0.32).
Z score is displayed as:
[tex]z=\frac{\sqrt{n}(y-u)}{S D}[/tex]Where z has a mean of 0 and a standard deviation of 1 and is a normal standard variable.
Given that the standard deviation is given and that sample size n is 30. y roughly follows the Normal distribution.
If the sample mean was 18.2 ounces or more and the actual mean was 18 ounces, the probability that this was the case is given as:
[tex]\begin{aligned}&P[Y \geq 18.2]=P\left[\frac{\sqrt{n(y-u)}}{S D} \geq \frac{\sqrt{30}(18.2-18)}{0.32}\right. \\&=P\left[z \geq \frac{\sqrt{30}+0.2}{0.32}\right] \\&=P\left[z \geq \frac{1.0954}{0.32}\right] \\&=P[z \geq 3.4233] \\&=0.0003\end{aligned}[/tex]
Therefore, there is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.
