Consider the argument: Attached
IS IT VALID OR INVALID?????????????????
Explanation:
The conclusion should be [tex]p \to r[/tex] due to the hypothetical syllogism rule (similar to the transitive rule).
You can make a truth table to show that the premises [tex]p \to q[/tex] and [tex]q \to r[/tex] can both be true at the same time, but the conclusion [tex]p \leftrightarrow q[/tex] is false. Whenever you have all true premises and a false conclusion, then the argument is invalid. True premises must lead to a true conclusion.

The endpoints of CD are C(1, -6)and D(7,5). Find the coordinate of the midpoint, M
Answer:
(4, - 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]
Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then
midpoint = ( [tex]\frac{1+7}{2}[/tex] , [tex]\frac{-6+5}{2}[/tex] ) = [tex]\frac{8}{2}[/tex] , [tex]\frac{-1}{2}[/tex] ) = (4, - 0.5 )

jewels score was 5 over par on the first 1 holes. her score was 4 under on the second 9 holes. what is this but in integers
Answer:
1
Step-by-step explanation:
In golf, if you are over par, then your score is represented by values over zero and with a plus. Since Jewels' score was 5 over on the first hole (dang... that's a quintuple bogey (which is horrible)), she had a +5 on the first hole. But for the next 9 holes, she scored 4 under, which is represented by -4. Add 5 and -4 and you get +1. She still has 8 holes left in that round if she wants to get below par.

Step-by-step explanation:
The inequality is given as the negative 1 < x < 9.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A number x is at least -1 and no more than 9. Then the inequality is given as
- 1 < x < 9

Give your answers as decimals.
The numbers that replace A, B and C on the tree diagram are given as follows:
A = 0.6.B = 0.2.C = 0.7.How to calculate a probability?The parameters that are needed to calculate a probability are listed as follows:
Number of desired outcomes in the context of a problem or experiment.Number of total outcomes in the context of a problem or experiment.Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes.
At each node, the sum of the probabilities is of 1, hence the missing values are given as follows:
A = 0.6, 1 - 0.4 = 0.6 probability of not having a cat.B = 0.2, 1 - 0.8 = 0.2 probability of not having a cat.C = 0.7, 1 - 0.3 = 0.7 probability of not having a cat.Learn more about the concept of probability at https://brainly.com/question/24756209

Critical Thinking You need to know the number of different arrangements possible for five distinct letters. You decide to use the permutations rule, but your friend tells you to use 5!. Who is correct? Explain.
Friend is incorrect and the permutations rule should be used instead of just 5!.
Permutations are a process in which the order of items in a set matters. In other words, it refers to the different arrangements that can be made by selecting r items from n different objects, without repeating any of them.
Calculating permutations manually can be time-consuming.
However, the permutations rule simplifies the process.
The permutations rule states that the number of permutations of n distinct objects, taken r at a time, is equal to
nPr = n!/(n-r)!,
where "n" represents the total number of distinct objects and
"r" represents the number of items selected for each arrangement.
So, if you want to find the number of arrangements possible for five distinct letters, you need to use the permutation rule and not just 5!.
This is because 5! represents the number of ways to arrange five distinct objects (letters) in a line, without restrictions, meaning that the same letter can appear twice, or more, in the arrangement.
However, if the five distinct letters are taken two, three, four, or five at a time, then the permutations rule would have to be used.
For example, the number of different arrangements of two letters out of five distinct letters is equal to
5P2 = 5!/3!
= 5 × 4
= 20.
Therefore, your friend is incorrect and the permutations rule should be used instead of just 5!.

Suppose that the functions > and & are defined for all real numbers x as follows. F (x = 4X S (x) = 3x - 3
Write the expressions for (r-s) (x) and (r+s) (x) and evaluate (r. 3) (3). (r - s) (x) = 0 ( r t s) (xx) = 0 X 5 (r.s) (3) =
The expressions are:
(r-s)(x) = x + 3
(r+s)(x) = 7x - 3
And the value of (r∘s)(3) is unknown without the expression for r(x).
To find the expressions for (r-s)(x) and (r+s)(x) and evaluate (r∘s)(3), where f(x) = 4x and g(x) = 3x - 3, we can substitute these functions into the given expressions.
1. (r-s)(x):
The expression for (r-s)(x) is obtained by subtracting g(x) from f(x):
(r-s)(x) = f(x) - g(x) = (4x) - (3x - 3) = 4x - 3x + 3 = x + 3
2. (r+s)(x):
The expression for (r+s)(x) is obtained by adding f(x) and g(x):
(r+s)(x) = f(x) + g(x) = (4x) + (3x - 3) = 4x + 3x - 3 = 7x - 3
3. Evaluating (r∘s)(3):
(r∘s)(3) means substituting x = 3 into the function composition (r∘s)(x). First, we evaluate s(3):
s(3) = 3(3) - 3 = 9 - 3 = 6
Then, we substitute s(3) into r(x):
(r∘s)(3) = r(s(3)) = r(6)
Since we don't have the expression for r(x), we cannot determine the specific value of r(6) or simplify it further without additional information.
Therefore, the expressions are:
(r-s)(x) = x + 3
(r+s)(x) = 7x - 3
And the value of (r∘s)(3) is unknown without the expression for r(x).

Find the value of a*2 + b*2 when a+b= 6 and ab = 7
Answer:
a² + b² = 22
Step-by-step explanation:
(a + b)² = a² + 2ab + b² ← substitute a + b = 6 and ab = 7
6² = a² + 2(7) + b²
36 = a² + 14 + b² ( subtract 14 from both sides )

The state's congressional and state representative districts were redrawn by the Republican-controlled legislature to favor their party.Shaw v. Reno (1993)The case was in response to the creation of a district in North Carolina that was predominantly Black. This case challenged the constitutionality of the district's odd shape, which critics claimed was created solely to give Black voters an advantage.
