The statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.
What is a contingency statement?Contingency is a statement in which there are some true and some false values for every value of its propositional variables.
The statement given is (p and (p => q)) => q), or in more symbolic way, it is: ((p ∧ (p → q)) → q)
Now, let we evaluate it for p = False, and q = False.
Then we get:
(p → q) = T (as False implied False)
Now, (p ∧ (p → q)) is F and T which is F
Then, ((p ∧ (p → q)) → q) is F → F which is True, or T.
Thus, p = F,and q = F makes ((p ∧ (p → q)) → q) = T
Similarly, the truth table for the statement (p and (p => q)) => q) or simply ((p ∧ (p → q)) → q) is:
p q ((p ∧ (p → q)) → q)
F F T
F T T
T F T
T T T
Since all the values are true, thus, this isn't a contingency.
Thus, the statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.

If the spinner below is spun twice, find the probability that it lands on N, then a vowel.
Answer:
0.29 or 29%
Step-by-step explanation:
There are 7 options per spin. Of which 3 vowels.
For 2 spins, total spins is 14.
conditions:
First spin is 1/7
Second spin is 3/7
so,
4/14 = 0.29 or 29% I think

A model house has a scale of
lin: 2ft. If the real house is 26 ft
wide, then how wide is the
model house?
Answer: Assuming that you mean 1in:2ft the model house would be 13 inches wide.
Step-by-step explanation: well 1 is half of 2 right? So if you want to get the numbers easier to use then just divide that 26 by 2 and then you get the scale 1in:1ft. From there it is easy, 13 feet of the real house= 13 inches in the model house

In AABC, m ZA=36° and m ZB =92°. What is M
?
m∠C = 52°
The total interior angle of a triangle sum ups to 180°Solve:
m∠A + m∠B + m∠C = 180°
36° + 92° + m∠C = 180°
m∠C = 180° - 92° - 36°
m∠C = 52°
Answer:
m∠C = 52°Step-by-step explanation:
Angle Sum Property
∠A + ∠B + ∠C = 180°Here we have :
∠A = 36°∠B = 92°Solving :
36° + 92° + ∠C = 180°∠C + 128° = 180°∠C = 52°Simplify the radical expression. [tex]\sqrt{400/5}[/tex]

The value of PN is 7.5 if the triangles KLJ and NPM are similar triangles.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles KLJ and NPM are similar triangles.
So the sides of triangle are proportional.
KL/JL = PN/PM
Substitute the values:
5/6 = PN/9
Apply cross multiplication:
45=6PN
Divide both sides by 6:
45/6= PN
7.5=PN
Hence, the value of PN is 7.5.

a) x+y = 70b) The graph is shown below. The lines intersect at (20, 50) meaning that she has 20 quarters and 50 dimes.========================================================
Explanation:
a)
x = number of quarters
y = number of dimes
x+y = number of dimes and quarters
x+y = 70 coins total
-----------
b)
Use a graphing tool like Desmos or Geogebra to plot each linear equation on the same xy grid. I'm using Geogebra to get what is shown below.
The red line 25x+10y = 1000 goes through (0,100) and (40,0)
The blue line x+y = 70 goes through (0,70) and (70,0)
The two lines intersect at (x,y) = (20,50)
This means x = 20 and y = 50 pair up together.
Kateri has 20 quarters and 50 dimes
20 quarters = 20*25 = 500 cents = 500/100 = $550 dimes = 50*10 = 500 cents = 500/100 = $5Total value = $5 + $5 = $10
Also note that 20 quarters + 50 dimes = 70 coins total
Both conditions have been confirmed.

Answer: 34 cm^2.
Step-by-step explanation: To find the area of a trapezoid, you need to add base 1 and base 2, multiply the height, and divide it all by 1/2. The steps are done below:
Find base 1, base 2, and the height: To find base 1 and base 2, you find the top and bottom lengths of the trapezoid. 5 is the top and 12 is the bottom of the trapezoid. You can assign whichever base to whichever number, as long as base 1 and base 2 have a number. For this problem, we'll assign 5 for base 1 and 12 for base 2. To find the height, you need to find the height of the trapezoid, which is 4.Make an equation: The equation should look like the following... 5 (base 1) + 12 (base 2) x 4 (height) / 1/2.Solve: The first thing you should do when solving is to add the bases together, which is 17. Next multiply the height which is 4, by 17, which is 68. Lastly divide 68 by 2, which can be done in two ways. You can either simply divide 68 by 2 or multiply 68 by 1/2, which will both give you the same answer. 68 x 1/2 = 34.Therefore, your answer is 34 cm^2. There's an image below if you need additional information.

Tell whether the triangle with the given side lengths is a right triangle
14mm, 19mm, 23mm
Answer:
not a right triangle
Step-by-step explanation:
The side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem:
c² = a² +b²
23² = 14² +19²
529 = 196 +361
529 = 557 . . . . . . . . not true; not a right triangle
__
The longest side (23 mm) is too short for a right triangle, so the angle opposite will be smaller than 90°. This is an acute triangle.
