It can be inferred that H0: ? = 15, Ha: ? = 15 doesn't comply because both hypothesis use an equal sign.
How to illustrate the hypothesis?From the information, H0: p = 0.5, Ha: p > 0.6 doesn't comply because the two hypothesis use different numbers.
Furthermore, H0: ? = 121, Ha: ? < 121 shows that the pair complies. Also, H0: ? = 123, Ha: ? = 125 doesn't comply as they use the equal sign and different numbers.
Lastly, H0: p? = 0.2, Ha: p? ? 0.2 doesn't comply because p is not a population characteristic.

if p and q are two propositions,use truth table technique to show that a) (p=q) ^ (q=p)= p=q and b) [(p=q) ^ p]=q is a Tautology
Answers
Answer:
see attached
Step-by-step explanation:
The truth table technique shows the first proposition is True. However, the second proposition cannot be shown to be a tautology, because it isn't true.
__
a.The "equals" relation is commutative: (a=b) ≡ (b=a), hence the expression ...
(p=q)∧(q=p)
is equivalent to
(p=q)∧(p=q)
We know that the And of p with itself is just p, so that fact ensures the truth of ...
(p=q)∧(p=q) = (p=q)
Hence
(p=q)∧(q=p) = (p=q)
The top truth table in the attached shows the final comparison of the two expressions is true for all values of p and q.
__
b.The attached truth table shows that the given relation is not a tautology.

An equation is shown below:
6(2x - 11) + 15 = 21
Write the steps you will use to solve the equation and explain each step.
Answers
Answer:
x=6
Step-by-step explanation:
The first thing you should start with is distributing the 6 inside the parentheses, which would give us (12x - 66) + 15 = 21. Now we can add like terms on this side of the equation to get: 12x -51 = 21. Add the 51 to the right side to get 12x = 72, then divide both sides by 12 to get x = 72/12 or 6.
x=6

Rectangle PQRS is plotted on a coordinate plane. The coordinates of P are (– 1, 4) and the
coordinates of Q are (– 1, – 4). Each unit on the coordinate plane represents 1 centimeter, and
the area of Rectangle PQRS is 64 square centimeters. Find the coordinates of Points R and S
given these conditions:.aPoints R and S are to the left of Points P and Q.bPoints R and S are to the right of Points P and Q
Answers
Answer:
See belowStep-by-step explanation:
Given points P and Q have same x-coordinate but different y- coordinates.
The distance between P and Q is the difference of y- coordinates:
PQ = 4 - (-4) = 8 units = 8 cmThe area is 64 cm², it means the adjacent sides are
PS = QR = 64/8 = 8 cma)
If the points R and S are to the left, their coordinates are
S = (-1 - 8, 4- 0) = (- 9, 4)R = (-1 - 8, - 4 - 0) = (- 9, -4)b)
If the points R and S are to the right, their coordinates are
S = (-1 + 8, 4 + 0) = (7, 4)R = (-1 + 8, - 4 + 0) = (7, -4)Answer:
Points R and S are to the left of Points P and Q
R = (-9, 4)
S = (-9, -4)
Points R and S are to the right of Points P and Q
R = (7, 4)
S = (7, -4)
Step-by-step explanation:
Given coordinates:
P = (-1, 4)Q = (-1, -4)Points P and Q have the same x-value.
The vertical distance between these two points is:
[tex]\begin{aligned}\implies \sf y_P-y_Q & =\sf 4-(-4)\\ & =\sf 4+4\\ & =\sf 8\:units \\ & =\sf 8\:cm\end{aligned}[/tex]
Area of a rectangle = width × length
If the area of the rectangle PQRS is 64 cm² then:
[tex]\begin{aligned} \implies \sf 64 & = \sf width \times 8\\\implies \sf width & = \sf \dfrac{64}{8}\\\implies \sf width& = \sf 8 \: cm \end{aligned}[/tex]
This means that the y-values of points R and S will be the same as points P and Q, but the x-values will either be 8 less or 8 more.
Points R and S are to the left of Points P and Q
R = (-1 - 8, 4) = (-9, 4)
S = (-1 - 8, -4) = (-9, -4)
Points R and S are to the right of Points P and Q
R = (-1 + 8, 4) = (7, 4)
S = (-1 + 8, -4) = (7, -4)

If you can buy 15 bags of potatoes for $20, then how many can you buy with $4?
Answers
Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.
OR
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags.
Answer:
Step-by-step explanation:
Remark
This is a proportion problem. It assumes that if you know 3 of the four parts of a 2 ratio proportion, you can solve for the 4th one.
Givens
number of bags = 15
Cost = 20
Different cost = 4
number of bags = ?
Formula
Number of bags / Cost = different number of bags/ New Cost
Solution
15/20 = x / 4 Multiply both sides by 4
15*4/20 = x / 4 * 4
60/20 = x
Answer x = 3
That is 4 dollars gets you 3 bags of potatoes
An observation tower is 65m high. A support wire is attached to the tower 30m from the top. If the support wire and the ground form an angle of 56 degrees, what is the length of the support wire, to the nearest tenth?
Answers
The support wire is the hypotenuse of the right triangle formed. Therefore, the length of the support wire is 42.2 meters.
The situation forms a right angle triangle.
Right angle triangleA right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore, the height of the tower where the wire was attached is the opposite side of the triangle formed.
The wire was attached 30 m from the top. Hence, 65m - 30m = 35 m.
Therefore,
sin 56° = opposite / hypotenuse
sin 56° = 35 / x
The hypotenuse is the length of the support wire.
Therefore,
x = 35 / 0.82903757255
x = 42.2195416164
x = 42.2 m

In parallelogram ABCD, mLA
4x + 20 and m2C = x + 26
Find the value of x.
Then find the measure of LA.
Answers
Answer:
Step-by-step explanation:
In a parallelogram, opposite angles are congruent.
∠A = ∠C
4x + 20 = x + 26
Step 1: To find the valu of 'x', first subtract 20 from both sides
4x = x + 26- 20
4x = x + 6
Step2: Now, subtract 'x' from both sides
4x -x = 6
3x = 6
Step:3: divide both sides by 3
x = 6/3
x = 2
∠A = 4*2 + 20
= 8 + 20
∠A = 28°

B: 2x+90=180
C: x-90=180
D: Not enough info
Answers
Answer:
(B) 2x + 90 = 180 is an equation that could be used to find x.
Step-by-step explanation:
Observing at the triangle, we can see that..
- We are aware of two angel measurements, both of which are 45 degrees.
One triangle is exactly 180 degrees and if you add both 2 angel measurements from the triangles...
45 + 45 = 90 degrees
180 - 90 = 90 degrees
As a result, we know that x = 90. Now we find the equation. Lets look at equation B. ( 2x + 90 = 180 )
Step 1 : 90 should be subtracted from both sides.
2x + 90 − 90 = 180 − 90
2x = 90
Step 2 : Divide both sides by 2.
(When I use the symbol /, it signifies I'm dividing.)
2x/2 = 90/2
x = 45
Step 3: Examine your solution to see whether it is right.
2x + 90 = 180
2(45) + 90 = 180
90 + 90 = 180 ✓
This shows that 2x + 90 = 180 is an equation that could be used to find x.
