What is Mathematical Reasoning?Reasoning in maths is the process of applying logical and critical thinking to a mathematical problem in order to work out the correct strategy to use in reaching a solution
A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.
For this conditional statement, P is called the hypothesis and Q is called the conclusion.
“If P then Q” means that Q must be true whenever P is true.
We have a conditional statement If it is raining, we will not play.
Let, P: It is raining and Q: we will not play.
Then; If P is true, that is, it is raining and Q is false, that is, we played, then the statement P implies Q is false.
Hence, conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

The coordinates of the point 3/10 of the way from A to B are _
Answer:
(-1, -4.8)
Step-by-step Explanation:
Let the point be P, which is 3/10 of the way from A to B. This means, it divides P into AP and PB in the ratio, 3:10 = AP/PB = 3/10.
Apply the formula for internal division to find the coordinates which is given as:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
Where,
[tex] A(-4, -8) = (x_1, y_1) [/tex]
[tex] B(9, 6) = (x_2, y_2) [/tex]
[tex] m = 3, n = 10 [/tex]
Plug in the necessary values to find x and y coordinates for point P
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] x = \frac{3(9) + 10(-4)}{3 + 10} [/tex]
[tex] x = \frac{27 - 40}{13} [/tex]
[tex] x = \frac{-13}{13} [/tex]
[tex] x = -1 [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
[tex] y = \frac{3(6) + 10(-8)}{3 + 10} [/tex]
[tex] y = \frac{18 - 80}{13} [/tex]
[tex] y = \frac{-62}{13} [/tex]
[tex] y = \frac{-62}{13} [/tex]
[tex] y = -4.8 [/tex]

One endpoint of a line segment has the coordinates (-5, 12). If the midpoint of the segment is at (2,9), find the
coordinates of the missing endpoint.
Answer:
(9, 6)
Step-by-step explanation:
Midpoint formula is:
x = (x₁ + x₂)/2y = (y₁ + y₂)/2Having coordinates of one end- and midpoint (-5, 12) and (2, 9):
x₁ = -5, y₁ = 12x = 2, y = 9we get the coordinates of the missing endpoint with coordinates (x₂, y₂):
x₂ = 2x - x₁ = 2*2 - (-5) = 4 + 5 = 9y₂ = 2y - y₁ = 2*9 - 12 = 18 - 12 = 6So the missing point is: (9, 6)

A cat welghs 10 pounds. What is the error in the measurement?
5%
1%
2%
Answer:
5%
Step-by-step explanation:
Assuming the measurement is rounded to the nearest pound, there is the potential for the reported value to differ by 1/2 pound from the measured value. The precision of the measurement is thus ...
(0.5 lb)/(10.0 lb) = 5/100 = 5%
__
Unless we know the cat's actual weight, we cannot determine the error in the measurement. If the cat actually weighs 10 pounds, the error is 0%.
Please help quickly!!:)) Appreciate it x+y=6 y+4=x Choices: (11/2, 1/2) (5, 1) (21/2, 11/2) (1, 5)
Answer:
B: (5,1)
Step-by-step explanation:
So we have the system of equations:
[tex]x+y=6\text{ and}\\y+4=x[/tex]
We can solve this system using substitution.
Substitute the second equation into the first. Use x. So:
[tex](y+4)+y=6[/tex]
Combine like terms:
[tex]2y+4=6[/tex]
Subtract 4 from both sides:
[tex]2y=2[/tex]
Divide both sides by 2:
[tex]y=1[/tex]
So, the value of y is 1.
To find x, substitute this back into the second equation:
[tex]y+4=x[/tex]
Substitute 1 for y:
[tex]1+4=x[/tex]
Add:
[tex]x=5[/tex]
Therefore, our answer is (5,1).
The answer is B.

Determine the scale factor for a circle with radius 9 in. to a circle with diameter 24 in. Type your answer as a fraction.
Answer:
bhhhhhhhhhhhhhhhhbhbhb
Step-by-step explanation:
3/4 is the scale factor for a circle with radius 9 in to a circle with diameter 24 in.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The scale factor of a circle to another is the ratio of their radii
Radius of the first circle = 9 in
Diameter of the second circle = 24 in
Radius = Diameter / 2
Radius of the second circle = 24 / 2
Radius of the second circle = 12 in
Scale factor = (Radius of the first circle) / (Radius of the second circle)
Scale factor = 9/12
Scale factor = 3/4
Hence, 3/4 is the scale factor for a circle with radius 9 in to a circle with diameter 24 in.

The height of a helicopter above the ground is given by h=3.00t3, where h is in meters and t is in seconds. After 2.00 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground?S
Answer:
7.96 s
Step-by-step explanation:
Given the following :
h = 3t³
After t seconds, that is, t = 2
h = 3(2)³ = 3 × 8 = 24 m
Rate of change, Velocity = dh/dt
dh/dt = 3*3t^(3 - 1) = 3*3t² = 9t²
At t = 2 s ; initial velocity = 9(2)² = 9 × 4 = 36 m/s
From the 3rd equation of motion:
v² = u² + 2gh
Where g = acceleration due to gravity 9.8m/s
upward motion, g = - ve
Displacement = - 24
v² = 36² + 2(-9.8)(-24)
v² = 1296 + 470.4
v² = 1766.4
v = sqrt(1766.4)
= 42.03 m/s
Since final velocity is in downward direction : take it as negative.
Recall, :
Velocity = Displacement / time
Displacement = Velocity × time
Average Velocity = (Initial + final velocity) / 2
Displacement = - 24 m
-24 = [(36 + (-42.03)) /2] × t
-48 = - 6.03t
t = 48 / 6.03
t = 7.96s

Nadia’s bookshelf contains 10 fiction books, two reference books, and five nonfiction books. What is the probability that she randomly picks up a reference book and then, without replacing it, picks up a nonfiction book?
Answer:
5/136
Probability is the chance of an event happening.
Probability = (Favorable outcome)/(total outcome)
P(r and n) = 2/17 × 5/16
=(2 × 5)/(17 × 16)
= 10/272
= 5/136
Answer:
5/136, or about 3.68%
Step-by-step explanation:
There are 17 total books on the bookshelf and only two of them are reference books, so the probability that you randomly grab a reference book is 2 out of 17, or 2/17.
Now that you took out a reference book (and did not put it back) there are 16 books on the bookshelf and you know five of them are nonfiction. That means the probability of getting a nonfiction book on your second grab is 5/16.
To find the probability that both of these events happen, you multiply the two fractions together.
2/17 x 5/16 = 10/272, which can reduce to 5/136, or about 3.68%
The sample observations on stabilized viscosity of asphalt specimens are 2781, 2900, 3013, 2856 and 2888. Suppose that for a particular application, it is required that true average viscosity be 3000. Does this requirement appear to have been satisfied? State and test the appropriate hypothesis at α = 0.05.
Answer:
there is no sufficient evidence to prove that viscosity is not 3000
Step-by-step explanation:
Let's state the hypothesis.
Null hypothesis; H0: μ = 3000
Alternative hypothesis; μ ≠ 3000
The sample mean is;
x = (2781 + 2900 + 3013 + 2856 + 2888)/5 = 2887.6
Standard deviation σ = √variance = √[(2781 - 2887.6)² + (2900 - 2887.6)² + (3013 - 2887.6)² + (2856 - 2887.6)² + (2888 - 2887.6)²)(1/(5 - 1))]
σ = √((1/4)(11363.56 + 153.76 + 15725.16 + 998.56 + 0.16)
σ = 84.026
Formula for test statistic is given as;
t = (x - μ)/σ
t = (2887.6 - 3000)/84.026
t = -1.338
From online p-value calculator from t value attached, using DF = 5 - 1 = 4, two tail and a significance level of 0.05,we have;
The p-value is 0.251896.
This is greater than the significance level of 0.05.
Thus, we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to prove that viscosity is not 3000

Solve the equation for x. 3x=(2x−2)(m+5)
Answer:
[tex]x=\frac{-2m-10}{-2m-7}[/tex]
Step-by-step explanation:
Step 1: Write out equation
3x = (2x - 2)(m + 5)
Step 2: FOIL
3x = 2xm + 10x - 2m - 10
Step 3: Subtract 2xm on both sides
3x - 2xm = 10x - 2m - 10
Step 4: Subtract 10x on both sides
3x - 2xm - 10x = -2m - 10
Step 5: Factor out x
x(3 - 2m - 10) = -2m - 10
Step 6: Combine like terms in parenthesis
x(-2m - 7) = -2m - 10
Step 7: Divide both sides by -2m - 7
[tex]x=\frac{-2m-10}{-2m-7}[/tex]

The perimeter of the rectangle below is 94 units. Find the length of side PS.
Write your answer without variables.
Answer:
PS = 26 units
Step-by-step explanation:
Perimeter of rectangle = 94
2(4z - 2 + 3z) = 94
2(7z - 2) = 94
14z - 4 = 94
14z = 94 + 4
14z = 98
z = 98/14
z = 7
QR = 4z - 2 = 4*7 - 2 = 28 - 2 = 26
PS = QR (Opposite sides of rectangle)
PS = 26 units
