The answer to the first, third and fourth part is inductive reasoning and the answer to the second and fifth part is deductive reasoning.
The first example is an example of Inductive reasoning because it is based on a pattern or trend of a sequence of numbers (2, 4, 6, 8) and uses that pattern to make a prediction or generalization about the next number in the sequence (10). This is a common use of inductive reasoning, where observations or data are used to make generalizations about future events or situations.
The second example is an example of Deductive reasoning because it starts with a general statement (all plants need water) and applies it to a specific case (Water Hyacinth) to reach a logical conclusion (Water Hyacinth needs water). This is the classic form of deductive reasoning, where the conclusion follows logically from the premises and can be proven to be true if the premises are true.
The third example is an example of Inductive reasoning because it is based on a pattern or trend of a sequence of numbers (dots in squares) and uses that pattern to make a prediction or generalization about the next number in the sequence (16 dots in the next square).
The fourth example is an example of Inductive reasoning because it is based on a pattern or trend of a sequence of events (pre-school, grade 1, grade 2) and uses that pattern to make a prediction or generalization about the next event in the sequence (the child's next teacher will be female).
The fifth example is an example of Deductive reasoning because it starts with a general statement (all football players are muscular) and applies it to a specific case (Peter) to reach a logical conclusion (Peter is a football player). This is the classic form of deductive reasoning, where the conclusion follows logically from the premises and can be proven to be true if the premises are true.

What are congruent triangles?Congruent figures and shapes are those that may be reversed or rearranged such that they match up with other figures and shapes. These shapes can be produced by mirroring these forms.
A closed polygon known as a triangle has three line segments that cross at each of its three angles.
Given two triangles,
ΔHIJ and ΔXYZ
and both are congruent,
ΔHIJ ≅ ΔXYZ
for congruent triangles the measure of sides and angles are equal,
we find that,

Calculate the double integral. ∫∫R 2x/1 + xy dA, R = [0, 2] × [0, 1]
The double integral. ∫∫R 2x/1 + xy dA, R = [0, 2] × [0, 1] is: 2*(1/2ln(3) - 1/2ln(1))
To calculate the double integral ∫∫R 2x/1 + xy dA, we need to integrate with respect to x and y over the region R = [0, 2] × [0, 1].
We can solve this by using the order of integration.
First we need to fix the limits of integration with respect to y and then integrate with respect to x.
∫∫R 2x/1 + xy dA = ∫(0 to 1) (∫(0 to 2) 2x/(1+xy) dx) dy
∫(0 to 1) (∫(0 to 2) 2x/(1+xy) dx) dy = ∫(0 to 1) ( 2*ln(1+xy)|x=0 to 2) dy
∫(0 to 1) ( 2ln(1+2y) - 2ln(1+0) ) dy
= 2*∫(0 to 1) ln(1+2y) dy
= 2*[y*ln(1+2y) - ∫(0 to 1) ln(1+2y) dy] |y = 0 to 1
= 2*[yln(1+2y) - (1/2 ln(3) - 1/2* ln(1))] |y = 0 to 1

What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Given are two linear equations,
y = -x + 4 and
y = 2x - 2
First graph the lines.
For that, find two points on each equation and join them.
For y = -x + 4,x = 0, then y = 4
y = 0, then x = 4
We have two points (0, 4) and (4, 0). Join these points to form the line.
For y = 2x - 2,x = 0, then y = -2
y = 0, then x = 1
We have two points (0, -2) and (1, 0). Join these points to form the line.
We have two equations, which are equal to each other.
-x + 4 = 2x - 2
-x - 2x = -2 - 4
-3x = -6
x = 2
y = -2 + 4 = 2
So the solution of the system of equations is the intersecting point of the two lines which is (2, 2).

If two sides of a triangle are 6cm and 10cm then the lenght of the third side can be
Answer:
6cm
Step-by-step explanation:
Given, the length of two sides of a triangle are 6 cm and 10 cm.
We have to find the length of the third side.
We know that the sum of the lengths of any two sides of a triangle is always greater than the length of the third side.
Sum of two sides = 6 + 10
= 16 cm
We know that the third side must be greater than the difference between two sides and less than the sum of two sides.
Difference of two sides = 10 - 6
= 4 cm
So, the third side must be greater than 4 cm and less than 16 cm.
Therefore, the third side is 6 cm.

This problem can be solved by dividing it into smaller parts.
Let f(x)=ex and g(x)=arctan(x)
The range of the function arctan(ex) is equal to the intersection of the ranges of f(x) and g(x).
Since the range of f(x) is [0,∞] and the range of g(x) is [−π/2,π/2], the intersection is [0,∞] ∩ [−π/2,π/2] or [0,π/2]

An arborist sights the top of a tree using a clinometer and reads the angle of elevation to be 29º, The height of the tree is 17.03 meters
What is the height?Generally, To find the height of the tree, we can use the tangent function and some basic trigonometry. The tangent of an angle is the ratio of the opposite side (the height of the tree) to the adjacent side (the distance from the base of the tree to the clinometer).
tan(29) = opposite / adjacent
We know that the distance from the clinometer to the base of the tree is 28 meters, and that the clinometer is 1.5 meters above ground level.
So we can use the Pythagorean theorem to find the adjacent side:
adjacent = √(28^2 + 1.5^2)
= 28.03 meters
Now we can use the tangent function to find the opposite side:
opposite = tan(29) * adjacent
Using a calculator we can get the opposite = 15.53 meters
The height of the tree is opposite + 1.5 (the clinometer height) '

To perform basic operations, use the basic operation symbols. Addition (+), subtraction (-), multiplication (), and division () are examples of these operations.
Don't be concerned about the order of operations. A scientific calculator will perform calculations in the correct order.
Using the parentheses keys, you can change the order of operations. The calculator's order of operations will be overridden.
Correct your errors. If you accidentally press the wrong key, press the DEL key. This will remove the last button you pressed, but it will not remove any calculations you've made.
Make a clean sweep of your work. To clear the line, press the CLEAR button. You can probably scroll up to see previous calculations. You can delete these by pressing delete after each line.

What value of z should we use when making a 93% confidence interval for p? 1.48 It's impossible to make a 93% CI. 2.70 1.81 To find the z value for a (1-alpha) 100% Cl you need to figure out which z value has alpha/2 area to the right of it. For example, for a 95% CI alpha=1-0.95=0.05, so alpha/2=0.025. If you look up 0.025 in the middle of the Z table it corresponds to z=-1.96. That means the area to the left of z=1.96 is 0.025. So the area to the right of z=1.96 is also 0.025 by symmetry. So the answer would be z=1.96.
1.81 value of z should we use when making a 93% confidence interval for p. This can be solved using the concept of z-table.
What is z-table?The difference from the mean is expressed as a z-score in standard deviation units. It is not clear either one agree or disagree with the null hypothesis. The likelihood that a point as severe as their statistic would be seen that under null hypothesis is known as the p-value.
A z-table, sometimes referred to as the standard normal table, gives the area beneath the curve to the left of a z-score. This region indicates the likelihood that z-values will fall inside a particular area of the standard normal distribution.
At 93% confidence level the z is:
α = 1 - 93%
α = 1 - 0.93
α = 0.07
Now, α /2 = 0.035
Next, Z(α /2) = Z(0.035) = 1.81 ( Using z table )

Kin estimated the distance from his house to his grandmother’s house to be 4.5 miles. The actual distance is 4.32 miles. What is Kin’s percent error? Show your work and/or explain your reasoning.
A-18%
B-0.04%
C-4%
D-0.18%
Answer:
Step-by-step explanation:
To calculate the percent error, we use the formula:
(|(Actual distance - Estimated distance)| / Actual distance) * 100
So for this case:
(|(4.32 - 4.5)| / 4.32) * 100 = (0.18 / 4.32) * 100 = 0.041666666666666664 * 100 = 4.16666667%
Therefore, Kin's percent error is 4.16666667%.
It is important to note that the percent error can be positive or negative depending on whether the estimated value is higher or lower than the actual value.
So the answer is D-0.18%
