Answer:
-4 degrees
Step-by-step explanation:
Starting at 2 degrees, you need to subract 6 since 200 km= 6 degrees and it decreases.
The temperature after 200 km of the polar bear's journey is -4° C.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The daily average temperature decreases 3°C for every 100 km traveled
At the start of the bear's journey, the temperature is 2°C
The total distance traveled by the polar bear = 200 km
For 200 km, [tex](3+3)[/tex] totally 6° C should get decreased.
⇒ [tex](2-6)[/tex]
⇒ [tex]-4[/tex]
Hence we can conclude that the temperature after 200 km of the polar bear's journey is -4° C.

Which relation does not represent a function?
A. {(3, 0), (0, 3)}
B. {(6, -2), (5, -2)}
C. {(3, 4), (3, 5)}
D. {(5, 5), (-5, -5)}
E. {(1, -2), (-2, 1)}
Relation C: {(3,4), (3,5)} does not represent a function because it has the same first component with different outputs.
Explanation:In Mathematics, a relation is defined as a set of ordered pairs. A relation is considered as a function if for each input (x value), there is exactly one output (y value). In other words, no two distinct ordered pairs in the function have the same first component. Looking at the options given:
A. {(3, 0), (0, 3)}B. {(6, -2), (5, -2)}C. {(3, 4), (3, 5)}D. {(5, 5), (-5, -5)}E. {(1, -2), (-2, 1)}The relation C. {(3,4), (3,5)} does not represent a function because there are two distinct ordered pairs with the same first component (or x-value) which is 3, but with two different y-values which are 4 and 5. Therefore, this relation violates the definition of a function.

Final answer:
The relation that does not represent a function is Option C: {(3, 4), (3, 5)} because the number 3 in the domain is paired with two different values in the range, contradicting the definition of a function.
Explanation:
The relation that does not represent a function is Option C: {(3, 4), (3, 5)}. This is because a function is defined as a set of ordered pairs where each element of the domain (the first value in each pair) must correspond to exactly one element in the range (the second value in each pair). Option C depicts the number 3 in the domain being paired with both 4 and 5 in the range, which violates this rule. Therefore, Option C does not satisfy the definition of a function.
Option A, B, D, and E each show that every element of the domain is matched with only one unique value in the range, indicating they are all functions.
Based on the data set shown, which of the following is a true statement?
-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
mean = mode
mean < median
mode < median
Answer:
mean = mode
Step-by-step explanation:
To make this easier, let's find the mean, median, and mode.
Mean: Sum of a set of numbers divided by number of terms
Median: Middle number of data when data is in numerical order
Mode: Number that occurs most often in data
To find the mean, add all the values together. -1 - 1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 = 11. Now, divide by the number of terms, which is 11. 11/11 = 1. The mean is 1.
To find the median, look at the number in the middle of the data. -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3. The median is 1.
To find the mode, look at the number that occurs most often. There are 4 1's, so the mode is 1.
Since all numbers are equal, the only possible answer is the first option.
The mean, median, and mode are all equal; thus, a.) mean = mode is true.
Sum of all values: (-1) + (-1) + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 = 11
Number of values: 11
Mean = Total sum / Number of values = 11 / 11 = 1
Arrange the values in ascending order: -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
The middle value (6th value) is 1
Median = 1
The value that appears most frequently is 1 (occurs 4 times)
Mode = 1
Comparing these values:
Mean = 1
Median = 1
Mode = 1

Step-by-step explanation:
The first side of a triangle measures 5 in. less than the second side, the third side is 3 in, more than the first side, and the
perimeter is 17 in. How long is the third side?
If s represents the length of the second side, which of the following represents the length of the third side?
A. s - 5
B. s-2
C. s+3
Final answer:
The third side of the triangle is determined by the expression 's - 2 inches', where s represents the length of the second side of the triangle.
Explanation:
To find the length of the third side of the triangle, we can first define the lengths of the other two sides in terms of s, the length of the second side. The first side is s - 5 inches, according to the problem statement. Since the third side is 3 inches more than the first side, its length would be (s - 5) + 3, which simplifies to s - 2 inches.
Now, knowing that the perimeter of the triangle is 17 inches, we can set up an equation to include all three sides: s + (s - 5) + (s - 2) = 17 inches. Solving this equation for s will give us the length of the second side and consequently the length of the third side using s - 2 inches.

In isosceles △ABC with AC = AB, points D ∈ AB and E ∈ AC so that DB = EC. Point P is the intersection point of DC and EB, m∠ADC = 107°, m∠ABE = 45°. Find m∠BAP.
Please show work.
9514 1404 393
Answer:
14°
Step-by-step explanation:
∠ADP is an external angle to ΔDBP, so ...
∠ADP = ∠DBP + ∠DPB
107° = 45° + ∠DPB
∠DPB = 107° -45° = 62°
∠DPB is an external angle to isosceles triangle PBC, so ...
∠DPB = 2×∠PBC
62° = 2×∠PBC
∠PBC = 62°/2 = 31°
Of course, the angle sum theorem applies at vertex B, so ...
∠ABC = ∠ABP +∠PBC
∠ABC = 45° +31° = 76°
AP is the angle bisector of angle A, so, if extended to BC would be perpendicular to BC. Then ∠BAP is complementary to ∠ABC:
∠BAP = 90° -∠ABC
∠BAP = 90° -76°
∠BAP = 14°
Final answer:
m∠BAP = 124°
Explanation:
Given that △ABC is an isosceles triangle with AC = AB and DB = EC, we can conclude that △ADC and △AEB are congruent triangles by the Side-Angle-Side (SAS) congruence theorem. Therefore, m∠ADC = m∠AEB. Since m∠ADC = 107° and m∠AEB = 45°, we can write:
m∠ADC = m∠AEB
107° = 45° + m∠ABD
m∠ABD = 107° - 45°
m∠ABD = 62°
Since △ABD is isosceles with AB = AD, we have m∠ABD = m∠ADB. Therefore, m∠ADB = 62°. Since m∠BAP is an exterior angle of △ABD, we can apply the Exterior Angle Theorem to find:
m∠BAP = m∠ADB + m∠ABD
m∠BAP = 62° + 62°
m∠BAP = 124°

Which of the following theorems verifies that DEF - XZY?
Answer:
AA
Step-by-step explanation:
The question is about the congruency of two triangles DEF and XZY. A Congruence Theorem (SSS, SAS, ASA, or AAS) would demonstrate their congruence, but without specific measurements, we can't identify which theorem applies.
Explanation:The subject area of this question is Geometry, more specifically, the concepts concerning triangles. The given notation, DEF - XZY, suggests that the student wants to establish the congruency between the two triangles DEF and XZY.
Based on the information provided, the student is likely referring to a Congruence Theorem, which is one of the primary methods to determine if two given triangles are congruent. The main Congruence Theorems are: SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), and AAS (Angle-Angle-Side).
Without any additional specification, it's impossible to definitively say which theorem supports DEF - XZY. The student would need to provide specific measurements related to the triangles DEF and XZY, such as the lengths of the sides or the measures of the angles, to determine which Congruence Theorem applies.

a ≤ 20 and a ≥ 25
Answer:
ok so for a ≤ 20 it is A is less than or equal to 20
a ≥ 25 is A is greater than or equal to 25
Step-by-step explanation:
whenever you have a symbol like ≥, where it has a line under it, it means it could be equal to. And when the symbol is like a<20 (where < is the alligator it eats the bigger number so 20 is larger) And this means a is less than but since there is ≥ then its Equal to as well. :) sorry if this is confusing i will be willing to further explain if needed.

Based on the dimensions in the diagram, what is the value of x?
The value of ∠x is 30⁰. Option B is correct.
How to determine the ratio value of ∠x in the figure.
From the given figure,
The triangle formed by ladder is right angled triangle
∠x⁰ is opposite to the horizontal distance between the foot of the and the point where the ladder touches the ground.
The ladder form the hypotenuse of the triangle.
Therefore,
sinθ = opposite/hypotenuse
θ is the angle opposite to distance between the wall foot and the ladder.
θ = x⁰
opposite = 10 ft
hypotenuse = 20 ft
so,
Sin(x) = 10/20
sin(x) = 1/2
find the sine inverse of (0.5)
x = sin⁻¹(0.5)
x = 30⁰
The value of ∠x is 30⁰. Option B is correct.

Albert is building a table and 4 chairs. He will use 18 nails to build each chair and 42 nails to
build the table. He estimates that he will need roughly 180 nails. Does that sound about
right?
Yes.
No, it is much too high,
No it is much to low
Albert's estimate of 180 nails is much too high since the actual calculation shows that he only needs 114 nails for the table and four chairs.
Explanation:To determine if Albert's estimate of needing roughly 180 nails for building a table and 4 chairs is correct, we should calculate the total number of nails required for this project. For each chair, he will need 18 nails, and for the table, he will need 42 nails.
Therefore, the total number of nails needed for the chairs is:
18 nails/chair × 4 chairs = 72 nailsAnd the number of nails needed for the table is:
42 nailsAdding these together gives us:
72 nails + 42 nails = 114 nailsComparing this with Albert's estimate of 180 nails, we can see that his estimate is much too high.
