Walter wants to learn more about the preferred salad ingredients of students in his
school. He surveys all students in his math class and finds that 4 prefer tomatoes,
14 prefer carrots, and 9 prefer cucumbers. What is the population and sample? Is
the sample a representative sample? Explain.
For example , If we want to calculate the average income of American data scientist , all American data scientists will be determine the population in this case,
A sample denotes a subset of population . When population is extremely large , the researcher draw a sample of the entire population and use this to analysis and study. So we can say a sample can represent a particular population.Here, Walter surveys all students in his math class and finds that 4 prefer tomatoes, 14 prefer carrots, and 9 prefer cucumbers.
Population = All students in his School
Sample = Students in his class.
No, the sample is not a representative sample, it is the convenience sample.
It can be possible that his class has influence of him or students of other classes may like exactly different ingredients for salad like sprouts, fruit etc.

Step-by-step explanation:
5. sin 31 = opp/ hyp
sin 31 = 34 /x
x = 34 / sin 31
x =66.0145369
tan 31 = opp /adj
tan 31 = 34/y
y = 34/ tan 31
y= 56.5855024
6. Pythagorean theorem to find z
9^2+12^2 = z^2
81+144 = z^2
225 = z^2
z =sqrt(225) =15
sin x = opp / hyp
sin x = 9/15
take the inverse sin
x = sin^ -1 (9/15) = 36.86989765
sin y = opp / hyp
sin y = 12/15
take the inverse sin
y = sin^ -1 (12/15) = 53.13010235
Answer:
1. sin(31) = opposite/hypotenuse
sin(31) = 34/x
x = 34/sin(31) = 66.0145369
x = 66.0°
tan(31) = opposite/adjacent
tan(31) = 34/y
y = 34/tan(31) = 56.5855024
y = 56.6°
2. tan(x) = opposite/adjacent
tan(x) = 9/12
x = 36.86989765
x = 36.9°
y = 180 - 90 - x
y = 53.13010235
y = 53.1°
z² = 9² + 12²
z² = 225
z = 15
If Logan's family can drive 23 1/8 miles on 1 gallon of gas, how far can they drive on 17 gallons?
Answer:
393 1/8 miles
Step-by-step explanation:
Distance driven in 1 gallon of gas = 23 1/8 miles
23 1/8 miles is mixed fraction.
converting 23 1/8 into improper fraction
23 1/8 = (23*8 + 1)/8 = 185/8
Thus 1 gallon of gas can drive 185/8 miles. ____________1
Since distance for 17 gallons is needed.
we multiply both gallon of gas and distance with 17.
1 *17 gallon of gas can drive 185/8*17 miles
17 gallon of gas can drive (185/8)*17 miles
=>17 gallon of gas can drive (3,145)/8 miles
converting (3,145)/8 miles into mixed fraction we have 393 1/8 .
Thus, Logan's family can drive 393 1/8 miles on 17 gallons.

B) 42 signifies the hourly rate, and 32 signifies the overhead charge
C) 74 signifies the cost for an on-site inspection
D) -42 signifies the hourly rate, and 32 signifies the travel cost
Answer:
B) 42 signifies the hourly rate, and 32 signifies the overhead charge
Step-by-step explanation:
The hourly rate is the amount of money given per hour worked. 42x basically means that for every hour, $42 are given.
As for 32, it is the overhead charge, which isn't paid every hour but rather only once. That is why it has no variable beside it.

find the area of the triangle whose vertices are x(3,2) y(-1,0)and z(1,-12)
Answer:
The triangle whose vertices are x(3,2) y(-1,0)and z(1,-12).
=> xy = sqrt(4^2 + 2^2) = 4.472
=> xz = sqrt(2^2 + 14^2) = 14.142
=> yz = sqrt(2^2 + 12^2) = 12.166
=> Perimeter/2 = P = (xy + yz + xz)/2 = (4.472 + 14.142 + 12.166)/2 = 15.39
=> Applying Heron's formula, the area of triangle would be:
A = sqrt(P*(P-xy)*(P-xz)*(P-yz))
= sqrt(15.39*(15.39 - 4.472)*(15.39 - 14.142 )*(15.39 - 12.166))
= 26.001
= ~26

Could the baton lie flat on a diagonal along the base of the box?
A. Yes, because the diagonal is 48 inches long.
B. Yes, because the diagonal is 41.4 inches long.
C. No, because the diagonal is 37.3 inches long.
D. No, because the diagonal is 18.4 inches long.
I think C. but need help, is it right? How so?
Part B
Could the baton fit along the interior diagonal of the box? Explain.
Answer:
C.; Yes
Step-by-step explanation:
A)
The longest thing that can fit along the base of the box is sqrt ( 13^2 + 35^2) = 37.3, which is less than 38, so NO, the baton can't lay flat on a diagonal along the base of the box C. No, because the diagonal is 37.3 inches long.
B) The interior diagonal of the box is sqrt(13^2 + 13^2 + 35^2) = sqrt (1563), which is 39.5, which is greater than 38, so YES, the baton can fit along the interior diagonal of the box.

Which of the following represents the symmetric property of congruence?
Question 3 options:
A)
If ≅ , then ≅
B)
If ≅ , then ≅
C)
≅
D)
If ≅ and ≅ , then ≅
Answer:
The symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, AB ≅ CB, then CB ≅ AB.
Step-by-step explanation:
Two triangles are said to be congruent if they have the same three sides and the same three angles, not necessarily the same sides or the same angles are equal.
The properties of congruence are:
Reflexive property:
For all angles A, ∠A ≅ ∠A. That is, all angles are congruent to themselves.
If AB is side of a triangle then, AB ≅ AB.
Symmetric Property:
For any angles A and B if, ∠A ≅ ∠B, then ∠B ≅ ∠A.
For sides AB and CB of a triangle if, AB ≅ CB, then CB ≅ AB.
Transitive property:
For any angles A, B and C if, ∠A ≅ ∠B, and ∠B ≅ ∠C then ∠A ≅ ∠C.
For sides AB, CB and CA of a triangle if, AB ≅ CB, and CB ≅ CA, then AB ≅ CA.
Thus, the symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, AB ≅ CB, then CB ≅ AB.
Final answer:
The symmetric property of congruence is represented by Option B: If AB ≡ CD, then CD ≡ AB, aligning with the principle that if one quantity equals another, the second equals the first as well.
Explanation:
The symmetric property of congruence states that if one geometric figure is congruent to another, then the second is also congruent to the first. This is a reflection of the more general symmetric property of equality in algebra, which states that if one quantity equals another, the second equals the first as well.
Looking at the provided options, the one that represents the symmetric property of congruence is:
Option B: If AB ≡ CD, then CD ≡ AB.
This option correctly reflects the symmetric property, which can be written as if p ≡ q, then q ≡ p where p and q are geometric figures or algebraic expressions.

Answer:
2,5
Step-by-step explanation:
2,5 is just one of the many solutions to this problem. you can just take a random number for x, for example 2. your equation will look like this 3(2)-y=1. now you just solve for y. 3x2=6. 6-1=5. so y=5.
To find the solution to the equation 3x - y = 1, we can choose a value for x and solve for y. By substituting x = 2, we find that the ordered pair (x, y) = (2, 5) is a solution.
Explanation:To find an ordered pair (x, y) that is a solution to the equation 3x - y = 1, we first need to choose a value for x and then solve for y. Let's choose x = 2:
Substitute x = 2 into the equation: 3(2) - y = 1Simplify: 6 - y = 1Isolate y by subtracting 6 from both sides: -y = 1 - 6Simplify: -y = -5Divide by -1 to solve for y: y = 5

How many 5-letter “words” can be formed from the letters of the word FORMULATED, if each will have the vowels at the two ends on the “word”?
Final answer:
To calculate the number of 5-letter "words" with vowels on the ends from 'FORMULATED', you multiply the number of ways to choose the two vowels (4 x 3) by the number of ways to choose the three different consonants (6P3; 6 x 5 x 4), resulting in 1440 different possible "words."
Explanation:
To determine the number of 5-letter "words" that can be formed from the letters of the word FORMULATED with vowels at both ends, we need to consider two parts: the selection of vowels and the selection of consonants. The word FORMULATED contains four vowels (O, U, A, E) and six consonants (F, R, M, L, T, D).
First, we choose the vowels for the ends. There are 4 vowels, which means we can select the first vowel in 4 ways. After selecting the first vowel, we can still choose the second vowel from the remaining 3 vowels (since we are allowing repetitions). This gives us 4 x 3 possibilities for the vowels.
Now we select the consonants for the center three positions. We have 6 different consonants to choose from, and since each position must be filled with a unique letter, we can select these in 6P3 (6 permute 3) ways, which is calculated as 6 x 5 x 4.
Finally, to find the total number of 5-letter "words," we multiply the number of ways to choose the vowels by the number of ways to choose the consonants, giving us 4 x 3 x 6 x 5 x 4 which equals 1440 possible "words."
