Step-by-step explanation:
You want a Venn diagram that represents the flavor preferences of 135 students.
Venn DiagramThe diagram you show is a good start. It usually works best to start by filling in the center spot, where all three circles overlap. You have correctly identified the number liking all three flavors as 15.
Working outward, the next step is to fill in the numbers for those who like two flavors. These numbers already include the number who like all three. This means ...
caramel + vanilla (only) = (caramel + vanilla) (28) - (caramel +vanilla +chocolate (15)
caramel + vanilla (only) = 28 -15 = 13
Similar computations are done for the other "likes 2 only" spots on the diagram:
chocolate + caramel (only) = 31 -15 = 16
chocolate + vanilla (only) = 22 -15 = 7
In like fashion, the numbers for one flavor only need to subtract out the numbers already inside the circle for that flavor.
chocolate (only) = 63 -16 -15 -7 = 25
Finally, the number of students having no preference is found by subtracting the numbers inside the parts of the circles from the total number of students:
no preference = 135 -111 = 24
The attachment shows the completed diagram.

Based on the information, we can infer that the salary a worker earns depends on the hourly wage they earn. In this case we will have to multiply the value of each hour by the number of hours worked. Additionally, I would agree to have a higher minimum wage to benefit workers.
What salary will workers have in each salary?Based on the information in the graph, we can infer that workers will have wages of $5.2, $6.0, and $6.6. According to the above, the salary varies depending on the number of hours.
On the other hand, I believe that you would agree to a salary increase because this would benefit workers who would be better paid for each hour of work.

What is the sine of 0?
(Need help)
The angle of sinθ between the horizontal vector (1, 0) and the slant vector (15/17, -8/17) is sin⁻¹(8/17), which is approximately 29.11 degrees.
To find the angle of sinθ between a horizontal vector and a slant vector, we can use the dot product formula:
a · b = |a| |b| cos(θ)
where a and b are vectors, |a| and |b| are their magnitudes, and theta is the angle between them.
In this case, the horizontal vector is (1, 0) and the slant vector is (15/17, -8/17).
The magnitude of the horizontal vector is 1, and the magnitude of the slant vector is:
|b| = sqrt((15/17)² + (-8/17)²) = sqrt(225/289 + 64/289) = sqrt(289/289) = 1
The dot product of the two vectors is:
a · b = (1)(15/17) + (0)(-8/17) = 15/17
So we have:
15/17 = (1)(1) cos(θ)
cos(θ) = 15/17
To find sin(θ), we can use the trigonometric identity:
sin²(θ) + cos²(θ) = 1
sin²(θ) = 1 - cos²(θ) = 1 - (15/17)² = 64/289
Taking the square root of both sides, we get:
sin(theta) = sqrt(64/289) = 8/17

The given equation solved for w is w = t + x - v
Solving Linear equationsFrom the question, we are to solve for w in the give equation
The given equation is
v + w - x = t
To solve for w in the given equation, we will make w the subject of the equation
Solving the equation
v + w - x = t
Add x to both sides of the equation
v + w - x + x = t + x
v + w = t + x
Now, subtract v from both sides of the equation
v - v + w = t + x - v
w = t + x - v

Step-by-step explanation:
The original ration is 2 gallons of water for 4 players.
Each player requires 1/2 gallon of water.
To get the amount of water needed multiply 1/2 by the amount of players.

2*(1/2) equals 1
10*(1/2) does not equal 4
30*(1/2) equals 15
Identify any angles of rotation that create symmetry
The angle of rotation that create symmetry in the image is 120°.
We are given an image.
We need to find the angles of rotation that creates this symmetry.
We know that the whole plane is divided into 12 parts.
That is 360° is divided into 12 parts.
So, we get that:
1 part = 360° / 12 = 30°
Now, we can also see that, from rotation to one quadrant to another, the image travels 4 parts of the plane.
So, angle of rotation will be = 4 × 30°
angle of rotation = 120°
Therefore, we get that, the angle of rotation that create symmetry in the image is 120°.

Answer:
b. $154,810
Step-by-step explanation:
You want to know the price of a home that can be purchased for a monthly payment of $879.32 on a 30-year loan at 5.5%.
TableThe given table tells you the multiplier m used to find the monthly payment p from the loan amount P for different time periods and interest rates.
p = (P/1000)×m
ApplicationThe table value for a 30-year loan at 5.5% is m = 5.68. Solving the equation for P, we have ...
1000p/m = P
1000(879.32/5.68) = P ≈ 154,809.86 ≈ 154810
You qualify for a loan of $154,810.

Additional comment
The multiplier 5.68 is found on row 2 (5.5%) of column 4 (30 years).
By answering the presented question, we may conclude that As a result, equation the answer is (b) $154,810.
What is equation?A mathematical equation is a formula that connects two statements and denotes equivalence with the equals symbol (=). An equation is a mathematical statement that shows the equality of two mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the variables 3x + 5 and 14. A mathematical formula describes the connection between the two sentences that occur on opposite sides of a letter. The symbol and the single variable are frequently the same. As in 2x - 4 Equals 2, for instance.
To establish the purchase price of a property, we must use the monthly payment and the table supplied to determine the mortgage amount that corresponds to the monthly payment.
According to the data, the monthly payment per $1000 of mortgage for a 30-year fixed mortgage at a 5.5% interest rate is $5.68.
Hence, to calculate the mortgage amount for a $879.32 monthly payment, we may apply the following formula:
Mortgage amount = monthly payment / mortgage payment per $1000
$879.32 mortgage amount / $5.68 per $1000
Loan amount = $154,810
As a result, the purchasing price of a house is $154,810.
As a result, the answer is (b) $154,810.

The daily fee is $34 and the mileage charge is $0.19 per mile.
How to calculate daily fee and mileage charge?Let's start by using variables to represent the daily fee and the mileage charge. Let's say the daily fee is "d" (in dollars per day) and the mileage charge is "m" (in dollars per mile).
From the information given, we can set up two equations:
For the first trip:
4d + 450m = 221.5 (equation 1)
For the second trip:
3d + 200m = 140 (equation 2)
We want to find the values of d and m that satisfy both equations.
Let's rearrange equation 1 to solve for d in terms of m:
4d = 221.5 - 450m
d = (221.5 - 450m)/4
Now we can substitute this expression for d into equation 2:
3[(221.5 - 450m)/4] + 200m = 140
Simplifying this equation gives:
166.125 - 337.5m + 200m = 140
-137.5m = -26.125
m = 0.19
So the mileage charge is $0.19 per mile.
To find the daily fee, we can substitute this value of m back into either equation 1 or 2 and solve for d. Let's use equation 1:
4d + 450(0.19) = 221.5
4d + 85.5 = 221.5
4d = 136
d = 34
So the daily fee is $34 per day.
Therefore, the daily fee is $34 and the mileage charge is $0.19 per mile.
