Write an equation that has constant of proportionality between those represented on the graph
Using proportional relationships, we have that:
a) They are defined as follows:
Soprano = 0.1 x Students.Trucks = 1/3 x Vehicles.b) The relation is Out of State Team = 1/5 x Residents.
Proportional relationships and graphsA graph represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:
y = kx.
Voice instructor notices that only one out of every ten of her students can sing soprano, hence the constant is:
k = 1/10 = 0.1.
Then the relationship is:
Soprano = 0.1 x Students.
Two out of every six vehicles are trucks, hence the constant is:
k = 2/6 = 1/3.
Hence the relationship is:
Trucks = 1/3 x Vehicles.
Then, in item b, we want to write a relation that has a constant between those represented on the previous relations, that is, between 1/10 and 1/3.
One possible constant is of 1/5. Supposing that one out of five New York City residents root for out of state NFL teams, the relation is:

4. 3 ✖️ 5 + 4 - 2 ✖️ 2 + 6 - 4 = 15
The equations with parentheses added to make them true are;
(4 × (3 + 7 - 6) × 1) + 4 = 20(60 - 18) ÷ (2 + 4) + 10÷2 = 1280 - 36 ÷ (2 + 6 - 2) × (5 + 1) = 443 × (5 + 4) - (2 × (2 + 6) - 4) = 15What is the effect of parentheses in a mathematical expression?Parentheses indicate that operations within it should be completed first before those that are outside the parentheses.
The given terms of the equations can be regrouped with parentheses to make the equations true as follows;
1. 4 × 3 + 7 - 6 × 1 + 4 = 20
The above equation gives;
3 + 7 - 6 = 4
Therefore;
4 × 3 + 7 - 6 × 1 + 4 = 4 × (3 + 7 - 6) × 1 + 4
4 × (3 + 7 - 6) × 1 + 4 = (4 × 4) × 1 + 4
(4 × 4) × 1 + 4 = 16 × 1 + 4 = 16 + 4 = 20
Which gives;
(4 × (3 + 7 - 6) × 1) + 4 = 202. 60 - 18 ÷ 2 + 4 + 10 ÷ 2 = 12
60 - 18 = 42
2 + 4 = 6
The first four terms, therefore gives;
(60 - 18) ÷ (2 + 4) = 7
10÷2 = 5
Which gives;
60 - 18 ÷ 2 + 4 + 10 ÷ 2 = (60 - 18) ÷ (2 + 4) + 10÷2
(60 - 18) ÷ (2 + 4) + (10÷2) = 7 + 5 = 12
Which gives;
60 - 18 ÷ 2 + 4 + 10 ÷ 2 = (60 - 18) ÷ (2 + 4) + 10÷2 = 12
The expression is therefore;
(60 - 18) ÷ (2 + 4) + 10÷2 = 123. 80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 44
80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 80 - 36 ÷ (2 + 6 - 2) × (5 + 1)
(2 + 6 - 2) = 6, and (5 + 1) = 6
Therefore;
80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 80 - ((36 ÷ 6) × 6)
80 - ((36 ÷ 6) × 6) = 80 - ((36 × 6) ÷ 6)
80 - ((36 × 6) ÷ 6) = 80 - (36 × 1) = 44
Therefore;
80 - 36 ÷ (2 + 6 - 2) × (5 + 1) = 444. 3 × 5 + 4 - 2 × 2 + 6 - 4 = 15
3 × 5 + 4 - 2 × 2 + 6 - 4 = 3 × (5 + 4) - (2 × (2 + 6) - 4)

You are making extra part kits for a game. The table below lists the number of each part needed per kit, as well as the number of each part that you have available.
Part Number in each kit Number available
People marker 6 287

Teleporter marker 7 341
You make as many kits as you can. With the parts remaining, you could make 1 more kit if you had:
A.1 more people marker and 1 more die.
B.1 more die and 1 more teleporter marker.
C.1 more teleporter marker and 1 more people marker.
D.2 more people markers.
E.2 more teleporter markers.
Applying mathematical operations with the remaining parts, you could have 1 more kit if you had A.1 more marker and 1 more die.
How is the number determined?Using mathematical operations of divisions, subtractions, and additions, we can determine the number of kits made from the materials and the part required to make one additional kit.
For instance, 287 people marker can make 47 (287/6) kits with 5 remaining, which requires another 1 part to complete another kit.
143 6-sided die can also make 47 kits (143/3) with 2 parts, which require an additional 1 part to make another kit.
The above parts are unlike the teleporter marker, which had already made 48 kits with 5 of its part remaining.
Part Number in each kit Number available # of Kits Made
People marker 6 287 47
6-sided die 3 143 47
Teleporter marker 7 341 48
Thus, using mathematical operations, we can determine that to complete the number of kits to 48, the kit maker requires Option A.

The parameters are ΔUVW with side UW extended to X then m ∠UVW = (3x + 4)°, m ∠VWX = (8x -12)° and m ∠WUV = (x + 20)° then the value of x = 9°.
How to estimate the value of x?The given parameters exist;
ΔUVW with side UW extended to X
m ∠UVW = (3x + 4)°, m ∠VWX = (8x -12)° and m ∠WUV = (x + 20)°
We have that m ∠UVW + m ∠WUV + m ∠VWU = 180° (Sum of the interior angles of a triangle theorem)
Therefore, m ∠VWU = 180° - (m ∠UVW + m ∠WUV)
Also, we have that m ∠VWX and m ∠VWU exist supplementary angles, (The sum of angles on a straight line)
∴ m ∠VWX + m ∠VWU = 180° (Definition of supplementary angles)
m ∠VWU = 180° - m ∠VWX
∴ m ∠VWX = (m ∠UVW + m ∠WUV)
Substituting the values in the above equation, we get;
(8x -12)° = (3x + 4)° + (x + 20)°
simplifying the above equation, we get
8x - 3x - x = 4 + 20 + 12
4x = 36
x = 36/4 = 9
Therefore, the value of x = 9°.

In how many ways can four women be chosen from the group of 7 women?
What is the probability that all women will be chosen to attend the conference?
Enter a reduced fraction or decimal.
In 1820 different ways a group of four people can be selected from this group of 16.
In 35 ways four women can be chosen from the group of 7 women.
The probability that all women will be chosen to attend the conference is 1.92%.
What is probability?The proportion of favourable outcomes to all possible outcomes of an event is known as the probability. The number of positive outcomes for an experiment with 'n' possible outcomes can be represented by the symbol x. The probability of an event can be determined using the following formula.
To find how many different ways can a group of four people be selected from this group of 16, we will implement the combination formula.
[tex]^n C_r=\frac{n !}{r ! (n-r) !}[/tex]
Where,
nCr = number of combinations
n = total number of objects in the set
r = number of choosing objects from the set
Here, n = 16 and r = 4, substituting the values we get
[tex]^{16} C_4=\frac{16 !}{4 ! (16-4) !}[/tex]
[tex]^{16} C_4 =[/tex] 1820
Hence, in 1820 different ways a group of four people can be selected from this group of 16.
To find how many ways can four women be chosen from the group of 7 women we will implement the combination formula.
Here, n = 7 women and r = 4 women, substituting the values we get
[tex]^7 C_4=\frac{7 !}{4 ! (7-4) !}[/tex]
[tex]^7 C_4=[/tex] 35
Thus, in 35 ways four women can be chosen from the group of 7 women.
The probability that all women will be chosen to attend the conference is
[tex]\frac{^7 C_4}{^{16}C_4}[/tex] = 35/1820

The price of an adult ticket and a student ticket is $14 and $8, respectively.
Using algebraic expression and equation, we can express each statement and determine the price of each ticket.
Let x = the price of an adult ticket
y = the price of a student ticket
If on the first day of ticket sales, the school sold 3 student tickets and 1 adult ticket for a total of $38, then we can express this as:
3y + x = 38 (equation 1)
If the school took in $52 on the second day by selling 3 student tickets and 2 adult tickets, then we can express this as:
3y + 2x = 52 (equation 2)
3y + 2x = 52 (equation 2)
-(3y + x = 38) (equation 1)
x = 14
Substitute the value of x in any of the two equations.
3y + x = 38 (equation 1)
3y + 14 = 38

The answers to all the subparts are given below:
(A) Minimum percentage of commuters in the city: 0.75(B) Minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean: [16.65, 37.95](C) Minimum percentage of commuters who have commute times between 6 minutes and 48.6 minutes: 89%What is the percentage?A percentage is a number or ratio expressed as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent sign, "%," is frequently used to indicate it. A percentage is a number without dimensions and without a standard measurement. By dividing the value by the total value and multiplying the result by 100, one can determine the percentage. The percentage calculation formula is (value/total value)×100%.So, (A) Chebyshev's theorem is used:
There can only be 1/k2 values of a distribution.k deviations from the mean are used.Here k = 2So,
1/k² = 1/2² = 1/4 = 0.25Therefore, the minimum proportion of commuters who are within two standard deviations of the mean is:
1 - 0.25 = 0.75 m(B) Minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean:
Here, k = 1.5
1/k² = 1/1.5² = 1/2.25 = 0.444Consequently, the shortest commute within two standard deviations of the mean is:
1 - 0.444 = 0.56 = 56%Within 1.5 standard deviations, commute times:
[27.3 - (1.5 × 7.1), 27.3 + (1.5 * 7.1)[16.65, 37.95](C) Minimum percentage of commuters who have commute times between 6 minutes and 48.6 minutes:
X - m /sdX = 6= (6 - 27.3) / 7.1 = - 3X = 48.6= (48.6 - 27.3) / 7. 1 = 3So,
1/k² = 1 / 3² = 1/91 - 1/9 = 8/9= 0.888 = 0.89 = 89%Therefore, the answer to all the subparts are given below:
(A) Minimum percentage of commuters in the city: 0.75(B) Minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean: [16.65, 37.95](C) Minimum percentage of commuters who have commute times between 6 minutes and 48.6 minutes: 89%Know more about percentages here:
