1. A percent is found by dividing the percentage by the base. True
or false

Answers

Answer 1

It is true but incomplete, a percent is found by dividing the percentage by the base and multiplying it with 100.

What is percentage?

Percentage is a relative value that represents hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

Divide the percentage by the quantity to get the percent of a number, then multiply the result by 100. Put the word "percent" (%) after the finished item.

Example of calculation of percentage:

What percent of 10 is 7?

here, 7 is percentage and 10 is quantity, On dividing we get,

7/10 = 0.7

Now multiplying by 100, we get

70 %

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 = 2

So,

1/k² = 1/2² = 1/4 = 0.25

Therefore, 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 = 0.444

Consequently, 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 = 3

So,

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%

given h(x)=4x+4,find h (2)

Answers

The output value of h( 2 ) in the function h( x ) = 4x + 4 is 12.

What is the output value of h(2) in the given function?

A function is a relationship that maps one input to one output, for a relation to qualify as a function, each of its x-value can only have one y-value.

Given the data in the question;

h( x ) = 4x + 4h( 2 ) = ?

To solve for the output value of h( 2 ), replace all the occurrence of x with 2 in the function and simplify.

h( x ) = 4x + 4

h( 2 ) = 4( 2 ) + 4

Multiply 4 and 2

h( 2 ) = 8 + 4

Add 8 and 4

h( 2 ) = 12

Therefore, the output value is 12, this forms an ordered pair of (2,12) on the graph.

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.

Answers

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

       = 0.01923076

       = 1.92%

Thus, the probability that all women will be chosen to attend the conference is 1.92%.

What 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 = 20

2. 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 = 12

3. 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) = 44

4. 3 × 5 + 4 - 2 × 2 + 6 - 4 = 15

3 × 5 + 4 - 2 × 2 + 6 - 4 = 3 × (5 + 4) - (2 × (2 + 6) - 4)

Answer:

x = 27

Step-by-step explanation:

AOB is a straight angle = 180°

the 3 angles on it therefore sum to 180° , that is

36 + 90 + 2x = 180

126 + 2x = 180 ( subtract 126 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

carnegie vanguard is selling tickets to a theatre performance. on the first day of ticket sales the school sold 3 student tickets and 1 adult ticket for a total of $38. the school took in $52 on the second day by selling 3 student tickets and 2 adult tickets. find the price of an adult ticket and the price of a student ticket

Answers

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

3y = 38 - 14

3y = 24

y = 8

price of an adult ticket = $14

price of a student ticket = $8

Write an equation that has constant of proportionality between those represented on the graph

Answers

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 graphs

A 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:

Out of State Team = 1/5 x Residents.

A cave explorer is at an elevation of −32 feet. The explorer starts moving at a rate of −6 feet per minute. Write and solve an inequality that represents how long it will take, $t$ (in minutes), the explorer to reach an elevation deeper than −140 feet.

Answers

If a cave explorer is at an elevation of −32 feet and the explorer starts moving at a rate of −6 feet per minute. it will take, 9 in minutes for the explorer to reach an elevation deeper than −140 feet.

Time

Elevation of feet =  −32 feet.

Feet per minute =  −6 feet per minute

Elevation deeper than  feet = −140 feet

Let x  represent the time for reach the desired height

Inequality

-32 - 6x = ≤ -140

Substract 32 from both side

12x ≤ 140 -32

12x  ≤ 108

Divide both side by 12x

x ≤ 108/12

x ≤ 9

Therefore we can conclude that the explorer will have to use 9 minutes to get to the elevation.

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°.

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
6-sided die 3 143
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.

Answers

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.
