  The proportion of the sample obtained from the survey is 0.055

 The percentage is a mathematical operation that is expressed with the symbol "%" is a relationship that allows us to know the portion of an initial value to represent a set.

  It could also be defined as a representation of an original value that lets us know a certain number of elements that we want from that original value or set.

 To solve this problem, we use a simple rule of three to find the percentage value of the sample.

289 -------- 100%

273 ---------  x

x = (273 * 100%) / 289

x = 94.46%

100% - 94.46% = 5.53%

The ratio in propotion with 3 decimals is

5.53/100  = 0.055

Average cost of a gallon of gas in Texas in 2013 was $3.42.

Given,

Average cost of a gallon of gas in Texas in 2010 = $2.53

From 2010 to 2013 average cost of regular gasoline in Texas increased by 35%

We have to find the average cost of a gallon of gas in Texas in 2013:

= Average cost in 2010 × (135/100)

= 2.53 × (135/100)

= 2.53 × 1.35

= 3.4155

≈ 3.42

That is, the average cost of a gallon of gas in Texas in 2013 was $3.42 approximately.

The actual distance between Yappy city and Quiet city when it is 23 cm in map is 9.2 miles.

What is scaling ?

It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.

It is given that :

The distance on the map between Yappy city and Quiet city is 23 cm

and,

5cm = 2 miles

now, for 1 cm on map it is equal to 2/5 miles of actual distance.

Therefore to find the actual distance of 23 cm in map we simply multiply 23 with 2/5 :

actual distance :

2/5 x 23 = 9.2 miles

Therefore, the actual distance between Yappy city and Quiet city is 9.2 miles.

The third term of a given geometric sequence based on common ratio 2 is 8.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

Given a geometric sequence.

First term = 2

Second term = 4

Common ratio = Next term / previous term

Common ratio = 4/2 = 2

So,

Common ratio = Third term / second term

The third term = common ratio × second term

The third b = 2 × 4 = 8

Hence "The third term of a given geometric sequence based on common ratio 2 is 8".

Total amount of money in the account in the second bank after 3 years will be represented by the function: P[tex]e^{0.0747}[/tex].

The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-

A = P[tex]e^{rt}[/tex]

Here, we are given that there are 2 financial institutions-

1st financial institution:

interest rate =  3% for the first year

and interest rate for next two years = 2%

2nd Financial institution:

interest rate = 2.49% for three years

Let the principal amount deposited be P

We assume that the interest is compounded continuously.

Then for the 2nd bank-

Amount = P[tex]e^{rt}[/tex]

here, r = 2.49%

= 0.0249

Amount = P[tex]e^{0.0249 * 3}[/tex]

= P[tex]e^{0.0747}[/tex]

Thus, the total amount of money in the account in the second bank after 3 years will be given by the function- P[tex]e^{0.0747}[/tex].

Based on the alternate exterior angle theorem, if m<1 = m<2, the statement which is true is that: B. n || m.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed are congruent or angles of equal measure.

In this context, we can reasonably infer and logically deduce that the true statement which best proves that lines n and m are parallel is that angle 1 is congruent to angle 2 because by definition, all alternate exterior angles are congruent, if two (2) parallel lines are cut by a transversal.

Correct answer is B. The value of tan²(e)+1 is sec²(e).

Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios.

In geometric figures, unknown angles and distances are derived from known or measured angles using trigonometric functions. The necessity to calculate angles and distances in disciplines like astronomy, mapmaking, surveying, and artillery range finding led to the development of trigonometry.

Answer:

a punch recipe calls for one and 12 quarts of sparkling water

Step-by-step explanation:

Answer:

Sparkling water: 50 quarts

Grape Juice: 25 quarts

Step-by-step explanation:

The punch recipe uses 1 1/2 quarts of water and 3/4 quarts of grape juice

That would make a total of

1 1/2 + 3/4 = 3/2 + 3/4 = 6/4 + 3/4 = 9/4 quarts of punch

Therefore to make 75 quarts, we have to figure out how many of 9/4 quarts would be needed.

This is 75 ÷9/4

Dividing by 9/4 is same as multiplying by 4/9

75 ÷9/4 = 75 x 4/9 = 300/9 = 100/3

So we will need 100/3 times as much of both ingredients

For sparkling water this would be

1 1/2 x 100/3 = 3/2 x 100/3 = 300/6 = 50 quarts

For grape juice we will need
3/4 x 100/3 = 300/12 = 25 quarts
(Or we can subtract 50 from 75 to get 25 quarts)

By using the fact that the two lines with the purple arrow are parallel, We can conclude that the angles are y = 133° and x = 47°

First,  notice that the two lines with the purple arrow are parallel lines, and these lines are intersected by the same line, then the 4 angles formed in the above line are the same ones than in the below line.

So, if the angle in the fourth quadrant of the above intersection is the same as the angle in the fourth quadrant of the below intersection, then we can see that:

y = 133°

And x + y should be equal to 180°, then:

133° + x = 180°

x = 180° - 133° = 47°

We can conclude that the angles are y = 133° and x = 47°
