The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The amount earned by 217% more from last year to this year.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Amount earned last year = 1,459,632,852

Amount earned this year = 4,632,859,678

The best estimate of the amount earned this year than last year.

= [ (4,632,859,678 - 1,459,632,852 ) / 1,459,632,852 ] x 100

= ( 3173226826 /1,459,632,852 ) x 100

The kind of sequence is a prime number if Norma cuts 3, 5, 8, 13 roses from the four bushes.

A prime number is a natural number higher than 1 that is not the sum of two lesser natural numbers. A composite number is any natural number that is more than 1 but not a prime. As an illustration, the number 5 is prime since there are no other ways to write it either a product than as 1 5 or 5 1. The basic arithmetic theorem states that every natural number greater than 1 is either a prime itself or can be factored as a product of primes that is unique up to their order, making primes a prominent concept in number theory.

Given,

The number of roses cut by Norma from the first rose bush are 3 roses.

And from the second rose bush are 5 roses and from the third rose bush are 8 roses.

And from the fourth rose bush are 13 roses.

1     2     3     4

Answer:

y = 10 , ∠ C = 40° , ∠ D = 76°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ DEF is an exterior angle of the triangle , then

∠ C + ∠ D = ∠ DEF , that is

4y + 7y + 6 = 116

11y + 6 = 116 ( subtract 6 from both sides )

11y = 110 ( divide both sides by 11 )

y = 10

Then

∠ C = 4y = 4(10) = 40°

∠ D = 7y + 6 = 7(10) + 6 = 70 + 6 = 76°

Answer:

y = 10

∡C = 40°

∡D = 76°

Step-by-step explanation:

Supplementary angles sum 180°

116° and ∡E are supplementary angles:

116 + E = 180°

E = 180 - 116

E = 64°

∡E = 64°

Internal angles of a triangle sum 180°

∡D   + ∡C + ∡E = 180°

7y+6 + 4y + 64 = 180

7y + 4y + 6 + 64 = 180

11y + 70 = 180

11y = 180 - 70

11y = 110

y = 110/11

y = 10

Then:

∡C = 4y = 4*10 = 40°

∡D = 7y + 6 = 7*10 + 6 = 70 + 6 = 76°

What do you mean by transformation?

Transformation is a collective term for four specific ways of manipulating the shape and position of points, lines, or geometric figures. The original shape of the object is called the master, and the final shape and position of the object is the image under transformation. There are four types of transformations in mathematics

1) When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x).

Therefore, image of the coodinate A(6,2) be A'(-2,6)

image of the coodinate B(3,4) be B'(-4,3)

image of the coodinate C(2,8) be C'(-8,2)

2) A transformation that preserves congruence is called an isometry.  In other words, a transformation in which the Image and Pre-Image have the same side lengths and angle measurements. Translations, reflections, and rotations are isometries.

19.1 is the proportionality constant. It shows that Jack makes 19.1 dollars and cents for every hour he works.

Given that e = 19.1 may be used to represent the percentage between Jack's total wages in dollars and cents and the number of hours he works, h, the relationship between these two variables is one of proportionality.

We need to determine the constant of proportionality.

The constant of proportionality in the preceding equation, e = 19.1h, stands for the constant ratio between the total number of hours worked (h) and the total amount earned in dollars and cents (e).

The amount of money Jack makes for each hour he works is determined by this constant.

We can compare the provided equation with the formula for a proportional connection, which is: to determine the constant of proportionality.

e = k × h

Here, "k" represents the constant of proportionality.

We need to identify the value of "k" from the given equation e = 19.1h.

We can see by comparing the two equations that the proportionality constant, "k," is 19.1.

This indicates that Jack makes $19.1 for each hour that he works. The fixed rate of 19.1 (constant) represents the rise in his pay for each additional hour he works.

Hence, the constant of proportionality from the number of hours worked to total earnings is 19.1 dollars per hour.

a) The taxes to be paid for someone with a taxable income of $39,000 are of: $4,680.

b) The piece-wise function is defined as follows:

c) The tax rates are used as the slope for each linear definition of the piece-wise functions, while the bounds of the intervals are used to calculate the intercept.

The amount of taxes owed is obtained applying the proportion of the tax rate relative to the annual salary.

The tax rate for a taxable income of $39,000 is of 12%, hence the amount is given as follows:

0.12 x 39000 = $4,680.

The piece-wise functions for this problem are all derived considering the intervals with the tax brackets,

For the first tax bracket, the proportion is merely applied, as follows:

0.1x, 0 ≤ x ≤ 10275;

For each bracket, starting on the second, the maximum tax rate of the previous rate is calculated, and added to the excess of the income relative to the maximum of the previous tax bracket multiplied by the proportion.

For the first tax bracket, the maximum income is of:

$10,275.

The maximum tax of the first tax bracket is of:

0.1 x 10275 = 1027.5. -> the maximum value of the nth bracket is the starting value of the nth+1 bracket.

Then the function for the second bracket rate is obtained as follows:

f(x) = 1027.5 + 0.12(x - 10275), 10276 ≤ x ≤ 41175.

The same procedure is applied to any of the remaining brackets, taking the previous bracket to obtain the function.

In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain. For all values of a and b, f = (a,b)|

If every element in set A has exactly one and only one image in set B, then the relation is said to be a function.

A function is a relation from a non-empty set B such that its domain is A and it never has the same first member in two different ordered pairs.

The size of the subculture or group under studied determines the sampling size in ethnography. In this regard, it might not be possible to predetermine the participant count. The complete subculture or group being studied serves as the study sample size in anthropological research.

The non-random sample that best resembles stratified random sampling is quota sampling.

Using the non-probability sampling technique of quota sampling, researchers select a sample of people who are typical of the population. These people are chosen by researchers based on specific traits or qualities. In order to use market research samples for data collecting, they decide on and set sample quotas. These samples accurately reflect the entire population. The interviewer's or researcher's knowledge of the population will be the only factor used to select the final subgroup.

Probability sampling means that every member of the population has a chance of being selected.

There are four main types of probability sample.

Simple random sampling.

Systematic sampling.

Stratified sampling.

Cluster sampling.

For instance, a tobacco company would want to know which age group in a given city loves which brand of smokes. The age groups of 21–30, 31–40, 41–50, and 51+ are subject to survey quotas. Based on these findings, the researcher makes an estimation of the smoking trend in the city's inhabitants.

Since the team's student lineup is not crucial, a mixture will be employed.

C(10,5) = 252 is the number of possible methods to choose 5 students from a class of 10.

Rest Team B will consist of 5 students. Consequently, there are 252 items in the sample space.

Let two women join team A. then the number of methods for choosing the final three members from the eight remaining members C(8,3) = 56

Likewise if two girls are in team B then possible number of different groups is 56.

Therefore total number of different groups such that two girls  are in one team is 56+56 = 112.

The required probability is

P(two girls  are in one team) = 112 / 252
