Solve the equation

5+16w=6-45​

Answers

Answer 1

Answer:

w = 6 / 21.

Step-by-step explanation:

To solve this equation, we first need to get all of the terms with the variable w on one side of the equation and all of the constants on the other side. To do this, we can use the distributive property to combine like terms on each side of the equation.

We can use the distributive property to combine the two terms on the left side of the equation to get 5 + 16w = 21w. This gives us the equation 21w = 6 - 45.

Next, we can add 45 to both sides of the equation to get 21w + 45 = 6 + 45. This simplifies to 21w + 45 = 51.

Finally, we can divide both sides of the equation by 21 to get the value of w. This gives us the equation w = (51 - 45) / 21 = 6 / 21.

Therefore, the solution to the equation is w = 6 / 21.

Answer 2
5+16w=6-45
5+16w=39
16w=39-5
16w=34
w=2.125

There are 24 members of a kayaking club this summer. Next year, Owen hopes the number of members will be 125% of this number.



Write a percent equation in the form part = percent • whole that can be used to find 125% of 24. Use p to represent the part and represent the percent as a decimal.

Answers

The percent equation in the form of p = percent x whole is

p = 1.25 x 24

What is a percentage?

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,

Number of members in the club = 24

Number of members in the club next year = 125% of 24

The percent equation of 125% of 24.

p = 125/100 x 24

p = 1.25 x 24

p = 5/4 x 24

p = 5 x 6

p = 30

Thus,

The percent equation is p = 1.25 x 24

suppose that the rural wage is $2 per day. urban modern sector employment can be obtained with a probability of 0.24 and pays $4 per day. the urban informal sector pays $1 per day. using this information, and making assumptions as needed, predict whether there will be any rural-to-urban or urban-to-rural migration? explain your reasoning, stating explicitly any simplifying assumptions, and show all your work.

Answers

The solution to given problem is  since E(Wu) < Wr, there will be no migration from rural areas .

What does probability theory entail?

The subject of probability in mathematics is concerned with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, with 1 typically signifying certainty and 0 typically signifying impossibility.

Here,

Since ,the rural wage is $2 per day. Urban modern sector employment can be obtained with .24 probability and pays $4 per day. The urban traditional sector pays $1 per day.

As long as the rural pay (Wr) differs from the anticipated urban wage (E(Wu)), according to the Harris-Todaro model, there will be movement between rural and urban areas.

Here, Wr equals $2.00.

Determine the anticipated urban wage now.

E(Wu) = p

*Wum+(1-p)

*Wut

Where p is the likelihood of finding employment in the urban modern sector, which is 0.25, and Wum is the wage for such employment, which is $4.00.

Wut = $1.00 in wages for jobs in the typical urban sector.

Hence, E(Wu) = 0.24*$4.00+0.76*$1.00 = $1.72

Since E(Wu) < Wr, there will be no migration from rural areas .

suppose the estimated regression equation is given by . what are the predicted value of y and the residual when x is 2 and y is observed to be 9?

Answers

The predicted value and residual for y is 9.4 and -0.4 respectively.

In statistics, a regression equation is used to determine whether or not there is a relationship between two sets of data. If you measure a child's height every year, you might discover that they grow about 3 inches per year. A regression equation can be used to model that trend (growing three inches per year). In fact, most things in the real world (from gas prices to hurricanes) can be modelled mathematically, allowing us to forecast future events.

Regression equations can assist you in determining whether your data can be fit to an equation. This is extremely useful if you want to make predictions based on your data, whether they are future predictions or indications of past behaviour.

Given,

Regression equation is y=11-038x

Observed value of y = 9

predicted value of y can be determined by substituting x=2 in the equation

y=11-0.8(2)=11-1.6=9.4

The residual can be calculated by formula,

residual = observed value - predicted value

residual = 9 - 9.4

residual = -0.4

Thus, the predicted value is 9.4 and residual is -0.4.

the measure of ∠ 1 is 50 degrees. what is the measure of ∠ 6 ?

Answers

If the measure of angle 1 is 50° then the measure of angle 2 is 30°.

We know that line l ∥ line m and line p is the transversal.

Let's label the diagram as follows.

Now, by the vertically opposite angles theorem,

we have angle 1 = ∠TPQ = 50°

now ∠P and ∠Q form interior angles,

Hence, by the interior angles theorem, we have

∠P + ∠Q = 180°

The sum of the interior angles of the angles formed by the transversal is 180°.

50° + ∠Q = 180°

subtracting 50° on both sides we get,

∠Q = 180° - 50°

∠Q = 30°

the different geometries that a molecule can attain by bond rotations and bends are called conformations. True/False ?

Answers

TRUE: A molecule can adopt a variety of geometries known as conformations by the rotation and bending of its bonds.

Conformational isomerism, often known as stereoisomerism, is a type of stereoisomerism in chemistry in which the isomers can be changed to one another simply by rotations about formally single bonds. Different conformations refer to any two arrangements of atoms in a molecule that differ by rotation about a single bond, whereas conformations that correspond to local minima on the potential energy surface are more specifically known as conformational isomers or conformers.

As a result, conformational isomers differ from other classes of stereoisomers (such as configurational isomers), where interconversion entails the necessary breaking and reformation of chemical bonds.

what is the difference between descriptive statistics and inferential statistics?

Answers

A data set's attributes are enumerated through descriptive statistics. You can use inferential statistics to test a hypothesis or determine whether your data can be applied to a larger population.

Descriptive statistics concentrate on describing the features of a dataset that are readily evident (a population or sample). In contrast, inferential statistics concentrate on drawing conclusions or generalisations from a sample of data in a larger dataset.

The information from a research sample is described and condensed using descriptive statistics. We can draw conclusions about the larger population from which we drew our sample using inferential statistics.

The area of statistics known as descriptive statistics is focused on providing a description of the population being studied. A type of statistics known as inferential statistics concentrates on inferring information about the population from sample analysis and observation.

4x + 6 = 2 + 3(x + 2)

Here we see that Finn has opened the brackets to write

4x + 6 = 2 + 3x + 2

Here is the point where he made a mistake.

When we have a term that needs to be multiplied by the terms in a bracket, we need to multiply it with every term inside the bracket.

This means, that 3 needs to be multiplied with x as well as 2.

Hence we get

4x + 6 = 2 + 3x + 6

What is Law of Demand ?

According to the Law of Demand, there is an indirect correlation between a good or service's price and the amount of that good or service that customers are willing and able to purchase .In other words, if an item's price increases, people are less able and willing to buy it, and vice versa.

According to the law of demand, the demand curve demonstrates the inverse relationship between the amount of items sought and price.

If the probability of a dancing lady accepting an invitation to dance is 0.18.The accepted number of ladies asked before is 7.14 .

Probability is a branch of mathematics that quantifies the likelihood of an event occurring or the likelihood of a statement being true. Probability is a number between 0 and 1, with 0 generally indicating impossibility and 1 indicating certainty that an event will occur. A simple example is tossing a fair (unbiased) coin. Since the coin is fair, the two outcomes (heads and tails) are equally likely. The probability of heads is the same as the probability of tails. Since no other outcome is possible, the probability of heads or tails is 1/2 (also written as 0.5 or 50%).

The shape is a trapezium. (You can tell as there is one pair of parallel sides.) Therefore, to find the area, the following formula is needed:

Area of a trapezium =  [tex]\frac{a + b}{2} * h[/tex]

a and b represent the parallel sides

Next, plug in the given values:

[tex]154 = \frac{x + 25}{2} * 7[/tex]

Rearrange the equation to get x on its own:

[tex]154 = \frac{x+25}{2} * 7\\\\\frac{154}{7} = \frac{x+25}{2} \\\\22 = \frac{x+25}{2} \\\\22*2 = x + 25\\\\44 = x + 25\\\\44-25 = x\\\\x = 19\\\\[/tex]

Therefore, the answer is 19 inches. Remember your units!

How do you determine a linear function?

Find the number x, If 11/3 of x is 55

Answers

The missing number of the algebraic expression is; x = 15

How to solve algebraic word problems?

We are given the algebraic expression that we should find the number x, If 11/3 of x is 55.

This can be expressed as;

(11/3)x = 55

Multiply through by 3 to get;

(11/3)x * 3 = 55 * 3

11x = 165

Divide both sides by 11 to get;

11x/11 = 165/11

x = 15

Which we conclude that 15 is the missing number.

you draw a two-card hand from a standard deck of 52 cards. what is the probability of drawing a hand that contains exactly 2 face cards (a face card is a king, queen, or jack)?

Answers

By using the concept of probability, it can be calculated that -

Probability that a two-card hand from a standard deck of 52 cards contains exactly 2 face cards (a face card is a king, queen, or jack) = [tex]\frac{11}{221}[/tex]

What is probability?

At first it is important to know about probability of an event.

Probability gives us the information about how likely an event is going to occur.

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

Number of face card = 12

Total number of cards = 52

Probability that a two-card hand from a standard deck of 52 cards contains exactly 2 face cards (a face card is a king, queen, or jack) = [tex]\frac{{12 \choose 2}}{{52 \choose 2}}[/tex]

                                                                                                = [tex]\frac{66}{1326}[/tex]

What is an example of a function equation?

Answers

The example of the function equation is f(x+3) = x² + 8x + 16 .

In the question ,

we have been asked to give an example of the function equation .

The Function Equation is defined as equations where the unknowns are functions, rather than a traditional variable.

For Example :

If f(x+3) = x² + 8x + 16 , then what is f(x)?

the above question is an example of function equation .

to find the solution ,

we let ,y = x + 3; then x = y - 3 .

Substituting the value of x in f(x+3) we get ,

f(y) = 2y² + 2y + 1 .

hence f(x) = 2x² + 2x + 1  that is = (x + 1)²  .

Therefore , the example is  f(x+3) = x² + 8x + 16  .
