Bobby Borrowed 24,000 from two different banks to start a business One Bank charge the equivalent of 4% simple interest in the other charge 5.5% interest if the total interest after 1 year was $990 determine the amount borrowed from each Bank

The total cost function based on the number of games sold can be written as C(x) = $6200 + $0.90x. This equation depicts that for every game produced and sold, the total cost increases by $0.90 from a base cost of $6200.

In this particular scenario, fixed costs are constant and turnover does not affect them, hence, a fixed cost of $6200. Variable costs, on the other hand, depend on the quantity produced, which in this case, is $0.90 per unit.

Therefore, as the production output - denoted as 'x' - increases, variable costs also increase, forming a direct relationship. According to the given information, the cost function, denoted as 'C', which represents the total cost, will be the sum of both fixed and variable costs.

So, the total cost function based on the number of games sold, can be written algebraically as: C(x) = $6200 + $0.90x.

This equation implies that for each game produced and sold, the total cost increases by $0.90, with a starting cost of $6200, the fixed costs.

Answer:

Step-by-step explanation:

The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below

68% of data falls within the first standard deviation from the mean.

95% fall within two standard deviations.

99.7% fall within three standard deviations.

The distribution of the IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 15.

Therefore, the range of IQ scores that many (68%) people have is between

100 - 15 and 100 + 15

It becomes

85 to 115

The range of  IQ scores for 68% of the people varies from 85  to 115

Given that the distribution of IQ (Intelligence Quotient) is approximately normal in shape

[tex]\rm Mean\; IQ =\mu = 100 \\Standard\; deviation = \sigma = 15[/tex]

According to the empirical relation for normal curve 68% of the data lies in the range

[tex]\rm \mu + \sigma\; to \; \mu - \sigma[/tex]

So the  lower limit of the range of  the normal distribution of IQ score  = 100 -15 = 85

The upper limit of the range of the normal distribution of IQ score  = 100 + 15 = 115

So we can conclude that the range of  IQ scores for 68% of the people varies from 85  to 115

Answer: 2,970

Step-by-step explanation:

The number of ways to arrange n things such that a things are identical , b things are identical , and so on is  [tex]\dfrac{n!}{a!\cdot b!\cdot ....}[/tex] .

As per given , we have

Number of Geometry books = 2

Number of Algebra books = 8

Number of Pre-Calculus books =2

Total books = 2+8+2=12

Then, the number of ways to arrange them : [tex]\dfrac{12!}{2!\cdot 8!\cdot 2!}[/tex]

[tex]=\dfrac{12\times11\times10\times9\times8!}{2\times8!\times2}=2970[/tex]

Hence, the total number of ways to arrange 2 Geometry books, 8 Algebra books and 2 Pre-Calculus books is 2,970.

To find the number of arrangements of different books on a shelf, we use the concept of permutations of multiset in combinatorics. For 12 books (2 Geometry, 8 Algebra, 2 Pre-Calculus), the number of arrangements is the factorial of the total (12!) divided by the product of factorials for each group of identical items (2!, 8!, 2!).

The question is asking how many ways you can arrange identical books of different subjects on a shelf. Here, we need to use the concept of permutations of multiset, often used in combinatorics. For 12 books in which 2 are Geometry, 8 are Algebra and 2 are pre-Calculus, the number of permutations is given by 12! / (2! * 8! * 2!). This formula is derived from the general principle of permutations of multisets where you divide the factorial of the total number of items by the product of factorials for each group of identical items.

Answer:the first place seller receives $56

The second place seller receives $28

The third place seller receives $20

Step-by-step explanation:

Let x represent the amount that the first place seller would receive.

Let y represent the amount that the second place seller would receive.

Let z represent the amount that the third place seller would receive.

The second place winner will receive 8 more dollars than the third place winner. This means that

z = y - 8

The first place seller will receive twice as much as the second place seller. It means that

x = 2y

The profit portion they will share is $ 104. It means that

x + y + z = 104 - - - - - - - - - - - 1

Substituting z = y - 8 and x = 2y into equation 1, it becomes

2y + y + y - 8 = 104

4y = 104 +8 = 112

y = 112/4 = 28

x = 2x = 2 × 28

x = 56

z = y - 8 = 28 - 8

z = 20

Answer:

number  ,proportion

Step-by-step explanation:

Data is a collection of facts, such as numbers, words, measurements, observations. Data is organised in graphs or charts for analysis and conclusions.

A frequency distribution lists the number of occurrences of each category of data.

A relative frequency distribution lists  the proportion of occurrences of each category of data.

A frequency distribution lists the number of occurrences, and a relative frequency distribution lists the proportion of occurrences of each category of data. Frequency tables compile occurrences, while relative frequencies are calculated as a ratio of the frequency to the total number of observations. Histograms and bar graphs visually represent these distributions.

A frequency distribution lists the number of occurrences of each category of​ data, while a relative frequency distribution lists the proportion of occurrences of each category of data. When we compile a frequency table, the data are organized so that we know how many times a particular value or category occurs. For example, a frequency distribution can inform us that 15 students spend five hours or more studying for an exam.

Conversely, a relative frequency distribution provides us with a ratio or fraction that represents how often a value appears relative to the entire set of data. To calculate relative frequency, one would divide each frequency by the total number of observations. If 20 students were surveyed, and 5 studied for more than five hours, the relative frequency would be 5/20 or 0.25 (which can also be expressed as 25%).

Graphical representations such as histograms and bar graphs are valuable for visualizing both frequency and relative frequency. A histogram is suitable for displaying the distribution of interval or ratio variables, particularly with a large number of cases. Bar graphs are more commonly used for nominal or ordinal data, which usually involves fewer categories.

Answer:

Segments with positive slope, negative slope, zero slope and undefined slope are indicated in the attach.

Step-by-step explanation:

When you represent or consider a segment in a coordinate axis system, the slope of the segment is the variation in "x" axis in relation to variation in "y" axis, it means the quotient Δx/Δy. If we select two different pairs of points (x1, y1) (x2, y2) ⇒slope =  Δx/Δy ⇒ slope = (x2 - x1)/(y2 - y1).

There four main options:

- If  Δx/Δy > 0 ⇒ Positive slope (In this case: Δx >0 and Δy> 0 or Δx˂ 0 and Δy ˂  0).

- If Δx/Δy ˂  0 ⇒Negative slope (this happens when Δx > 0 and Δy˂0 or

Δx˂0 and Δy>0)

- If Δx/Δy = 0 ⇒ zero slope (This happens when Δx =0).

-If Δx/Δy =∅ ⇒ undefined slope (only when Δy = 0).

Given this explanation and considering the word MATH in a coordinated system, we clasiffied the segments as you can see in the attach. Segments denoted by: 1 have positive slopes, 2 negative slopes, 3 zero slope and 4 unddefined slope.

Answer:

Step-by-step explanation:

Given:

Number of fish tanks = 8

Number of gold fish = 216

We need to find the number of goldfish in each tank.

Solution:

Now we know that;

Number of gold fish must be equal in each tank.

To find the number of gold fish in each tank we will divide Number of gold fish by Number of fish tanks.

framing in equation form we get;

number of gold fish in each fish tank = [tex]\frac{216}{8} = 27 \ fish[/tex]

Hence Each tank would have 27 gold fish in it.

Answer: x = 5

Step-by-step explanation: This is an isosceles triangle, which means two sides are equal in length and two angles are equal in measurement.

Line BA = Line BC

Similarly, Angle A = Angle C

Angle A plus Angle C equals 146°

Also the sum of the interior angles of a triangle is 180°

Therefore, 146 + (6x + 4) = 180

Subtract 146 from both sides of the equation

6x + 4 = 34

Subtract 4 from both sides of the equation

6x = 30

Divide both sides of the equation by 6

x = 5

Final answer:

Ms. Vargas wants to sell 2/3 of her 4/5 acre of land. By multiplying the fractions, we find that she intends to sell 8/15 of an acre to her neighbor.

Explanation:

Ms. Vargas owns 4/5 of an acre of land and wants to sell 2/3 of her land. To find out what fraction of an acre Ms. Vargas wants to sell, we need to multiply these two fractions together.

Here is the step-by-step calculation:

Multiply the numerators (top numbers) of the fractions: 4 × 2 = 8.

Multiply the denominators (bottom numbers) of the fractions: 5 × 3 = 15.

Combine the products to get the fraction of the land she wants to sell: 8/15 of an acre.

Therefore, Ms. Vargas wants to sell 8/15 of an acre of her land to her neighbor.

You can use any of the available methods for solving system of linear equations like method of elimination or method of substitution etc.

There are no solutions to the given system of equations.

For that , we will try solving it first using the method of substitution in which we express one variable in other variable's form and then you can substitute this value in other equation to get linear equation in one variable.

If there comes a = a situation for any a, then there are infinite solutions.

If there comes wrong equality, say for example, 3=2, then there are no solutions, else there is one unique solution to the given system of equations.

The given system of equations is

[tex]2x - 6y = 5\\x - 3y = -12[/tex]

Using second equation to get x in terms of y

[tex]x - 3y - 12\\x = 3y - 12[/tex]

Substituting this expression for x in place of x in first equation,

[tex]2x - 6y = 5\\2( 3y - 12) - 6y = 5\\6y - 24 - 6y = 5\\-24 = 5[/tex]

The last statement we got is incorrect.

That conclusion above shows that the given system of equation has no solution.

We could've detected it from the fact that

[tex]2x - 6y = 5\\\text{dividing both sides by 2}\\x - 3y = 2.5[/tex]

Converting both equations to slope intercept form, we get:

[tex]x - 3y = 0.5\\\\y = \dfrac{1}{3}x - \dfrac{1}{6}[/tex]

and

[tex]x - 3y = -12\\\\y = \dfrac{1}{3}x + 4[/tex]

We see that both lines have same slope but different y intercept, which tells that both lines are parallel but not coincident, thus, not intersecting and thus, no common point(common points are solutions).

The graph of this system of linear equation is given below where lines represented by both linear equations are plotted.

Thus,

There are no solutions to the given system of equations.

Step-by-step explanation:

Given:

m arc AC = 69

Segment AB is tangent to circle O at point A.

We need to find the ∠ ABC

Solution:

Now we can say that;

By inscribed angle theorem which states that;

"Central angle is equal to arc subtended by it."

m∠O = 69 (Central angle)

Also Given:

Segment AB is tangent to circle O at point A.

Now by radius tangent property which states that;

"Radius which touches to closet point on the tangent is always perpendicular."

so we can say that;

m∠OAB = 90

Now in Δ OAB.

m∠O = 69

m∠OAB = 90

Now we know that;

"Sum of all angles of triangle is 180."

m∠O + m∠OAB + m∠ABO = 180

Substituting the values we get;

[tex]69+90+m\angle ABO=180\\\\159+m\angle ABO=180[/tex]

Subtracting both side by 159 we get;

[tex]159+m\angle ABO-159=180-159\\\\m\angle ABO=21[/tex]

Now we can say that;

m∠ABO = m∠ ABC = 21 (same angles)

Hence  m∠ ABC is 21.

2 hours working on problems, 2 hours reading

Step-by-step explanation:

The question is incomplete. Here is the complete question:

Ben is a hard-working college senior. One Thursday, he decides to work nonstop until he has answered 150 practice problems for his math course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem.

Time          |   Total Problems Answered

8:00 AM   |   0

9:00 AM   |   60

10:00 AM |   105

11:00 AM  |   135

Noon   |   150

The marginal, or additional, gain from Ben's first hour of work, from 8:00 AM to 9:00 AM, is 60 problems.

The marginal gain from Ben's third hour of work, from 10:00 AM to 11:00 AM, is 30 problems.

Later, the teaching assistant in Ben's math course gives him some advice. Based on past experience, the teaching assistant says, "working on 40 problems raises a student's exam score by about the same amount as reading the textbook for 1 hour". For simplicity, assume students always cover the same number of pages during each hour they spend reading.

Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading?

The marginal or additional gain in the above question is calculated by obtaining the difference in problems solved between two selected time frames . For example, the marginal or additional gain from Ben's 11 AM to Noon work is :

Additional gain from 11 AM to Noon = 150 - 135 = 15 problems

Ben should therefore make his decision at the margin. Each hour, he should select the option that will improve his exam grade by the largest amount. If he can do more than 40 problems in an hour, working on problems will help raise his grade more for that hour than reading would.The marginal gain from the first hour is 60 problems. The marginal gain from the second hour is 45 problems. He will stop there, because he will get only 30 problems done if he spends the third hour working on problems. Therefore, he should stop working on problems and spend his remaining 2 hours reading instead.

Answer:

100

189

83

Step-by-step explanation:

Firstly, we can see that there are three aircrafts. Let the number of aircrafts in the second aircraft be x.

Then the first has 89 more seats meaning it has a total seats of x + 89

The third has 17 fewer seats meaning x - 17

Now we are expected to find the number of seats on each of the aircraft officials.

We add all and then sum to the total 372.

This means

x + x + 89 + x - 17 = 372

3x + 72 = 372

3x = 300

x = 300/3 = 100

The aircrafts thus have 100 seats, 189 and 83 seats in no particular order

The exact value of cotФ  is  [tex]\frac{\sqrt{7}}{3}[/tex]  

Step-by-step explanation:

Given as:

The value of cosec Ф = [tex]\frac{-4}{3}[/tex]

Let the value of  cotФ = x

Now, According to question

∵  sinФ = [tex]\frac{1}{cosec\Theta }[/tex]                       .....1

Put the value of cosec Ф = [tex]\frac{-4}{3}[/tex] in eq 1

i.e  sinФ = [tex]\frac{1}{\frac{-4}{3} }[/tex]

Or,  sinФ = [tex]\frac{-3}{4}[/tex]

Again

∵ cosФ = [tex]\sqrt{1-sin^{2}\Theta }[/tex]

So,  cosФ = [tex]\sqrt{1-(\frac{-3}{4})^{2}}[/tex]

Or, cosФ = [tex]\sqrt{1-(\frac{9}{16})}[/tex]

Or,  cosФ = [tex]\sqrt{\frac{16 - 9}{16})}[/tex]

∴  cosФ = [tex]\frac{\sqrt{7}}{4}[/tex]

Again

we know that cotФ = [tex]\frac{cos\Theta }{sin\Theta }[/tex]

So,  cotФ  = [tex]\frac{\frac{\sqrt{7}}{4}}{\frac{-3}{4}}[/tex]

Or,  cotФ  = [tex]\frac{-\sqrt{7}}{3}[/tex]

As according to question sinФ lies in third quadrant

So,  cotФ  =  [tex]\frac{\sqrt{7}}{3}[/tex]

Hence, The exact value of cotФ  is  [tex]\frac{\sqrt{7}}{3}[/tex]   . Answer

Answer:

18.3 pounds of water must evaporate to make it 8% solution

Step-by-step explanation:

Brine is a solution containing water & salt

Weight of brine solution = 50 pounds

amount of salts = 5% of 50 pounds = (5 ÷ 100) × 50 = 2.5 pounds.

Amount of water = 50 - 2.5 = 47.5 pounds

The new solution is to be made 8%, which indicates that 2.5 pounds of salt is going to be equivalent to 8% of the new salt and some amount of water has to be evaporated for the amount of salt to increase

Using direct relation expression

8% of the solution equivalent to 2.5 pounds of salt

100% will be equivalent to X pounds of solution

Upon cross multiplication,  

X = (100 × 2.5) ÷ (8) = 31.25 pounds of solution

There amount of water that must evaporate is difference between weight of initial solution & final solution

Amount of water to be evaporated = 50 - 31.25 = 18.25 pounds ∞ 18.3 lbs
