The "net asset value" is used to compute both entry load as well as exit load as a percentage.

Entry load is the sum of money or fee that an investor must pay to join a scheme or a company as an investment.

Exit loads are fees or amounts collected from investors for quitting a plan or a corporation as a shareholder.

Thus, the "net asset value" is used to compute both entry load as well as exit load as a percentage.

To graph it first, consider line:

Find two points on the line.

Let them be x- and y-intercepts:

Now, plot the two points.

Next, draw a dashed line trough the two points. Dashed line because the line is not included into solution set, due to '<' sign.

The last step, shade the area below the line. Below the line because 'y <' means 'y-values less than' which appears below the line.

Answer:

See attachment.

Step-by-step explanation:

Given linear inequality:

[tex]y < \dfrac{1}{2}x+2[/tex]

When graphing inequalities, temporarily replace the inequality sign for the equals sign:

[tex]\implies y=\dfrac{1}{2}x+2[/tex]

Find two points on the line by substituting two values of x into the equation:

[tex]x=0 \implies y=\dfrac{1}{2}(0)+2 =2\implies (0, 2)[/tex]

Step-by-step explanation:

2 is a common sample in the 2 events, therefore they are not mutually exclusive.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means. You will discover the likelihood of outcomes for a random experiment using this fundamental probability theory, which is also applied to the probability distribution.

Two occurrences are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin toss, which can result in either heads or tails but not both, provide a clear illustration.

If we roll a dice which is fair

Events that we get to shw even are = {2, 4, 6}

Answer: $2.25

Step-by-step explanation:

We are required to find the cost per kilometer of Emmanuel.

   The cost per kilometre is $2.25 OR $2 and 25cents.

According to the question, the total cost of the journey = $32

The total distance covered during the journey =

14 2/9 km

Therefore, the cost per kilometre can be evaluated mathematically as follows;

Cost per kilometer = cost of the journey ÷ Distance of the journey

= 32 ÷ 14 2/9

By converting 14 2/9 to an improper fraction; we have;

   = 32 ÷ 128 / 9

   = 32 × 9/128

   = (32×9) / 128

   = 288 / 128

   = 2 32/128

   = 2.25 dollar per kilometer

Therefore, the cost per kilometer is $2.25

Therefore , the solution to the given problem of composite number comes out to be Since Morgan's claim regarding Composite Numbers is true, we can infer that he is right.

Prime numbers can really be expressed as the sum of two different numbers. The sum of two or more numbers is what is referred to as a composite number. Examples of prime numbers include 2,3,5,71,11 since they only have two factors, one and itself. Examples of composite numbers include 4,6,8,10,12 since they contain more than two contributing variables.

Here,

we can see Morgan's claim that any numbers with a 2 in the place of a one are composite numbers.

We can conclude that Morgan is correct given the prior description of composite numbers by stating that all numbers with a 2 in the place of a one are composite numbers.

In actuality, any even integer—aside from 2—is a composite number.

Answer:

true because i guessed and got it right trust me

Based on the equation that models the company's profit as P = 4x - 10,000, if 5,000 units are sold, the company's profit is $10,000.

The profit equation shows the difference between the revenue and the costs during a financial period.

The revenue is a product of the units sold and the number of units.

Profit, P = 4x - 10,000

Number of units sold = x

If 5,000 units are sold:

The profit = $10,000 (4 x 5,000 - 10,000)

Check:

Total revenue = $20,000 (4 x 5,000)

Unit selling price = $4

Number of units sold = 5,000

Total costs = $10,000

Thus, using the profit equation, the company generated a profit of $10,000 from selling 5,000 floats for children.

The question is a word problem, where; the amount of money Alex has is the same as the amount Monte will have if he gives Alex $12, and the amount of money Monte will have will be twice the amount with Alex if he receives $6 from Alex, indicating that the amount of money Alex has is $30, while the amount of money with Monte is $54.

A word problem is a verbal presentation of a mathematical or science question, using words and sentences, rather than numbers and symbols, and for which the solution is found mathematically, or by using standard scientific steps.

Let x represent the amount of money Alex has, and let y represent the amount of money Monte has, we get;

x + 12 = y - 12...(1)

2·x = y + 6...(2)

Adding 12 to both sides of equation (1), we get;

x + 12 + 12 = y - 12 + 12

x + 24 = y - 0 = y

x + 24 = y

y = x + 24

Plugging in the value of y into equation (2), we get;

2·x = y + 6

2·x = x + 24 + 6 = x + 30

2·x = x + 30

Subtracting x from both sides of the above equation, we get;

2·x - x = x + 30 - x

x = x - x + 30 = 0 + 30

x = 30

The amount of money Alex has, x = $30

y = x + 24

Therefore; y = 30 + 24 = 54

After 1 year Charles will earn $187 more kelvin

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

The interest rate of Kelvin's investment is 2.6% anually.

The interest rate of Charles' investment is 4.3% anually

The amount received by kelvin = 11000 + 11000× 2.6/100

= 11000+ 286 = $11286

The amount received by Charles = 11000 + 11000× 4.3/100

A. The interest Bianca earned for a period of 3 years is $382.50. The correct option is B. $382.50

B. The number of years Bianca kept the account open is 11 years

From the question, we are to calculate how much interest Bianca will earn for a period of 3 years

From the simple interest formula, we have that

S.I = PRT

Where S.I is the simple interest

P is the principal

R is the rate

and T is the time

From the given information

P = $3,000

R = 4.25% = 0.0425

T = 3

Therefore,

S.I = $3,000 × 0.0425 × 3

S.I = $382.50

B.

From the given information, Bianca receives $4,402.50 when she closes the account

Thus,

The simple interest = $4,402.50 - $3,000

Simple interest = $1402.5

We are to calculate how many years Bianca kept the account open. That is, T

Using the formula,

S.I = PRT

$1402.5 = $3000 × 0.0425 × T

$1402.5 = $127.5 × T

T = $1402.5/$127.5

T = 11
