The number of three letter words that can be formed from the 4 letters "FGHI" is

(a) when repetition allowed is 64

(b) when repetition not allowed is 24 .

In the question ,

the four letters are given as "FGHI" ,

we need to find the how many 3 letter words  can be formed ,

(a) when repetition is allowed

= (selecting a letter from 4 given letters)×(selecting a letter from 4 given letters)×(selecting a letter from 4 given letters) .

= ⁴C₁ × ⁴C₁ × ⁴C₁

= 4 × 4 × 4              .... because ⁴C₁ = 4

= 64

(b)  when repetition not allowed

= (selecting a letter from 4 given letters)×(selecting a letter from the remaining 3 letters)×(selecting a letter from the remaining 2 letters)

= ⁴C₁ × ³C₁ × ²C₁

= 4 × 3 × 2

= 24

Therefore , The number of three letter words that can be formed from the 4 letters "FGHI" is  (a) when repetition allowed is 64  , (b) when repetition not allowed is 24 .

Answer:

$25.67

Step-by-step explanation:

120 - 43 = 77

77/3 = 25.67

Answer:

We use the attached graph

a. The maximum profit is the y value that is the value of P(x) that reaches maximum. From the graph the maximum value of P(x) is 675

So the maximum profit the florist will earn from selling bouquets = $675

b. Break even is the point where the profit p(x) becomes 0

From the graph we can see that P(x) =0 at x= -10 and x=20

x=-10 is invalid

So, break even after 20 one- dollar decreases

c. The interval of number of one dollar decreases is where the profit P(x) is greater than 0.

From the graph its very clear that the profit P(x) is greater than 0 in the interval 0 to 20.

So, The interval of number of one dollar decreases for which the florist makes a profit from celebration bouquet is (0, 20)

Answer:

  3, 4, 5

Step-by-step explanation:

You have parallel lines crossed by a transversal, and one obtuse angle marked as 99°. You want the angle designators of the congruent angles.

Where a transversal crosses parallel lines, corresponding angles are congruent. In this figure, angle 3 corresponds to the one marked 99°, so it is congruent.

Anywhere that lines cross, vertical angles are congruent. Angles 3 and 4 are vertical angles, as are angle 5 and the one marked 99°.

Hence angles 3, 4, 5 are all congruent to the one marked 99°.

__

Additional comment

You may have observed that the listed congruent angles are all of the obtuse angles in the figure. Similarly, all acute angles in the figure are congruent. Since the acute and obtuse angles are supplementary (form linear pairs), angles 1, 2, 6, 7 are all 81°.

1) The interest that will accumulate for Marlie during the 4.5-year non-payment period is $3,629.34.

2a) The new principal when Marlie begins making loan payments will be $22,429.34.

2b) Marlie will pay an additional $9,622.19 in interest for 10 years, including the 4.5-year period interest of $3,629.34 to make a total of $13,251.53.

3. If Marlie paid interest during the 4.5-year period, the total interest she will pay, thereafter, is $8,065.20.

4. Marlie's only interest payment due on January 1 is $67.21.

5a) With a private loan at 7.8% APR, Marlie's monthly payment is $226.11.

5b) The total amount Marlie will pay back with a private loan at 7.8% APR is $27,133.67.

5c) Based on a private loan, Marlie's total interest is $8,333.67.

The interest on federal student loans is based on simple interest, unlike the interest on private loans, which is compounded.

We can compute simple interest using the simple interest formula (PRT/100) and compounded interest using an online finance calculator.

Student loan amount = $18,800

Interest rate = 4.29%

Non-payment period = 4.5 years

Loan repayment period = 10 years

Interest for the 4.5-year non-payment period = $3,629.34 ($18,800 x 4.29% x 4.5 years)

New Principal after 4.5 years = $22,429.34 ($18,800 + $3,629.34)

Additional interest on the loan after 4.5 years = $9,622.19 ($22,429.34 x 4.29% x 10 years).

Total interest = $13,251.53 ($9,622.19 + $3,629.34)

Interest for 10 years on principal = $8,065.20 ($18,800 x 4.29% x 10 years).

Only Interest monthly payment = $67.21 ($18,800 x 4.29% x 1/12)

N (# of periods) = 120 months (10 years x 12)

I/Y (Interest per year) = 7.8%

PV (Present Value) = $18,800

FV (Future Value) = $0

Results:

Monthly payments (PMT) = $226.11

Sum of all periodic payments = $27,133.67

We can solve the linear equation in one variable by moving the variables to one side of the equation, and the numeric part on the other side of the equation. For example, x - 1 = 5 - 2x can be solved by moving the numeric parts on the right-hand side of the equation which is summed up to be 6, while keeping the variables on the left side which sums up to be 3x. Hence, we get x + 2x = 5 + 1. Thus, 3x = 6. This gives x = 2.

Similarly, we got the value of x which is 25.

The weight of each small box is 25 pounds while the weight of each large box is 45 pounds

We know that we can be able to find the mass of each type of box from the use of simultaneous equations. Al we need to do is to form two systems of equations. Let the weight of each small box be x and the weight of each large box be y then;

x + y = 70 ------ (1)

50x + 70y = 4000 ----- (2)

x = 70 - y ------ (3)

Substitute equation (3) into (2)

Then;

50(70 - y) + 70y = 4000

3500 - 50y + 70y = 4000

20y = 4000 - 3500

20 y = 500

The correlation coefficient, r, of the data (1 , 6) , (3 , 4) , (5 , 2) is calculated as: r = -1

The correlation coefficient can be described as a numerical value that ranges from -1 through 0, to 1. It is a test of the strength of the relationship between two different variables. It is denoted as "r".

The formula for finding the correlation coefficient (r) between two variables x and y is given as:

r = Σ(xi - mean of x)(yi - ȳ) / √(Σ[xi - mean of x)²Σ(yi - ȳ)²]

Given the following data:

(1 , 6) , (3 , 4) , (5 , 2)

Therefore, the table in the attached diagram shows how to derive each of the variables in the formula used for calculating the correlation coefficient, r, between X and Y.

Step-by-step explanation:

Primero hallemos cuantas horas trabaja Esther en un día

2 es el número de horas que trabaja en cada turno de la mañana y [tex]x[/tex] el número de horas que trabaja en su turno de la noche (en este momento desconocemos el valor de [tex]x[/tex] y es el que queremos hallar). Ahora se tiene que en 4 días ester trabaja 28 horas en total, por lo tanto, multiplicamos 4 a ambos lados de la ecuación para conservar la igualdad

[tex]4\times (2 + x) = horas\ en \ cuatro \ dias[/tex]

[tex]8+4x= 28[/tex]

The length of the rectangle-shaped classroom is 15 meters.

We have a classroom. The shape of the classroom is rectangular. The length of the classroom is 3 meters more as compared to its width. The area of the rectangular classroom is 180 square meters. We need to find the length of the classroom.

Let the width of the rectangle be represented by the variable "x". The length of the rectangle is "x + 3". We will use the formula for the area of a rectangle. The area of a rectangle is the product of its length and width.

A = x*(x + 3)

180 = x² + 3x

x² + 3x - 180 = 0

We will use the quadratic formula to solve for the values of "x".

x = [-3 ± √(3² - 4(1)(-180))]/2(1)

x = [-3 ± √(9 + 720)]/2

x = [-3 ± √729]/2

x = [-3 ± 27]/2

The values of the variable "x" are -15 and 12. The negative value is rejected because the measure of a dimension cannot be negative. Hence, the value of "x" is 12. The length of the rectangular classroom is x + 3 = 12 + 3 = 15 meters.

The probability that the song that was picked was one she liked or one she has not heard but did not enjoy is 17/22.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that:

Total number of songs = 22

Probability of liked song  = 10/22

The probability of she has not heard but did not enjoy =  7/22

The probability that the song that was picked was one she liked or one she has not heard but did not enjoy:

= 10/22 + 7/22

Step-by-step explanation:

Tip: Think of how a number line is displayed: negative numbers are on the left side of the mid-point, zero in most cases, and positives numbers are to the right of the mid-point.

Since the exponent is a negative number, you know that you need to move the decimal point to the left the same number of places as the exponent. In this problem, the exponent is –3, meaning that you need to move the decimal point 3 places to the left.
