920km/

The average speed of an airplane is 920 Km/hr.

We know that,

The average speed of a plane is the distance covered by it in an hour.

                   average speed = total Distance covered/ total time taken

                                          s = d/t

According to the question,      

                                    d = 2300 km.

                                    t = 2.5 hrs.

                          speed (s) = d/t

                                       = 2300 km/ 2.5 hrs.

The previous balance in the account is equivalent to $68.303.

Given is that in August, Billy Quinlin deposited a total of $724 into his checking account. He wrote $585.27 in checks, had a service charge of $29.00 and earned $10.00 in interest. If his current balance is 239.46.

Assume that the initial cost was ${x}. So the total cost after depositing $724, the total amount will be ${x + 724}.

Total amount withdrawn = $585.27 + $29 = $614.27

Amount earned after interest -

10% of 614.27

(10/100) x 614.27

$61.427

Now, we can write -

{x + 724} - {614.27} + {61.427} = {239.46}

{x + 724} + {61.427} = {239.46 + 614.27}

x + 785.427 = 853.73

x = 853.73 - 785.427

x = 68.303

Therefore, the previous balance in the account is equivalent to $68.303.

The system of equations can have an infinite number of solutions when the equations are equivalent.

A system of equations can have infinitely many solutions when the equations are equivalent, meaning that the equations are identical when one is subtracted from the other. When this happens, the system of equations is said to have an infinite number of solutions. To solve a system of equations by elimination with infinitely many solutions, the equations must first be rearranged so that the same variable terms are on one side and the constant terms are on the other. Then, the coefficients of one variable must be made equal by multiplying one or both equations by a constant. After this, the equations can be added together or subtracted from one another and the variable terms will cancel out. This will result in an equation with only the constant terms, which is equivalent to 0=0. This equation is true for all values of the variables, so the system of equations has an infinite number of solutions.

If a coin is flipped four times, find the probability distribution for the number of heads. The correct option is (c) is Chart C.

In probability theory and statistics, a probability distribution is a mathematical function that gives the probability of occurrence of various possible outcomes of an experiment. This is a mathematical description of a random phenomenon in terms of sample space and event probabilities (a subset of the sample space).

For example, if X is used to denote the result of a coin toss ("experimental"), the probability distribution of X gives the value 0.5 (1 to 2 or 1/2) for X = table. and assume that: 0, 5 for X = tail (assuming the coin is fair). Examples of random phenomena are the weather conditions at a later date, the height of a randomly selected person, the proportion of boys in a school, or the results of a survey being conducted.

General Properties of Probability Distributions

Statisticians call variables that follow probability distributions random variables. The notation for a random variable that follows a particular probability distribution function is

X usually represents a random variable.

Tilde (~) indicates follow distribution.

Upper case indicates distribution. B. N for normal distribution.

17297280 ways can the sites for the new stores be selected. This can be solved using the concept of probability.

The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

Given that,

14 different sites on which to locate 7 stores

For store 1, it can be placed on 14 sites.

Store 2 can be placed on 13 sites (since store 1 is already on site 1).

Store 3 can be placed on 12 sites and

so on until store 7 which has 8 sites.

Therefore the number of ways is:

C = 14 × 13 × 12 × 11 × 10 × 9 × 8

C = 17297280 ways

Step-by-step explanation:

1.

central (arc) angle is twice the inscribed angle (at the arc).

127° = 2A

angle A = 127/2 = 63.5°

2.

the full circle are 360°.

127° are arc angle CT, that leaves

360 - 127 = 233° for the arc angle C A T.

3.

the central angle at O opposite of the indicated 96° angle is (due to the rules of intersecting lines) also 96°.

the triangle M-O-A is an isoceles triangle (because both legs are a radius of the circle).

that makes angles A and M equally sized.

as the sum of all angles in a triangle is always 180°,

angle A = angle M = (180 - 96)/2 = 84/2 = 42°

4. see 3.

5.

the sum of all angles around one point on one side of a line is also always 180° (they represent a half-circle).

so, the top and the bottom angle at O are supplementary to the 96° angle (together they have 180°).

so, each is 180 - 96 = 84°

that means

arc angle M N A = 84 + 96 + 84 = 264°

6.

arc angle A F = 95°

arc angle A N = 103°

therefore, arc angle F N = 360 - 103 - 95 = 162°

as explained in 1.

angle A = arc angle F N/2 = 162/2 = 81°

7.

the triangles J-E-N and J-A-N have the same inscribed angle at the arc.

angle A = angle E (I cannot read the number at E).

8.

arc angle J A N + arc angle JN = 360

arc angle J N = 2× angle E

arc angle J A N = 360 - 2× angle E (again the number there is unreadable to me).

9.

again the inscribed angle at the arc is half of the opposite arc angle.

angle Y = arc angle T A / 2 = 70/2 = 35°.

10.

we have the arc angles S Y (134°) and T A (70°).

the 2 missing arc angles to make the whole circle are equally large due to T S and A T being equally long.

so,

arc angle S T = (360 - 134 - 70)/2 = 156/2 = 78°

Answer:

x = 1

y = -3

(1,-3)

Step-by-step explanation:

Set the 2 equations equal to each other and solve for x

-4x + 1 = 6x - 9   Add 4x from both sides

-4x  + 4x + 1 = 6x + 4x -9

1 = 10x - 9  Add 9 to both sides

1 + 9 = 10x - 9 + 9

10 = 10x  Divide both sides by 10

[tex]\frac{10}{10}[/tex] = [tex]\frac{10x}{10}[/tex]

1 = x

substitute 1 for x in either of the two original equations to solve for y

y = -4x + 1

y = -4(1) + 1

y = -4 + 1

y = -3

Check

y = -4x + 1

-3 = -4(1) + 1

-3 = -4 + 1

-3 = -3  Checks

y = 6x - 9

-3 = 6(1) - 9

-3 = 6 - 9

-3 = -3  Checks

The corporation will pay the bondholder a total of Php 1,200 + Php 2,000 = Php 3,200 over the life of the bond.

A bond's coupon is the annual interest payment that the bond issuer promises to pay to the bondholder. In this case, the bond has a face value of Php 2,000 and a 6% coupon, so the annual interest payment is 6% * Php 2,000 = Php 120.

The bond has a maturity date of 10 years, so the total interest payments to the bondholder over the life of the bond will be Php 120 * 10 = Php 1,200.

In addition to the interest payments, the bond issuer also promises to return the bondholder the face value of the bond at the maturity date. In this case, the face value of the bond is Php 2,000.

So, the corporation will pay the bondholder a total of Php 1,200 + Php 2,000 = Php 3,200 over the life of the bond.

The measure of angle ∠WDY is 89° in problem 20.

Two rays (half-lines) that share an endpoint make up an angle. The rays serve as the angle's sides, occasionally serving as the angle's legs and occasionally serving as its arms, while the latter is referred to as the vertex of the angle.

Two angles are said to be congruent by this definition if either of their vertex and side coordinates can be rigidly moved to coincide with the other. The angle may be written as AOB or BOA if O is the vertex and A and B are the points on the two sides (and this for any selection of the two points A and B.)

Given that D is the common point of line segments DW, DX and DY

m∠WDX = 2x - 5

m∠XDY = 52

m∠WDY = 5x - 16

to find m∠WDY

m∠WDY = m∠XDY + m∠WDX

5x - 16 = 52 + 2x - 5

5x - 2x = 52 - 5  + 16

3x = 63

x = 63/3

x = 21

m∠WDY = 5(21) - 16

m∠WDY = 89

Thus, the measure of angle ∠WDY is 89° in problem 20.

t = 4.9029 for Given the equation t = -0.0069d + 7.35, where t is the time of sunrise in hours after midnight and d is the number of the day in the year,

To find the time of sunrise on December 25th, the 359th day of the year, we need to substitute 359 for d in the equation.

t = -0.0069(359) + 7.35

t = -2.4471 + 7.35

t = 4.9029

This means that the time of sunrise on December 25th is 4.9029 hours after midnight. To convert this to minutes, we can multiply 4.9029 by 60 (since there are 60 minutes in an hour).

4.9029 x 60 = 294.174

So the sun rose on December 25th at 294.174 minutes after midnight, which is equivalent to 4 hours and 54 minutes (294 minutes) after midnight. To the nearest minute, the sun rose on December 25th at 4:54 AM.
