Either A or B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

(1.3^4 / 1.2^3)^7

1.2^ (3 · 7)  = 1.2^(21)

1.3 ^ (4 · 7) = 1.3^(28)

1.3^(28)/1.2^(21)

The degree of a polynomial is the highest power of the variable in the polynomial. In this case, the highest power of w is 3, so the degree of the polynomial is 3.

The leading coefficient of a polynomial is the coefficient of the term with the highest degree. In this case, the leading coefficient is 12.

In summary, the polynomial -9-8w+3w+12w³ has degree 3 and leading coefficient 12.

The true statements are

Consider the two points in the line

(-1, 1) and (3, 2)

The slope of the line = (2-1) / (3 -(-1))

= 1/4

The slope intercept form is

y = mx + b

2 = (1/4)3 + b

2 = 3/4 + b

b = 2 - (3/4)

b = 5/4

The equation of the line y = (1/4)x + 5/4

(3, 2) and (-1, 1) are points on the line

Consider the point (1, 3/2)

3/2 = (1/4)1 + 5/4

3/2 = 1/4 + 5/4

3/2 = 3/2

Therefore, (1, 3/2) is the solution of the line

It has infinitely many solutions

Therefore, the correct statements are statements A, B, C, E, F

Answer:

y = 3x + 37

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, 13 ) and (x₂, y₂ ) = (- 6, 19 )

m = [tex]\frac{19-13}{-6-(-8)}[/tex] = [tex]\frac{6}{-6+8}[/tex] = [tex]\frac{6}{2}[/tex] = 3 , then

y = 3x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (- 8, 13 ) , then

13 = 3(- 8) + c = -24 + c ( add 24 to both sides )

37 = c

y = 3x + 37 ← equation of line

For automobile traffic, dB=81.987657 dB.

For quiet conversation is 40.33423 dB.

For fender guitar, 115.56302 dB.

For jet engine, 151.98657 dB.

(A)

The intensity of automobile traffic is, I=1.58x10^8 I.

Given: dB=10 log (I/I0)

Substituting the value of I,

dB= 10 log (1.58x10^8 I/I)

=10 log (1.58x10^8)

Using the logarithm property,

=10 (log (1.58)+log (10^8))

=10 (log (1.58)+8 log (10)

=10( log (1.58)+8(1)

=80+1.98657

=81.98657

Thus, for automobile traffic, dB=81.987657 dB.

B)

Answer:

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

Step-by-step explanation:

To determine who wins the race, we need to first convert the given information into comparable units. The speed of Adil is given in kilometers per hour, while the time taken by Tom to complete the race is given in seconds. We can convert Adil's speed to meters per second by dividing by 3.6:

28.8 km/hr = 28.8 km/hr * (1 hour / 3600 seconds) * (1000 meters / 1 km)

         = 8 meters/second

We can then use this value to find the time it takes Adil to complete the race:

time = distance / speed

   = 200 meters / 8 meters/second

   = 25 seconds

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

As calculated from the data (1/6)² is the probability of getting 5 of same number on all the dice.

b.)If we will limit the number of winners then we will be able to provide them with large prizes and that also by taking moderate rate from everyone.

Actually, the likelihood of winning is closer to one-third (25/72).

Carnival game organizers want you to believe, like I did, that a game is fair so that you will participate.

The likelihood that you would win a game was just about 1/3, so you probably wouldn't squander your money.

Therefore,

The likelihood of getting five of the same number on all six dice is (1/6)².

Probabilities are mathematical representations of the likelihood that an event will occur or that a statement is true.

What is inequality?

The occurrence of an unfair and/or unequal distribution of opportunities and resources among the people that make up a society is referred to as inequality. To different people and in various settings, the word "inequality" may indicate different things.

Here,

Given

Josh is 4 years older than 2 times Kim's age.

The sum of their ages is less than 25.

We have to find the age of Kim.

Let Kim's age be x.

Then Josh's age is (2x+4)

Applying central limit theorem number of books reads in one full year is equal to 720.

As given in the question,

Let X be the number of magazine read by Charlie.

Number of days in 12 months consider 30 days in each month 'n'

= 12 × 30

= 360 days

Number of magazine lies between 3500 and 3600

Consider μ = 2 and σ = √2

Central limit theorem , we have

z =( [tex]\bar{X}[/tex] - μ )/ σ/√n

[tex]\bar{X}[/tex] = X / n

Probability of total number of magazine reads between ( 3500 to 3600)

= P ( 3500 ≤ X ≤ 3600 )

= P( 3500/360 ≤ X/ n ≤3600/360)

= P( 9.72< X/n≤ 10 )

= P [ (9.72 - 2)/ √2/√360 ≤ ( X/n - μ)/σ/√n ≤(10 - 2)/ √2/√360]

= P(130.2 ≤ Z ≤107.4)

= P( 0≤Z≤107.4) - P (0≤Z≤130.2)

= φ( 130.2) + φ(107.4)

= 1 + 1      { φ(a) = 1 , a>1}

= 2

Number of books Charlie reads in one year =

∑2ₙ where n = 1 to 360

True, the graphical solution method of linear programming employs the corner point method to find the optimal solution.

The most straightforward method of problem optimization is linear programming. We can turn a real-world issue into a mathematical model using this approach. Linear programming can be used to handle a wide range of issues in many different fields, although it is typically applied to issues where the goal is to maximize profit, cut costs, or use resources as sparingly as possible.

Explanation:

The corner point method of graphical linear programming involves plotting the linear equations representing the constraints of the problem onto a graph and then finding the points of intersection of the equations. These points of intersection are called the corner points, and the optimal solution will be located at the corner point that produces the greatest value.

Answer: Luisa is correct.

Step-by-step explanation: Luisa is correct. To find the solution to the equation, we need to isolate the radical expression on one side of the equation. If we subtract x from both sides, we get √5 + 4x - x = x - x, or √5 = 0. Since the square root of any number is always positive, this equation has no solution. Therefore, the solution is H = 5.

On the other hand, if we square both sides of the equation, we get 5 + 8x + 4x^2 = x^2. If we simplify this equation, we get x^2 + 8x - 5 = 0. This equation can be solved using the quadratic formula, which gives us x = (-8 +/- sqrt(64 + 20))/2. This simplifies to x = (-8 +/- sqrt(84))/2. The solutions to this equation are x = -1 and x = 5. However, since we squared both sides of the original equation, we have to check whether these solutions actually work in the original equation. Substituting x = -1 into the original equation gives us √5 + 4(-1) = -1, or √5 = -1. This is not a valid solution, since the square root of any number is always positive. However, substituting x = 5 into the original equation gives us √5 + 4(5) = 5, or √5 = 0. This is a valid solution, since the square root of any number is always positive. Therefore, the only solution to the original equation is x = 5, which is the solution that Luisa found.
