Area is calculated by multiplying the length of a shape by its width.

Step-by-step explanation:

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. Take a pencil and draw a square on a piece of paper. It is a 2-D figure. The space the shape takes up on the paper is called its Area.

The probability that the mean number of lightning strikes per square kilometer is less than 5 is 0.0016, when  open ground in a year has mean 6 and standard deviation 2.4.

It imply a quantity that falls somewhere between the values of the extreme members of a set in mathematics. There are different types of means, and how they are calculated relies on the relationship that is known about or is regarded as governing the other members.

Given,

Mean = 6

Standard deviation = 2.4

The value that has been reduced by the population mean and divided by the standard deviation is called the z-value.

z = x - mean/ standard deviation/√n

z = 5 - 6/2.4/√50

z = - 2.95

Using table A, calculate the corresponding probability;

= P(x <5)

= P( z < -2.95)

= 0.0016

The probability that the mean number of lightning strikes per square kilometer is less than 5 is 0.0016.

Answer:

his gives us that Chris is walking 69 feet per minute faster than Heidi.

Step-by-step explanation:

1 mile is equal to 5,280 feet, we can multiply 3 by 5,280 to find that Heidi is walking 15,840 feet per hour.

Next, we need to convert both speeds to feet per minute. Since there are 60 minutes in an hour, we can divide both speeds by 60 to convert them to feet per minute. This gives us that Heidi is walking 264 feet per minute and Chris is walking 333 feet per minute.

Finally, to find out how much faster Chris is walking than Heidi, we can subtract Heidi's speed in feet per minute from Chris's speed in feet per minute.

Jasmine sold the fidget spinner to Bryan for the cost of $5.55.

To find the cost that Jasmine sold the fidget spinner to Bryan for, we need to first find the amount of the markup by multiplying the original price by the markup percentage.

As per the question, the original price of the fidget spinner is $3, and the markup percentage is 850%, so the markup amount is :

$3 × 850% = $2.55.

Next, we need to add the markup amount to the original price to find the selling price. So, the selling price is :

$3 + $2.55 = $5.55.

Therefore, Bryan paid $5.55 for the fidget spinner that Jasmine had just sold him.

Answer:

A. One Solution

Step-by-step explanation:

To determine if a system of equations has no solutions, infinitely many solutions, or exactly one solution, we can solve the system by any method, such as elimination or substitution.

In this case, we can solve the system by elimination. Multiplying the first equation by -2 and adding it to the second equation, we get:

0x + 4y = -3

This equation tells us that y must be equal to -3/4, but we still need to check if this value of y satisfies the original equations. Substituting -3/4 for y in the first equation, we get:

2x + (-3/4) = 7

Solving this equation for x, we get x = 5/4. Substituting this value of x and -3/4 for y in the second equation, we get:

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

which simplifies to:

-5/2 + (-3/2) = -5

This equation is true, so the solution of the system is x = 5/4 and y = -3/4. Since the system has a unique solution, the answer is (A) One Solution.

Answer:

To find the asymptotes and the end behavior of the function f(x) = 4x / (x-16), we can first divide both the numerator and denominator by the highest common factor of 4x and (x-16). This gives us:

f(x) = (4x / 4x) / ((x-16) / 4x)

= 1 / ((x-16) / 4x)

Next, we can find the horizontal asymptotes by looking at the values of the function as x approaches positive and negative infinity. When x approaches positive infinity, the denominator of the function approaches 0, so the function approaches 1 / 0, which is undefined. Therefore, the function does not have a horizontal asymptote as x approaches positive infinity.

When x approaches negative infinity, the denominator of the function approaches -16 / -infinity, which is 0. Therefore, the function approaches 1 / 0, which is undefined. Therefore, the function does not have a horizontal asymptote as x approaches negative infinity.

Next, we can find the vertical asymptotes by setting the denominator of the function equal to 0 and solving for x. In this case, the denominator is (x-16) / 4x, so we can set each factor equal to 0 and solve for x:

x-16 = 0

x = 16

4x = 0

x = 0

Therefore, the function has two vertical asymptotes at x = 0 and x = 16.

Step-by-step explanation:

After solving we can conclude that (c) f(x) = -x is an odd function.

If -f(x) = f(-x), then a function f is said to be odd for all values of x.

When taking into account additive inverses, the functions even and odd are those that satisfy particular symmetry relations.

They are crucial to understanding power, the Fourier series, and mathematical analysis.

So, (a) f(x) = x³ + 5x² + x:

f(-x) = (-x)³ + 5(-x)² + (-x)

      = -x³ + 5x² - x

      = -(x³ - 5x² + x)

Neither even nor odd describe the function.

(b) f(x) = x² + x

f(-x) = (-x)² + (-x)

       = -(-x² + x)

Neither even nor odd describe the function.

(c) f(x) = -x

f(-x) = -(-x)

      = x

      = -f(x)

f(-x) = -f(x) makes the function odd.

Therefore, after solving we can conclude that (c) f(x) = -x is an odd function.

The sequence's average difference is 12.5.

According to the given information

The sum of an arithmetic sequence's second and third terms is 27.

The combination of the fourth and fifth terms is 77.

We must ascertain,

Let d represent the sequence's common difference.

The arithmetic series' second term is,

Second term = a + d

The arithmetic series' third term is as follows:

Third term = a + 2d

The second and third terms in the sequence add up to 27, thus.

Second term + third term = 27

a + d  + a + 2d  = 27

2a + 3d = 27

The arithmetic series' fourth term is,

Fourth term = a + 3d

The fifth term in the mathematical series is as follows:

Fifth term = a + 4d

The sequence's fourth and fifth terms add up to 77

Fourth term + fifth term = 77

a + 3d + a + 4d = 77

2a + 7d = 77

After resolving the two equations,

2a + 3d = 27

2a + 7d = 77

Subtracting both the equations

2a + 3d - ( 2a + 7d ) = 27 - 77

2a + 3d - 2a - 7d = -50

An equation is a formula that expresses equality by connecting two expressions with an equal sign '='. Equations and their cousins ​​in other languages ​​may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, but in English any formula in its proper form consisting of two equations joined by an equal sign is an equation.

The equation resembles a weighted scale. When two bowls have the same weight (such as grain), the two weights balance the scale and are said to be equal. If you remove a certain amount of grain from one pan of the scale, you must remove the same amount of grain from the other pan to keep the scale balanced. More generally, the equation remains in equilibrium if the same operation is performed on both sides.

The other two roots of the polynomial are x = (7 + √33)/4 and x = (7 - √33)/4.

A polynomial is an expression of one or more algebraic terms, each of which is composed of constants and/or variables raised to non-negative integer powers. A polynomial can be written in the form of an equation, where the coefficients of the terms form a sequence of numbers. Polynomials can also be expressed using a factored form, in which each of the terms is the product of a coefficient and a single variable or factor. Polynomials are commonly used to model real-world phenomena, such as the behavior of a system or process. The degree of a polynomial, which is the highest degree of the terms, determines the number of solutions it has. For example, a polynomial of degree two has two solutions while a polynomial of degree three has three solutions. The solutions of a polynomial are determined by solving the equation formed by the polynomial's terms.

Let us first rewrite the polynomial in a standard form:

2x^3 + 7x^2 + ax + 2 = 0
We can factor this polynomial using the Factor Theorem. The Factor Theorem states that if a is a root of a polynomial, then x-a is a factor of the polynomial.
Since x=-2 is a root of the polynomial, the factor (x+2) must be a factor of the polynomial.
Therefore, we can rewrite the polynomial as:
2x^3 + 7x^2 + ax + 2 = 2(x+2)(x^2 + bx + c)
Now, we can use the coefficients of the polynomial to solve for a, b and c.
Comparing the coefficients of the polynomial on both sides:
2 = 2c
7 = b
a = -2b-4c
Substituting the values of c and b in the equation for a, we get:
a = -2(b) - 4(2)
 = -2(7) - 8
 = -16
Therefore, the value of a is -16.
To find the other roots of the polynomial, we just need to solve the remaining factor (x^2 + bx + c) = 0.
Substituting the values of b and c, we get:
x^2 + 7x + 2 = 0
We can solve this equation using the Quadratic Formula:
x = [-b ± √(b^2 - 4ac)]/2a

Substituting the values of a, b and c, we get:
x = [-7 ± √(7^2 - 4(2)(2))]/2(-2)
 = [-7 ± √(49 - 16)]/-4
 = [-7 ± √33]/-4
Therefore, the other two roots of the polynomial are x = (7 + √33)/4 and x = (7 - √33)/4.

The amount of money the carnival committee should expect to pay for prizes for the booth is 218.7 dollars.

Therefore, the answer is option C.

At a booth at the school carnival in past years, they've found that 22% of students win a stuffed toy ($3.60), 16% of students win a jump rope ($1.20), and 6% of students win a t-shirt ($7.90). The remaining students do not win a prize.

If 150 students play the game at the booth, the amount of money the carnival committee expect to pay for the prizes of the booth is as follows:

total student that partake = 150

number that win stuffed toy  = 22% of 150

number that win stuffed toy = 33

number that win  jump rope = 16% of 150

number that win  jump rope = 24

number that win  t-shirt = 6% of 150

number that win  t-shirt = 9

Therefore,

prizes for those that win stuffed toy = 33 × 3.60 = 118.8 dollars

prizes for those that win jump rope = 24 × 1.20 = 28.8 dollars

prizes for those that win t-shirt = 9 × 7.90 = 71.1 dollars

Hence,

total amount the committee is expected to pay for prizes = 118.8 + 28.8 + 71.1 = 218.7 dollars
