The probability that exactly 4 of the 8 diamonds picked from the bag are real diamonds is 28/256 or 11.1%.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 meaning the event is impossible and 1 meaning the event is certain to occur. Probability theory is used to make predictions and calculate the chances of different outcomes in order to make decisions. Probability theory can also be applied to understand the behavior of complex systems.

This is calculated by first determining the total amount of possible outcomes. Out of the 8 diamonds picked, there are 8C4 = 70 ways in which the 4 real diamonds can be chosen. With 8 real diamonds and 7 fake diamonds, the probability of a real diamond being chosen is 8/15, and the probability of a fake diamond being chosen is 7/15. Therefore, the probability of having exactly 4 real diamonds is 70 x (8/15)^4 x (7/15)^4 = 28/256.

The domain of a function is the set of all possible input values (x-values) for which the function produces a valid output (y-value). The range of a function is the set of all possible output values (y-values) that the function can produce.

When working with inequalities, the domain and range can be found by analyzing the inequality and the context of the problem.

To find the domain of an inequality function, we need to identify any restrictions or limitations on the input values (x-values) that would make the inequality invalid.

For example, if the inequality contains a denominator that cannot be equal to zero, we need to exclude those values of x from the domain.

To find the range of an inequality function, we need to identify the set of all possible output values (y-values) that would make the inequality true.

For example, if the inequality is in the form y > x, we know that all values of y that are greater than x will satisfy the inequality.

In summary, finding the domain and range of inequalities of a function involves identifying any restrictions or limitations on input values and the set of possible output values that would make the inequality true.

Step-by-step explanation:

We have our equations. So, we will substitute them in our last equation, giving us:

[tex](x + 1) * (x^{2} + 2x - 1) + 2x[/tex]

Opening the parentheses gives us:

The equation representing the polynomials are D = x³ + 3x² + 3x - 1

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as D

Now , the value of D is

Substituting the values in the equation , we get

A = x + 1

B = x² + 2x - 1

C = 2x

The value of AB + C = D

And , AB = ( x + 1 ) ( x² + 2x - 1 )

On simplifying the equation , we get

AB = x ( x² + 2x - 1 ) +  ( x² + 2x - 1 )

AB = x³ + 2x² - x + x² + 2x - 1

AB = x³ + 3x² + x - 1

And , D = x³ + 3x² + x - 1 + 2x

D = x³ + 3x² + 3x - 1

Answer:

b = 4+15

b =19

Step-by-step explanation:

5x^2 + bx + 12 = 0

the sum of its roots = –b/a

m + n = - b/a

-4/5 + n = -b/5

-4 + 5n = -b

5n= -b + 4 -------------1

product of its roots = c/a

m*n = c/a

-4/5 * n = 12/5

-4 n = 12

n = -3 is the other root -------------2

Plug-in equation 2 in 1

5(-3) = -b + 4

-15 = -b + 4

b = 4+15

b =19

One of the solutions to the equation 5x^2+bx+12=0 is -4/5.the other solution is 2.4 + (-4/5) = 2.

The other solution to the equation 5x^2+bx+12=0 can be found by using the fact that the solutions of a quadratic equation of the form ax^2+bx+c=0 are given by the formula: x = (-b ± √(b^2-4ac)) / 2a.

In this case, a=5, b=b and c=12. We know that the product of the roots is equal to c/a and sum of roots is equal to -b/a. so the product of the roots is 12/5 = 2.4and the sum of the roots is -b/5 .

since we know that one of the solutions is -4/5, we can find the other solution by using the above formulas: -4/5 = 2.4 - other solution so the other solution is 2.4 + (-4/5) = 2.

The fundamental theorem of algebra any polynomial was first proved by Carl Friedrich Gauss in 1799.

In 1799, Carl Friedrich Gauss was a German mathematician who proved that any polynomial equation with complex coefficients has at least one root in the complex plane. This is known today as the Fundamental Theorem of Algebra. Gauss started by examining a particular polynomial equation and then used his knowledge of the properties of polynomial functions to prove that any polynomial equation with complex coefficients must have at least one complex root. His proof used a combination of calculus and algebraic manipulations to establish that the coefficients of a polynomial equation must satisfy certain conditions in order for the equation to have a complex root. Once these conditions are satisfied, he showed that the equation must have at least one complex root.

According to the graph the distance from A to B is horizontal, so it need not be counted.

From B to C the distance is = 3 units

Again from C to O the distance is horizontal, so it need not be counted.

From O to D the distance is = 10 units

From D to E the distance is = 4 units

From E to F the distance is horizontal, so it need not be counted.

The distance from F to N need not be counted as it will be the repetition of the total height.

Answer: The perimeter of the shape is approximately 18.0 feet.

Step-by-step explanation:

The shape you described is a triangle, with one side of 8 feet and two sides of 5 feet. To find the perimeter of a triangle, we add up all the side lengths:

Perimeter = 8' + 5' + 5'

Perimeter = 8' + 10'

Perimeter = 18'

Rounding to the nearest tenth:

18 feet is the same as 18.0 feet rounded to the nearest tenth.

So, the perimeter of the shape is approximately 18.0 feet.

Car Y offers you more mileage than Car X per gallon.

The mileage of a vehicle is the number of miles that it can travel using one gallon or litre of fuel or gasoline.

To find the mileage per gallon, we find the distance that each car can travel using 1 gallon of gasoline.

For Car X,

Mileage = No. of miles/No. of gallons

= 120/11 = 10.909

For Car Y,

Mileage = No. of miles/No. of gallons

= 100/9 = 11. 11

Therefore, marginally, Car Y has the better mileage.
