Study the following data set.

{8,15,9,18,9,17,22,10,11,9,13}

What is the quarterfinal range of the data set?

Answer:

So the solution is x = -0.57 and y = 30/7.

Step By Step Explanation:

To solve a system of linear equations, such as "x = 8 - 2y" and "3x + y = 6", we can use substitution or elimination method.

Using substitution method:

solve one equation for one variable

substitute the expression obtained in step 1 into the second equation

solve the equation obtained in step 2 to find the value of the variable that was solved for

substitute this value back into the first equation to find the value of the other variable.

x = 8 - 2y;

3x + y = 6;

solve for x in the first equation

x = 8 - 2y

substitute the value of x in the second equation

3(8-2y) + y = 6

solve the second equation obtained for y

24 - 6y + y = 6

25 - 6y = 6

-6y = -19

y = 19/6

substitute the value of y back in the first equation

x = 8 - 2(19/6) = 8 - (38/6) = 8 - (63/6) = 8 - (63/6) = 8 - 10.5 = -2.5

So the solution is x = -2.5 and y = 19/6

Alternatively, using elimination method:

Add or subtract one equation from the other to eliminate one of the variables.

Solve the resulting equation for the remaining variable.

Substitute this value into either of the original equations to find the value of the eliminated variable.

Multiply the first equation by -3

-3x = -24 + 6y;

Add the above equation to the second equation

-3x + y = 6

-24 + 6y + y = 6

-24 + 7y = 6

7y = 30

y = 30/7

substitute the value of y into the first equation

x = 8 - 2(30/7) = 8 - (60/7) = 8 - (60/7) = 8 - 8.57 = -0.57

So the solution is x = -0.57 and y = 30/7.

When the capacity and radius are stated as 37.68 cubic inches and 1.5 inches, respectively, the height of the soup can is 5.34 inches.

It is also known as the object's capacity. The fundamental equation for volume is length, width, and height, as opposed to the fundamental equation for the area of a rectangular shape, which is length, breadth, and height. The math is the same regardless of how you refer to the different dimensions. For example, you can substitute "depth" for "height." Volume is used to describe an object's capacity.Volume can also be used to describe how much space a three-dimensional object occupies.

The correct equation to find the amount, in dollars, x, of check 353 is:

D. 1,460.89 +25.79+ x = 1,536.71

This equation shows that the sum of check 354, check 353, and the known total of 1,460.89 is equal to the corrected total of 1,536.71. So by solving for x, you can find the amount of check 353.

To solve for x, you would subtract 25.79 and 1,460.89 from both sides of the equation:

x = 1,536.71 - 1,460.89 - 25.79

x = 50.03

So the amount of check 353 is $50.03

Answer:

x=18

Step-by-step explanation:

We know that triangle ABC is similar to triangle ADE, so therefore the proportions of their corresponding sides must be congruent.

We know that all of AD is 15 and BD is 5, which leaves AB to be equal to 10.

Next, we set up the following proportion: 10/12 = 15/x because they are corresponding sides of similar triangles divided by eachother.

Cross multiply and you will get 10x = 12x15 (180)

next, divide both sides by 10 to isolate x

x = 18

The sum of the measures of the interior angles of a quadrilateral is 360°. The sum of the measures of the exterior angles of a quadrilateral is 360°.

What is a quadrilateral?

A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.

Assume that ABCD is a quadrilateral.

The sum of the interior angle and the corresponding exterior angle is 180°.

The exterior angle of A is E. The exterior angle of B is F. The exterior angle of C is G. The exterior angle of D is H.

Thus ∠A + ∠E = 180°  .....(i)

∠B + ∠F = 180°  ......(ii)

∠C + ∠G = 180° ......(iii)

∠D + ∠H = 180° ......(iv)

Add equations (i), (ii), (iii), (iv):

∠A + ∠E + ∠B + ∠F + ∠C + ∠G +  ∠D + ∠H = 180°+180°+180°+180°

(∠A+∠B + ∠C +∠D) + ∠E +∠F +  ∠G + ∠H = 720°

The sum of all interior angles of quadrilateral is ∠A+∠B + ∠C +∠D = 360°.

360°+  ∠E +∠F +  ∠G + ∠H = 720°

∠E +∠F +  ∠G + ∠H = 720° - 360°

∠E +∠F +  ∠G + ∠H =  360°

The value of A when x - 5 is a factor of x³ - 3x² + ax - 10 is -8.

A polynomial factor is a polynomial that divides another polynomial exactly, with no remainder.

For example, if we have a polynomial P(x) = x³ - 3x² + ax - 10, and we have a polynomial factor F(x) = x - 5, we can say that P(x) is divisible by F(x) with no remainder.

In general, a polynomial of degree n has n roots (or zeroes) and the factorization of polynomial can be expressed as a product of its roots and its corresponding multiplicity.

To find the value of A, set x = 5 in the equation x³ - 3x² + ax - 10 and solve for A that will make the equation equal to zero..

So when x = 5, we have:

x³ - 3x² + ax - 10 = 0

(5)³ - 3(5)² + a(5) - 10 = 0

125 - 75 + 5a - 10 = 0

5a = -40

a = -8

Hence, if x - 5 is a factor of x³ - 3x² + ax - 10, then A is equal to -8.

What is the graph of a function?

The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.

The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.

i) 2y - 4x < 8 can be solved by adding 4x to both sides and then dividing by 2, giving:

y < 2x + 4.

ii) -4y > -x + 12 can be solved by adding x to both sides and then dividing by -4, giving: y < x/4 - 3.

iii) | x + 3 | = y, you can split this into two cases:

i. x + 3 = y

ii. -(x + 3) = y

iv) |2x – 6| + 2 = y, you can split this into two cases:

i. 2x - 6 + 2 = y

ii. -(2x - 6) + 2 = y

We can use these equations to plot the graph on a coordinate plane.

Hence, the solution is the set of all points (x,y) that satisfy the inequalities:

y < 2x + 4,  y < x/4 - 3, x + 3 = y, and 2x - 6 + 2 = y.

The common ratio is 18/23.

What is the geometric sequence?

A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a fixed number, called the common ratio. To find the common ratio of a geometric sequence, we can divide each term by the previous term.

It's important to note that in a geometric sequence, the quotient of any two consecutive terms is always constant and that is the common ratio.

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is.

aₙ= a₁ rⁿ⁻1. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.

Given the geometric sequence: 28, 23, 18

We can find the common ratio by dividing each term by the previous term:

r = 23/28 = 18/23

Therefore, the common ratio is 18/23.

If there were only 5 coin tosses, the answer would be p5, where p= 0.6.

Now,

18 - 5 + 1 = 14 consecutive sequences of 5 flips contained in 18 flips. So it's tempting to say the answer is 14p5 ≈ 1.08, but it's also wrong. This is actually the number of expected 5-sticks, not the probability of at least one 5-stick. The problem is that since these sequences overlap, the events are not mutually exclusive, so we cannot sum them to get the overall probability. We have to subtract out all the possibilities of generating multiple 5 streaks, but calculating that probability is very complicated.

This post on stack swapping suggests an elegant approach that can be adapted to this problem. Let's define a sequence P(n). where P(n) is the probability of at least one consecutive heads after a total of n rollovers. So the answer of the question is P(18).

Clearly, P(0) = P(1) = P(2) = P(3) = P(4) = 0. This is because he can't get 5 heads in a row unless he flips the coin 5 times. P(5) is easy to compute, it only happens if all 5 flips are heads, so P(5) = p5 = 2433125 = 0.07776 .

Well, the length of the discontinuous part is n - 6, so the probability is

(1 −P(n−6)). The T,H,H,H,H,H part is the probability (1−p)p5 =(0,4)(0,6)5, and since these are independent events, the probability of THHHHH [not consecutive first letters] is (1−P( n −6))( 1−p) p5 .

P(n) = P(n−1) + (1−P(n−6))(1−p) p5.

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal symbol (). Different inequalities are used to contrast values, no matter how small or large. Many simple inequalities can be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

An equation is an expression relating two or more numbers and variables.

The standard form of an equation is:

y = mx + b

Where m is the rate of change(slope) and b is the y intercept.

The first equation:

y = -4x + 8

Both equations intersect at a point with y -coordinate 4. Hence the corresponding x coordinate is by substituting y= 4:
