The probability that 4 prefers A, 1 prefer B and 5 will have no preference = 0.0024

Here, in a certain town, 40% of the eligible voters prefer candidate a,

⇒ P(A) = 40%

⇒ P(A) = 0.4

10% prefer candidate b,

⇒ P(B) = 10%

⇒ P(B) = 0.1

and the remaining 50% have no preference.

⇒ P(T) = 50%

⇒ P(T) = 0.5

Also, the sample size = 10

So, the probability that 4 prefers A, 1 prefer B and 5 will have no preference would be:

P = ⁵C₄ (0.4)⁴ × ⁶C₁ (0.1) × (0.5)⁵

P = 0.0024

We can conclude after answering the provided question that In order to slope make at least $225.00 in sales, we must solve for m:

[tex]s = 75m + 1500 225 = 75m + 1500\s75m = -1275\sm = -17[/tex]

Slope is the downward movement of a near - constant basis in mathematics. It is a test of how much the y-value of an activity appears to vary when the x-value changes. The curve of a line is ordinarily indicated by the letter m and can be determined using the equation: m = (y2 - y1) / (x2 - x1) (x1, y1) and (x2, y2) are any 2 things on the line. A line's slope can be positive, negative, zero, or unknown. A positive slope indicates that the line moves up from left to right, whereas a decreasing trend indicates that the line descends from left to right.

a. Because the relationship between the two variables is proportional, the function that connects the sales (s) and the number of muffins (m) is a linear function. The slope of the line can be calculated by dividing the change in sales by the change in the number of muffins:

slope = (2400 - 1800) / (12 - 4) = 600 / 8 = 75

The equation line is as follows:

s = 75m + b

To find the y-intercept (b), we can substitute one of the data points:

[tex]1800 = 75(4) + b\sb = 1800 - 300\sb = 1500[/tex]

As a result, the function that connects sales and the number of muffins is:

s = 75m + 1500

b. In order to make at least $225.00 in sales, we must solve for m:

[tex]s = 75m + 1500 225 = 75m + 1500\s75m = -1275\sm = -17[/tex]

Answer:

area = 288.62 mm²

Step-by-step explanation:

To find the area we divide the complex shape into simple shapes whose areas we can find.

There is a rectangle in the center.

There are 2 congruent triangles on the sides.

We have the lengths of 2 perpendicular sides of the triangles, so they are the base and height.

For the rectangle, we only have the width. We need to find the length.

The length of the rectangle is the hypotenuse of the triangles.

We use the Pythagorean theorem to find the length of the hypotenuse of the right triangle. That is the length of the rectangle.

a² + b² = c²

(10.4 mm)² + (15.3 mm)² = c²

c² = 342.25 mm²

c = 18.5 mm

area = area of triangles + area of rectangle

area = 2 × (1/2)bh + LW

area = 2 × (1/2) × 15.3 mm × 10.4 mm + 18.5 mm × 7 mm

area = 159.12 mm² + 129.5 mm²

area = 288.62 mm²

Performing an elementary row operation on a matrix does not change its determinant.

An elementary row operation is a transformation of a matrix that involves interchanging two rows, multiplying a row by a nonzero scalar, or adding a scalar multiple of one row to another row.

Let A be a matrix and let B be the matrix obtained from A by performing an elementary row operation. We want to show that det(A) = det(B).

If the row operation involves interchanging two rows, then the determinant of the resulting matrix is the negative of the determinant of the original matrix.

If the row operation involves multiplying a row by a nonzero scalar, then the determinant of the resulting matrix is the scalar multiplied by the determinant of the original matrix.

If the row operation involves adding a scalar multiple of one row to another row, then the determinant of the resulting matrix is the same as the determinant of the original matrix.

In any case, the determinant of the matrix is preserved under elementary row operations. Therefore, performing an elementary row operation on a matrix does not change its determinant.

Yes, it is necessarily  true that W(orthogonal complement) = span(v k+1,......,vn)

Since {v1,....,vn} is an othogonal basis for R^n, each vector in the basis is orthogonal to every other vector in the basis. Therefore, the vectors v1,....,vk are orthogonal to the vectors vk+1,....,vn, and vice versa. This means that any vector in W is orthogonal to any vector in span(vk+1,...,vn). Hence, W and span(vk+1,...,vn) are orthogonal complements of each other.

To show that W(orthogonal complement) = span(vk+1,...,vn), we need to show that any vector in W(orthogonal complement) is also in span(vk+1,...,vn) and vice versa.

et x be a vector in W(orthogonal complement). Then, x is orthogonal to every vector in W, which means x is orthogonal to v1,....,vk. Since {v1,....,vn} is a basis for R^n, any vector in R^n can be written as a linear combination of the basis vectors.

Therefore, we can write x as a linear combination of v k+1,......,vn. This shows that x is in span(vk+1,...,vn).

Conversely, let y be a vector in span(vk+1,...,vn). Then, we can write y as a linear combination of v k+1,......,vn. Since v1,....,vk are orthogonal to v k+1,......,vn, we have y is orthogonal to v1,....,vk. Therefore, y is in W(orthogonal complement).

Commutative property of addition.

Step-by-step explanation:

The given expression is:

x + y + z = z + y + x

To match the example with the corresponding property, we need to simplify the expression using the commutative property of addition.

According to the commutative property of addition, the order of the terms in an addition expression does not affect its value. That is:

a + b = b + a

Using this property, we can rewrite the given expression as:

x + y + z = x + y + z

we see that both sides of the equation are identical. This means that the expression is true, regardless of the values of x, y, and z.

Therefore, the example "x + y + z = z + y + x" matches with the commutative property of addition.

To find the maximum gas mileage, we need to find the vertex of the parabola representing the gas mileage function.

The x-coordinate of the vertex of a parabola in the form of y = ax^2 + bx + c is given by -b/2a.

In this case, the gas mileage function is m(x) = -0.026x^2 + 2.593x - 35.023, so a = -0.026 and b = 2.593.

The x-coordinate of the vertex is therefore:

x = -b/2a = -2.593/(2*(-0.026)) = 49.9 (rounded to one decimal place)

This means that the maximum gas mileage occurs at a speed of 49.9 mph.

To find the maximum gas mileage, we can substitute x = 49.9 into the gas mileage function:

m(49.9) = -0.026(49.9)^2 + 2.593(49.9) - 35.023 ≈ 36.1 mpg

Therefore, the maximum gas mileage is approximately 36.1 mpg.

For given expression e will be 7/3.

What exactly are expressions?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations that can be evaluated to produce a single value.

Expressions can be simple or complex, and they can involve arithmetic operations such as addition, subtraction, multiplication, and division, as well as more advanced operations such as exponents, logarithms, and trigonometric functions.

Now,

We can solve for e by setting the given value of f equal to 49 and then solving for e.

f = 9e²

When f = 49, we have:

49 = 9e²

Dividing both sides by 9, we get:

49/9 = e²

Taking the square root of both sides, we get:

±√(49/9) = ±(7/3) = e

So the solutions for e are e = 7/3 or e = -7/3. However, since e is a measure of distance and cannot be negative, the only valid solution is e = 7/3.

1369-1225=c²

144=c²

√144=√c²

12=c

c=12

Step-by-step explanation:

Use the Pythagoras threom. It's formula is a²=b²+c² where a=37, b=35 and c=?

Therefore, the dimensions of triangle ABC and the angles opposite to these sides are:

a ≈ 6.85 units

b = 13 units

c ≈ 9.39 units

A ≈ 40 degrees

B = 97 degrees

C = 43 degrees

A triangle is a geometrical shape that has three sides and three angles. It is formed by connecting three non-collinear points in a plane with straight line segments. The three sides may have different lengths, and the three angles may have different measures. The sum of the angles in a triangle is always 180 degrees. Triangles are used in many fields of mathematics, as well as in science, engineering, and everyday life. They can be classified by their side lengths and angle measures, and there are various formulas and theorems that apply to triangles.

Here,

We can use the Law of Sines to find the missing measures of the triangle.

Recall that the Law of Sines states that for any triangle ABC:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite to the angles A, B, and C, respectively.

Given that b=13 units, and angle B=97 degrees, we can set up the proportion:

13/sin(97) = c/sin(43)

Solving for c, we get:

c = (13*sin(43))/sin(97) ≈ 9.39

Now, to find the remaining angle and side, we can use the fact that the angles of a triangle sum up to 180 degrees. We know that angle C is 43 degrees, so we can find angle A as:

A = 180 - 97 - 43 = 40 degrees

And we can find side a using the Law of Sines:

a/sin(40) = 13/sin(97)

Solving for a, we get:

a = (13*sin(40))/sin(97) ≈ 6.85

In mathematics, an equation is a proposition that states the equivalence of two expressions. An equation consists of two sides separated by a system of equations (=). For instance, the statement "2x + 3 = 9" states that the word "2x Plus 3" equals the integer "9". The goal of solving equations is to find the value or amounts of the variable in the model) that will permit the calculation to be accurate. Mathematics can be simple or complex, linear or nonlinear, and contain one or more parts. For example, in the equation "x2 + 2x - 3 = 0," the variable x is raised to the power of 2. Lines are used in many areas of mathematics, including algebra, arithmetic, and geometry.

Let the original price of the motorcycle be P.

Depreciation per year = 4% of P = 0.04P

Cost of motorcycle after 3 years = P - 3(0.04P) = P - 0.12P = 0.88P

√87x = √(x * 87) = √(x * 3 * 29)

If x is a perfect square, say x = a^2, then we can rewrite the expression as:

√(a^2 * 3 * 29) = a√(3 * 29)

In this form, the expression is simplified further, because a is a constant and √(3 * 29) is a simplified radical.

The expression √87x cannot be further simplified because the square root and the variable are multiplied together. However, it is possible that the expression was meant to be written as √(87x) with the entire expression under the square root symbol. In this case, the expression can be further simplified by evaluating the square root of 87 times x, but the value of x is not relevant to this simplification.

Solving the proportion, the smallest amount of this green paint that he must throw away so that, using the rest of his green paint and some extra blue and/or yellow paint, he could make 4.08 liters of paint of the correct shade of green is    5 liters.

Let's assume the amount of green paint to be thrown away is x liters. Since, 5 liters of green paint (the correct shade of green) is required then the proportion can be expressed as

2 liters of blue paint: 3 liters of yellow pain

The sum of blue and yellow paint is 5 - x liters

Then,0.4 = 2/5 + a/(5 - x)

where,  "a" is the amount of blue paint to be added to the 3 liters of yellow paint

0.4(5 - x) = 2 + 5a-2 = 2.6x - 5a

0.6 = 2.6x - 5a

Since the least amount of green paint should be thrown away to make the correct shade of green paint, the minimum value of x should be found.

0.6 = 2.6x - 5a

0.6 + 5a = 2.6x

5a = 2.6x - 0.6a = (2.6/5)x - 0.12a = 0.52 - 0.12a

To minimize the value of x, a should be maximized. The maximum value of a is 2 (two liters) since there are only 3 liters of yellow paint.

Using a=2 (two liters), the value of x is:

a = (2.6/5)x - 0.12a = (2.6/5)x - 0.12 (2)2 = (2.6/5)x - 0.24x = 5(2 + 0.24)/2.6x = 4.08

What is the natural logarithm?

The natural logarithm, denoted by ln(x), is a mathematical function that gives the logarithm of a number x with respect to the base e, where e is the mathematical constant approximately equal to 2.71828.

We can start by setting up the equation p = 250, where p represents the population in thousands. Then, we can solve for t, the number of years since 2000:

[tex]250 = 90*(34)^t[/tex]

[tex](34)^t = 250/90[/tex]

[tex](34)^t = 2.777...[/tex]

Taking the natural logarithm of both sides, we get:

t ln(34) = ln(2.777...)

t = ln(2.777...)/ln(34)

t ≈ 4.4

So, the population was more than 250,000 in the year 2000 + 4.4 ≈ 2004.4, which we can round up to 2005.

Therefore, the last year when the population was more than 250,000 was 2005.
