For the given triangle the value of x = 4.

In the given figure,

The triangles, ABC and DBE are similar

Since we know that,

Triangles that are similar to one another in shape but differ in size are known as similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

Therefore, we have the proportionality,

EC/BE = AD/DB

⇒ 2/3=x/10-x

After cross multiplying

⇒ 2(10-x)=3x

⇒ 20-2x=3x

⇒ 20=5x

Divide both sides by 5, and we get,

⇒  x = 4

Hence,

The value of x = 4.

Solving a system of equations we can see that the washer costs $750, and the dryer costs $250.

Let's define the variables:

x = cost of the washer.

y = cost of the dryer.

We know that the cost combined is $1000, then:

x  + y = 1000

And the washer cost 3 times the cost of the dryer, then we will get:

x = 3y

So we have a system of equations, we can replace the second equation into the first one, so we will get:

3y + y = 1000

4y = 1000

y = 1000/4

y = 250

The cost of the washer is:

x = 3*250 = 750

The standard deviation of the sample proportion is 0.0866.

Standard deviation is a measure of the amount of variation or dispersion of a set of data values from the mean or average value. It is used to describe the spread of a data set, and it provides a way to quantify the degree of variability or uncertainty in the data.

Standard deviation for a sample percentage is calculated as follows:

σp = √((p×(1-p))/n)

where p is the proportion of successes in the sample, n is the sample size.

In this case, p is given as 0.70 and n is given as 28. Plugging these values into the formula, we get:

σp = √((0.70×(1-0.70))/28)

σp = √((0.21)/28)

σp = √(0.0075)

σp ≈ 0.0866

Therefore, the standard deviation of the sample proportion is approximately 0.0866.

The answers are:

1. 2(x2 + 6x + 9) = 3 + 18

2. 2(x2 + 6x) = 3

Let's take a look at the first choice:

2(x² + 6x + 9) = 3 + 18

Now, we will multiply 2 with every member of the other multiplier on the left side:

2·x² + 2·6x + 2·9 = 3 + 18

2x² + 12x + 18 = 3 + 18

2x² + 12x - 3 = 18 - 18

2x² + 12x - 3 = 0

Let's take a look at the second choice:

2(x² + 6x) = 3

Now, we will multiply 2 with every member of the other multiplier on the left side:

2·x² + 2·6x = 3

2x² + 12x = 3

2x² + 12x - 3 = 0 Man that was so hard MARK ME Brainilest Thanks Peace

Step-by-step explanation:

The solution to the above algebra question is  (b) x-3, x+5.

To find the remaining factors of the polynomial x^3+4x^2-11x-30=0, we can use polynomial long division or synthetic division. However, since we are given that x+2 is a factor of the polynomial, we can use synthetic division to simplify the process.

We set up the synthetic division table as follows, using -2 as the divisor:

-2 | 1 4 -11 -30

|____-2__-4___30

| 1 2 -15 0

The bottom row of the table represents the coefficients of the quadratic polynomial obtained by dividing x^3+4x^2-11x-30 by x+2. The last term of the quadratic is 0, which indicates that x+2 is a factor of the polynomial. The remaining quadratic polynomial can be factored as:

x^2 + 2x - 15 = (x - 3)(x + 5)

Therefore, the remaining factors of the polynomial x^3+4x^2-11x-30=0 are x+2, x-3, and x+5.

The correct answer is (b) x-3, x+5.

Simple Interest (I)= P× T× R/ 100

= $530 × 1 year× 6%

= 530 × 1 × 6

= $3180

Therefore , The simple Interest is $3180.

Thank you ☺️☺️

The simple interest will be equal to $3180.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

Given that:-

principal (p) = $ 530

Interest Rate (R) = 6%

Time (T) = 1 year

Simple Interest (I) = ?

The formula to calculate the simple interest is given below:-

Simple Interest (I)= P× T× R/ 100

SI = $530 × 1 year× 6%

SI = 530 × 1 × 6

SI = $3180

Therefore, the simple interest will be equal to $3180.

v1 and v2 be two nonzero vectors perpendicular to 2 in R3.

We can calculate the dot product of each vector with 2 to determine if they are perpendicular.

v1•2 = (x1, y1, z1)•(2, 0, 0) = 2x1

v2•2 = (x2, y2, z2)•(2, 0, 0) = 2x2

If 2x1 = 0 and 2x2 = 0, then v1 and v2 are perpendicular to 2. To make sure they are not scalar multiples of each other, we can check that the coordinates of each vector are not all the same. Let's say v1 = (a, b, c) and v2 = (d, e, f). If a≠d, b≠e, and c≠f, then v1 and v2 are not scalar multiples of each other.

For example, let v1 = (1, 2, 3) and v2 = (4, 5, 6). Then v1•2 = 2 and v2•2 = 8, which both equal 0. Therefore, v1 and v2 are perpendicular to 2. Furthermore, since 1≠4, 2≠5, and 3≠6, v1 and v2 are not scalar multiples of each other.

Answer:

the probability that a randomly selected student received an A, B, or C is approximately 0.769, or about 76.9%.

Step-by-step explanation:

To find the probability that a randomly selected student received an A, B, or C, we need to add up the number of students who received each of these grades and divide by the total number of students in the class.

The total number of students in the class is:

total = A + B + C + D + E = 40 + 40 + 33 + 20 + 14 = 147

The number of students who received an A, B, or C is:

A + B + C = 40 + 40 + 33 = 113

Therefore, the probability that a randomly selected student received an A, B, or C is:

P(A or B or C) = (A + B + C) / total = 113 / 147 ≈ 0.769

So the probability that a randomly selected student received an A, B, or C is approximately 0.769, or about 76.9%.

Volume = (24x⁵ + 78x⁴ - 147x³ - 624x² - 360x)

Step-by-step explanation:

Container given in the picture is in the shape of a cuboid.

And volume of a cuboid is measured by the expression,

Volume of a cuboid = Length × width × height

Now substitute the measure of the container's dimensions given in the picture

Volume = (4x² + 3x)(x²- 8)(6x + 15)

             = [(4x² + 3x)(x²- 8)](6x + 15)

             = [4x²(x² - 8) + 3x(x² - 8)](6x + 15)

             = (4x⁴ - 32x² + 3x³ - 24x)(6x + 15)

             = (4x⁴ + 3x³ - 32x² - 24x)(6x + 15)

             = 6x(4x⁴ + 3x³ - 32x² - 24x) + 15(4x⁴ + 3x³ - 32x² - 24x)

             = 24x⁵+ 18x⁴ - 192x³ - 144x² + 60x⁴ + 45x³ - 480x² - 360x
