Answer: The graph represents the solution to the following sentence is the option number 3:

-3 -2 -1 0 1 2 3 4 5

This is because the set notation {x|x>4} U {x|x<-2} represents the union of all values of x that are greater than 4 and all values of x that are less than -2. The graph shows all the values of x that are greater than 4 and all values of x that are less than -2. The graph also includes the values of x between -3 and 5, it encompasses all the values that are greater than 4 and all values that are less than -2.

The graph represents the solution to the following sentence is (C).

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

We have,

{x | x >4 } ∪ {x | x < -2}

Here the set notation {x|x>4} U {x|x<-2} represents the union of all values of x that are greater than 4 and all values of x that are less than -2.

The graph displays all instances of x larger than 4 and all instances of x less than -2.

The graph covers all x values higher than or equal to 4, as well as all x values less than or equal to -2.

It also includes x values between -3 and 5.

Thus, the number line is C.

In the circle the area of the shaded region and the length of arc ADB is 23/4 π and 23/6 π respectively.

What is length of arc?

The distance along the curved line that makes up the arc is measured using the arc length formula (a segment of a circle). The arc length is, to put it simply, the distance that passes through the curved line of the circle that forms the arc. It should be noted that the arc's length is greater than the separation of its ends along a straight line.

Given that the circle has a center O.

The radius of the circle is 3 yd.

The measure of ∠AOB is 130°.

First find the measure of ∠ADB -

∠ADB = 360° - ∠AOB

Substituting the values in the equation -

∠ADB = 360° - 130°

∠ADB = 230°

Now find the area of the shaded region.

The area of the shaded region can be determined using the formula -

A = (θ/360)πr²

Substituting the values in the equation -

A = (230/360) π(3)²

A = (230/360) π 9

A = 23/4 π or 5.75 π

Therefore, the area of the shaded region is 5.75 π yd².

Now, find the length of the arc ADB.

The length of arc ADB can be determined using the formula -

Arc Length = (θ/360)2πr

Arc Length = (230/360)2π3

Arc Length = 23/6 π or 3.83 π

Therefore, the length of arc is 3.83 π yd.

We have, a box open from top and constituted from rectugular pieces of dimensions 12 inches and 20 inches. As we know, The volume of a box is V

= width (w) × height(h) ×length (l).

Now, equal squares of side x are cut from each corner of box and folded. We draw our box it looks like as seen above figure. We will notice here that the height will be x and that the height and length depend on x. Length of box, l = 20 - 2x and

The volume, V, of a box is defined as V(x) = 4x3 - 64x2 + 240x.

We have a box that opens from the top and is made of rectangular components that are 12 inches and 20 inches in length. As is common knowledge, a box's volume is V.

V = height (h) + width (w) + length (l).

From each corner of the box, equal squares of side x are now cut and folded. We create a box that resembles the image above. Here, we'll see that the height is x and that the relationship between height and length is x-dependent.

Box length, l = 20 - 2x, and

Box width, w = 12 - 2x

Thus, V is the volume (x) = W * H * I

V(x) = (12 - 2x) (x) (20 - 2x)

V(x) = ( 12 - 2x ) ( 20x - 2x²)

V(x) = 240x - 24x² - 40x² -4x³

V(x) = 4x³ - 64x² + 240x

Since the total of the inner angles of the rhombus is 360 degrees, the angle mV has a value of 90.

In Euclidean geometry, an angle is a shape made up of two rays, referred to as the angle's sides, that come together at a point in the middle known as the angle's vertex. An angle that is in the plane where the rays are placed can be created by two rays. An angle is also produced when two planes collide. They are known as dihedral angles. In planar geometry, an angle is the form produced by two rays or lines that share a termination. The English word "angle" comes from the Latin word "angulus," which means "horn." The vertex, also known as the sides of the angle, is where the two rays' common terminals meet.

given

m∠V + m∠W + m∠X + m∠Y = 360

Variance and standard deviation are two common measures of spread in statistics. The standard deviation is √30.25 = 5.5.

OB. s² = The sample variance is a measure of the spread of a set of data. To calculate the sample variance, the sum of the squares of the differences between each data point and the mean is divided by the number of data points minus one. In this case, the mean of the data set is (22+15+4+7+9)/5 = 11.

The differences between each data point and the mean are 11-22=-11, 11-15=-4, 11-4=7, 11-7=4, and 11-9=2. The sum of the squares of these differences is (-11)² + (-4)² + 7² + 4² + 2² = 121.

Dividing this by the number of data points minus one, which is 5-1=4, gives us a sample variance of 121/4 = 30.25.

The standard deviation is the square root of the sample variance, so in this case, the standard deviation is √30.25 = 5.5.

Answer:

We can start solving this problem by using a system of linear equations. Let x be the number of gallons of the 20% pure slime mixture and y be the number of gallons of the 80% pure slime mixture. We know the following:

The total amount of slime mixture is 1000 gallons. This means that x + y = 1000.

The final mixture is 65% pure slime, which means that 0.65 = (0.20)x + (0.80)y. This is because we are mixing 20% pure slime and 80% pure slime to get the final mixture.

We can use these two equations to solve for x, which is the number of gallons of the 20% pure slime mixture needed.

First, we'll use the first equation to solve for y in terms of x:

y = 1000 - x

Then we'll substitute this expression into the second equation:

0.65 = (0.20)x + (0.80)(1000 - x)

Simplifying we get:

0.65 = 0.20x + 800 - 0.80x

0.45x = 200

x = 200/0.45

x = 444.44 gallons

So, you would need 444.44 gallons of the 20% pure slime mixture to make 1000 gallons of a 65% pure slime mixture.
