The probability of selecting a pen from the first box is 1/8 (since there is only 1 pen out of 8 items in the box). The probability of selecting a crayon from the second box is 3/6 (since there are 3 crayons out of 6 items in the box).

To find the probability of both events happening together, we multiply the probabilities:

P(pen and crayon) = P(pen) x P(crayon)

P(pen and crayon) = (1/8) x (3/6)

Simplifying the fraction 3/6 to 1/2:

P(pen and crayon) = (1/8) x (1/2)

Multiplying the numerators and denominators:

P(pen and crayon) = 1/16

Therefore, the probability of selecting a pen from the first box and a crayon from the second box is 1/16.

Step-by-step explanation:

Formula: 2(aXb + bXc + cXa)

let, a = 7 m

     b = 7 m

     c = 5 m

then,

Answer: To check if the rates form a proportion, we need to calculate the rate (sit-ups per minute) for both Eric and John.

Eric's rate: 70 sit-ups / 2 minutes = 35 sit-ups per minute

John's rate: 108 sit-ups / 3 minutes = 36 sit-ups per minute

Now we can set up the proportion:

35/1 = 36/1

The rates do not form a proportion since they are not equal.

Step-by-step explanation:

To solve the inequality -6x < 36, we need to isolate x on one side of the inequality sign. We can do this by dividing both sides of the inequality by -6, remembering to reverse the inequality sign because we are dividing by a negative number:

-6x < 36

x > -6

Therefore, the solution set for the inequality is {x | x > -6}.

We want a circle that has center (-1,4) and just skims y=2. We can find the equation of the circle knowing its center and its radius. Knowing that it skims y=2 the radius=4-2=2 (Do you know why? Think visually). Then, the standard form of a circle is given by (x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius. So the equation is (x+1)^2+(y-4)^2=4

Therefore, the length of LM is 85.5.

Length is a measure of the size or extent of an object or a distance between two points. It refers to the longest dimension of an object or the distance between two points in space, typically measured in units such as inches, centimeters, meters, or miles. In mathematics, length is also used to describe the size of a line segment or a curve, which can be measured using various techniques such as Euclidean distance, arc length, or fractal dimension. Length is an important concept in many fields, including physics, engineering, geometry, and statistics.

Since LM is the midsegment of ABCD, it is parallel to both AB and DC, and its length is equal to the average of the lengths of AB and DC.

The length of LM can be found using the formula:

[tex]LM = (AB + DC) / 2[/tex]

Substituting the given values, we get:

[tex]LM = (46 + 125) / 2[/tex]

[tex]LM = 171 / 2[/tex]

[tex]LM = 85.5[/tex]

Therefore, the length of LM is 85.5.

The probability that a randomly selected student studies Hindi or Maths is 0.60 or 60%.

We can use the formula P(A or B) = P(A) + P(B) - P(A and B) to find the probability that a randomly selected student studies Hindi or Maths is calculated by adding the probabilities of studying Hindi and Maths and subtracting the probability of studying both Hindi and Maths.

P(Hindi or Maths) = P(Hindi) + P(Maths) - P(Hindi and Maths)

P(Hindi or Maths) = 0.30 + 0.45 - 0.15

P(Hindi or Maths) = 0.60

Answer:

x = -10

Step-by-step explanation:

To solve the equation:

x - 4 = 16 + 3x

Collect like terms:

x - 3x = 16 + 4

Then solve:

-2x = 20

x = -10

Answer: x is -10

Step-by-step explanation:

x - 4 = 16+3x

Transposing the x, and arranging in one side of equation

x - 3x = 16 + 4

now we changed the positions of x and we can simplify it.

so,

x - 3x = -2x -----------------(1)

16 + 4 = 20 ----------------(2)

Therefore the x - 3x = 16 + 4 will change into -2x = 20

Then x = 20 ÷ -2 = -10

x = -10

Answer: The variables h and k in the general formula for a cube root function affect the graph by causing a horizontal and vertical shift, respectively. The value of h determines the horizontal position of the graph by shifting it to the right or left along the x-axis. If h is positive, the graph will shift to the right, and if h is negative, the graph will shift to the left. On the other hand, the value of k determines the vertical position of the graph by shifting it up or down along the y-axis. If k is positive, the graph will shift upward, and if k is negative, the graph will shift downward. It is important to note that these shifts do not affect the shape of the graph, only its position on the coordinate plane. Therefore, changing the values of h and k in the general formula for a cube root function will cause the graph to shift, but the overall shape of the graph will remain the same.

Step-by-step explanation:

Based on the data given, the probability of the next roll of the die being a 4 is 30%.

what is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

To find the probability of rolling a 4 on the next roll, we need to divide the number of times 4 was rolled by the total number of rolls. In this case, 4 was rolled 9 times out of a total of 30 rolls.

So the probability of rolling a 4 on the next roll is:

9/30 = 3/10 = 0.3 = 30%

Therefore, based on the data given, the probability of the next roll of the die being a 4 is 30%.

b) angle OBA = 2x

A circle is a shape consisting of all points in the plane that are at a specified distance from a specified point (center). Correspondingly, it is a curve drawn by points moving in the plane at a constant distance from a point. The distance from any point of the circle to the center is called the radius. Normally the radius should be a positive number.

Specifically, a circle is a simple closed curve that divides a plane into two regions inside and outside. In everyday use, the term "circle" can be used interchangeably to refer to the entire shape, including the boundary or interior of the shape. In strict technical usage the circle is just the boundary and the whole figure is called the disk.

In ΔOCA;

OC = OA  [Radius of circle]

So, m∠OCA = m∠OAC

y = m∠OCA

y = m∠OAC

The transformation of the function f(x) = log2(x) involves shifting 2 units up and vertically compressing by a factor of 0.4.

Which function represents the transformation g(x)?

The following equation can be used to represent the transformation:

g(x) = 0.4*log2(x) + 2

Therefore, the function that represents the transformation g(x) is:

g(x) = 0.4*log2(x) + 2

To understand the transformation of the function f(x) = log2(x) into g(x), we need to first understand the individual transformations involved.

Vertical compression: When a function is vertically compressed by a factor 'a', its output values get multiplied by 'a'. This means that the function's range gets compressed by a factor of 'a'. In this case, the function f(x) = log2(x) is vertically compressed by a factor of 0.4. So, the output values of f(x) get multiplied by 0.4, which compresses the range of the function by a factor of 0.4.

Vertical shift: When a function is shifted 'b' units up or down, its output values get increased or decreased by 'b'. This means that the function's range gets shifted up or down by 'b'. In this case, the function f(x) = log2(x) is shifted 2 units up. So, the output values of f(x) get increased by 2, which shifts the range of the function 2 units up.

Putting these two transformations together, we get the transformation of the function f(x) = log2(x) into g(x) as follows:

g(x) = 0.4*log2(x) + 2

This equation represents a vertical compression of the function f(x) by a factor of 0.4, followed by a vertical shift of 2 units up.

Answer:

The area of the rectangle is 24x^5 y^2.

Step-by-step explanation:

To find the area of a rectangle when the length is represented by 8x³y² and the width is represented by 3x²yº, you need to multiply the length by the width.

8x³y² represents the length and 3x²yº represents the width.

Therefore, the area (A) of the rectangle can be calculated as:

A = length x width

A = 8x³y² x 3x²yº

To simplify this expression, you can use the laws of exponents:

A = 8x³y² x 3x²y°

A = 8 x 3 x x³ x x² x y² x yº

A = 24x^(3+2) y^(2+0)

Simplifying further:

A = 24x^5 y^2

Therefore, the area of the rectangle is 24x^5 y^2.

A sentence to explain how I know this is not a perpendicular bisector is that line AB was not divided into two equal halves.

A possible mistake which Aaron made in his construction is: C. he did not use a pair of compasses to draw his arcs.

In Mathematics and Geometry, a perpendicular bisector can be defined as a type of line that bisects or divides a line segment exactly into two (2) equal halves and forms an angle that has a magnitude of 90 degrees at the point of intersection.

This ultimately implies that, the steps taken by Aaron for the construction of the perpendicular bisector for line AB is incorrect because it was not divided into two equal halves, even though it formed an angle that has a magnitude of 90 degrees at the point of intersection.

the rate of discount is double the rate of VAT. The selling price of the article without VAT is Rs. [tex]7,680.[/tex]

Let's assume that the original selling price of the article is Rs. [tex]8,000.[/tex]

Let the rate of discount be x and the rate of VAT be y.

We know that the selling price of the article with discount and VAT is Rs. [tex]6,689.60.[/tex]

So, we can write the following equation:

Selling price = (Original price - Discount) + VAT

[tex]Rs. 6,689.60 = (Rs. 8,000 - Rs. 8,000 x (x/100)) + (Rs. 8,000 - Rs. 8,000 x (x/100)) x (y/100)[/tex]

Simplifying the equation, we get:

[tex]Rs. 6,689.60 = Rs. 8,000 (1 - x/100 + y/100 - xy/10000)[/tex]

Now, we are given that the rate of discount is double the rate of VAT. So, we can write:

[tex]x = 2y[/tex]

Substituting this value in the equation above, we get:

[tex]Rs. 6,689.60 = Rs. 8,000 (1 - 3y/100 + 2y^2/10000)[/tex]

Simplifying this equation further, we get a quadratic equation in y:

[tex]2y^2 - 3y + 0.41505 = 0[/tex]

Solving this quadratic equation using the quadratic formula, we get:

[tex]y = 10.5 or y = 0.01988[/tex]

Since the rate of VAT cannot be 10.5%, we will take y = 0.01988 (approx. 2%).

Now, we can calculate the rate of discount using x = 2y:

x = 4%

So, the selling price of the article without VAT can be calculated as follows:

Selling price without VAT = Original price - Discount

[tex]= Rs. 8,000 - Rs. 8,000 x\times (4/100)[/tex]

[tex]= Rs. 7,680[/tex]

Therefore, the selling price of the article without VAT is Rs. [tex]7,680.[/tex]

S is not a basis for R3 because: c. S is linearly dependent and does not span R3.

A basis for a vector space is a set of vectors that are linearly independent and span the space.

Let's check if S = {(1, 1, 1), (0,1,1), (1,0,1), (0, 0, 0)} satisfies this definition of the basis or not.

Here, we have to find if the set is linearly dependent or not. If the set is linearly dependent, then it can't be a basis. To check the linearity of the set, we will set the equation for the linear combination of vectors of set S.

Then α1(1, 1, 1) + α2(0,1,1) + α3(1,0,1) + α4(0, 0, 0) = 0

For the above equation to hold true, α1 + α3 = 0α1 + α2 = 0α1 + α3 = 0

By solving the above equations, we get

α1 = -α3α2 = -α1α4 = 0

The above equation shows that α4 = 0 means there is always a trivial solution which makes it linearly dependent.

Therefore, it is not a basis.
