Write a division expresion that has the same value as 51. 2 divided by 6. 4 but is easier to use to find the value. Then, find the value using long division

The number of students in class a is 15, the mean score of class c is 5.5, and the mean score of all three classes is 6.5.

In mathematics, the mean or average is a measure of central tendency that represents the typical value or a central value of a set of numbers. It is calculated by adding up all the values in the set and then dividing by the number of values in the set. The mean is commonly used in statistics to summarize a large amount of data into a single value that is more easily understood. It is often used to represent the "average" or "typical" value of a set of data. For example, the mean score of a class on a test can give an idea of how well the class performed overall.

We can use the formula for the mean to set up two equations, one for the mean score of class a and one for the mean score of all three classes:

For class a and b combined:

(6x + 25 × 8)/ (x + 25) = 7.25

Simplifying this equation gives us:

6x + 200 = 7.25(x + 25)

Expanding the brackets and simplifying further gives:

6x + 200 = 7.25x + 181.25

Subtracting 6x and 181.25 from both sides gives:

18.75 = 1.25x

Therefore, x = 15

For all three classes:

(6x + 25 × 8 + 20y) / (x + 25 + 20) = 6.5

Substituting x = 15 into this equation gives:

(6 ×15 + 25 × 8 + 20y) / (15 + 25 + 20) = 6.5

Simplifying and solving for y gives:

(90 + 200 + 20y) / 60 = 6.5

Simplifying further gives:

y = 5.5

Therefore, the number of students in class a is 15, the mean score of class c is 5.5, and the mean score of all three classes is 6.5.

The axis of symmetry is located at a distance of 6.67 feet from one side of the smile and the height of the smile at the axis of symmetry is 0.891 feet.

The equation of the Amazon Smile logo is given by:

h(x) = -0.03x² + 0.4x

To find the axis of symmetry, we need to use the formula:

x = -b / 2a

where a and b are the coefficients of the quadratic equation ax²  + bx + c = 0.

a = -0.03 and b = 0.4.

x = -0.4 / 2(-0.03) = 6.67 feet

Therefore, the axis of symmetry is located at a distance of 6.67 feet from one side of the smile.

To find the height of the smile at the axis of symmetry, we need to substitute x = 6.67 into the given equation:

h(6.67) = -0.03(6.67)² + 0.4(6.67) = 0.891 feet

Therefore, the axis of symmetry is located at a distance of 6.67 feet from one side of the smile and the height of the smile at the axis of symmetry is 0.891 feet.

Answer:

Step-by-step explanation:

You want to compare the average rates of change on the interval [-6, -3] of the functions f(x) = 4x² and g(x) = 8x².

The average rate of change of p(x) on the interval [a, b] is given by ...

  ARC = (p(b) -p(a))/(b -a)

The average rate of change is ...

  ARC = (f(-3) -f(-6))/(-3 -(-6))

  ARC = (36 -144)/3 = -108/3 = -36

The average rate of change of f(x) on [-6, -3] is -36.

The average rate of change is ...

  ARC = (72 -288)/3 = -216/3 = -72

The average rate of change of g(x) on [-6, -3] is -72.

The ratio of the rates of change is ...

  ARC(g(x))/ARC(f(x)) = -72/-36 = 2

The average rate of change of g(x) is 2 times that of f(x).

We hope you noticed that g(x) is f(x) scaled vertically by a factor of 2. That scale factor is the ratio of the rates of change of the two functions.

Among the given options, the number of trials that comes closest to a large number is 200 trials (option D). Therefore, we would expect the experimental probability to be closest to 1/8 after 200 trials.

What is probability?

The probability of randomly choosing the number 5 from the bag of 8 cards is:

P(choosing 5) = number of 5 cards / total number of cards

Since there is only one card numbered 5 in the bag, the probability of choosing the number 5 is 1/8.

The experimental probability of choosing the number 5 after "n" trials can be calculated by counting the number of times the number 5 is chosen in "n" trials and dividing by "n".

For example, after 50 trials, we expect to choose the number 5 approximately:

P(choosing 5 after 50 trials) = number of times 5 is chosen in 50 trials / 50

We can simplify this expression as:

P(choosing 5 after 50 trials) = (1/8) x number of times 5 is chosen in 50 trials

Similarly, we can calculate the experimental probability for 100, 150, and 200 trials:

P(choosing 5 after 100 trials) = (1/8) x number of times 5 is chosen in 100 trials

P(choosing 5 after 150 trials) = (1/8) x number of times 5 is chosen in 150 trials

P(choosing 5 after 200 trials) = (1/8) x number of times 5 is chosen in 200 trials

To determine which number of trials would give us the experimental probability closest to 1/8, we need to consider the law of large numbers, which states that as the number of trials increases, the experimental probability approaches the theoretical probability.

Therefore, we would expect the experimental probability to be closest to 1/8 after a large number of trials. Among the given options, the number of trials that comes closest to a large number is 200 trials (option D). Therefore, we would expect the experimental probability to be closest to 1/8 after 200 trials.

Problem 1: The best approximation for finding the price of an individual product is (b) Marginal Cost. This is because marginal cost represents the cost of producing one additional unit of the product. Problem 2: You get profit when (c) Revenue is more than cost. When the revenue generated from selling products is greater than the cost of producing those products, you will have a positive profit.

For problem 1, the best approximation for finding the price of an individual product would be the Marginal Cost. This is because it takes into account the additional cost of producing one more unit of the product, which directly affects the price.

For problem 2, the correct answer would be c) When Revenue is more than cost. This is because profit is calculated by subtracting the cost of producing the product from the revenue earned from selling it. If the revenue is higher than the cost, then there is profit. If the cost is higher than the revenue, then there is a loss. When the cost is equal to the revenue, there is no profit or loss, just a break-even point.

Area of a parallelogram = base area × height

78 = 13 × height

Height = 78/13 = 6 mm.

Total area of wall space = 2 × [8(10) + 9(15)]

Total area of wall space = 2 × [80 + 135]

Total area of wall space = 2(215) = 430 ft².

(a) To find the perimeter of the trapezoidal prism, we need to find the lengths of all four sides. Let's call the shorter base of the trapezoid "b1", the longer base "b2", and the height "h". Then we have:

b1 = [tex]\sqrt{4ft^{2} }[/tex] = 2t[tex]\sqrt{f}[/tex]

b2 = b1 + 2h = 2t[tex]\sqrt{f}[/tex]  + 2(3.2) = 2t[tex]\sqrt{f}[/tex]  + 6.4

h = 3.2

The perimeter is then:

P = b1 + b2 + 2h = 2t[tex]\sqrt{f}[/tex]  + 6.4 + 2(3.2) = 2t[tex]\sqrt{f}[/tex]  + 12.8

So Elroy needs to purchase 5P feet of roping:

5P = 5(2t[tex]\sqrt{f}[/tex]  + 12.8) = 10t[tex]\sqrt{f}[/tex] ) + 64

(b) The total surface area of the trapezoidal prism is:

A = 2(b1+b2)h + 2b1t = 2(2t[tex]\sqrt{f}[/tex]  + 2t[tex]\sqrt{f}[/tex]  + 6.4)(3.2) + 2(2t[tex]\sqrt{f}[/tex] )(t) = 12.8t[tex]\sqrt{f}[/tex] + 25.6f[tex]t^{2}[/tex]

The area that will have gold leaf is the lateral surface area, which is:

[tex]A_{lateral}[/tex] = (b1 + b2)h = (2t[tex]\sqrt{f}[/tex]  + 2t[tex]\sqrt{f}[/tex]  + 6.4)(3.2) = 20.48t[tex]\sqrt{f}[/tex]

So the percentage of the area that will have gold leaf is:

([tex]A_{lateral}[/tex]  / A) x 100% = (20.48t[tex]\sqrt{f}[/tex]  / (12.8t[tex]\sqrt{f}[/tex]  + 25.6f[tex]t^{2}[/tex])) x 100%

Simplifying:

([tex]A_{lateral}[/tex]  / A) x 100% = (20.48 / (12.8 + 25.6/[tex]t^{2}[/tex])) x 100%

Using the given values of f = 1/2 and t = 2, we get:

([tex]A_{lateral}[/tex]  / A) x 100% = (20.48 / (12.8 + 25.6/4)) x 100% ≈ 48%

Answer:

To find the hypotenuse (c) of a right triangle with a height of 4 units and a base of 12 units, we can use the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The Pythagorean Theorem can be expressed as:

c^2 = a^2 + b^2

where c is the hypotenuse, and a and b are the lengths of the other two sides.

In this case, the height (a) is 4 units and the base (b) is 12 units.

Plugging these values into the Pythagorean Theorem equation, we get:

c^2 = 4^2 + 12^2

c^2 = 16 + 144

c^2 = 160

Taking the square root of both sides to solve for c, we get:

√(c^2) = √160

c = √160

So, the hypotenuse (c) of the triangle is √160

                | l

                |

                A

Let us first find the coordinates of the centers C1, C3, C5, and C7. Since all the circles are tangent to line l at point A, the centers must lie on the perpendicular bisector of the line segment joining A to the centers. Let us denote the distance from A to the center Cn by dn. Then, the coordinates of Cn are given by (an, dn), where an is the x-coordinate of point A.

Using the Pythagorean theorem, we can write the following equations relating the distances dn:

d1 = sqrt((d3 - 2)^2 - 1)

d3 = sqrt((d5 - 4)^2 - 9)

d5 = sqrt((d7 - 6)^2 - 25)

We can solve these equations to obtain:

d1 = sqrt(16 - (d7 - 6)^2)

d3 = sqrt(4 - (d7 - 6)^2)

d5 = sqrt(1 - (d7 - 6)^2)

Now, let us consider the region S that lies inside exactly one of the four circles. This region is bounded by the circle of radius 1 centered at C1, the circle of radius 3 centered at C3, the circle of radius 5 centered at C5, and the circle of radius 7 centered at C7. Since the circles are all tangent to line l at point A, the boundary of region S must pass through point A.

The maximum possible area of region S occurs when the boundary passes through the centers of the two largest circles, C5 and C7. To see why, imagine sliding the circle of radius 1 along line l until it is tangent to the circle of radius 3 at point B. This increases the area of region S, since it adds more points to the interior of the circle of radius 1 without removing any points from the interior of the other circles. Similarly, sliding the circle of radius 5 along line l until it is tangent to the circle of radius 7 at point C also increases the area of region S. Therefore, the boundary of region S must pass through points B and C.

Using the coordinates we obtained earlier, we can find the x-coordinates of points B and C as follows:

x_B = a - 2 - sqrt(9 - (d7 - 6)^2)

x_C = a + 6 + sqrt(9 - (d7 - 6)^2)

To maximize the area of region S, we want to maximize the distance BC. Using the distance formula, we have:

BC^2 = (x_C - x_B)^2 + (d5 - d3)^2

Substituting the expressions we derived earlier for d3 and d5, we get:

BC^2 = 32 - 2(d7 - 6)sqrt(9 - (d7 - 6)^2)

To maximize BC^2, we need to maximize the expression inside the square root. Let y = d7 - 6. Then, we want to maximize:

f(y) = 9y^2 - y^4

Taking the derivative of f(y) with respect to y and setting it equal to zero, we get:

f'(y) = 18y - 4y^3 = 0

This equation has three solutions: y = 0, y = sqrt(6)/2, and y = -sqrt(6)/2. The only solution that gives a maximum value of BC^2 is y = sqrt(6)/2, which corresponds to d7 = 6 + sqrt(6)/2.

Substituting this value of d7 into our expressions for d1, d3, and d5, we obtain:

d1 = sqrt(16 - (sqrt(6)/2)^2) = sqrt(55/2)

d3 = sqrt(4 - (sqrt(6)/2)^2) = sqrt(19/2)

d5 = sqrt(1 - (sqrt(6)/2)^2) = sqrt(5/2)

Using these values, we can compute the coordinates of points B and C as follows:

x_B = a - 2 - sqrt(9 - (sqrt(6)/2)^2) = a - 2 - sqrt(55)/2

x_C = a + 6 + sqrt(9 - (sqrt(6)/2)^2) = a + 6 + sqrt(55)/2

The distance between points B and C is then:

BC = |x_C - x_B| = 8 + sqrt(55)

Finally, the area of region S is given by:

Area(S) = Area(circle of radius 5 centered at C5) - Area(circle of radius 7 centered at C7)

= pi(5^2) - pi(7^2)

= 25pi - 49pi

= -24pi

Since the area of region S cannot be negative, the maximum possible area is zero. This means that there is no point that lies inside exactly one of the four circles. In other words, any point that lies inside one of the circles must also lie inside at least one of the other circles.

What is fraction?

A fraction represents a part of a whole, and it is written in the form of one integer written above another, separated by a horizontal line. The integer on top is called the numerator, and the integer on the bottom is called the denominator.

The numerator represents the number of parts being considered, while the denominator represents the total number of equal parts that make up the whole. For example, the fraction 3/4 represents three parts out of a total of four equal parts.

Fractions can be used to represent values that are not whole numbers, such as halves, thirds, quarters, etc. They are commonly used in everyday life, such as when measuring ingredients in cooking, dividing up a pizza or a cake, or expressing a probability.

To find the amount of granola in the bowl, we need to subtract the total amount of yogurt and blueberries from the total volume of the bowl.

First, let's add up the yogurt and blueberries:

7/8 cup Greek yogurt + 1 1/4 cup blueberries

= 7/8 + 5/4 (we need to find a common denominator)

= 14/16 + 20/16

= 34/16

Next, let's convert the total volume of the bowl to a fraction with a common denominator of 16:

3 1/2 = 7/2 = 56/16

Now we can find the amount of granola:

Amount of granola = Total volume of bowl - Amount of yogurt - Amount of blueberries

= 56/16 - 34/16

= 22/16

Simplifying the fraction, we get:

Amount of granola = 11/8

Therefore, 11/8 cup of the bowl is made up of granola.

The relative frequency of students that are of the 1 to 5 class and are left-handed is 40%.

Relative frequency is the ratio of the number of times an event occurs to the number of trials. This can be expressed as a fraction, a percentage, or a proportion.

This can be calculated using the following equation:

Relative Frequency = (Number of Left-Handed Students in 1 to 5 Class / Total Number of Students in 1 to 5 Class) x 100

Relative Frequency = (17 / (17 + 25)) x 100

Relative Frequency = 40%

This calculation shows that 40% of students in the 1 to 5 class are left-handed. This percentage can be rounded to the nearest whole percentage, giving the answer of 40%.

By comparing the relative frequency of left-handed students in the 1 to 5 class to the relative frequency in the other classes, it can be seen that the 1 to 5 class has the highest relative frequency of left-handed students.

This could be due to the developmental stage of students in this age group, as studies have shown that being left-handed is more common in children aged 5 to 10 than in adults.

Alternatively, it could be due to cultural factors, such as left-handed students feeling more comfortable in the 1 to 5 class due to the younger age group.
