Using the proportion of students who enjoy watching Dancing with the Stars from Grace's survey, we can estimate that approximately 133 students at her school are expected to enjoy the show.

Grace surveyed 60 random students at her school and found that 14 enjoy watching Dancing with the Stars. With a total of 570 students in the school, we can establish a proportion to estimate how many students school-wide might enjoy the show. We do this by setting up a ratio of students who enjoy the show to the total number of students surveyed and then use that ratio to estimate the number for the entire school population.

To calculate, we take the ratio from the survey (14/60) and apply it to the total student body (570) like so:

Therefore, approximately 133 students in Grace's school are expected to enjoy watching Dancing with the Stars.

The problem 1.44 ÷ 0.3 equals to 4.8 when you using standard procedure for division, first moving the decimal point one position to the right for both numbers to get 14.4 ÷ 3.0, and then performing the division.

To find the result of 1.44 ÷ 0.3, you can use the standard procedure for division. One way to make this easier is to modify the divisor to be a whole number. To do this, we can move the decimal point one position to the right. But we have to do the same thing with the dividend too. Therefore, the problem becomes 14.4 ÷ 3.0. And when you perform this division, the answer is 4.8. So, 1.44 divided by 0.3 is equal to 4.8.

To find the area of the plate, we first calculate the radius using the given circumference and then plug this into our formula to find the area. The calculated area of the plate is approximately 94.52 square inches.

The student is asking for the area of a circular plate with a given circumference, using 3.14 for pi. The formula to calculate the area of a circle is A = πr². However, we only have the circumference, which allows us to find the radius using the formula C = 2πr, or rearranged to solve for r, r = C / (2π). Plugging in the given circumference of 34.5 inches, we find the radius to be 34.5 / (2 * 3.14) = 5.49 inches. Now, we can find the area by substitifying this value back into our area formula, A = πr², yielding A = (3.14) * (5.49²) ≈ 94.52 square inches.

To find the area of the circular plate having its circumference as 34.5 inches, we firstly calculate its radius using the formula r = Circumference/(2π) which gives approximately 5.49 inches. We then substitute the radius value in the formula for area of a circle (Area = πr²), yielding an area of approximately 94.52 square inches.

In mathematics, the circumference of a circle is related to its radius through the formula: Circumference = 2πr.

Given that the circumference of the plate is 34.5 inches, and we use 3.14 for π, we first work out the radius by rearranging the formula like so: r = Circumference / (2π).

Substitute the given values: r = 34.5 inches / (2*3.14)

Do the calculation: r approximately equals 5.49 inches.

Next, use the formula for the area of the circle which is: Area = πr².

Substitute r: Area = 3.14 * (5.49 inches)²

Calculate: Area is approximately 94.52 square inches.

The rancher should build a square with dimensions of 80 feet by 80 feet to obtain an area of 6400 square feet with 400 feet of fencing.

In this Mathematics task, the rancher is looking to build a rectangular area with a fixed amount of fencing. The information provided is:

Let l represent the length and w represent the width of the rectangle. Now, we know that a rectangle's perimeter is given by the formula, 2(l + w), and its area by l*w. Given the Area = 6400 and Length of Fencing = 400, we can set up the following two equations:

Solving these two equations simultaneously, we get l = 80 feet and w = 80 feet. So, the rectangle is actually a square, with equal length and width of 80 feet.

The inverse of the relation y=6x-3 is y = (x + 3) / 6.

To find an equation for the inverse of the relation y=6x-3, we need to follow a series of steps which involves swapping the variables, and then solving for the new y.

Start with the initial equation: y = 6x - 3.

Swap the variables x and y: x = 6y - 3.

Solve for y to find the inverse relation: Add 3 to both sides to get x + 3 = 6y, then divide both sides by 6 to isolate y, resulting in y = (x + 3) / 6.

The coordinates of the vertices of the new figure A'B'C'D' are A'(-8, 5), B' (-8, 8), C' (-5, 7), and D' (5, -4.5).

The coordinates of the vertices of quadrilateral ABCD are A(-6, 2), B(-6, 5), C(-3, 4), and D(-2.5, 2).

To translate the quadrilateral 2 units left and 3 units up, we subtract 2 from the x-coordinates

and add 3 to the y-coordinates of each vertex.

Therefore, the coordinates of the vertices of quadrilateral A'B'C'D' are A'(-8, 5), B' (-8, 8), C' (-5, 7), and D' (5, -4.5).

The base number in the given situation is 1.74. This number is commonly referred to as the growth rate.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The given equation y = 18.36(1.74)ˣ represents the situation.

The base number in this equation is 1.74. In an exponential function, the base is a constant multiplied by itself a certain number of times.

In this case, the base is multiplied by itself x number of times.

For example, on day 1 (x=1), the number of hits is 18.36(1.74)¹ = 32.5 hits.

On day 2 (x=2), the number of hits is 18.36(1.74)² = 56.6 hits. The base number represents the rate at which the number of hits is increasing. If the base is greater than 1, the number of hits is increasing at an exponential rate.

If the base is less than 1, the number of hits is decreasing at an exponential rate. If the base is equal to 1, the number of hits is increasing at a constant rate.

There were total 2000 people in the survey.

We can multiply relative frequency of any particular category with the total number of people to find the answer for each part.

Part A: How many males surveyed preferred playing sports?

Total Relative frequencies of Males who preferred playing sports = 0.30  

Number of Males preferred playing sports = 0.30 x 2000 = 600.

Part B: How many people surveyed preferred to read a book?

Total Relative frequencies of people who preferred reading book = 0.10 + 0.15 = 0.25

Number of people preferred reading book = 0.25 x 2000 = 500.

Part C: How many females were surveyed?

Total Relative frequencies of Females = 0.15 + 0.05 + 0.15 = 0.35

Number of Females surveyed = 0.35 x 2000 = 700.

The correct option is (b) 5/6.

Given ,

                   [tex]\frac{4}{5} n = \frac{2}{3} \\[/tex]

now do simply cross multiplication both sides,

                  4n × 3 = 2 × 5

                    4n = 10/3
