what is 55/63 in simplest form

Answer:62.5

Step-by-step explanation:

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.

The surface area of the rectangular prism is 35.5 square feet.

A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles.

The surface area of a rectangular prism is expressed as;

SA = 2lw + 2lh + 2wh

Where l, w, and h are the length, width, and height of the rectangular prism, and SA is the surface area.

Given that:

Length l = 2.5 ft

Width w = 1.5 ft

Height h = 3.5 ft

Substituting the given values, we get:

SA = 2lw + 2lh + 2wh

SA = 2(2.5 ft × 1.5 ft) + 2(2.5 ft × 3.5 ft) + 2(1.5 ft × 3.5 ft)

SA = 7.5 ft² + 17.5 ft² + 10.5 ft²

SA = 35.5 ft²

Given the integer data set containing 11, 13, 15, 17, x, and y, we know that the mode, median, and mean form an increasing arithmetic sequence.

Since the mode is the unique number that appears most frequently, either x or y must be equal to one of the existing numbers (11, 13, 15, or 17). Let's assume x is the mode. For the sequence to be increasing, the mode must be the smallest, so x = 11.

The median of the data set is the average of the two middle numbers when they are arranged in ascending order. With x = 11, the sorted sequence will be 11, 11, 13, 15, 17, and y. The median will be the average of 11 and 13, which is 12.

For the mean, we have (11+11+13+15+17+y)/6. We know the mean is greater than the median, which is 12. If we increase the mean to 13, we can solve for y:

(11+11+13+15+17+y)/6 = 13
67 + y = 78
y = 11

However, this would make the mode 11 as well, so it doesn't meet the unique requirement. Let's increase the mean to 14 and solve for y:

(11+11+13+15+17+y)/6 = 14
67 + y = 84
y = 17

Now, the mode, median, and mean are unique and form an increasing arithmetic sequence (11, 12, 14). Therefore, the greatest possible value of y is 17.

Approximately 30% of the sampled baseballs are too lively based on a cutoff coefficient of restitution of 0.630. The 95% lower confidence bound on this proportion is  0.154.

To find the proportion of the baseballs in the sampled population that are too lively, we need to count the number of baseballs in the sample that have a coefficient of restitution greater than 0.630 and divide by the total sample size

Number of baseballs with coefficient of restitution > 0.630 = 12

Total sample size = 40

Proportion of baseballs in the sample that are too lively = 12/40 = 0.3 = 30%

To find a 95% lower confidence bound on this proportion, we can use the formula

lower bound = p - zsqrt(p(1-p)/n)

where p is the sample proportion, z is the z-score associated with the desired confidence level (95% confidence level has a z-score of 1.96), and n is the sample size.

Substituting the values, we get:

lower bound = 0.3 - 1.96sqrt(0.3(1-0.3)/40) ≈ 0.154

a) Elroy needs to purchase 5 times the Perimeter feet of roping.

b) About 48% of the surface area of the platform will have gold leaf.

(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%

A rectangular playpen with length 12 feet and width 6 feet (since 2 x (12 + 6) = 36)

2) The fencing used for the given design is the sum of the lengths of all four sides. From the diagram, we can see that the two shorter sides have a length of 8 feet each, and the two longer sides have a length of 10 feet each. Therefore, the total fencing used is:

2(8 ft) + 2(10 ft) = 16 ft + 20 ft = 36 ft

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
