Answer:

\(P = 48 in\),\(A= 120in^2\)

Step-by-step explanation:

Again we can use Pythagorean theorem to find the missing side

x^2 + 15^2 = 17^2

x^2 + 225 = 289

Subtract 225 from both sides

x^2 = 64

Find the square root of both sides

√x^2 = √64

x = 8

So

l = 15in, w = 8in

P=2(15) + 2(8)

P = 30 + 18

P = 48 in

A= 15(8)

A= 120in^2

Answer:

a. 0.0209 = 2.09% probability that among the 879 challenges, the number of overturned calls is exactly 231.

b. 231 is less than 2.5 standard deviations above the mean, which means that 231 overturned calls among 879 challenges is not a significantly high result.

Step-by-step explanation:

For each challenge, there are only two possible outcomes. Either it was overturned, or it was not. The probability of a challenge being overturned is independent of any other challenge. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

Significantly high:

The expected value of the binomial distribution is:

\(E(X) = np\)

The standard deviation of the binomial distribution is:

\(\sqrt{V(X)} = \sqrt{np(1-p)}\)

If a value is more than 2.5 standard deviations above the mean, this value is considered significantly high.

25% of the challenges are successfully upheld with the call overturned.

This means that \(p = 0.25\)

879 challenges

This meas that \(n = 879\)

a. If the 25% rate is correct, find the probability that among the 879 challenges, the number of overturned calls is exactly 231.

This is P(X = 231). So

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 231) = C_{879,231}.(0.25)^{231}.(0.75)^{648} = 0.0209\)

0.0209 = 2.09% probability that among the 879 challenges, the number of overturned calls is exactly 231.

b. If the 25% rate is correct, find the probability that among the 879 challenges, the number of overturned calls is 231 or more. If the 25% rate is correct, is 231 overturned calls among 879 challenges a result that is significantly high

The mean is:

\(E(X) = np = 879*0.25 = 219.75\)

The standard deviation is:

\(\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{879*0.25*0.75} = 12.84\)

\(219.75 + 2.5*12.84 = 251.85 > 231\)

231 is less than 2.5 standard deviations above the mean, which means that 231 overturned calls among 879 challenges is not a significantly high result.

Answer:

Step-by-step explanation:

Tungsten is a very hard and strong metal that is commonly used in the production of various types of high-strength materials, such as steel alloys, filaments for incandescent light bulbs, and electrical contacts. Tungsten has the highest tensile strength of any metal, which means it can withstand the highest amount of stress without breaking or deforming. However, tungsten is not very resistant to corrosion, especially in the presence of oxygen. At high temperatures, tungsten can react with oxygen to form tungsten oxide, which can cause corrosion of the metal.

Tantalum, on the other hand, is a highly corrosion-resistant metal that is often used in applications where exposure to oxygen and other corrosive materials is a concern. Tantalum has a natural oxide layer on its surface that helps protect the metal from corrosion. This oxide layer is very stable and adheres strongly to the underlying metal, providing an effective barrier against oxygen and other corrosive substances. Tantalum also has a relatively high tensile strength, making it a good choice for applications where both strength and corrosion resistance are important considerations.

In summary, while tungsten has the highest tensile strength of any metal, it is not as resistant to corrosion as some other metals, such as tantalum. Tantalum is highly resistant to corrosion by oxygen and other corrosive substances, making it a good choice for applications where exposure to these materials is a concern. Tantalum also has a relatively high tensile strength, making it a good choice for applications where strength is important.

Answer:

  13.3 m

Step-by-step explanation:

Let d represent the length of the diagonal. Then the length of the rectangle is (d-2) and the width is (d-6). The area is the product of length and width, so is ...

  A = LW

  83 = (d -2)(d -6) = d² -8d +12

  71 = d² -8d . . . . . . . . subtract 12 to get the constant out of the way

  d² -8d +16 = 87 . . . . add (-8/2)² = 16 to both sides to complete the square

  (d -4)² = 87 . . . . . . . write as a square

  d -4 = √87 . . . . . . . positive square root

  d = 4 +√87 ≈ 13.3 . . . . add 4

The diagonal is about 13.3 meters long.

Additional comment

If you check to see if the side lengths actually correspond to those of a rectangle, you find that they do not. The geometry described here is impossible. The rectangle with the proposed relations between sides and diagonal would have a diagonal of about 12.899 m and an area of about 75.19 m².

Answer:

m = 5

Step-by-step explanation:

A quadratic function is in the form \(ax^{2} +bx+c\).

To factor an equation, you are looking for two numbers that multiply to c (are factors of c), and add to b. In this case, c = -15, and b = 2.

The factors of -15 include 1, 3, 5, 15, -1, -3, -5, and -15.

After looking through the possible combinations, we can come to the conclusion that the only factors that multiply to -15 and add to 2 are 5 and -3, as 5 x -3 = -15, and 5 + -3 = 2.

You can now plug these numbers into the factored form (x + factor1)(x + factor2).

This then becomes (x + -3)(x + 5) or (x - 3)(x + 5).

Therefore, m = 5.

The parameters that are needed to calculate a probability are listed as follows:

Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes, hence it is the same as a relative frequency.

The total number of periods is given as follows:

5 + 6 + 4 = 15.

The frequency of each class is given as follows:

Answer:

19 and 29/32 or 19.90625

Step-by-step explanation:

So the 1st Way: We could simplify it and make them into improper fraction in a way like this:

13/4 * 49/8

We can then just multiply the top row and the bottom row:

13 * 49 = 637

4 * 8 = 32

637/32 = 19 and 29/32

The 2nd Way: We could literally add 6 and 1/8, 3.25 times

(I'm so sorry this is a way lol but I couldn't think of another)

6.125 + 6.125 + 6.125 + 6.125(0.25) = 18.375 + 1.53125 = 19.90625 :P

Answer:

B) x = -5

Step-by-step explanation:

The zero of a graph is the inputted value in which the output is 0. Therefore, we must find the x-value that makes the y-value be 0. In the graph, we see that y = 0 at (-5, 0). The x-value of the coordinate (-5, 0) is -5. Therefore, the zero of the function in the graph is x = -5.

The probability of rolling a die and getting a 2, then a 5, is 1/36.

To determine the probability of rolling a die and getting a 2, then a 5, we need to multiply the probabilities of each event happening.

First, let's consider the probability of rolling a die and getting a 2. Since there are six equally likely outcomes when rolling a fair six-sided die (numbers 1 to 6), the probability of rolling a 2 is 1/6.

Now, let's consider the probability of rolling a die and getting a 5. Again, there are six equally likely outcomes, so the probability of rolling a 5 is also 1/6.

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

Probability of rolling a 2 and then a 5 = (1/6) * (1/6) = 1/36.

Therefore, the probability of rolling a die and getting a 2, then a 5, is 1/36.

It's important to note that each roll of the die is an independent event, meaning that the outcome of one roll does not affect the outcome of the next roll. Therefore, the probability of rolling a 2 and then a 5 remains constant at 1/36 regardless of previous rolls or the order in which they occur.
