Answer:14.42

How to get it:Use Pythagorean Theorem to solve this problem. Since a squared plus b squared =c squared and we have an and c we can work backwards. Start by squaring 17 (17x17) which would be 289. Then do 9 squared (9x9) to get 81. Subtract 289-81 to get 208, square root this for your answer 14.4222 round to 14.42. You can check this by doing 14.4222 squared plus 9 squared then square root it and you should get approximately, but not exactly 17.

The solution to the inequality is m ≥ 2.

To solve the inequality 2 - m ≤ 6m - 12, we'll follow these steps:

1. Simplify both sides of the inequality:

  2 - m ≤ 6m - 12

  Rearranging the terms, we have:

  -m - 6m ≤ -12 - 2

  Combining like terms, we get:

  -7m ≤ -14

2. Divide both sides of the inequality by -7. Remember that when we divide by a negative number, the inequality sign must be reversed:

  (-7m) / -7 ≥ (-14) / -7

  Simplifying, we have:

  m ≥ 2

So, the solution to the inequality is m ≥ 2.

The probability of the student getting at least one question correct is approximately 0.893.

To solve this problem, we can use the binomial distribution formula:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where:

Using this formula, we can find the probability of getting different numbers of correct answers:

P(X = 0) = (10 choose 0) * (1/5)^0 * (4/5)^10 ≈ 0.107

P(X = 1) = (10 choose 1) * (1/5)^1 * (4/5)^9 ≈ 0.321

P(X = 2) = (10 choose 2) * (1/5)^2 * (4/5)^8 ≈ 0.302

P(X = 3) = (10 choose 3) * (1/5)^3 * (4/5)^7 ≈ 0.176

P(X = 4) = (10 choose 4) * (1/5)^4 * (4/5)^6 ≈ 0.059

P(X = 5) = (10 choose 5) * (1/5)^5 * (4/5)^5 ≈ 0.012

P(X = 6) = (10 choose 6) * (1/5)^6 * (4/5)^4 ≈ 0.002

P(X = 7) = (10 choose 7) * (1/5)^7 * (4/5)^3 ≈ 0.00026

P(X = 8) = (10 choose 8) * (1/5)^8 * (4/5)^2 ≈ 0.00002

P(X = 9) = (10 choose 9) * (1/5)^9 * (4/5)^1 ≈ 0.000001

P(X = 10) = (10 choose 10) * (1/5)^10 * (4/5)^0 ≈ 0.00000003

To find the probability of getting at least one correct answer, we can add up the probabilities of getting exactly one correct answer, exactly two correct answers, and so on:

P(at least one correct) = P(X >= 1) = P(X = 1) + P(X = 2) + ... + P(X = 10) ≈ 0.893

Therefore, the probability of the student getting at least one question correct is approximately 0.893.

Answer:

90 is the orrect answer because I said so

Step-by-step explanation:

Answer:

The answer is a = 99

Step-by-step explanation:

We can solve this using ratios

First we set up the equation:

\(\frac{a}{90}= \frac{110}{100}\)

Then cross-multiply:

\(100 * a = 90 * 110\)

Simplify:

\(100 * a = 9,900\)

Divide both sides by 100:

\(a = 99\)

Ta-Da! The answer is a = 99

Answer:

108, 108, 72

Step-by-step explanation:

Vertical angles are congruent and if the measure of 1 of the angles is 72 degrees and straight lines equal 180 degrees you have to subtract 72 from 180 which equals 108.

The area of the resulting surface of this infinite curve is π units.

In this question,

The infinite curve is y = e^−2x, x ≥ 0.

The curve is rotated about x-axis.

Since x ≥ 0, the limits will be 0 to ∞.

Then the area of the resulting surface is,

\(A= 2\pi \lim_{b\to \infty} (\int\limits^\infty_0{e^{-2x} } \, dx )\)

Now substitute,

u = -2x

⇒ du = -2dx

⇒ dx = \(-\frac{1}{2} du\)

Then,

\(\int\limits{-\frac{1}{2}e^{u} } \, du =-\frac{1}{2}\int\limits{e^{u} } \, du\)

Now substitute u and du, we get

⇒ \(-\frac{1}{2} \int\limits {e^{-2x} }(-2) \, dx\)

⇒ \(-\frac{-2}{2} \int\limits {e^{-2x} } \, dx\)

⇒ \((1) \int\limits {e^{-2x} } \, dx\)

⇒ \(\int\limits {e^{-2x} } \, dx\)

Thus the area of the resulting surface is

\(A= 2\pi \int\limits^\infty_0{e^{-2x} } \, dx\)

⇒ \(A= 2\pi [{e^{-2x}(\frac{1}{-2} ) } \,]\limits^\infty_0\)

⇒ \(A= \frac{2\pi}{-2} [{e^{-2(\infty)}-e^{-2(0)} } \,]\\\)

⇒ \(A= -\pi [0-1} \,]\\\)

⇒ \(A= \pi\)

Hence we can conclude that the area of the resulting surface is π units.

The corrected statement should look like this:
```java
int[] hours = {8, 12, 16};
```

It looks like you are trying to create an integer array in Java called "hours" and initialize it with the values 8, 12, and 16. The given statement has incorrect syntax.
Declare the integer array using "int[]" followed by the variable name "hours".

This tells the Java compiler that you want to create an array of integers called "hours".
Use the assignment operator "=" to assign values to the array.
Enclose the values you want to assign to the array within curly braces "{" and "}" and separate each value with a comma.
The corrected statement should look like this:
```java
int[] hours = {8, 12, 16};
```
Now, the "hours" integer array is initialized correctly with the given values.

The syntax for declaring and initializing an integer array in Java is:

```java
data Type[] array

Name = {value1, value2, value3, ...};
```
In this case, "data Type" is "int", "array

Name" is "hours", and the values are 8, 12, and 16.
Remember to keep your code clean and concise to avoid syntax errors and make it easier for others to understand.

Answer:

a= 4/3

Step-by-step explanation:

1.) Simplify both sides of the given equation:

1/4a + -5/6 = -1/2

2.) Add the 5/6 to both sides (cancels the -5/6)

1/4a + -5/6 (+5/6) = -1/2 (+5/6)

1/4a = 1/3

3.) Multiply both sides by 4 (the denominator)

4 * 1/4a = 1/3 * 4

a = 4/3

To check the solution, plug in 4/3 into a:

4/3/4 - 5/6 = -1/2

2.) Dividing fractions is also multiplication:

(4/3 * 1/4) - 5/6 = -1/2

3.) Get the difference of 1/3 and 5/6

1/3 - 5/6 = -1/2

4.) Simplify -3/6 (3 goes into 3 ONCE and into 6 TWO times)

-3/6 = -1/2

5.) Check to see if both sides match

-1/2 = -1/2

a. P(X = 6) = (7C6) * (0.40)^6 * (0.60)^1.  b. P(X = 7) = (7C7) * (0.40)^7 * (0.60)^0. c. P(X ≥ 6) = P(X = 6) + P(X = 7). d. the answer is A. No, because the probability that 6 or more of the selected adults believe in reincarnation is less than 0.05.

(a) To find the probability that exactly 6 of the selected adults believe in reincarnation, we can use the binomial probability formula. We need to calculate the probability of 6 successes (adults believing in reincarnation) out of 7 trials, with a success probability of 40%. This can be calculated as: P(X = 6) = (7C6) * (0.40)^6 * (0.60)^1.

(b) The probability that all of the selected adults believe in reincarnation can be calculated as the probability of 7 successes out of 7 trials, which is: P(X = 7) = (7C7) * (0.40)^7 * (0.60)^0.

(c) To find the probability that at least 6 of the selected adults believe in reincarnation, we can calculate the probability of 6 successes plus the probability of 7 successes: P(X ≥ 6) = P(X = 6) + P(X = 7).

(d) To determine if 6 is a significantly high number of adults who believe in reincarnation, we compare the calculated probability of 6 or more successes with a significance level, usually set at 0.05. If the calculated probability is less than 0.05, we can consider 6 as a significantly high number. Therefore, the answer is A. No, because the probability that 6 or more of the selected adults believe in reincarnation is less than 0.05.

Answer:

7/8 or 1/2

Step-by-step explanation:

Because if the siblings ate 1/8 and u simplify 1/8 and u will get 1/2

Let us suppose that the farmer buys x cows, y pigs and z sheep. The total cost of cows, pigs, and sheep bought by the farmer is

10x + 3y + 0.5z.

The total number of cows, pigs, and sheep bought by the farmer is

x + y + z.

Given that the farmer spent exactly 100 and bought exactly 100 animals, we can write two equations as follows.

:\($10x + $3y + $0.5z = $100 ---(1)x + y + z = 100 ---(2).\)

Multiplying equation (2) by 10 on both sides, we get

:10x + 10y + 10z = 1000

Subtracting this equation from equation (1), we get

:7y + 9.5z = 500

The LHS of the equation

7y + 9.5z = 500

is an odd number. This means that either y or z has to be odd and the other even. If y is even, then z has to be odd and vice versa. However, both

3y and 0.5z

are integers.

The solutions are:

x =

y = 8,

z = 40 ---(Option A)

or = 48,

y = 16,

z = 36

x = 44,

y = 24,

z = 32x

y = 32

z = 28

The farmer buys 52 cows, 8 pigs, and 40 sheep.

The probability that Marcus has to make the new dish exactly 15 times before it goes on the menu is approximately 0.053. The probability that the investor will double his investment is approximately 0.315.

To find the probability that Marcus has to make the new dish exactly 15 times before it goes on the menu, we need to calculate the probability of exactly 10 successes (perfect executions) out of the first 14 attempts and then the probability of a success on the 15th attempt. Each attempt has an 80% chance of success.

Using the binomial probability formula, the probability of exactly k successes in n attempts, with a success probability p, is given by:

\(P(X = k) = (n choose k) * (p^k) * ((1 - p)^(n - k))\)

In this case, we want to calculate\(P(X = 10) * P(X = 1) = (14 choose 10) * (0.8^10) * (0.2^4) * (0.8^1) = 0.0577 * 0.00016 ≈ 0.0092.\)

Therefore, the probability that Marcus has to make the new dish exactly 15 times before it goes on the menu is approximately 0.0092 or 0.92%.

To calculate the probability that the investor will double his investment, we need to consider the scenario where Marcus attempts the recipe once per day until the meeting. Since he has 6 days left and he has already executed the recipe 5 times successfully, he has 1 remaining attempt.

The probability of a success on the last attempt is 0.8, and the probability of failure is 0.2. Therefore, the probability that the investor will double his investment is P(X = 1) = 0.8.

Hence, the probability that the investor will double his investment is approximately 0.8 or 80%.

The binomial probability formula is used to calculate the probability of obtaining a certain number of successes in a fixed number of independent Bernoulli trials. In this case, Marcus's attempts to execute the recipe can be modeled as a binomial distribution since each attempt has a fixed probability of success (80%) and the attempts are independent. By applying the formula, we can determine the probabilities associated with the number of successes and make informed decisions based on those probabilities.

The required probability of drawing a red marble the 6th time is 1/2.

Given that,

A box contains 10 red marbles and 10 green marbles.

Sampling at random from this box five times without replacement, you have drawn a red marble all five times.

Without replacing any of the marbles.

We have to determine,

What is the probability of drawing a red marble the 6th time?

According to the question,

There are 10 red marbles and 10 green marbles,

The initial condition is to the same state at every step, so the probability to get a red marble is the same in each sampling  and is equal to the ratio of the number of red marbles to the total number of samples.

Therefore,

The probability of drawing a red marble the 6th time is,

\(P = \dfrac{10}{10+10}\\\\P = \dfrac{10}{20}\\\\P = \dfrac{1}{2}\)

Hence, The required probability of drawing a red marble the 6th time is 1/2.
