To determine the probability that a randomly selected guest is accepted by the host, we need more information about the scenario. For instance, we should know the total number of guests and the number of accepted guests. Let's say there are 'n' guests, and 'a' guests are accepted by the host.
Step 1: Identify the terms.
- n: Total number of guests
- a: Number of accepted guests
Step 2: Calculate the probability.
To find the probability, we'll divide the number of accepted guests (a) by the total number of guests (n). So, the probability is:
P(Accepted) = a / n
Step 3: Identify the type of probability.
In this case, the probability we've calculated is the "marginal probability," as it represents the likelihood of a single event occurring (a guest being accepted) without considering any other factors or events.

Answer:

In step-by-step explanation.

Step-by-step explanation:

Multiplying a fraction (like 1/2) is really just dividing by the denominator.

In this case, we can (mentally) divide 36 by 6.

36/6 = 6

So each 1/6 of 36 is 6.

Then we just add 1/6 of 36 five times to get 5/6

6+ 6+ 6+ 6+ 6 (or 6 x 5) and we get 30.

1. plug in the values

3(2) - (-1) = 7; true

2(2) + 3(-1) = 1

4 -3 = 1; true

yes, the point is true for the system. .

the solution is referring to where both the lines intercept on the graph.

3. replace 'y' in the first equation with the second equation

3x + 6x + 1 = 10

9x + 1 = 10

9x = 9

x = 1

plug x = 1

y = 6(1) + 1

y = 7

4. elimiate the common terms which is 'n' which gives;

5m = -5

m = -1

plug in to find 'y' AKA 'n'

3(-1) - n = 2

-3 - n = 2

Answer: V = 2527.2 in^3

Step-by-step explanation:

V = Bh

that is, Volume = base area x height

the base area is the hexagon, and the height is given as 12.

Think of dividing the hexagon into 6 equal triangles, with height 7.8

so the area of all 6 triangles, (effectively the area of the hexagon), will be:

6(0.5 x 9 x 7.8) = 210.6 in^2

multiply this by the height to get the volume:

210.6 x 12 = 2527.2 in^3

thats it!

V = 2527.2 in^3

Answer:

f(x) ≥ 0 over the interval [5, ∞).

( option A )

A valid prediction about the continuous function f(x) is the values of f(x) for x ≥ 5 are greater than or equal to zero. The correct answer is option A.

A function is continuous if its graph has no gaps or jumps. A function f(x) is said to be continuous at a point x=a if the limit of f(x) as x approaches a exists and equals f(a). A function on an interval is continuous if it is continuous at every point in that interval.

The table is given in the question as follows:

x: -5, -3, -1, 1, 3, 5, 7

f(x): 8, 4, 0, -2, -2, 0,4

Using the given values of x and f(x), we can make some observations about the behavior of the function f(x) over the given intervals:

Over the interval [5, ∞), f(x) is positive for all x, since all the values of f(x) for x ≥ 5 are greater than or equal to zero.

Therefore, option A is a valid prediction.

The missing table is attached below.

In the given equation x = 9 is the value that satisfies the equation.

The square root of a number is a value that, when multiplied by itself, equals the original number. For example, the square root of 9 is 3, because \(3*3 = 9\). The symbol for square root is "√" and it can also be represented as "sqrt".

In the given equation \(x = 9\) is the value that satisfies the equation.

To find the value of x in the equation \(3 \sqrt{x} = 9\), we first need to square both sides of the equation to eliminate the square root.

\(3 \sqrt{x} = 9\)

Squaring both sides:

\((3 \sqrt{x} )^2 = 9^2\)

\(x = 9^2 / 3^2 = 9^2 / 9 = 9\)

Therefore, x = 9 is the value that satisfies the equation.

J in 55min

J in 45min ( bigger hose)

Alternative method

The trick is to convert the numbers you are given to numbers that you can add together.

You have minutes per pool. You can’t work with that. But if you take the reciprocal of each you get pools per minute.

So if the first hose fills 1/55 = 0.01818 pools per minute and the second one fills 1/45 = 0.0222 pools per minute, then both of them will fill 0.1818 + 0.0222 = 0.04040 pools per minute. If we take the reciprocal of that we end up with 1/0.04040 = 24.75 minutes per pool.

y₁ =  [1  -4  0  1] and y₂ = [5  1  -6  -1] is the orthogonal basis for w using Gram-Schmidt process.

Given,

The set;

x₁ = [1  -4  0  1]

x₂ = [7  -7  -6  1]

We have to produce the orthogonal basis for w using the Gram-Schmidt process;

Here,

y₁ = x₁ =  [1  -4  0  1]

Now,

Solve for y₂

y₂ = x₂ - [x₂y₁ / y₁y₁] y₁

That is,

y₂ = [7  -7  -6  1] - ( [7  -7  -6  1] [1  -4  0  1] / [1  -4  0  1] [1  -4  0  1] ) × [1  -4  0  1]

y₂ =  [7  -7  -6  1] - (7 + 28 - 0 + 1) / (1 + 16 + 0 + 1) × [1  -4  0  1]

y₂ = [7  -7  -6  1]  - 36/18 × [1  -4  0  1]

y₂ =  [7  -7  -6  1] - 2  × [1  -4  0  1]

y₂ =  [7  -7  -6  1] - [2  8  0  2]

y₂ = [5  1  -6  -1]

Given, four people enter an empty elevator at the first floor of a building that has 12 floors. Each person presses the button for their desired floor, and they are equally likely to want to go to floors 2 through 12 (independently of each other). the probability that the buttons for 4 consecutive floors are pressed is $\(\frac{36}{14641}$.\)

Possible cases = 9*9*9*9 = 6561

Total number of ways = 11*11*11*11

= 14,641 (since the people can choose to go to any of the 11 floors between 2 to 12, and can choose the first floor as well as the last floor, so 11*11)

So, the probability of four consecutive floors being pressed is:

Probability = $\(\frac{\text{Number of ways four consecutive floors being pressed}}{\text{Total number of ways}}$\)

Probability = $\(\frac{(9*1*1*1 + 1*9*1*1 + 1*1*9*1 + 1*1*1*9)}{14641}$\)

Probability = $\(\frac{36}{14641}$\)

So, the required probability is $\(\frac{36}{14641}$.\)

Therefore, the probability that the buttons for 4 consecutive floors are pressed is\(\frac{36}{14641}$.\)

Answer:

Step-by-step explanation:

Confidence interval for population proportion is expressed as

Sample proportion ± margin of error

Margin of error = z × √pq/n

Where

z represents the z score corresponding to the confidence level

p = sample proportion. It also means probability of success

q = probability of failure

q = 1 - p

From the information given,

Sample proportion, p = 65/100 = 0.65

q = 1 - 0.65 = 0.35

n = 200

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.025 = 0.975

The z score corresponding to the area on the z table is 1.96. Thus, the z score for a confidence level of 95% is 1.96

Margin of error = 1.96√(0.65)(0.35)/200

Margin of error = 0.066 = 6.6%

The maximum boundary of the interval is

0.65 + 0.066 = 0.716

The area of figure is 272.52 square units.

The given figure consist:

A parallelogram of,

length = 12

width   = 18

Since we know that,

Area of parallelogram  = length x width

                                      = 12 x 18

                                      = 216 square units

And it consist of a semicircle of,

radius = 12/2

          = 6

Since we know that,

Area of semicircle is = πr²/2

                                  = 3.14 x 6 x 6/2

                                  = 56.52 square units
