The binomial conditions are not met as the cards are not being replaced, so the independence condition is not met. So, the correct answer is D).

The conditions for a binomial setting are

there are a fixed number of trials,

the trials are independent,

there are only two possible outcomes (success or failure),

the probability of success is constant for each trial.

In this scenario, the first two conditions are met as Lan is turning over the first four cards and they are independent events. The third condition is also met as the success is defined as observing an ace and the failure is observing any other card.

However, the fourth condition is not met as the probability of success changes for each trial. After the first card is turned over, the probability of observing an ace changes for the second trial. Therefore, the scenario does not meet all the conditions for a binomial setting. So, the correct option is D).

Answer:

  (c)  The third arc should cross the second arc.

Step-by-step explanation:

You want to know the correction required to the construction of a copy of an angle.

To copy an angle to a new vertex, arcs are drawn with the same radius at the original vertex (first arc) and the new vertex (second arc).

Then the compass is set to the length JK, and a third arc is drawn with L as the center, marking off the distance JK on the second arc.

In order do that, the third arc should cross the second arc.

Step-by-step explanation:

The standard deviation of X to be approximately 0.4852. The correct answer is option (A).

To calculate the standard deviation of X, we need to first calculate the probability of drawing a red marble on the first draw, which is 11/29. The probability of not drawing a red marble on the first draw is 18/29. The probability of drawing a red marble on the second draw, given that we did not draw a red marble on the first draw, is 11/29. Using the formula for the geometric distribution, which models the number of trials until the first success, we can calculate the expected value of X, which is 1/p, where p is the probability of success (11/29 in this case).

Therefore, the expected value of X is 29/11. To calculate the standard deviation of X, we use the formula sqrt(q/p^2), where q is the probability of failure (18/29) and p is the probability of success (11/29). Plugging in these values, we get the standard deviation of X to be approximately 0.4852.  Therefore, the correct answer is option A, 0.4852.

Using metric system, we can find that Miss Marge's fish tank holds 100 litres of water.

Everything around us has a quantitative value, from the amount of sugar you put in a cake to the size of a football pitch. Each thing is measured differently based on its length, weight, volume, or duration. With these measurements, the idea of "Metric System" is introduced. The collection of standard units designed to measure length, weight, area, and capacity is known as the metric system of measurement in mathematics. As it uses numbers in powers of 10, it is based on the decimal system.

A litre (L) and millilitres (mL) are two units for measuring capacity in the metric system. A bottle of water holds 1 Liter of water. A millilitre is about 20 drops of water.

The percentage of beds that should be specially equipped is 19.0%. The correct option is c.

To be "pretty sure" of having enough specially equipped beds, the hospital wants to have only a 5% chance of running short of these beds, even when the hospital is fully occupied. This means that the probability of having enough beds should be 95%.

Let x be the percentage of beds that should be specially equipped. Then the probability that a patient does not require a specially equipped bed is 100% - 13.95% = 86.05%.

The probability that all 258 beds are occupied by patients who do not require a specially equipped bed is (0.8605)^258 = 0.0501, which is about 5%.

Therefore, the probability that at least one patient requires a specially equipped bed is 1 - 0.0501 = 0.9499, which is about 95%.

We can set up an equation to solve for x:

0.9499 = 1 - (1 - x)^258

Solving for x, we get:

x = 19.0%

Therefore, the percentage of beds that should be specially equipped is 19.0%.

To find the volume and surface area of the composite figure, we need to first find the individual volumes and surface and the right cone, and then add them together.

The volume of a hemisphere with radius r is (2/3)πr^3, and the surface area is 2πr^2.

The volume of a right cone with radius r, height h, and slant s is (1/3)πr^2h, and the surface area is πr^2 + πrs.

In this case, the radius r and slant s are both 6 cm, and the height h of the cone can be found using the Pythagorean theorem: h = √(s^2 - r^2) = √(8^2 - 6^2) = √28 ≈ 5.29 cm.

So, the volume of the hemisphere is (2/3)π(6 cm)^3 = 72π/3 = 24π cubic cm, and the surface area is 2π(6 cm)^2 = 72π square cm.

The volume of the right cone is (1/3)π(6 cm)^2(5.29 cm) = 62.83π/3 ≈ 20.94π cubic cm, and the surface area is π(6 cm)^2 + π(6 cm)(8 cm) = 36π + 48π = 84π square cm.

Therefore, the total volume of the composite figure is 24π + 20.94π = 44.94π cubic cm, and the total surface area is 72π + 84π = 156π square cm.

After evaluating the integral ∫√(x-x²)dx, we get:

∫√u (1 - 2x) du, with the limits of integration 0 to 1/4

To evaluate the integral ∫√(x-x²)dx using the indicated table of integrals, you should look for an entry in the table that matches the given integral's form. Unfortunately, I do not have access to the specific table you are referring to. However, I can guide you on how to approach this problem.

First, you should make a substitution:

let u = x - x², then du = (1 - 2x)dx. To proceed with this substitution, you'll need to rewrite the integral in terms of 'u' and 'du'. Notice that when x = 1/2, u = 1/4.

Therefore, you can change the limits of integration as well: x = 0 corresponds to u = 0, and x = 1 corresponds to u = 0.

Now,
∫√(x-x²)dx = (1/2) ∫(1-4x+4x²-3)⁽¹/²⁾ dx

Now, we can look up the integral in the table of integrals, which indicates that:

∫(1-4x+4x²-3)⁽¹/²⁾ dx = (1/2) [ (x-1)√(1-4x+4x²) + 2arcsin(2x-1) ] + C

Therefore, substituting this result back into the original integral, we get:

∫√(x-x²)dx = (1/2) [ (x-1)√(1-4x+4x²) + 2arcsin(2x-1) ] + C

where C is the constant of integration.

A bag contains five red socks and eight blue socks. Lucky reaches into the bag and randomly selects two socks without replacement, the probability that Lucky will get different colored socks is 10/39.

We can divide the issue into two distinct possibilities and multiply them together to find a solution.

Let's start by thinking about the likelihood of choosing a red sock during the initial draw.

The likelihood of choosing a red sock on the first draw is 5/13 due to the fact that there are only five red socks among the total of thirteen socks (five red plus eight blue).

There are now twelve socks left in the bag after the first one is drawn, with four red and eight blue.

On the second draw, there is an 8/12 chance of choosing a blue sock, which is a different colour.

We add the probabilities together to determine the likelihood that both events (drawing a red sock first and a blue sock second) will occur:

(5/13) * (8/12) = 40/156 = 10/39

Therefore, the probability that Lucky will get different colored socks is 10/39.

To calculate the speed of the velociraptor, we need to divide the total distance traveled by the total time taken:

Total distance = 5m + 10m + 3m + 2m = 20m

Total time = 10 seconds

Speed = Total distance / Total time

     = 20m / 10s

     = 2m/s

To calculate the velocity of the velociraptor, we need to consider both the magnitude of its speed and its direction. We can calculate the displacement by subtracting the final position from the initial position:

Displacement = (5m [E] + 10m [W] + 3m [S] + 2m [W])

           = (5m [E] - 8m [W] + 3m [S])

           = 5m [E] - 8m [W] + 3m [S]

Note that we have used negative sign for the distance traveled towards the west.
