In order to achieve a bigger splash in their next trial, all the students must need to do is use a ball with a larger circumference.

Displacement and volume are defined as a dimensional object dropped into a liquid that will always displace its own volume from the liquid.

For a basketball, the circumference is a function of its volume. In other words, the larger the circumference, the larger the volume.

This defines that a basketball with a larger volume will displace more water from the pool than one with a lower volume.

Finally, to make a bigger splash, a basketball with a larger circumference would be needed.

It would be appropriate to construct a t-interval to estimate the population mean.

To determine whether it is appropriate to construct a t interval to estimate the population means, we need to consider if the sample size is large enough and if the population standard deviation is known.

If the sample size is less than 30 and the population standard deviation is not known, then it would be appropriate to use a t-interval.In this case, the sample size is 32, which is large enough to assume that the sample mean is an accurate representation of the population mean.

However, the population standard deviation is not known, so it would be appropriate to use a t interval. The t interval can be calculated using the sample mean, sample standard deviation, and degrees of freedom, which is the sample size minus 1.

The t interval will provide a range of values that we can be confident the population mean falls within, given the sample mean and variability.

The distance between the top of the ladder and the ground is decreasing at a rate of 10 meters per minute.

Let's call the distance between the bottom of the ladder and the wall as "x".

At a certain instant, x = 3636 meters

The rate of change of x with respect to time is 10 meters per minute, so dx/dt = 10 m/min.

At that same instant, the height of the ladder above the ground can be expressed as

h = (3939 - x)

since the ladder is 3939 meters long

The rate of change of h with respect to time can be found using the chain rule of differentiation.

dh/dt = dh/dx * dx/dt = -10 m/min

So, at the instant when the bottom of the ladder is 3636 meters from the wall, the rate of change of the distance between the top of the ladder and the ground is -10 meters per minute. This means that the distance between the top of the ladder and the ground is decreasing at a rate of 10 meters per minute.

The probability of drawing 5 cards from Ms Q's deck such that three cards have the same number is 876 / 98 = approximately 0.089.

There are a total of 28 possible combinations of 5 cards from Ms Q's deck since there are 4 colours and 7 numbers.

To have three cards with the same number, Yunseol must choose 3 cards with the same number and 2 cards with different numbers. There are 7 possible choices for the number of the three cards, and 4 choices for the colour of each card, so there are 7 × 4³ = 196 ways to choose the 3 cards.

For the other 2 cards, Yunseol must choose 2 different numbers and 2 different colours, so there are 7 choose 2 (or 21) ways to choose the numbers and 4 choose 2 (or 6) ways to choose the colours. Therefore, there are 21 × 6 = 126 ways to choose the other 2 cards.

So, the total number of ways to have 3 cards with the same number is 196 × 126 = 24536.

The probability of having three cards with the same number is 24536 / 28 = 876 / 98.

Therefore, the probability of drawing 5 cards from Ms Q's deck such that three cards have the same number is 876 / 98 = approximately 0.089.

The number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.

Revenue Passenger Miles (RPM) is a measure of how much passenger traffic an airline is serving, and is calculated by multiplying the number of revenue passengers (passengers paying a fare) by the distance travelled in miles. For this flight, the number of RPM is calculated as follows:

RPM = (Number of Revenue Passengers) x (Distance Travelled in Miles)

RPM = (285 Passengers) x (7,536 Miles)

RPM = 2,150,960 Miles

Let's call the time it takes for the birds to be 25 miles apart t, in hours. In this time, the first bird will fly a distance of 8t miles to the east, and the second bird will fly a distance of 6t miles to the north.

To determine t, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the distance between the birds) is equal to the sum of the squares of the other two sides.

So, for the two birds to be 25 miles apart, we have:

25^2 = (8t)^2 + (6t)^2

25^2 = 64t^2 + 36t^2

25^2 = 100t^2

t^2 = 25^2 / 100

t^2 = 0.25

t = √0.25

t = 0.5

So, it will take the birds 0.5 hours, or 30 minutes, to be 25 miles apart.

This expression represents the total number of apartments in the largest group that the study results represent, which is "all UCLA graduate student apartments in the three sampled buildings."

This is because the survey only included data from 25 apartments in each of the three randomly selected buildings. The results of the study cannot be generalized to represent all UCLA graduate student apartments or even all apartments in the group of seven buildings as the sample size is limited to only three buildings.

From the question, we have the following steps that can be used in our computation:

2x^2 - 20 = 52

2x^2 = 32x^2

16x = ±4

The error in the above steps is appending x^2 to 32 after collecting the like terms.

Also, the like terms are not properly added

The correct solution is as follows

2x^2 - 20 = 52

This is Single-Blinded Randomized Controlled trial type of study because the recipient is unaware that they are receiving a treatment, only the researchers are aware of who is receiving which treatment. So the option d is correct.

One of the most rigorous research designs is experimental research, which is frequently referred to as the "gold standard" in research designs.

This design involves the researcher manipulating one or more independent variables (as treatments), randomly assigning individuals to various treatment levels (random assignment), and observing the effects of the treatments on outcomes (dependent variables).

Experimental research has a distinct advantage in that it may link cause and effect through treatment manipulation while controlling for the erroneous effect of unrelated variables, which is known as internal validity (causality).

[tex]\frac{6x+15}{28}[/tex] = [tex]\frac{108}{48}[/tex] ( cross- multiply )

48(6x + 15) = 28 × 108 = 3024 ( divide both sides by 48 )

Scott picked x pounds of blueberries from a local farm and if Scott picked x pounds of blueberries, he now has 5 pounds, so x = 5(2) = 10 pounds.

Pounds is a unit of mass or weight used in the imperial and United States customary systems of measurement. It is equal to 16 ounces or 0.45 kilograms. In the United Kingdom and the other countries that use the imperial system of measurement, it is the standard unit used to measure the weight of people, animals and other objects. In the United States, the pound is often referred to as the avoirdupois pound to differentiate it from other units of measure.

He gave 3 pounds of his pick to his brother, Dean. This leaves x-3 pounds of blueberries. He then shared the remaining blueberries equally with his sister Georgia, so each of them got (x-3)/2 pounds of blueberries. This means that Scott has (x-3)/2 + 3 = (x+3)/2 pounds of blueberries. Therefore, if Scott picked x pounds of blueberries, he now has 5 pounds, so x = 5(2) = 10 pounds.
