The probability that the player A, B, C, and D are assigned to go 1st, 2nd, 3rd, and 4th respectively is 0.0083 up to 4 decimal places.

The probability of a specific batting order for 5 players is given by the formula:

P = 1/n!

where n is the number of players and the "!" symbol represents factorial notation, which means multiplying a series of descending natural numbers.

For 5 players, the number of possible batting orders is:

n! = 5! = 5 x 4 x 3 x 2 x 1 = 120

So the probability of a specific batting order is:

P = 1/120 = 0.0083 up to 4 decimal places.

Therefore, the required probability is 0.0083 up to 4 decimal places.

The height of the billboard is approximately 13.8 feet.

From the information, there is a billboard on the top of an office building. You stand 100 feet from the base of the building and you measure the angle of elevation to the bottom of the billboard as 18°

We can use the tangent function to find x:

tan(18°) = x / 100 ft

x = 100 ft * tan(18°) ≈ 34.6 ft

tan(26°) = y / 100 ft

y = 100 ft * tan(26°) ≈ 48.4 ft

We can find the height of the billboard AB by subtracting x from y:

For the given circle, OC ⊥ AB and OC pass through the center O because it is the radius of the circle.

Consider two triangles OAC and OBC.

OC = OC = 4 units (Common side)

OA = OB = 5 units (Radii)

AC = BC (As C is the midpoint of AB)

As per the RHS rule, the ΔOAC is congruent to ΔOBC.

So, ∆OAC ≅ ∆OBC

Now, as per the RHS rule,

∠OMA = ∠OMB = 90°

Thus, conclude that OC ⊥ AB.

Since OC is the radius of the circle, and AB is a chord of the circle passing through the center, we can conclude that OC passes through the center O.

Given that tan(theta) = -7/24 and theta lies in quadrant 2, we find that sin(2theta) = 49sqrt(575)/576 using the double angle formula for sine, and the calculated values of sin(theta) and cos(theta) in the second quadrant.

We can use the fact that in quadrant 2, sine is positive and cosine is negative. Using the given value of tan(theta), we can calculate the value of sin(theta) and cos(theta), and then use the double angle formula for sine to find sin(2theta).

Let's first find sin(theta) and cos(theta):

tan(theta) = opposite / adjacent = -7/24

From the Pythagorean theorem, we know that opposite² + adjacent² = hypotenuse². We can choose a hypotenuse of 24, so that opposite is -7 and adjacent is -sqrt(24² - 7²) = -sqrt(575).

Therefore, sin(theta) = opposite/hypotenuse = -7/24 and cos(theta) = adjacent/hypotenuse = -sqrt(575)/24.

Now we can use the double angle formula for sine:

sin(2theta) = 2sin(theta)cos(theta) = 2(-7/24)(-sqrt(575)/24) = 49sqrt(575)/576.

So the exact value of sin(2theta) is 49sqrt(575)/576.

The statement "secondary data should be gathered first because this type of information is less expensive to obtain" is actually false because it has already been collected, there are some important factors to consider.

Primary data is data that is collected specifically for the purpose of the research project at hand. This type of data can include surveys, interviews, experiments, and observations. On the other hand, secondary data is data that has already been collected by someone else for a different purpose.

Firstly, it's important to consider the quality of the data. Secondary data may not always be reliable or up-to-date, which could impact the accuracy of your research findings. In some cases, you may need to spend time and resources verifying the accuracy of the secondary data, which could end up being more expensive in the long run.

Use the Empirical Rule.

The mean monthly utility bill for a sample of households in a city is $70, with a standard deviation of $8. Between what two values do about 95% of the data lie? (Assume the data set has a bell-shaped distribution.)

Given;

Mean x = $70

Standard deviation r = $8

Confidence level = 95%

To determine the range of the data, we will solve using the confidence level of 95%

Using the formula

x +/- zr/√n

Where r = standard deviation and n is the number of samples tested.

But since n is not given, and since the distribution is bell shaped and thus normal.

The emprical rule states it about 95% of the data is within 2 standard deviations from the mean.

x+/-2r

The answer to 24 times 4 is 96.

Step-by-step explanation:

To solve this, we must multiply the 4 in 24 by the 4 by itself. 4 times 4 is 16. So, the 6 is part of the answer. Place the 1 above the 2 in 24. Now, multiply 2 by 4 and add 1. You then get 9, the final number in the answer. So, the complete answer is 96.

The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16 hours.

In this case, we are estimating the difference in population means between two groups - upperclassmen and underclassmen. The point estimate is calculated by subtracting the sample mean of the underclassmen from the sample mean of the upperclassmen, which gives us

0.76 - 0.60 = 0.16.
the point estimate of the difference in population mean exercised between underclassmen and upperclassmen is 0.16 hours, which was calculated by subtracting the sample mean of underclassmen from the sample mean of upperclassmen.
Point Estimate = (Sample Mean of Upperclassmen) - (Sample Mean of Underclassmen)
Point Estimate = (0.76) - (0.60)
Point Estimate = 0.16

Hence, the point estimate of 0.16 suggests that, on average, upperclassmen exercised 0.16 hours more than underclassmen in the past 24 hours. This is a rough estimate of the difference between the two population means based on the provided sample data.

The area of the tile is: Option C: 42.5 cm².

A trapezoid is defined as a four-sided geometric shape with one pair of parallel sides. The two non-parallel sides are usually referred to as the "legs" and the other two sides are the "bases". A trapezoid can be either isosceles or non-isosceles depending on the angles of the legs. A trapezoid can also be equilateral if all four sides have equal lengths.

The formula for the area of a trapezoid is:

Area = ¹/₂ (base 1 + base 2) * height

In this case, we are given the parameters as:

Base 1 is 3 cm

Yuri has 42.86% of the original cloth left after cutting a 2 meter length from a 3.5 meter long cloth.

Percentage is a way of expressing a number as a fraction of 100, representing a portion of a whole, where 100% represents the entire amount.

Yuri originally had 3.5 meters of cloth. After cutting 2 meters of cloth, he has 3.5 - 2 = 1.5 meters of cloth left.

To find the percentage of cloth that Yuri has left, we can use the formula:

percentage = (amount left / original amount) x 100%

Plugging in the values we have

percentage = (1.5 / 3.5) x 100%

Divide the numbers

percentage = 0.4286 x 100%
