The distance a swimmer will travel if they swim from one corner to the opposite corner of an Olympic-size swimming pool is approximately 62.2 meters

The distance a swimmer will travel if they swim from one corner to the opposite corner of an Olympic-size swimming pool is approximately 62.2 meters. This can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the length of the pool is one side of the right triangle, the width of the pool is the other side of the right triangle, and the distance the swimmer travels is the hypotenuse.

Using the Pythagorean theorem, we can calculate the distance the swimmer travels as follows:

a² + b² = c²

where a is the length of the pool (50 meters), b is the width of the pool (25 meters), and c is the distance the swimmer travels.

To solve for c, we can plug in the values for a and b and simplify as follows:

50² + 25² = c²

500 + 625 = c²

125 = c²√3

125 = c

Approximately 62.2 meters (rounded to one decimal place)

Therefore, the distance a swimmer will travel if they swim from one corner to the opposite corner of an Olympic-size swimming pool is approximately 62.2 meters.

Step-by-step explanation:

The percentage of data between 13.8 and 30.2 in a normally distributed data set with a mean of 22 and a standard deviation of 4.1 is approximately 94.19%.

To solve this problem, we can first standardize the values of interest using the standard normal distribution formula, z = (x - μ) / σ, where x is the value of interest, μ is the mean, and σ is the standard deviation.

For the lower value of 13.8, we have z = (13.8 - 22) / 4.1 = -1.95. For the upper value of 30.2, we have z = (30.2 - 22) / 4.1 = 2.05.

Next, we can use a calculator to find the area between these two z-scores. Alternatively, we can use the complement rule to find the area to the left of -1.95 and the area to the right of 2.05, and subtract their sum from 1.

Using a calculator, we find that the area between -1.95 and 2.05 is approximately 0.9419 or 94.19%. Therefore, approximately 94.19% of the data falls between 13.8 and 30.2 in this normally distributed data set.

After simplifying the given functiοn F=2(3+5x)+8(7-x)+4(x-1) the answer is F = 2x + 58.

In mathematics, a functiοn frοm a set X tο a set Y assigns each element οf X exactly οne element οf Y. The sets X and Y are referred tο as the functiοn's dοmain and cοdοmain, respectively.

Initially, functiοns represented the idealized relatiοnship between varied quantities and οther variables. Fοr instance, time affects a planet's pοsitiοn.

What is trigonometric ratio of tangent (tan)?

[tex] \tan( \theta) [/tex] = opposite/adjacent

Here [tex] ( \theta) [/tex] is opposite angle of base of the triangle.

The base is the side opposite to the right angle and has a length of 14 units (given).

The side opposite to the angle of 17° is the "opposite" side.

The side adjacent to the angle of 17° is the "adjacent" side.

We want to find the length of the missing side (let's call it "x"). To do this, we can use the trigonometric ratio of tangent (tan), which relates the opposite and adjacent sides:

tan(17°) = opposite/adjacent

So, tan(17°) = opposite/x

We can rearrange this equation to solve for x,

x = opposite / tan(17°)

Plugging in the values we have,

x = 14 / tan(17°)

Using a calculator, we find that tan(17°) is approximately 0.303,

So,x = 14 / 0.303 ≈ 46.2

Therefore, the missing side has a length of about 46.2 units (rounded to the nearest tenth).

The standard deviation of the mean of the 25 newborn babies is approximately 0.4 pounds, rounded to 1 decimal place.

To find the standard deviation ,we will use the formula for the standard

deviation of the sampling distribution of the sample mean:

Standard deviation of the sample mean = σ / √n

Here, σ is the population standard deviation and

n is the sample size.

Given the population standard deviation (σ) is 2 pounds and the sample size (n) is 25 newborns, we can plug in the

values into the formula:

Standard deviation of the sample mean = 2 / √25

Standard deviation of the sample mean = 2 / 5

Standard deviation of the sample mean = 0.4

Assuming the coordinates of point A are (3, 5): we would have the following results.

1. To reflect over the x-axis: the x-coordinate remains the same and the y-coordinate changes sign. So point B will have the same x-coordinate as point A (3), but the y-coordinate will be -5. Therefore, the coordinates of point B are (3, -5).

2. To reflect over the y-axis: the y-coordinate remains the same and the x-coordinate changes sign. So point C will have the same y-coordinate as point A (5), but the x-coordinate will be -3. Therefore, the coordinates of point C are (-3, 5).

3. To translate: add the given values to the x and y coordinates. So point D will have an x-coordinate of 3 + 3 = 6, and a y-coordinate of 5 + 4 = 9. Therefore, the coordinates of point D are (6, 9).

4. To rotate 180 degrees clockwise: flip the signs of both the x and y coordinates and then swap them. So point E will have an x-coordinate of -5 and a y-coordinate of -3. Therefore, the coordinates of point E are (-5, -3).

Answer:

2/5 or 0.4, which is also equivalent to a 40% chance.

Step-by-step explanation:

To determine the theoretical probability of drawing a prime number from the numbers 2 through 16, we need to first identify the prime numbers in this range. The prime numbers between 2 and 16 are 2, 3, 5, 7, 11, and 13.

There are a total of 15 numbers in the hat, and 6 of them are prime. Therefore, the probability of drawing a prime number can be calculated as:

Probability of drawing a prime number = Number of favorable outcomes / Total number of possible outcomes

Number of favorable outcomes = 6 (since there are 6 prime numbers in the range of 2 through 16)

Total number of possible outcomes = 15 (since there are 15 numbers in the hat)

So, the probability of drawing a prime number is:

Probability of drawing a prime number = 6 / 15

Simplifying this fraction by dividing both numerator and denominator by 3, we get:

Probability of drawing a prime number = 2 / 5

Therefore, the theoretical probability of drawing a prime number from the numbers 2 through 16 is 2/5 or 0.4, which is also equivalent to a 40% chance.

What is the tangent function?

The tangent function is a mathematical function that relates the ratio of the length of the side opposite to an acute angle in a right triangle to the length of the adjacent side. It is defined as the ratio of the sine of the angle to the cosine of the angle.

We can solve this problem using trigonometry. Let's call the length of the pole "x". We can then use the tangent function to relate the angle that the pole makes with the vertical to the length of the shadow cast by the pole.

The tangent of the angle between the pole and the vertical is equal to the opposite side (length of the shadow) divided by the adjacent side (length of the pole).

tan(7°) = opposite / adjacent

tan(7°) = 49 / x

We can solve for x by multiplying both sides by x and then dividing both sides by tan(7°):

x = 49 / tan(7°)

Now we know the length of the pole is:

x = 49 / tan(7°) = 412.7 ft (rounded to one decimal place)

Therefore, the length of the pole is approximately 412.7 feet.

Answer:

Therefore, the time for the return trip is:

≈ 5.306 seconds

Step-by-step explanation:

Let's start by finding the speed of the boat. We know that the boat travels 400m at a constant speed, so we can use the formula:

Speed = Distance / Time

Speed = 400m / Time (for one-way trip)

Let's assume that the time for the one-way trip is t. Then we can rewrite the speed formula as:

Speed = 400m / t

Now let's find the time for the return trip. We know that the boat travels the same route at the same speed for 2 minutes, which is equivalent to 120 seconds. This means that the distance traveled on the way back is:

Distance = Speed x Time

Distance = (400m / t) x 120 seconds

Distance = 48000m / t

We also know that when Pilar increases the boat's speed by 10 m/min, the return trip is 60 seconds faster. This means that the time for the return trip is:

t - 60 seconds

Using the same formula as before, the distance traveled on the return trip is:

Distance = (400m / (t + 1/2)) x (t - 60) seconds

Distance = (400m / (t + 1/2)) x (t - 60/60) minutes

Distance = 400m x (t - 60/60) / (t + 1/2) minutes

Now we know that the distance traveled on the way back is equal to the distance traveled on the way there:

48000m / t = 400m x (t - 60/60) / (t + 1/2)

Simplifying this equation, we get:

48 / t = 4 x (t - 1/3) / (t + 1/2)

Multiplying both sides by (t + 1/2), we get:

48(t + 1/2) / t = 4(t - 1/3)

Simplifying this equation, we get:

96 / t = 4t - 4/3

Multiplying both sides by t, we get:

96 = 4t^2 - 4/3t

Multiplying both sides by 3, we get:

288 = 12t^2 - 4t

Rearranging this equation, we get

12t^2 - 4t - 288 = 0

Dividing both sides by 4, we get:

3t^2 - t - 72 = 0

Using the quadratic formula, we can solve for t:

t = [1 ± sqrt(1 + 4(3)(72))] / 6

t = [1 ± sqrt(865)] / 6

Since t must be positive, we take the positive root:

t ≈ 6.366

Therefore, the time for the return trip is:

t - 60 seconds ≈ 6.366 - 60 seconds ≈ 5.306 seconds
