So, approximately 28.57% of the students at the middle school play soccer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step 1: Define each variable

Let's define some variables to make the calculations easier:

t1 = the median monthly rent in 1990, which is $447

t2 = the median monthly rent in 2002, which is $658

Δ = the change in median monthly rent, which is t2 - t1

Step 2: Calculate the change in median monthly rent

Δ = t2 - t1 = $658 - $447 = $211

This means that the median monthly rent increased by $211 from 1990 to 2002.

Step 3: Divide the change by the original amount

To find the percentage increase, we need to divide the change by the original amount and multiply by 100:

Δ / t1 * 100 = ($211 / $447) * 100 = 47.2%

This means that the median monthly rent increased by 47.2% from 1990 to 2002.

Step 4: Round to the nearest tenth of a percent

The final answer is 47.2%, rounded to the nearest tenth of a percent.

The percent increase in the median monthly rent prices from 1990 to 2002 was 47.2%.

The number of times it is not land on the blue color sector is 7-1 = 6

A probability is defined as the ratio to the number of required outcomes to the total number of outcomes of an event.

The spinner is divided into 7 sectors, in which each sector is equal in size.

Among 7 sectors two of of them are blue in color.

We have to calculate that how many times the spinner not landing on the blue color sector.

For that we have to calculate the possible outcome for the blue color sector for 1 spin.

For 1 spin , the number of possible outcomes = 7.

Number of required outcomes = 2.

Probability of number of spins on blue sector for 1 spin = 2/7.

Probability of number of spins on blue sector for 7 spin = 7*(2/7) = 2.

Standard deviation = [tex]\sqrt{\frac{2}{7} *\frac{5}{7} }[/tex]= 0.4518.≅0.452.

Standard error=root(7)*0.452= 1.19≅1.2

Expected value =2-1.2 = 0.8 ≅1

Therefore the expected value is 1.

Number of times it will land on the blue color sector is 1.

Hence, the number of times it is not land on the blue color sector is 7-1 = 6.

Answer:

Cost $50.63

Step-by-step explanation:

To calculate the cost, we need to find out how many gallons of gasoline the car will consume in 450 miles. We can use the formula:

Gallons = Total miles / Miles per gallon

Gallons = 450 miles / 24 miles per gallon

Gallons = 18.75

Next, we multiply the number of gallons by the cost per gallon to get the total cost:

Total cost = Gallons * Cost per gallon

Total cost = 18.75 gallons * $2.70 per gallon

Total cost = $50.63

So, it will cost $50.63 to drive 450 miles when gasoline costs $2.70 per gallon and your car gets 24 miles per gallon.

Step-by-step explanation:

Here's a step-by-step explanation of the reflections:

Point R is located at (1, 1) on the coordinate plane.

Reflection over the y-axis: This reflection changes the sign of the x-coordinate. In other words, if the point (x, y) is reflected over the y-axis, the reflected point will be ( -x, y). So, for point R at (1, 1), the reflection over the y-axis creates R' at (-1, 1).

Reflection over the x-axis: This reflection changes the sign of the y-coordinate. In other words, if the point (x, y) is reflected over the x-axis, the reflected point will be (x, -y). So, for point R' at (-1, 1), the reflection over the x-axis creates R'' at (-1, -1).

So the final location of R'' is at the ordered pair (-1, -1).

and more generally, a side squared of a triangle is equal to the other two sides squared then added, minus double the product of the other two sides and the cosine of the opposite angle, generally denoted as the capital letter of the side. (c is the side, C is the opposite angle)

in this case the other two sides are 7 and 10, so we can say that a=7, b=10 if  it helps understand this a bit more, but "a" and "b" really just represent the other two sides.

the opposite angle is: [tex]\frac{5\pi}{13}[/tex] and the unknown is "a", but we can just express it as "c" for the sake of simplicity. Now plugging in all the known values we get the following equation:

[tex]c^2=7^2+10^2-2(7)(10)cos(\frac{5\pi}{13})\\\\c^2=49+100-140cos(\frac{5\pi}{13})\\\\c^2=149-140cos(\frac{5\pi}{13})[/tex]

Now from here we can just use a calculator to approximate the cosine, but make sure it's in radian mode! otherwise your answer may be incorrect as degrees are different than radians.

[tex]c^2=149-140(0.3546)\\\\c^2=149-49.64468\\\\c^2=99.355315814\\\\c=\sqrt{99.355315814}\\\\c=9.96771367035\\\\c\approx 9.968[/tex]

Step-by-step explanation:

To find the perimeter of a right-angled triangle when only the length of the hypotenuse is known, you'll need to use the Pythagorean theorem. Here's a step-by-step explanation:

Step 1: Understand the Pythagorean theorem

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b):

c^2 = a^2 + b^2

Step 2: Substitute the known length of the hypotenuse

Let's say the length of the hypotenuse is "h". Substitute "h" for "c" in the Pythagorean theorem:

h^2 = a^2 + b^2

Step 3: Solve for one of the unknown sides

To find the perimeter of the triangle, we need to know the lengths of both sides "a" and "b". To do this, we need to solve for one of the unknown sides. Let's solve for "a".

Square root both sides of the equation:

√(h^2) = √(a^2 + b^2)

h = √(a^2 + b^2)

Square both sides of the equation:

h^2 = a^2 + b^2

Step 4: Use the Pythagorean theorem to find the other unknown side

Now that we have an expression for "a", we can use the Pythagorean theorem again to find "b":

h^2 = a^2 + b^2

Substitute the expression for "a" that we found in Step 3 into the equation:

h^2 = (√(a^2 + b^2))^2 + b^2

h^2 = a^2 + b^2 + b^2

h^2 = 2 * b^2 + a^2

h^2 - a^2 = 2 * b^2

b^2 = (h^2 - a^2) / 2

Take the square root of both sides:

b = √((h^2 - a^2) / 2)

Step 5: Calculate the perimeter

The perimeter of the triangle is the sum of the lengths of all three sides, so we can now calculate the perimeter using the lengths of "a" and "b" that we found in Steps 3 and 4:

P = a + b + h

Step 6: Conclusion

Therefore, the perimeter of the right-angled triangle can be found by first using the Pythagorean theorem to find the lengths of two of the sides, and then adding up the lengths of all three sides to find the perimeter.

The measure of angle 1 is given as follows:

m < 1 = 42º.

To obtain the measure of angle 1 in the kite, we must consider that the consecutive angles are complementary, that is, the sum of their measures is of 90º.

Relative to angle 1, we have that:

m < 4 + m < 1 = 90º.

For the bottom left triangle, the internal angle measures are given as follows:

Considering that the sum of the measures of the internal angles of a triangle is of 180º, the measure of angle 4 is obtained as follows:

m < 4 + 42 + 90 = 180

m < 4 = 58º.

Answer:

Step-by-step explanation:

To find the two diameters that separate the top 3% and the bottom 3% of the bolts produced in the machine shop, we need to find the lower and upper bounds of the interval that contains the middle 94% of the data. This can be done using the standard normal distribution and the z-score.

First, we'll find the z-score that corresponds to the lower bound. To do this, we'll use the formula:

z = (x - μ) / σ

where x is the lower bound, μ is the mean of the data (6.48 mm), and σ is the standard deviation of the data (0.06 mm). We want to find the value of x such that the area to the left of x is equal to 3%:

z = (x - 6.48) / 0.06

z = -2.33

Next, we'll use the z-score to find the value of x (the lower bound). We'll use the standard normal distribution table to look up the value of -2.33 and find that it corresponds to a cumulative probability of 0.01. So, the lower bound is such that 1% of the data is less than or equal to this value. To find the value of x, we'll use the formula:

x = μ + zσ

x = 6.48 + (-2.33) * 0.06

x = 6.32

So, the lower bound of the interval that contains the middle 94% of the data is 6.32 millimeters. This is the diameter that separates the bottom 3% of the bolts from the rest.

Next, we'll find the upper bound in a similar way. To do this, we'll use the formula:

z = (x - μ) / σ

where x is the upper bound, μ is the mean of the data (6.48 mm), and σ is the standard deviation of the data (0.06 mm). We want to find the value of x such that the area to the left of x is equal to 97%:

z = (x - 6.48) / 0.06

z = 2.33

Using the standard normal distribution table, we find that the value of 2.33 corresponds to a cumulative probability of 0.99. So, the upper bound is such that 99% of the data is less than or equal to this value. To find the value of x, we'll use the formula:

x = μ + zσ

x = 6.48 + 2.33 * 0.06

x = 6.64

So, the upper bound of the interval that contains the middle 94% of the data is 6.64 millimeters. This is the diameter that separates the top 3% of the bolts from the rest.

Therefore, the two diameters that separate the top 3% and the bottom 3% of the bolts produced in the machine shop are 6.32 millimeters and 6.64 millimeters, rounded to the nearest hundredth.

Given that there are 26 red cards in the deck of 52 cards, the probability of obtaining a red card on any given draw is 26/52 = 1/2.

The probability of the complimentary event—the probability that no red cards are drawn in the first three draws—can be used to determine the likelihood that a red card will be pulled at least once by the third draw.

Particular that there are 26 non-red (black) cards in the 52-card deck, there is a 50% chance that no red cards will be drawn on any given draw.

As a result, the likelihood that none of the three draws will result in a red card is:

(1/2) x (1/2) x (1/2) = 1/8

The likelihood of drawing a red card at least once by the third draw is the counterpart of this probability.

The dispersion of asset prices from their average price, or market volatility, can be calculated with the use of standard deviation. A large standard deviation indicates a dangerous investment when prices move erratically. Low standard deviation indicates stable prices, which lowers the risk associated with investments.

The remaining 79 percent of pupils are not recognised if just the top 21% of students receive public recognition. Since a normal distribution is assumed, the conventional normal distribution and its corresponding z-scores can be used to provide the solution.

The percentage of scores that are higher than a certain z-score is shown by the area under the standard normal distribution to its right. Finding the z-score that represents the top 21% of scores is equivalent to locating the z-score that represents the bottom 79% of scores. By using a calculator or a table of the ordinary normal distribution, we can determine that the z-score for the bottom 79 percent of scores is roughly 0.84.

Answer:

Step-by-step explanation:

The equation that represents the town's population after 4 years can be found using the formula:

P = P0 * (1 - r)^t

Where P is the population after t years, P0 is the initial population (4.11 x 10^4), r is the annual shrink rate as a decimal (9.6% as 0.096), and t is the number of years (4).

P = 4.11 x 10^4 * (1 - 0.096)^4

P = 4.11 x 10^4 * 0.6994^4

P = 4.11 x 10^4 * 0.4139

P = 1.70 x 10^4

So the town's population after 4 years is 1.70 x 10^4.

Answer:

Let P(t) be the population of the town after t years. We know that P(0) = 4.11 x 10^4. Then, the rate of change of the population is given by -0.096P(t), so we can write the differential equation:

dP/dt = -0.096P(t)

To find the population after 4 years, we need to solve this differential equation with the initial condition P(0) = 4.11 x 10^4. We can do this by separating variables and integrating both sides:

∫(dP/P) = -0.096 ∫dt

ln|P(t)| = -0.096t + C

where C is a constant of integration that can be found using the initial condition. Solving for P(t), we get:

P(t) = Ce^(-0.096t)

where C = e^(ln|P(0)|) = e^(ln|4.11 x 10^4|) = 4.11 x 10^4

Substituting in t = 4, we get:

P(4) = 4.11 x 10^4 e^(-0.096 × 4) = 4.11 x 10^4 e^(-0.384)

So, the equation representing the town's population after 4 years is:

P(t) = 4.11 x 10^4 e^(-0.096t)

Step-by-step explanation:

When factorizing, you should always look for what each term has in common.

First, let's look at the coefficients (numbers) in each term: 1331 and 11. Both are divisible by 11, so let's factorize out 11:

1331x³y-11y³x

11(121x³y-y³x)

Looking at the terms in the bracket, we see they both have 'x's in common (121x³y has three x's multiplied in and y³x has one). Let's factorize out this x:

11(121x³y-y³x)

11x(121x²y-y³)

We can also see both terms in the brackets have 'y's in common (121x²y has one y and y³ has three multiplied in). Let's factorize out this y:

11x(121x²y-y³)

11xy(121x²-y²)

Since there is nothing in common left between the terms, we can say the expression is fully factorized!
