What is the sum
of the rational expressions below?

Answers

Answer:

D. 4x² - x / x² - x - 2

Step-by-step explanation:
First cross multiply then sum the results:

cross:

x(x + 2) = x² + 2x

3x(x - 1) = 3x² - 3x

sum the results of the cross:

x² + 2x + 3x² - 3x

4x² - x (this goes at the top)

Then multiply the bottom:

(x - 1 )(x + 2)

x² + 2x - x - 2

x² - x - 2 (this stays at the bottom)

Fraction ends up like:

4x² - x / x² - x - 2

males in the netherlands are the tallest, on average, in the world with an average height of centimeters (cm) (bbc news website). assume that the height of men in the netherlands is normally distributed with a mean of cm and standard deviation of cm.

Answers

The probability that a Dutch male is taller than 195 cm is  0.2525

Out of a random sample of 1000 Dutch men, people taller than 190 cm are 253 in number using statistics.

Mean = 183 cm

SD = 10.5 cm

Z score = ( Value - Mean ) /SD

Dutch male is shorter than 175 cm

Z score = ( 175 - 183)/10.5  = -0.762

from z score table   probability is  0.223

Dutch male is taller than 195 cm

Z score = ( 195 - 183)/10.5  = 1.143

from z score table   probability is  0.8735 for shorter than 195 cm

Hence probability that a Dutch male is taller than 195 cm = 1 - 0.8735

= 0.1265

Dutch male is between 173 and 193 cm  

Z score = ( 173 - 183)/10.5  = -0.952        =>  0.1705Z score = ( 193 - 183)/10.5  =  0.952         => 0.8295

0.8295 -  0.1705  =0.659

taller than 190 cm

Z score = ( 190 - 183)/10.5  = 0.6667

taller than 190 cm  = 1 -  0.7475   =  0.2525

Hence in 1000  = 252.5  = 253

Answers

The coordinates of the fourth vertex of the parallelogram are (11, -7).

What is a parallelogram?

A parallelogram is a quadrilateral with opposite sides that are parallel to each other. The opposite sides of a parallelogram are also equal in length.

The fourth vertex of a parallelogram can be determined by finding the vector that connects one vertex of the parallelogram to the opposite vertex, and then adding that vector to the third vertex given in the problem.

The vector that connects the first vertex (-3, 1) to the third vertex (5, -5) is (8, -6). To find the fourth vertex, we add this vector to the second vertex (3, -1) :

(3,-1) + (8, -6) = (11, -7)

Hence, the coordinates of the fourth vertex of the parallelogram are (11, -7).

Feedback: Incorrect. The z-score for this situation is (494 - 686) / 96 = -2. Recall that 95% of observations will fall within 2 standard deviations of mean. This means that 2.5% of observations will fall above 2 standard deviations and 2.5% of observations will fall below 2 standard deviations. This question asks for the percent of students who scored less than 494 (below 2 standard deviations). The correct answer is 2.5%.

Answers

Totally correct about the mentioned before is 2.5%. This is because the z-score for this situation is (494 - 686) / 96 = -2. According to the Empirical Rule, approximately 95% of observations will fall within 2 standard deviations of the mean. In this case, the question is asking for the percent of students who scored less than 494, which is below 2 standard deviations, so the answer is 2.5%.

SAT Math Level 2 Score

The Empirical Rule states that for a normal distribution, approximately 68% of the data will fall within one standard deviation of the mean, approximately 95% of the data will fall within two standard deviations of the mean, and approximately 99.7% of the data would get fall within 3 standard deviations of the mean. So if we know the mean and standard deviation of a normal distribution, we can use this rule to estimate the percentage of data that falls within a certain range.

In this specific question, the mean of Math Level 2 SAT subject test score was 686 with a standard deviation of 96. We were asked to find the percent of students who scored less than 494. To find this we first calculated the z-score which is (494 - 686) / 96 = -2.

Since the z-score is -2 it means that it's 2 standard deviation below the mean, and according to the Empirical rule 95% of observations will fall within 2 standard deviations of mean. This means that 2.5% of observations will fall above 2 standard deviations and 2.5% of observations will fall below 2 standard deviations. So the answer is 2.5%.

Five Seconds of Summer’s tutoring service charges a base charge of $5 and $5 per hour.

Solve the system, algebraically using substitution. Solve for both variables and box in your answers.
Choose your response to the would you rather question. Provide evidence and math to back up your choice. Could there be a scenario in which you would pick another option and tell me your other option

Answers

Answer: The cost of both services is equal when h = 2 hours.

Step-by-step explanation: The shared point on the table is when the cost of the two services is equal, i.e. when C1 = C2, where C1 is the cost of Five Seconds of Summer's service and C2 is the cost of Fall Out Boy's service.

To graphically solve the system, we can plot the two equations on the same coordinate plane. The x-axis represents the number of hours and the y-axis represents the cost. The equation for Five Seconds of Summer's service would be y = 5 + 5x and the equation for Fall Out Boy's service would be y = 9 + 3x

We can then find the point of intersection of the two lines, which represents the point at which the cost of the two services is equal. We can label this point as (x, y) and our solution.

To solve the system algebraically using substitution, we can set C1 = C2 and solve for the number of hours (h) in terms of cost.

C1 = 5 + 5h = C2 = 9 + 3h

5 + 5h = 9 + 3h

2h = 4

h = 2

So, the cost of both services is equal when h = 2 hours.

From the above result, it is clear that Fall Out Boy's service is cheaper than Five Seconds of Summer's service. For 2 hours of tutoring, the cost of Fall Out Boy's service is $9 + 3(2) = $15 and the cost of Five Seconds of Summer's service is $5 + 5(2) = $15.

However, there could be scenarios where one service is cheaper than the other depending on the number of hours of tutoring required. For example, if a student requires more than 4 hours of tutoring, Five Seconds of Summer's service would be cheaper. And if a student requires less than 2 hours of tutoring, Fall Out Boy's service would be cheaper.

In conclusion, the best option would depend on the number of hours of tutoring required, and it is best to check both options and compare the cost before making a decision

Answer:

To compare the costs of the two tutoring services, we can set up a system of equations. Let x be the number of hours of tutoring.

Five Seconds of Summer's tutoring service:

y = 5 + 5x (base charge of $5 and $5 per hour)

Fall Out Boy's tutoring service:

y = 9 + 3x (base fee of $9 and $3 per hour)

We can make a table to compare the costs of the two services at different number of hours:

Hours (x) Five Seconds of Summer (y) Fall Out Boy (y)

0                                 5                          9

1                                 10                         12

2                                 15                         15

3                                 20                         18

4                                      25                         21

The shared point in the table is when x = 0, y = 5 for Five Seconds of Summer's tutoring service and y = 9 for Fall Out Boy's tutoring service.

We can graph the two equations to compare the costs:

[Graph would be here if I were able to create one]

From the graph we can see that for any number of hours greater than 0, Five Seconds of Summer's tutoring service is cheaper.

We can also solve the system algebraically using substitution.

The random variable X is normally distributed with mean 5 and standard deviation 25. The random variable Y is defined by Y = 2 + 4X. What are the mean and the standard deviation of Y ? The mean is 20 and the standard deviation is 102.A) The mean is 20 and the standard deviation is 50.B) The mean is 22 and the standard deviation is 102.C) The mean is 22 and the standard deviation is 100.D) The mean is 22 and the standard deviation is 50.

Answers

By multiplying the mean of random variable X by two to four, the random variable Y's mean is calculated to be 20. (5). By dividing the X standard deviation (25), by 4, the standard deviation of Y is equal to 102.

The random variable X has a mean of 5 and a standard deviation of 25. A normal distribution's mean serves as its nucleus, and the standard deviation quantifies how much the values deviate from the mean. Y = 2 + 4X is the definition of the random variable Y. By adding 2 to the mean of X (5), we can determine the mean of Y, which equals 20. By dividing the standard deviation of X (25), by 4, we can determine the standard deviation of Y, which yields a standard deviation of 102 for Y. As a result, the standard deviation is 102 and the mean of Y is 20.

Climbing Mt. Everest is not an easy task! Not only is it a difficult hike, but the Earth's atmosphere
decreases exponentially as you climb above the Earth's surface, and this makes it harder to breathe. The air
pressure at the Earth's surface (sea level) is approximately 14.7 pounds per square inch (or 14.7 psi). In
Denver, Colorado, elevation 5280 feet, the air pressure is approximately 12.15 psi.

a.) write an exponential equation

b.) what is the air press at the top of mount everest, elevation 29,000 feet?

Answers

The exponential equation that represents the relationship between the air pressure and the elevation above the Earth's surface is

y = 14.7 x 0.827^x

The air pressure at the top of Mount Everest, elevation 29,000 feet is approximately 1.931 psi

Finding exponential equation and calculating air pressure

To write an exponential equation for the relationship between the air pressure and the elevation above the Earth's surface, we can use the form y = a x b^x,

where y is the air pressure,

x is the elevation,

and a and b are constants.

We can use the data given in the problem to find the values of a and b.

Let y = air pressure (psi)

x = elevation (feet)

We know that at sea level (x = 0), y = 14.7 psi

At Denver, Colorado, elevation 5280 feet, y = 12.15 psi

We can use these two points to find the values of a and b in the equation y = a x b^x

12.15 = 14.7 x b^5280

b = (12.15/14.7)^(1/5280)

b = 0.827

a = 14.7

The exponential equation that represents the relationship between the air pressure and the elevation above the Earth's surface is

y = 14.7 x 0.827^x

b.) To find the air pressure at the top of Mount Everest, elevation 29,000 feet, we can substitute that value for x into the exponential equation.

y = 14.7 x  0.827^29000

y = 1.931 psi

The air pressure at the top of Mount Everest, elevation 29,000 feet is approximately 1.931 psi. It's worth noting that this is a very low air pressure and the human body is not able to survive with such low pressure without proper equipment.
