how many 1/3 cubes would it take to fill a rectangular prism that is 2 1/5 m long, 5 m tall, and 3/4 m wide

According to the graph, it can be inferred that the average height of the students is 63 inches.

To find the height of the seventh grade soccer players we must analyze the graph. In this case we have a height range from 60 inches to 65 inches. However, we do not know what the individual heights of each of the players are.

The normal distribution of nail lengths with mean 5.00 in and standard deviation of 0.03 in is used to find probability of lengths less than 4.94 in and between 4.97 and 5.03 in. 58th percentile length is also determined.

a) To find the number of nails less than 4.94 in long, we need to use the cumulative distribution function of the normal distribution. Let's assume X represents the length of the nails.

We have X ~ N(5.00, 0.03^2). To find the cumulative probability of X being less than 4.94, we can use the following formula:

P(X < 4.94) = P((X - 5.00)/0.03 < (4.94 - 5.00)/0.03) = P(Z < -2.33)

Where Z is a standard normal random variable. Using a standard normal table or calculator, we find that

P(Z < -2.33) = 0.01.

So, the probability of a nail being less than 4.94 in long is 0.01, and in a bag of 120 nails, we expect 120 * 0.01 = 1.2 nails to be less than 4.94 in long.

b) To find the probability that the length of nails are between 4.97 and 5.03 in long, we can use the cumulative distribution function again. We want to find the cumulative probability of X being less than 5.03 and subtract the cumulative probability of X being less than 4.97:

[tex]P(4.97 < X < 5.03) = P(X < 5.03) - P(X < 4.97) = P((X - 5.00)/0.03 < (5.03 - 5.00)/0.03) - P((X - 5.00)/0.03 < (4.97 - 5.00)/0.03) = P(Z < 0.99) - P(Z < -0.99)[/tex]

Using a standard normal table or calculator, we find that P(Z < 0.99) = 0.84 and P(Z < -0.99) = 0.16.

So, the probability of a nail being between 4.97 and 5.03 in long is

0.84 - 0.16 = 0.68.

c) The 58th percentile of all nails represents the value below which 58% of the nails fall. We can use the inverse cumulative distribution function to find this value. Let's assume X represents the length of the nails, and P(X < x) = 0.58. We have X ~ N(5.00, 0.03^2). To find x, we can use the following formula:

x = 5.00 + 0.03 * Z

Where Z is the standard normal random variable such that  P(Z < z) = 0.58

Using a standard normal table or calculator,

we find that Z = 0.84.

So, the length of nails at the 58th percentile is 5.00 + 0.03 * 0.84 = 5.0252 in long.

A 90% confidence interval based on a sample of size 200 would be more reliable than the original 90% interval.

This is because the larger sample size gives the interval a larger margin of error, meaning the interval is more likely to contain the true population means. This is due to the greater number of data points used to calculate the mean, which reduces the possibility of outliers skewing the results.

Additionally, the larger sample size increases the power of the test, meaning that the probability of getting a statistically significant result is increased. Therefore, the 90% confidence interval based on a sample of size 200 would be more reliable than the original 90% interval.

Original price is 2.80 dollars

we take 20% of 2.80 aka the original price.

(p.s 20% in just [tex]\frac{20}{100}[/tex] since % sign means divide by 100)

so,

= [tex]2.80 * \frac{20}{100}[/tex]

The maximum number of edges in a simple undirected disconnected graph of n vertices can be any value that is less than or equal to n(n-1)/2.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

The maximum number of edges in a simple undirected disconnected graph of n vertices can be found using the formula for the maximum number of edges in an undirected graph,
E = n(n-1)/2.

However, for a disconnected graph, this formula only applies to each connected component of the graph separately. Therefore, the maximum number of edges in a simple undirected disconnected graph of n vertices is n(n-1)/2 for each connected component, so the total maximum number of edges is n₁(n₁-1)/2 + n₂(n₂-1)/2 + ... + nₐ(nₐ-1)/2, where n₁, n₂, nₐ are the number of vertices in each connected component.

So, in general, the maximum number of edges in a simple undirected disconnected graph of n vertices can be any value that is less than or equal to n(n-1)/2.

Answer:

angle 1 = 45 degrees, angle 2 = 90 degrees

Step-by-step explanation:

For angle 1:

2 of the properties of a square are that it has 4 right angles (90 degrees) and the diagonals bisect the angles.

Angle BAD = 90 degrees

Ray AC bisects angle BAC. And by definition of bisection, angle 1 = 90/2 = 45 degrees

So angle 1 = 45 degrees

For angle 2:

Angle two is an angle of triangle BAE. Angles BAE and ABE are = 45 degrees because of what is stated above for angle 1.

Since the sum of the measure of the angles in a triangle is 180. We can solve for Angle 2 by doing 180 = 45 +45+ angle 2

180 = 90 + angle 2

angle 2 = 90 degrees

It is defined as the distance traveled by an object in a certain amount of time. The unit of speed is usually meters per second (m/s) or kilometers per hour (km/h). Speed is a fundamental concept in physics, as it is a measure of the motion of objects. It is also an important concept in engineering, transportation, and many other fields. The speed of an object can be determined by dividing the distance traveled by the time taken to travel that distance.  The magnitude of speed represents the rate of change of position, and the direction indicates the direction of the change.

To find the amount of fuel used to get to the gate, we need to multiply the distance traveled by the fuel consumption per kilometer.

1. Fuel used = 392 km * 7.9 liters/100 km = 31.068 liters. Rounding to the nearest whole number, the answer is 31 liters.

The confidence interval from the first simulation is (0.564, 0.616), and the confidence interval from the second simulation is (0.615, 0.665). For the first trial, we are 95% confident the true proportion of wins with the new game strategy is between 0.564 and 0.616. For the second trial, we are 95% confident the true proportion of wins with the new game strategy is between 0.615 and 0.665 is correct.

To calculate the confidence interval, we can use the formula for a normal approximation to the binomial distribution.

The standard error of the proportion is given by the formula SE = sqrt(p(1-p)/n), where p is the proportion of wins, and n is the number of games played. The 95% confidence interval is given by p +/- 1.96 * SE.

Plugging in the values from the first simulation, we have p = 590/1000 = 0.59, and n = 1000. So, SE = sqrt(0.59(1-0.59)/1000) = 0.0242. The 95% confidence interval is 0.59 +/- 1.96 * 0.0242 = (0.564, 0.616).

Similarly, for the second simulation, p = 640/1000 = 0.64, and n = 1000. So, SE = sqrt(0.64(1-0.64)/1000) = 0.0244. The 95% confidence interval is 0.64 +/- 1.96 * 0.0244 = (0.615, 0.665).

To prove that two triangles are similar, we must show that they have the same shape, but not necessarily the same size. This can be done by showing that the corresponding angles of the two triangles are equal and that the corresponding sides are in proportion.

To do this, we can use the Side-Side-Side (SSS) Similarity Theorem. This theorem states that if all three pairs of corresponding sides of two triangles are in proportion, then the two triangles are similar. To prove this, we must show that the ratio of each pair of corresponding sides is equal.

For example, let's say we have two triangles ABC and DEF. To prove that these two triangles are similar, we must show that the ratio of AB to DE is equal to the ratio of BC to EF. We can do this by solving the following equation:

AB/DE = BC/EF

If the equation is true, then the two triangles are similar.

We can also use the Angle-Angle-Angle (AAA) Similarity Theorem to prove that two triangles are similar. This theorem states that if all three pairs of corresponding angles of two triangles are equal, then the two triangles are similar. To prove this, we must show that the measure of each pair of corresponding angles is equal.

For example, let's say we have two triangles ABC and DEF. To prove that these two triangles are similar, we must show that the measure of angle A is equal to the measure of angle D, the measure of angle B is equal to the measure of angle E, and the measure of angle C is equal to the measure of angle F.

If the measures of the corresponding angles are equal, then the two triangles are similar.
