The two cars must be approximately 177.34 feet apart from each other for Spiderman to have different depression angles to each car.

To find the distance between the two cars, we can use trigonometry and the concept of similar triangles. Let's denote the distance between Spiderman and the nearest car as d1 and the distance between Spiderman and the farther car as d2.

In a right triangle formed by Spiderman, the height of the hotel, and the line of sight to the nearest car, the tangent of the depression angle (52 degrees) can be used:

tan(52) = 600 / d1

Rearranging the equation to solve for d1:

d1 = 600 / tan(52)

Similarly, in the right triangle formed by Spiderman, the height of the hotel, and the line of sight to the farther car, the tangent of the depression angle (46 degrees) can be used:

tan(46) = 600 / d2

Rearranging the equation to solve for d2:

d2 = 600 / tan(46)

Using a calculator, we can compute:

d1 ≈ 504.61 feet

d2 ≈ 681.95 feet

The distance between the two cars is the difference between d2 and d1:

Distance = d2 - d1

Plugging in the values, we have:

Distance ≈ 681.95 - 504.61

Distance ≈ 177.34 feet

The probabilities regarding the total time of the 34 jets are given as follows:

a) Less than 320 minutes: 0.9306 = 93.06%.

b) More than 275 minutes: 0.8238 = 82.38%.

c) Between 275 and 320 minutes: 0.7544 = 75.44%.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The mean and the standard deviation for the total time of the 34 jets is given as follows:

The probability that the mean is less than 320 minutes is the p-value of Z when X = 320, hence:

Z = (320 - 292.4)/18.66

Z = 1.48

Z = 1.48 has a p-value of 0.9306.

The probability that the mean is more than 275 minutes is one subtracted by the p-value of Z when X = 275, hence:

Z = (275 - 292.4)/18.66

Z = -0.93

Z = -0.93 has a p-value of 0.1762.

1 - 0.1762 = 0.8238.

The probability of a value between these two amounts is given as follows:

0.9306 - 0.1762 = 0.7544.

Four triangles can create a set of pattern blocks that includes a total of four rhombuses.

To understand why, it's essential first to understand what pattern blocks are. Pattern blocks are shapes that are commonly used in early childhood education to teach math concepts like geometry, spatial reasoning, and fractions. They come in different shapes, including triangles, squares, hexagons, trapezoids, and rhombuses.

To create a set of pattern blocks using triangles, one can use four equilateral triangles with the same side length. When these triangles are arranged together, they form a larger equilateral triangle, as each external side of each small triangle connects to a side of another triangle. This larger equilateral triangle can then be divided into four smaller rhombuses by using two diagonals (lines connecting opposite corners) to form a "X" shape. Each of these four smaller rhombuses is made up of two adjacent triangles and forms a diamond shape. Therefore, it can be said that four equilateral triangles can form a set of four rhombuses within an equilateral triangle pattern block set.

A proof by exhaustion of the theorem must prove that for every positive integer x less than 4, (x +1)^3 is greater than or equal to 4^x.

To prove the theorem by exhaustion, we must prove that for all positive integers x less than 4, (x + 1)^3 is greater than or equal to 4^x.

First, we start with x = 0. We must show that (0 + 1)^3 is greater than or equal to 4^0. We can calculate that (1)^3 = 1, which is greater than 4^0 = 1.

Next, we move to x = 1. We must show that (1 + 1)^3 is greater than or equal to 4^1. We can calculate that (2)^3 = 8, which is greater than 4^1 = 4.

Next, we move to x = 2. We must show that (2 + 1)^3 is greater than or equal to 4^2. We can calculate that (3)^3 = 27, which is greater than 4^2 = 16.

Finally, we move to x = 3. We must show that (3 + 1)^3 is greater than or equal to 4^3. We can calculate that (4)^3 = 64, which is greater than 4^3 = 64.

Answer:B.The constant of proportionality is 3. In the table the constant of proportionality is represented by the y-value when the x-value is 1. On a graph, the constant of proportionality represents the steepness of the line.

This is the answer because all of the Y's can be divided by X and equal three.

3 divided by 1 is 3, 15 divided by 5 is 3, 24 divided by 8 is 3, and 27 divided by 9 is 3.

This means that there is a constant rate, which is the proportionality,3.  This is also represented by our first X and Y value. X is 1 and Y is 3, which means that the word length increases by 3.

I hope this helped & Good Luck <3!!!!

Correct answer is B.

So this table represents a set of values related by a constant of proportionality. This constant is just the value of the slope created when the values from the "x" and "y" axis are plotted into a two-dimensional graph.

Notation: (x, y)

OP 1: (1, 3)

OP 2: (5, 15)

Slope formula: \(m=\frac{y_{2} -y_{1}}{x_{2} -x_{1} }\)

Substituting in the formula and calculating:

\(m=\frac{(15) -(3)}{(5) -(1)}\\ \\m=\frac{12}{4} \\ \\m=3\)

This value for the slope, or contant of proportionality, is enough to determine the correct answer. Correct answer is answer B.

This constant represent the relation between the word length (x) and the score (y) is 3. Therefore, each time a word length increases one time, the score increases 3 times as much.

Inside the triangle is the point of concurrency of the angle bisectors of a triangle.

A point of concurrency is an intersection of three or more lines, rays, segments, or planes, but at least three. If they coincide, then those lines or the rays are regarded as contemporaneous. You create the line segments disregarding the vertices since they must be perpendicular to the midpoint of each side. The circumcenter may be located inside or outside of the triangle as a result.

Answer:

a) 0.9959 = 99.59% probability that the mean weight is less than 9.3 ounces

b) 0.0129 = 1.29% probability that the mean weight is more than 9.0 ounces

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 8.0 ounces and a standard deviation of 1.1 ounces.

This means that \(\mu = 8, \sigma = 1.1\)

(a) If 5 potatoes are randomly selected, find the probability that the mean weight is less than 9.3 ounces?

\(n = 5\) means that \(s = \frac{1.1}{\sqrt{5}} = 0.4919\)

This probability is the pvalue of Z when X = 9.3. So

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{9.3 - 8}{0.4919}\)

\(Z = 2.64\)

\(Z = 2.64\) has a pvalue of 0.9959

0.9959 = 99.59% probability that the mean weight is less than 9.3 ounces

(b) If 6 potatoes are randomly selected, find the probability that the mean weight is more than 9.0 ounces?

\(n = 6\) means that \(s = \frac{1.1}{\sqrt{6}} = 0.4491\)

This probability is 1 subtracted by the pvalue of Z when X = 9. So

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{9 - 8}{0.4491}\)

\(Z = 2.23\)

\(Z = 2.23\) has a pvalue of 0.9871

1 - 0.9871 = 0.0129

0.0129 = 1.29% probability that the mean weight is more than 9.0 ounces

The length of the rectangle is twice its width. If its perimeter is 7 1/3 cm, its length will be 22/9 cm, and the width is 11/9 cm.

Let's assume the width of the rectangle is "b" cm.

According to the given information, the length of the rectangle is twice its width, so the length would be "2b" cm.

The formula for the perimeter of a rectangle is given by:

Perimeter = 2 * (length + width)

Substituting the given perimeter value, we have:

7 1/3 cm = 2 * (2b + b)

To simplify the calculation, let's convert 7 1/3 to an improper fraction:

7 1/3 = (3*7 + 1)/3 = 22/3

Rewriting the equation:

22/3 = 2 * (3b)

Simplifying further:

22/3 = 6b

To solve for "b," we can divide both sides by 6:

b = (22/3) / 6 = 22/18 = 11/9 cm

Therefore, the width of the rectangle is 11/9 cm.

To find the length, we can substitute the width back into the equation:

Length = 2b = 2 * (11/9) = 22/9 cm

So, the length of the rectangle is 22/9 cm, and the width is 11/9 cm.

Sphenathi and the other matriculants must travel at an average speed of approximately 107 km/h to reach Uptington by 09:45.

To determine the average speed at which Sphenathi and the other matriculants must travel to reach Uptington by 09:45, we need to calculate the time available for the journey and the distance between the two locations.

The time available is from 07:25 to 09:45, which is a total of 2 hours and 20 minutes. We need to convert this time to hours by dividing by 60:

2 hours + 20 minutes / 60 = 2.33 hours

Now, let's calculate the distance between Bloemfontein and Uptington. Suppose the distance is 'd' kilometers.

We can use the formula for average speed: average speed = distance / time

In this case, the average speed should be such that the distance divided by the time is equal to the average speed.

d / 2.33 = average speed

Now, let's assume that Sphenathi and the other matriculants must travel a distance of 250 kilometers to reach Uptington. We'll substitute this value into the equation:

250 / 2.33 = average speed

To find the average speed to the nearest km/h, we'll calculate the result:

average speed ≈ 107.3 km/h

Therefore, Sphenathi and the other matriculants must travel at an average speed of approximately 107 km/h to reach Uptington by 09:45.
