Step-by-step explanation:

As per the given distance, the bus and the motorcycle will pass each other at 4:50 pm.

Now, let's find the distance the bus travels during that time. We know the speed of the bus is 60 mph, so we can use the formula distance = speed x time. Thus, the distance the bus travels is:

distance = speed x time

distance = 60 x t

Next, let's find the distance the motorcycle travels during the same time. The speed of the motorcycle is 72 mph, so we can use the same formula to find the distance the motorcycle travels:

distance = speed x time

distance = 72 x (t - 3/4)

Here, we subtract 3/4 from the time because the motorcycle leaves 45 minutes later than the bus. Remember, we need to convert 45 minutes to hours by dividing it by 60. Therefore, 45 minutes is equal to 3/4 of an hour.

Now that we have both distances, we can set them equal to each other since the bus and the motorcycle will meet at the same point in time:

60t = 72(t - 3/4)

Let's simplify and solve for "t":

60t = 72t - 54

12t = 54

t = 4.5

Therefore, it will take 4.5 hours for the bus and the motorcycle to meet each other. But, we need to find out what time that will be. We know the bus left at 12:20 pm, so we add 4.5 hours to that time:

12:20 pm + 4.5 hours = 4:50 pm

The “yearly tuition costs” as an independent variable which should be plotted on X-axis and “mid-career salary” as a dependent variable on Y-axis. The scatterplot is made of them.

Based on the table provided, it is possible to observe that there is not necessarily a clear relationship between the cost of tuition and mid-career salary.

While some of the colleges with higher tuition costs (such as MIT and Stanford) have high mid-career salaries, others (such as Harvey Mudd and Caltech) also have high mid-career salaries despite lower tuition costs. Additionally, some colleges with low or zero tuition costs (such as the US Naval Academy and West Point) also have high mid-career salaries.

Therefore, it is not safe to assume that a higher cost of tuition will necessarily translate into higher-paying jobs. The scatter plot of yearly tuition costs and mid-career salary is made.

To determine how much you should expect to pay for gas in Philadelphia versus Cleveland, we need to compare the transportation expenses in both cities. Based on the given data, the transportation expenses are as follows:

Philadelphia: $117

Cleveland: $106

To calculate the expected gas prices, we need to consider the transportation expenses relative to the national average. The formula to find the expected gas price is:

Expected Gas Price = National Average * (Transportation Expense / National Average)

National Average for gas = $2.59

For Philadelphia:

Expected Gas Price in Philadelphia = $2.59 * ($117 / 92) ≈ $3.30

For Cleveland:

Expected Gas Price in Cleveland = $2.59 * ($106 / 78) ≈ $3.51

Comparing the expected gas prices, we find that:

A. $3.03 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

B. $1.95 / $2.59: This option does not match the expected gas prices in Philadelphia and Cleveland.

C. $2.34 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

D. $2.75 / $3.24: This option matches the expected gas prices in Philadelphia and Cleveland.

Therefore, the correct answer is:

D. $2.75 / $3.24

The proportion null hypothesis is a specific type of hypothesis that tests for significant differences in proportions between two groups.

In statistics, a hypothesis is a statement that is being tested through data analysis. The null hypothesis is a specific type of hypothesis that assumes there is no significant difference or relationship between two variables being studied. The proportion null hypothesis specifically applies to situations where the variable being studied is a proportion or percentage.

The proportion null hypothesis states that there is no significant difference in the proportions of two groups being compared. This can be represented mathematically as

H0 => p1 = p2, where H0 represents the null hypothesis, p1 represents the proportion in the first group, and p2 represents the proportion in the second group.

To test this hypothesis, researchers will collect data from both groups and calculate the proportion for each group. They will then use statistical tests to determine whether the difference in proportions is significant or could have occurred by chance. If the difference is not significant, then the null hypothesis is accepted, and it can be concluded that there is no real difference in the proportions of the two groups.

It is important to note that the proportion null hypothesis is just one type of hypothesis that can be tested in statistics.

Converting complex numbers from rectangular form (a + bi) to polar form (r∠θ), we get A = √13 ∠ 56.3° in polar form.

we use the following formulas:

r = √(a^2 + b^2)
θ = tan^-1(b/a)

For D = 1 - j2:
a = 1, b = -2
r = √(1^2 + (-2)^2) = √5
θ = tan^-1(-2/1) = -63.4° (or 296.6° in polar coordinates)

Therefore, D = √5∠296.6° in polar form.

For A = 2 + j3:
a = 2, b = 3
r = √(2^2 + 3^2) = √13
θ = tan^-1(3/2) = 56.3°


To convert the complex numbers D = 1 - j2 and A = 2 + j3 to polar form, we first find their magnitudes (r) and angles (θ) using the formulas:

r = √(x^2 + y^2)
θ = arctan(y/x)

For D (1 - j2):
r_D = √((1)^2 + (-2)^2) = √(1 + 4) = √5
θ_D = arctan((-2)/1) = -63.4° (approx.)

So, D in polar form is: D = √5 ∠ -63.4°

For A (2 + j3):
r_A = √((2)^2 + (3)^2) = √(4 + 9) = √13
θ_A = arctan(3/2) = 56.3° (approx.)

So, A in polar form is: A = √13 ∠ 56.3°

When finding a parallel equation to y=mx+b, mx will always stay the same. So we have to find b.

In order to do this you plug the parallel lines passing point into the equation.

-5(y) goes into the y's spot. 4(x) goes into the x's spot.

-5 = 3 x 4 + b

Answer: negative correlation; yes

The partial derivatives are:

∂ z / ∂ x = − [ 5x⁴z⁶ ] / [ 6x⁵z⁵ + 6z⁵y⁴cos ( y⁴z⁶ )]

∂ z / ∂ y  = − [ 4y³z⁶ cos ( y⁴ z⁶ ) ] / [ 6x⁵z⁵ + 6z⁵y⁴cos ( y⁴z⁶ )]

We have,

f(x, y, z) = x⁵z⁶ + sin (y⁴z⁶) + 2 = 0

Now, partially differentiating we get

∂ z / ∂ x

= - [ ∂ F / ∂ x ] /  [ ∂ F / ∂ z  ]

If the null hypothesis is true and there is no treatment effect, the expected value on average for the F-ratio would be 1.00. The correct answer is option (b) 1.00

In hypothesis testing using the F-test, the F-ratio is calculated by dividing the variance between groups (treatment effect) by the variance within groups (random variation). When the null hypothesis is true and there is no treatment effect, the numerator (variance between groups) and the denominator (variance within groups) would be similar, resulting in an F-ratio close to 1.

Therefore, the correct answer is b. 1.00, as the expected value for the F-ratio would be around 1 when the null hypothesis is true and there is no treatment effect.

Answer:

The distributive property is used when finding the product of two polynomials by distributing one polynomial to each term of the other polynomial. For example, if we wanted to multiply (3x - 4)(2x + 5), we would use the distributive property by first multiplying 3x(-4) and 2x(5) and then adding the results together.

Polynomials are closed under multiplication, meaning that when two polynomials are multiplied together, the result is always another polynomial. This is true because a polynomial is a combination of constants and variables raised to non-negative integer powers, and when two polynomials are multiplied, the result is a combination of constants and variables raised to non-negative integer powers, which is a polynomial.

ANSWER :

∠D = y = 65 and ∠F = x = 45

Step-by-step explanation:

The mean distance that the ball was thrown is approximately 38.92/12 = 3.24 feet.

To find the mean distance that the heavy ball was thrown, we need to calculate the sum of all the distances and then divide by the total number of throws:

(20+25+25+31+33+34+41+41+45+50+56+67)/12 = 467/12 ≈ 38.92

So, the mean distance that the ball was thrown is approximately 38.92/12 = 3.24 feet.

This means that on average, the ball was thrown a distance of 3.24 feet. However, it's important to note that the mean can be influenced by outliers, which in this case is the one throw of 6.7 feet.

So, while the mean is a useful measure of central tendency, it's important to also consider other measures such as the median and mode to get a complete picture of the data.

The mean is the sum of all the values in a dataset divided by the total number of values. It provides an estimate of the central location of the data and can be a useful summary statistic for describing a dataset. However, the mean can be influenced by outliers, which are values that are significantly different from the rest of the data.

In this case, the one throw of 6.7 feet is an outlier because it is much further than any other throw, and it will increase the mean value.

For this reason, it's important to consider other measures of central tendency such as the median and mode. The median is the middle value in a dataset, and it's not affected by outliers. The mode is the value that appears most frequently in a dataset and can provide useful information about the typical or most common value in the data.

By considering all three measures (mean, median, and mode), we can get a more complete picture of the data and make better inferences or conclusions about it.
