Answers
The required, two expressions are not equivalent, and Pat's claim is false.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.
Here,
a) To show that Pat is wrong, we can substitute p = 3 into both expressions and compare the results:
4 - (p + p + p) = 4 - (3 + 3 + 3) = 4 - 9 = -5
4 - p + p + p = 4 - 3 + 3 + 3 = 7
Since the two expressions have different values when p = 3, Pat's claim is false.
b) Simplifying each expression algebraically, we have:

Assignment 2: Please use the IQ data below and assess whether any of the IQ scores are statistically significantly high or low. Please provide corresponding z-score and percent of scores below from the table in the book. That is, you will need to provide the percent of all scores that falls BELOW the z-score you calculate (see z table in back of book gives you this percent). This is often referred to as the percentile rank.
Also, you will need to discuss whether each z- score meets the criteria of “statistically significant” and why. Please use your book to help with this part. While "statistical significance" is determined by an arbitrary score on the z-table, there is a score one must cross to be considered significant (.05 percent for example).
IQ Scores: 100, 90, 110, 160, 90, 85, 65, 100, 95, 98
Answers
The statistical significance does not necessarily imply practical significance. In this case, while the IQ score of 160 is statistically significant, it may not necessarily be practically
What is corresponding z-score and percent of scoreTo assess whether any of the IQ scores are statistically significantly high or low, we need to calculate the z-score for each score. The formula for calculating the z-score is:
z = (x - μ) / σ
Where x is the IQ score, μ is the mean IQ score, and σ is the standard deviation of IQ scores.
First, we need to calculate the mean and standard deviation of the IQ scores:
Mean = (100 + 90 + 110 + 160 + 90 + 85 + 65 + 100 + 95 + 98) / 10 = 99.3
Standard deviation = √[((100-99.3)² + (90-99.3)² + (110-99.3)² + (160-99.3)² + (90-99.3)² + (85-99.3)² + (65-99.3)² + (100-99.3)² + (95-99.3)² + (98-99.3)²) / 10] = 39.77
Now we can calculate the z-score for each IQ score:
z1 = (100 - 99.3) / 39.77 = 0.018
z2 = (90 - 99.3) / 39.77 = -0.233
z3 = (110 - 99.3) / 39.77 = 0.27
z4 = (160 - 99.3) / 39.77 = 1.53
z5 = (90 - 99.3) / 39.77 = -0.23
z6 = (85 - 99.3) / 39.77 = -0.36
z7 = (65 - 99.3) / 39.77 = -0.86
z8 = (100 - 99.3) / 39.77 = 0.017
z9 = (95 - 99.3) / 39.77 = -0.108
z10 = (98 - 99.3) / 39.77 = 0.032
Using the z-table, we can find the percent of scores below each z-score:
z1 = 0.018 or 70.01%
z2 = -0.233 or 34.67%
z3 = 0.27 or 75.01%
z4 = 1.53 or 83.68%
z5 = -0.23 or 34.67%
z6 = -0.36 or 37.47%
z7 = -0.86 or 45.16%
z8 = 0.017 or 70.01%
z9 = -0.108 or 31.80%
z10 = 0.032 or 69.15%
To determine whether each z-score is statistically significant, we need to compare it to a predetermined level of significance, typically α = 0.05. If the probability associated with the z-score (i.e., the percent of scores below it) is less than or equal to α, we consider the score statistically significant.
Based on this criterion, the only score that is statistically significant is the IQ score of 160 (z-score = 2.29, percent of scores below = 83.68%). All other scores have a probability greater than α, and therefore are not statistically significant.

The angle between A = (25 m)i +(45 m)j, and the positive e axis is
Answers
Therefore, the angle between vector A and the positive e axis (which is the positive x-axis) is 60.255°.
To find the angle between vector A = (25 m)i + (45 m)j and the positive e axis, we first need to find the direction of vector A.
We can find the direction of vector A by taking the arctangent of the y-component over the x-component of the vector:
θ = tan⁻¹ (y/x)
where θ is the angle between the vector and the positive x-axis.
In this case, the y-component of vector A is 45 m and the x-component is 25 m:

Answers
Answer:
Assuming "she" in the question is a typo and it should be "if", here's the solution:
If the population of a small town is 567, and it decreases at a rate of 1.5% per year, we can find the population after 20 years using the formula:
P = 567 * (1 - 0.015)^20
where P is the population after 20 years.
Simplifying this expression, we get:
P = 567 * 0.742 = 420.414
Rounding this to the nearest whole number, we get:
P ≈ 420
Therefore, after 20 years, the population of the small town would be approximately 420.

Answers
The sale price per sheet in this example is $12.60.
What is the discount?
A discount is a reduction in the price of a product or service that is offered by a seller to a buyer. It is a form of incentive that is used to encourage customers to purchase goods or services, often by making them more affordable or attractive.
To compare the two deals, we need to calculate the sale price per sheet for each deal.
In the previous example, the sale price per sheet was $15.00 after a 20% discount off the regular price of $18.00.
In this example, the sale price per sheet is 30% off the regular price of $18.00, so we can calculate the sale price per sheet as:
Sale price per sheet = Regular price per sheet - Discount amount
Sale price per sheet = $18.00 - (30% x $18.00)
Sale price per sheet = $18.00 - $5.40
Sale price per sheet = $12.60
Comparing the two deals, we can see that the sale price per sheet in this example is lower than the sale price per sheet in the previous example. Therefore, the better deal is the 30% discount off the regular price of $18.00, which results in a sale price per sheet of $12.60.
Therefore, the sale price per sheet in this example is $12.60.

75x+30y=1500. Solve for x and y
Answers
For the equation 75x+30y=1500, x is (100 - 2y) / 5 and y is (100 - 5x) / 2.
Describe Equation?An equation is a mathematical statement that uses symbols and numbers to express a relationship between two or more variables. It states that two expressions are equal to each other.
We can solve for x and y in the equation 75x + 30y = 1500 by using algebraic manipulation.
First, we can simplify the equation by dividing both sides by the greatest common factor of 75 and 30, which is 15:
(75x + 30y) / 15 = 1500 / 15
Simplifying the left side gives:
5x + 2y = 100
Next, we can isolate one of the variables. Let's isolate y by subtracting 5x from both sides:
5x + 2y - 5x = 100 - 5x
Simplifying the left side gives:
2y = 100 - 5x
by dividing both sides by 2:
y = (100 - 5x) / 2
This is the equation for y in terms of x. We can use this equation to solve for y given a value of x, or we can substitute it back into the original equation to solve for x in terms of y.
Let's solve for x in terms of y by isolating x in the equation 5x + 2y = 100:
5x = 100 - 2y
Dividing both sides by 5 gives:
x = (100 - 2y) / 5
This is the equation for x in terms of y. We can use this equation to solve for x given a value of y, or we can substitute it back into the original equation to solve for y in terms of x.

What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.

We have been given that cost of one cap is $6, so cost of x caps will be equal to 6x.
We are also told that the company charges an amount of $25 for shipping, so total cost of buying x caps will be equal to the cost of x caps plus shipping charges (6x+25).
Since Laura has a budget of $1,000, so cost of x caps will be less than or equal to 1,000.
We can represent this information in an equation as:
6x+25≤1000
Let us solve for x
Subtract 25 from both sides
6x≤1000-25
6x≤975
Divide both sides by 6

Given: Members of a lacrosse team raised $2412.50 to go to a tournament. They rented a bus for $1072.50 and budgeted $67 per player for meals.
we have to determine the number of players the team can bring to the tournament.
So to make an equation, the bus charge would be the y-intercept (If no member went, they still paid for the bus fee) and the meals would be the slope (since it is dependent on how many members ride the bus.)
The total would add up to be 2412.50, so the equation would be:
2412.50 = 67x+1072.50
where x = the number of players the team can bring to the tournament without going outside of their budget.
After solving this, we get
2412.50 = 67x+1072.50
2412.50 - 1072.50 = 67x
1340 = 67x
x = 20

Enter your answer in the blank.
Answers
We know that 50% of the data falls between the minimum value and the median (i.e., between 5 and 35). So the answer is: 50%.
Describe Median?The median is a useful measure of central tendency in datasets that are skewed or have outliers, as it is less sensitive to extreme values than the mean. It is also useful in datasets with non-numeric values, such as rankings or survey responses. In addition to the median, other measures of central tendency include the mean and mode. Each measure has its own strengths and weaknesses, and the appropriate measure to use depends on the nature of the dataset and the research question being asked.
To answer this question, we need to determine the position of the lower whisker and the vertical bar relative to the range of the data.
The lower whisker extends to 5, which is the minimum value in the dataset. The vertical bar inside the box is located at 35, which represents the median of the dataset.
Therefore, we know that 50% of the data falls between the minimum value and the median (i.e., between 5 and 35).
