The equation of the line that includes CD, in slope-intercept form, is: B. y = -4/3x + 2.
How to Write the Equations of Parallel Lines and Perpendicular Lines?To write the equations of two lines that are parallel or perpendicular to each other, recall that parallel lines have the same slope (m), while perpendicular lines have slopes that are negative reciprocals.
The slope of y = 3/4x - 11 is 3/4. The negative reciprocal of 3/4 is -4/3. Therefore, the slope of AB that is perpendicular to the graph of y = 3/4x - 11 is, m = -4/3.
Since the CD is parallel to AB, then CD will have the same slope of, m = -4/3.
To write the equation of the line that includes CD, substitute m = -4/3 and (a, b) = (-6, 10) into y - b = m(x - a):
y - 10 = -4/3(x + 6)
Rewrite in slope-intercept form:
y - 10 = -4/3x - 8
y = -4/3x - 8 + 10
y = -4/3x + 2

a 50.0 cmcm, uniform, 50.0 nn shelf is supported horizontally by two vertical wires attached to the sloping ceiling (figure 1). a very small 20.0 nn tool is placed on the shelf midway between the points where the wires are attached to it.
Answers
the tension in each wire will be equal. The tension in each wire, T ,the tension in each wire is 85.36 N with its weight.
Assuming that the tool has negligible mass so that its weight does not contribute to the tension in the wires, the tension in each wire will be equal. The tension in each wire, T, can be calculated using the equation:
T = (W/2) + (L/2)*sin(θ),
where W is the weight of the shelf and L is the length of the shelf. The angle θ is the angle between the ceiling and the shelf.
In this case, W = 50 N, L = 50 cm and θ = 45°. Therefore, T = (50/2) + (50/2)*sin(45) = 50 + 35.36 = 85.36 N.

At the beginning of the year, Kaylee had $60 in savings and saved an additional $12 each week thereafter. Jack started the year with $95 and saved $5 every week. Let K represent the amount of money Kaylee has saved t weeks after the beginning of the year and let J represent the amount of money Jack has saved t weeks after the beginning of the year. Write an equation for each situation, in terms of t, and determine the number of weeks after the beginning of the year until Kaylee and Jack have the same amount of money saved.
Answers
After 5 week the savings of both Kaylee and Jack will be same.
The equation for Kaylee's savings, in terms of t, is K = 60 + 12t.
The equation for Jack's savings, in terms of t, is J = 95 + 5t.
To determine the number of weeks after the beginning of the year until Kaylee and Jack have the same amount of money saved, we set K equal to J and solve for t.
K = J
60 + 12t = 95 + 5t
7t = 35
t = 5
Kaylee and Jack have the same amount of money saved after 5 weeks.

Marcus worked 45 hours this week. His hourly rate of pay is $9.00. What was the pay
for Overtime hours only?
Answers
Marcus' overtime pay for the week is $67.50.
How is the overtime pay determined?The overtime pay is paid at the hourly rate and a half.
This translates to the regular rate of pay x 1.5 x overtime hours worked.
The total hours worked this week = 45 hours
Normal working hours per week = 40 hours (5 days x 8 hours)
Overtime hours = 5 hours (45 - 40)
Hourly rate = $9.00
Overtime rate = $13.50 ($9 x 1.5)
Overtime pay = $67.50 ($13.50 x 5)
Thus, for this week, Marcus has earned overtime pay of $67.50 above his normal weekly pay of $360.

34 In the appeal of the People v. Collins case (see Exercise 4.1.28), the counsel for the defense argued as follows: Suppose, for example, there are 5,000,000 couples in the Los Angeles area and the probability that a randomly chosen couple fits the witnesses’ description is 1/12,000,000. Then the probability that there are two such couples given that there is at least one is not at all small. Find this probability. (The California Supreme Court overturned the initial guilty verdict.)
Answers
The probability that there are two such couples given that there is at least one is 1 - (4999999/12000000) = 4/12 = 1/3.
What is probability?Probability is the measure of the likelihood that a given event will occur. It is expressed as a number between 0 and 1 (or 0% to 100%). A probability of 1 indicates that the event is certain to occur, while a probability of 0 indicates that it is impossible for the event to occur. Probability is used in a wide range of disciplines including mathematics, science, engineering, finance, and philosophy. Probability can be used to make predictions and help inform decision-making. By understanding probability, we can better understand the chances of certain outcomes and make more informed decisions.
This is because the probability that the first couple matches the description is 1/12000000, and the probability that the second couple matches the description, given that the first couple does, is 1/(12000000-1). Since there are 4999999 other couples, the probability that the second couple matches the description is (4999999/12000000). Thus, the probability that there are two such couples is 1 minus the probability that the second couple does not match the description, which is 1 - (4999999/12000000) = 4/12 = 1/3.

: A cell phone manufacturer claims that the average battery life of its newest flagship smartphone is exactly 20 hours. Javier believes the population mean battery life is less than 20 hours. He tests this claim by selecting a random sample of 33 phones of this model. Javier found that the sample mean battery life is 19.5 hours with a sample standard deviation of 1.9 hours. Should Javier reject or fail to reject the null hypothesis given the sample data below? • H:u=20 versus H, u <20 . a=0.05 (significance level) . to = -1.51 • 0.05
Answers
There is not sufficient evidence to conclude that the population mean battery life is less than 20 hours, based on the sample data.
To test the null hypothesis, Javier can use a one-sample t-test. In this test, the null hypothesis is that the population mean is equal to the claimed value of 20 hours, and the alternative hypothesis is that the population mean is less than 20 hours. To determine whether to reject or fail to reject the null hypothesis, Javier can compare the t-statistic, calculated from the sample data, to the critical t-value at a significance level of 0.05. The critical t-value is the value beyond which the null hypothesis can be rejected.
In this case, the t-statistic is given as -1.51. To find the critical t-value, Javier can use a t-table or a statistical software package. At a significance level of 0.05 and a sample size of 33, the critical t-value is approximately -1.68. Since the t-statistic (-1.51) is less than the critical t-value (-1.68), Javier should fail to reject the null hypothesis.

1. Assume that there is a party consisting of people between the ages of 18 and 24 inclusive. How many people would have to be at the party to guarantee that at least three people share the same birth date, birth month, and birth year? Note: assume the range of birth years include 2 leap years. (10 points)
Answers
at least 24 people must be in the party to guarantee that at least 3 people have the same date of birth, date of birth, date of birth.
To warrant that at least three people have the same date, month, and year of birth, we need to find the minimum number of people such that there is a probability that at least three people have the same date, month, and year. there is. Birth year she is 1 or more. Non-leap years have 365 days, and leap years have her 366 days. The birth year range includes two leap years, so there are 3652 + 3662 = 2,922 possible births. This means that the probability that a particular person's birthday is unique is (2922-1)÷2922 = 1÷2922.
Now we can use the birthday puzzle to calculate the probability that at least three people have the same birthday. The probability that no one has the same birthday is (1 - 1÷2922)^n, where n is the number of people in your party. At least he has 1-(1-1÷2922)^n probability that 3 of them have the same birthday. You can set this probability to 1 or more and solve for n.
1 - (1 - 1÷2922)^n >= 1
(1 - 1÷2922)^n <= 0
n >= log(0) ÷ log(1 - 1÷2922)
The logarithm of 0 is not defined, so you can use a small value on the right hand side instead. B. 10^-6. This will tell you:
n >= log(10^-6) ÷ log(1 - 1/2922)
n >= log(10^-6) ÷ log(2921/2922)
n >= log(10^-6) ÷ log(2921) - log(10^-6) / log(2922)
n >= log(10^-6) × log(2922) ÷ log(2921) - log(10^-6)
n >= log(10^-6) × log(2922) ÷ log(2921) - log(10^-6)
n >= 23.

We're given the equation in point-slope form: [tex]y-1=-\frac{1}{10}(x+8)[/tex], and if we want to make a line parallel to this line, we just need the slopes to be the same. So let's just look at the value in front of the parenthesis. This is given to be: [tex]-\frac{1}{10}[/tex]

Plugging the values into the point-slope formula, we get:
