The solutions to the equation 2x(x + 1.5) = -1 are x = -1/2 and x = -1.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can use the distributive property to simplify the left-hand side of the equation:

2x(x + 1.5) = -1

2x^2 + 3x = -1

Now we can move all the terms to one side of the equation:

2x² + 3x + 1 = 0

This is a quadratic equation in standard form, where a = 2, b = 3, and c = 1. We can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

Plugging in the values for a, b, and c, we get:

x = (-3 ± √(3² - 4(2)(1))) / 2(2)

Simplifying this expression, we get:

x = (-3 ± √(1)) / 4

x = (-3 ± 1) / 4

x = -1/2 or x = -1

Therefore,

The solutions to the equation 2x(x + 1.5) = -1 are x = -1/2 and x = -1.

The inequality for "number t​ divided by 32 is at most 4. 25" is t/32 ≤ 4.25 and the solution is t ≤ 136

To write the word sentence as an inequality, we need to translate the words into mathematical symbols.

The phrase "a number t divided by 32" can be written as t/32. The word "is" can be translated as an equals sign, and "at most" can be translated as less than or equal to. Therefore, the word sentence "A number t divided by 32 is at most 4.25" can be written as:

t/32 ≤ 4.25

To solve the inequality, we can isolate the variable t by multiplying both sides by 32:

t ≤ 4.25 * 32

t ≤ 136

Therefore, the solution to the inequality is t is less than or equal to 136. This means that any value of t that is less than or equal to 136 will make the original inequality true. If t is greater than 136, then the inequality will be false.

Answer:

We can use the following formula for the cosine of the sum of two angles:

cos(α + β) = cos(α)cos(β) - sin(α)sin(β)

To use this formula, we need to find the values of cos(α), sin(α), cos(β), and sin(β).

Since tan(α) = 4/3 and α is in the first quadrant, we can use the Pythagorean identity to find sin(α) and cos(α):

tan^2(α) + 1 = sec^2(α)

(4/3)^2 + 1 = sec^2(α)

16/9 + 1 = sec^2(α)

25/9 = sec^2(α)

sec(α) = 3/5

cos(α) = 1/sec(α) = 5/3

sin(α) = tan(α) * cos(α) = (4/3) * (5/3) = 20/9

Since cos(β) = -4/5 and β is in the third quadrant, we can use the Pythagorean identity again to find sin(β):

sin^2(β) + cos^2(β) = 1

sin^2(β) = 1 - cos^2(β)

sin(β) = -√(1 - cos^2(β)) (since sin(β) is negative in Q3)

sin(β) = -√(1 - (-4/5)^2) = -√(1 - 16/25) = -√(9/25) = -3/5

Now we can substitute these values into the formula for cos(α+β):

cos(α + β) = cos(α)cos(β) - sin(α)sin(β)

cos(α + β) = (5/3) * (-4/5) - (20/9) * (-3/5)

cos(α + β) = -4/3 + 4/3

cos(α + β) = 0

Therefore, cos(α+β) = 0.

A sample size of at least 1,521 Internet users would be necessary to estimate the proportion of interest (the proportion of Internet users who are willing to pay fees for website access) to within 2 percent in a 95 percent confidence interval.

To calculate the sample size required to estimate a proportion with a certain level of confidence and margin of error, we can use the following formula:

[tex]n = (Z^2 \times p \times (1 - p)) / E^2[/tex]

where:

n is the required sample size

Z is the Z-score for the desired level of confidence (95% confidence corresponds to a Z-score of 1.96)

p is the estimated proportion of interest (the proportion of Internet users who are willing to pay fees for website access)

E is the desired margin of error (2% in this case, expressed as a decimal)

We are given that out of a sample of 13,000 Internet users surveyed in 1995, 2,938 were definitely not willing to pay fees for website access. This means that the proportion of interest (p) is:

p = (13,000 - 2,938) / 13,000 = 0.774

Now we can plug in the values and solve for n:

[tex]n = (1.96^2 \times 0.774 \times (1 - 0.774)) / 0.02^2[/tex]

P(A and B) is not equal to P(A) * P(B), we can conclude that events A and B are dependent.

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

We can determine if events A and B are independent or dependent by comparing the probability of both events occurring together with the product of their individual probabilities.

P(A and B) = 1/7

P(A) = 2/3

P(B) = 3/7

If A and B are independent events, then P(A and B) = P(A) * P(B). However, in this case, P(A and B) is not equal to P(A) * P(B):

P(A) * P(B) = (2/3) * (3/7) = 2/7

Since P(A and B) is not equal to P(A) * P(B), we can conclude that events A and B are dependent.

Events A and B are dependent since the probability of their intersection is not equal to the product of their individual probabilities. Specifically, P(A and B) = 1/7 while P(A)*P(B) = 2/7.

Therefore, P(A and B) is not equal to P(A) * P(B), we can conclude that events A and B are dependent.

The statement " Each neighborhood in DMR encompasses just the vertices and edges of a bad triangle" is false because a neighborhood in a Delaunay triangulation typically encompasses more than just the vertices and edges of a single bad triangle.

The statement is incorrect. A "bad triangle" refers to a specific type of triangle that can occur in a Delaunay triangulation, which is a type of triangulation used in computational geometry. A bad triangle is a triangle that violates the Delaunay condition, which requires that the circumcircle of the triangle contains no other vertices of the triangulation.

While a Delaunay triangulation can be used to partition a set of points into a set of triangles, each neighborhood in the triangulation typically encompasses more than just the vertices and edges of a single bad triangle. Instead, a neighborhood typically encompasses all of the triangles in the triangulation that share a common vertex or edge with a given triangle.

Answer: 274 degrees.

Step-by-step explanation:

If the temperature in an oven increases by 8 degrees every minute, then in 3 minutes the temperature will increase by 8 x 3 = 24 degrees.

Therefore, the temperature in the oven after 3 minutes will be:

250 + 24 = 274 degrees.

Therefore, the temperature at the summit of the 3,000-foot mountain on a sunny day is estimated to be 10.8 F°.

In mathematics, an equation is a statement that indicates the equality of two expressions. An equation typically contains one or more variables, which are placeholders for unknown values or quantities. The variables can take on different values, and the goal is often to find the values that satisfy the equation.

Here,

Let's start by calculating the rate of change of temperature with respect to elevation:

=-5.4 F° / 1,000 ft

This means that for every 1,000-foot increase in elevation, the temperature will decrease by 5.4 F°.

Next, we can calculate how much the temperature will decrease from the base of the mountain to the summit:

3,000 ft / 1,000 ft = 3

This means that the elevation difference between the base of the mountain and the summit is 3,000 - 0 = 3,000 ft.

So, the temperature decrease from the base to the summit is:

-5.4 F° / 1,000 ft * 3,000 ft = -16.2 F°

This means that the temperature at the summit will be:

27 F° - 16.2 F° = 10.8 F°

The number of tellers that should be used if the aim is to keep the mean queuing time to less than 5 minutes is 3.

To determine the number of tellers follow these steps:

1. Arrival rate (λ) = 18 customers per hour
2. Mean service time (μ) = 10 minutes per customer = 1/6 customer per minute
3. Lobby capacity = 15 customers
4. Target mean queuing time = 5 minutes

Now, calculate the service rate and find the number of tellers needed to achieve the target mean queueing time.

Step 1: Convert arrival rate to customers per minute: λ = 18/60 = 0.3 customers per minute
Step 2: Calculate the service rate per teller: 1/μ = 1/(1/6) = 6 customers per hour = 0.1 customers per minute
Step 3: Determine the number of tellers (n) needed to achieve the target queuing time:

Using the formula:
n > λ / (μ * (Wq_target + 1/μ))

Here, Wq_target is the target mean queuing time in minutes.
n > 0.3 / (0.1 * (5/60 + 1/(6/60)))

After solving the inequality, we get:

The sample points of events A, B, A ∩ B, A ∪ B and A' (complement of A) are given. The probability of event are 1/18, 11/36, 1/18, 7/18 and 17/18 respectively. The probability using additive rule of p(A ∩ B) is 1/36.  Events A and B are not mutually exclusive as they have a non-empty intersection.

Sample points in the events

A' (complement of A): {(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3), (5, 1), (5, 3), (5, 5), (6, 2), (6, 3), (6, 5), (1, 5), (1, 6), (2, 6), (3, 5), (3, 6), (5, 6), (6, 6)}

The probability of event A is

p(A) = 2/36 = 1/18.

The probability of event B is

p(B) = 11/36.

The probability of event

A ∩ B (i.e., A and B) is p(A ∩ B) = 2/36 = 1/18.

The probability of event

A ∪ B (i.e., A or B) is p(A ∪ B) = 14/36 = 7/18.

The probability of event A' (i.e., not A) is p(A') = 17/18.

By the additive rule, we have p(A ∪ B) = p(A) + p(B) - p(A ∩ B). Therefore, p(A ∩ B) = p(A) + p(B) - p(A ∪ B) = (1/18) + (11/36) - (7/18) = 1/36. This inconsistent with the answer we obtained in above part.

Answer: Thomas swims 50,000 meters in 5 weeks.

Step-by-step explanation: To determine the total distance swam by an individual over a period of 5 weeks, the product of their weekly swim distance can be calculated by multiplying said distance by 5.

The accumulated distance covered within a period of five weeks by an individual with a weekly average of 10,000 meters amounts to a total distance of 50,000 meters.

Thomas swims 50,000 meters in 5 weeks.

Thomas swims 10 kilometers each week. To convert kilometers to meters, we multiply by 1,000 because there are 1,000 meters in a kilometer.

10 km * 1,000 meters/km = 10,000 meters

Thomas swims 10,000 meters each week. Now, to find out how many meters he swims in 5 weeks, we multiply the weekly distance by the number of weeks:

10,000 meters/week * 5 weeks = 50,000 meters

The compound inequality that has no solution is d) m + 9 < 8 and -2m ≥ 10.

A compound inequality combines two or more inequalities using the logical connectives "and" or "or".

Compound inequalities are used to describe a range of values that satisfy multiple conditions simultaneously.

In the given compound inequality, the first inequality states that m + 9 is less than 8, which can be rewritten as m < -1.

The second inequality states that -2m is greater than or equal to 10, which can be rewritten as -2m ≥ 10.

However, the two inequalities cannot be true at the same time because if m is less than -1, then -2m would be greater than 2, and therefore cannot be greater than or equal to 10.

So there is no value of m that satisfies both inequalities simultaneously, resulting in no solution.
