A triangle has an area of 144 square feet. The height is 24 feet. What is the length of the base (in feet)?

Answers

Answer 1
We can use the formula for the area of a triangle to solve for the length of the base:

Area = (1/2) x base x height

We know that the area is 144 square feet and the height is 24 feet, so we can substitute those values into the formula:

144 = (1/2) x base x 24

To solve for the length of the base, we can first simplify the right-hand side of the equation:

144 = 12 x base

Dividing both sides by 12, we get:

12 = base

Therefore, the length of the base of the triangle is 12 feet.

where:

y is the dependent variable (or response variable)

x is the independent variable (or predictor variable)

a is the intercept (the value of y when x = 0)

b is the slope (the change in y for a unit change in x)

To create the correct equation of the estimated population regression line, Sonny should select the following options:

The variable y should be the dependent variable (or response variable).

Determine the number of elements of a set and represent the number of elements using a symbol

Answers

We can represent the number of elements in a set using the symbol |A| or n(A). So, we can say |A| = 5 or n(A) = 5. We can make generalizations about the equality of sets based on the definition above.

What is set?

In mathematics, a set is a collection of distinct objects, which can be anything such as numbers, letters, or other mathematical objects. These objects are called the elements or members of the set. Sets can be defined using various methods such as listing the elements, describing properties of the elements, or using set-builder notation. For example, we can define the set of even numbers using set-builder notation as {x | x is an integer and x is divisible by 2}. Sets play a fundamental role in various branches of mathematics, including algebra, geometry, and analysis. They are used to define mathematical structures such as groups, rings, and fields, and to study various mathematical concepts such as functions, relations, and cardinality.

Here,

11.1.4 To determine the number of elements of a set, you need to count the number of distinct elements in the set. For example, if you have a set A = {1, 2, 3, 4, 5}, then the number of elements in set A is 5.

11.1.5 Two sets are equal if they have exactly the same elements. For example, if we have set A = {1, 2, 3} and set B = {3, 2, 1}, then A and B are equal sets because they contain the same elements, even though the order of the elements is different. We can write this as A = B. If two sets are not equal, then we use the symbol ≠ to denote inequality. For example, if set A = {1, 2, 3} and set B = {4, 5, 6}, then A ≠ B.

Some of these generalizations are:

Two sets are equal if and only if they have the same elements.

The order of the elements in a set does not matter for equality.

If two sets have different elements, then they are not equal.

If two sets have the same elements, but with different multiplicities, then they are not equal.

Find the maximum/minimum value of the quadratic function q² + 22q = y - 85 by
completing the square method.

O-48
C

-64

Answers

Step-by-step explanation:

To find the maximum/minimum value of the quadratic function q² + 22q = y - 85, we can complete the square as follows:

q² + 22q = y - 85

q² + 22q + 121 = y - 85 + 121 (adding (22/2)² = 121 to both sides)

(q + 11)² = y + 36

Now, we have a square of a binomial on the left side, which means the minimum value of the quadratic function is y + 36, and it occurs when (q + 11) = 0. Thus, the minimum value is:

y + 36 = 36 - 85 = -49

Similarly, the maximum value of the quadratic function occurs when (q + 11) = 0, but this time the value of y will be as large as possible. The largest possible value of y occurs when STU is a permutation of the digits 9, 8, and 7 (since PQR must be 4, 0, and 3 in some order). Thus, the maximum value is:

y + 36 = 9 + 8 + 7 - 85 + 36 = -25

Therefore, the options are incorrect and the correct answers are:

Minimum value: -49

Maximum value: -25

Answers

Where the above Terms exists, the amount to be paid in each of the above invoices are given as follows;

Invoice 1: $7,840Invoice 2: $24,255Invoice 3: $80,190Invoice 4: $16,975.

How would one define the the Terms above?

Note that the terms are defined as follows;

Terms A: 2/10, n/60 (2% discount if paid within 10 days, net due in 60 days)

Terms B: 1/15, EOM (1% discount if paid within 15 days, end of month terms)

Terms C: 1/10, n/30 (1% discount if paid within 10 days, net due in 30 days)

Terms D: 3/15, n/45 (3% discount if paid within 15 days, net due in 45 days.

So to compute the amount to be paid for each of the four separate invoices assuming that all invoices are paid within the discount period, we need to calculate the amount of the discount and subtract it from the gross merchandise amount.

For terms 2/10, n/60:

Discount = 2% of $8,000 = $160

Amount to be paid = $8,000 - $160
= $7,840



For terms 1/15, EOM:

Discount = 1% of $24,500 = $245

Amount to be paid = $24,500 - $245
= $24,255



For terms 1/10, n/30:

Discount = 1% of $81,000 = $810

Amount to be paid = $81,000 - $810
= $80,190



For terms 3/15, n/45:

Discount = 3% of $17,500 = $525

Amount to be paid = $17,500 - $525
= $16,975


Therefore, the amount to be paid for each of the four separate invoices assuming that all invoices are paid within the discount period are:

Invoice 1: $7,840Invoice 2: $24,255Invoice 3: $80,190Invoice 4: $16,975

a living room rug is 9 ft by 12 ft a strip of floor of equal width is uncovered on all sides of the room if the area od the uncovered floor is 270 ft^2 how wide is the strip

Answers

Step-by-step explanation:

To find the width of the strip of uncovered floor, we need to subtract the area of the covered floor from the total area of the room, and then divide by the width of the strip.

The total area of the room is:

9 ft x 12 ft = 108 ft^2

Let's assume the width of the strip is x.

Then the dimensions of the covered floor are:

Length = 9 - 2x Width = 12 - 2x

The area of the covered floor is:

(9 - 2x) x (12 - 2x) = 108 - 30x + 4x^2

We know that the area of the uncovered floor is 270 ft^2, so we can set up the equation:

108 - 30x + 4x^2 = 270

Simplifying and rearranging:

4x^2 - 30x - 162 = 0

Dividing by 2:

2x^2 - 15x - 81 = 0

Using the quadratic formula:

x = [15 ± sqrt(15^2 + 4(2)(81))]/4

x = [15 ± sqrt(1089)]/4

x = [15 ± 33]/4

x = 12 or x = -3/2

Since the width of the strip cannot be negative, we can discard the negative root, and the width of the strip is:

x = 12/2 = 6 ft

Therefore, the strip of uncovered floor is 6 ft wide.

To approximate binomial probability plx > 8) when n is large, identify the appropriate 0.5 adjusted formula for normal approximation. O plx > 7.5) O plx >= 9) O plx > 9) O plx > 8.5)

Answers

The appropriate 0.5 adjusted formula for normal approximation is option (d) p(x > 8.5)

The appropriate 0.5 adjusted formula for normal approximation to approximate binomial probabilities when n is large is

P(Z > (x + 0.5 - np) / sqrt(np(1-p)))

where Z is the standard normal variable, x is the number of successes, n is the number of trials, and p is the probability of success in each trial.

To approximate binomial probability p(x > 8) when n is large, we need to use the continuity correction and find the appropriate 0.5 adjusted formula for normal approximation. Here, x = 8, n is large, and p is unknown. We first need to find the value of p.

Assuming a binomial distribution, the mean is np and the variance is np(1-p). Since n is large, we can use the following approximation

np = mean = 8, and

np(1-p) = variance = npq

8q = npq

q = 0.875

p = 1 - q = 0.125

Now, using the continuity correction, we adjust the inequality to p(x > 8) = p(x > 8.5 - 0.5)

P(Z > (8.5 - 0.5 - 8∙0.125) / sqrt(8∙0.125∙0.875))

= P(Z > 0.5 / 0.666)

= P(Z > 0.75)

Therefore, the correct option is (d) p(x > 8.5)

a) The expression for the stable fixed point is P* = (1 + sqrt(1 - 4h)) / 2

b) There exists a fixed point for all values of h less than or equal to 1/4.

The fixed points of the model are the values of P at which dP/dt = 0. Therefore, we need to solve the equation

P(1-P) - h = 0

Expanding the left-hand side, we get

P - P^2 - h = 0

Develop a 90% confidence interval for the population mean. b. Develop a 95% confidence interval for the population mean. c. Develop a 99% confidence interval for the population mean. d. What happens to the margin of error and the confidence interval as the confidence level is increased?

Answers

Conversely, as the confidence level decreases, the margin of error becomes smaller, and the confidence interval becomes narrower.

What is confidence interval?

In statistics, a confidence interval is a range of values that is likely to contain the true value of a population parameter (such as a mean or a proportion), based on a sample from that population. The confidence interval is typically expressed as an interval around a sample statistic, such as a mean or a proportion, and is calculated using a specified level of confidence, typically 90%, 95%, or 99%.

Here,

To develop a confidence interval, we need to use the following formula:

Confidence Interval = sample mean ± margin of error

where the margin of error is calculated as:

Margin of Error = z* (sample standard deviation/ √n)

where z* is the critical value from the standard normal distribution table based on the chosen confidence level.

a. For a 90% confidence interval, the critical value (z*) is 1.645. Thus, the margin of error is:

Margin of Error = 1.645 * (4 / √25) = 1.317

So, the 90% confidence interval for the population mean is:

30 ± 1.317, or (28.683, 31.317)

b. For a 95% confidence interval, the critical value (z*) is 1.96. Thus, the margin of error is:

Margin of Error = 1.96 * (4 / √25) = 1.568

So, the 95% confidence interval for the population mean is:

30 ± 1.568, or (28.432, 31.568)

c. For a 99% confidence interval, the critical value (z*) is 2.576. Thus, the margin of error is:

Margin of Error = 2.576 * (4 / √25) = 2.0656

So, the 99% confidence interval for the population mean is:

30 ± 2.0656, or (27.9344, 32.0656)

d. As the confidence level increases, the margin of error also increases, because we need to be more certain that our interval includes the true population mean. This means that the confidence interval becomes wider as the confidence level increases.

Answers

The equation for a linear regression model is represented as: y = B0 + B1x + error.

What is Slope ?

Slope refers to the measure of steepness of a line. It is defined as the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line. It is also called the gradient of the line.

In statistics, a linear regression model is used to describe the relationship between a dependent variable (usually denoted as "y") and one or more independent variables (usually denoted as "x").

The equation for a linear regression model is represented as: y = B0 + B1x + error

where B0 is the y-intercept, B1 is the slope of the line relating y and x, and error is the random error term. The population parameters B0 and B1 are the true values of the y-intercept and slope that would be obtained if the entire population were studied, rather than just a sample.

These parameters are estimated using the sample data, and the resulting estimates are used to construct the regression equation. The estimates of the population parameters are based on the assumption that the sample is representative of the population, and that the errors are normally distributed with constant variance.

Step-by-step explanation:

According to a​ poll, about ​% of adults in a country bet on professional sports. Data indicates that ​% of the adult population in this country is male. Complete parts​ (a) through​ (e).
(b) Assuming that betting is independent of​ gender, compute the probability that an adult from this country selected at random is a male and bets on professional sports.
​P(male and bets on professional ​sports)

0.0568

​(c) Using the result in part​ (b), compute the probability that an adult from this country selected at random is male or bets on professional sports.
​P(male or bets on professional ​sports)

0.5362

​(d) The poll data indicated that ​7.3% of adults in this country are males and bet on professional sports. What does this indicate about the assumption in part​ (b)?
A.
The assumption was incorrect and the events are not independent.

Part 5
​(e) How will the information in part​ (d) affect the probability you computed in part​ (c)? Select the correct choice below and fill in any answer boxes within your choice.
A.
​P(males or bets on professional ​sports) = ?

Answers

a) D. No. A person can be both male and bet on professional sports at the same time

How to solve

b) If the events A and B are independent, P(A&B) = P(A) x P(B)

P(male and also bets on professional sports) = 0.484x0.13 = 0.0629

c) P(male or bets in professional sports) = P(male) + P(bets in professional sports) - P(male and also bets on professional sports)

= 0.484 + 0.13 - 0.0629

= 0.5511

d) A. The assumption was incorrect and the events are not independent

(if the were independent, the percentage would have been 6.29)

e) A. P(male or bets on professional sports = 0.484 + 0.13 - 0.081

= 0.5330

Whenever we construct a confidence interval for the population mean, the margin of error includes the standard error of x bar and theA. sampling biasB. nonresponse biasC. z or t value associated with a 95% confidence levelD. desired level of confidence

Answers

The margin of error in a confidence interval for the population mean includes the standard error of the sample mean and the z or t value associated with a certain level of confidence, usually 95% or 99%. Therefore, the correct answer is (C).

Sampling bias and nonresponse bias are potential sources of error in survey or study design and data collection, but they are not directly related to the construction of a confidence interval.

The desired level of confidence is a key input for determining the z or t value used in the calculation of the margin of error, but it is not included in the margin of error itself. The correct answer is  z or t value associated with a 95% confidence level.

So, the correct option is (C).

What is the length of the distance between the two points of (6,-2)
and (3, 4)?
O √13
O √45
O √65
O √117

Answers

Answer:

[tex]\sqrt {45}[/tex]

Step-by-step explanation:

Distance between two points, (x1, y1) and (x2, y2)  in a 2D cartesian coordinate is given by
[tex]d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex]

here the points are (6, - 2) and (3, 4)

We get

[tex]d = \sqrt {(3 - 6)^2 + (4 - (-2))^2}\\\\d = \sqrt {(-3)^2 + (6)^2}\\\\d = \sqrt {{9} + {36}}\\\\d = \sqrt {45}[/tex]
