The area of a circle is 81 ft 2 . What is the π circumference? Leave in terms of Pi.
Answers
Answer:
10.2π
Step-by-step explanation:
Given data
Area of circle= 81 ft^2
Also, the expression for the area of a circle is
A=πr^2
substitute
81=3.142*r^2
r^2= 81/3.142
r^2= 25.77
square both sides
r= √25.77
r= 5.1
Also, the expression for the circumference is
C= 2πr
substitute
C= 2*π*5.1
C= 10.2π
Hence the circumference is 10.2π
You want to wrap a gift shaped like the regular triangular prism shown. How many square inches of wrapping paper do you need to completely cover the prism?
Answers
The resulting expression represents the total surface area of the triangular prism. To determine the number of square inches of wrapping paper needed, you would measure the values of 'b', 'h', and 'H' in inches and plug them into the formula.
To determine the amount of wrapping paper needed to cover a regular triangular prism, we need to find the total surface area of the prism.
A regular triangular prism has two congruent triangular bases and three rectangular faces. The formula for the surface area of a regular triangular prism is:
Surface Area = 2(base area) + (lateral area)
To calculate the base area, we need to know the length of the base and the height of the triangle. Let's assume the length of the base is 'b' and the height of the triangle is 'h'. The base area can be calculated using the formula:
Base Area = (1/2) * b * h
Next, we need to calculate the lateral area. The lateral area is the sum of the areas of all three rectangular faces. Each rectangular face has a width equal to the base length 'b' and a height equal to the height of the prism 'H'. Therefore, the lateral area can be calculated as:
Lateral Area = 3 * b * H
Finally, we can substitute the values of the base area and lateral area into the surface area formula:
Surface Area = 2 * Base Area + Lateral Area
= 2 * [(1/2) * b * h] + 3 * b * H
= b * h + 3 * b * H

the standard deviation of a dataset is a number a series of numbers an interval a verbal description
Answers
The standard deviation of a dataset is a number.
The standard deviation is a statistical measure that quantifies the amount of dispersion or variability within a dataset. It provides a numerical representation of how spread out the data points are from the mean (average) value. In other words, it measures the average distance between each data point and the mean.
To calculate the standard deviation, the following steps are typically followed:
Calculate the mean of the dataset by summing all the values and dividing by the number of observations.
Calculate the difference between each data point and the mean.
Square each difference.
Find the average of the squared differences.
Take the square root of the average to obtain the standard deviation.
The standard deviation is expressed in the same unit as the original dataset, providing a measure of the typical or expected deviation from the mean value. A larger standard deviation indicates a greater degree of variability, while a smaller standard deviation indicates less variability and a more tightly clustered dataset.

3. (-2, 0) and (0, 5)
4. a = 2, b = -7
5, m = 2, (3, -1)
Answers
Answer:
1) The slope-intercept and standard forms are \(y = -5\cdot x + 1\) and \(5\cdot x +y = 1\), respectively.
2) The slope-intercept form of the line is \(y = \frac{5}{2}\cdot x -\frac{9}{2}\). The standard form of the line is \(-5\cdot x +2\cdot y = -9\).
3) The slope-intercept form of the line is \(y = \frac{5}{2}\cdot x + 5\). The standard form of the line is \(-5\cdot x +2\cdot y = 10\).
4) The slope-intercept and standard forms of the family of lines are \(y = \frac{2}{7}\cdot x -\frac{c}{7}\) and \(2\cdot x -7\cdot y = c\), \(\forall \,c \in \mathbb{R}\), respectively.
5) The slope-intercept form of the line is \(y = 2\cdot x-7\). The standard form of the line is \(-2\cdot x +y = -7\).
Step-by-step explanation:
From Analytical Geometry we know that the slope-intercept form of the line is represented by:
\(y = m\cdot x + b\) (1)
Where:
\(x\) - Independent variable, dimensionless.
\(m\) - Slope, dimensionless.
\(b\) - y-Intercept, dimensionless.
\(y\) - Dependent variable, dimensionless.
In addition, the standard form of the line is represented by the following model:
\(a\cdot x + b \cdot y = c\) (2)
Where \(a\), \(b\) are constant coefficients, dimensionless.
Now we process to resolve each problem:
1) If we know that \(m = -5\) and \(b = 1\), then we know that the slope-intercept form of the line is:
\(y = -5\cdot x + 1\) (3)
And the standard form is found after some algebraic handling:
\(5\cdot x +y = 1\) (4)
The slope-intercept and standard forms are \(y = -5\cdot x + 1\) and \(5\cdot x +y = 1\), respectively.
2) From Geometry we know that a line can be formed by two distinct points on a plane. If we know that \((x_{1},y_{1})=(1,-2)\) and \((x_{2},y_{2}) = (3,3)\), then we construct the following system of linear equations:
\(m+b= -2\) (5)
\(3\cdot m +b = 3\) (6)
The solution of the system is:
\(m = \frac{5}{2}\), \(b = -\frac{9}{2}\)
The slope-intercept form of the line is \(y = \frac{5}{2}\cdot x -\frac{9}{2}\).
And the standard form is found after some algebraic handling:
\(-\frac{5}{2}\cdot x +y = -\frac{9}{2}\)
\(-5\cdot x +2\cdot y = -9\) (7)
The standard form of the line is \(-5\cdot x +2\cdot y = -9\).
3) From Geometry we know that a line can be formed by two distinct points on a plane. If we know that \((x_{1},y_{1})=(-2,0)\) and \((x_{2},y_{2}) = (0,5)\), then we construct the following system of linear equations:
\(-2\cdot m +b = 0\) (8)
\(b = 5\) (9)
The solution of the system is:
\(m =\frac{5}{2}\), \(b = 5\)
The slope-intercept form of the line is \(y = \frac{5}{2}\cdot x + 5\).
And the standard form is found after some algebraic handling:
\(-\frac{5}{2}\cdot x+y =5\)
\(-5\cdot x +2\cdot y = 10\) (10)
The standard form of the line is \(-5\cdot x +2\cdot y = 10\).
4) If we know that \(a = 2\) and \(b = -7\), then the standard form of the family of lines is:
\(2\cdot x -7\cdot y = c\), \(\forall \,c \in \mathbb{R}\)
And the standard form is found after some algebraic handling:
\(-7\cdot y = -2\cdot x +c\)
\(y = \frac{2}{7}\cdot x -\frac{c}{7}\), \(\forall \,c\in\mathbb{R}\) (11)
The slope-intercept and standard forms of the family of lines are \(y = \frac{2}{7}\cdot x -\frac{c}{7}\) and \(2\cdot x -7\cdot y = c\), \(\forall \,c \in \mathbb{R}\), respectively.
5) If we know that \((x,y) = (3,-1)\) and \(m = 2\), then the y-intercept of the line is:
\(3\cdot 2 + b = -1\)
\(b = -7\)
Then, the slope-intercept form of the line is \(y = 2\cdot x-7\).
And the standard form is found after some algebraic handling:
\(-2\cdot x +y = -7\) (12)
The standard form of the line is \(-2\cdot x +y = -7\).
The weights of ice cream cartons are normally distributed with a mean weight of 12 ounces and a standard deviation of 0.5 ounce (a) What is the probability that a randomly selected carton has a weight greater than 12.31 ounces? (b) A sample of 16 cartons is randomly selected. What is the probability that their mean weight is greater than 12.31 ounces? (a) The probability is (Round to four decimal places as needed.)
Answers
The probability that a randomly selected carton has a weight greater than 12.31 ounces is approximately 0.2676.
To calculate the probability that a randomly selected carton has a weight greater than 12.31 ounces, we can use the z-score and the standard normal distribution.
(a) Probability for a single carton:
Step 1: Calculate the z-score using the formula: z = (x - μ) / σ
Where:
x = 12.31 (the given weight)
μ = 12 (mean weight)
σ = 0.5 (standard deviation)
z = (12.31 - 12) / 0.5 = 0.62
Step 2: Find the probability associated with the z-score using a standard normal distribution table or a calculator. The probability of a weight greater than 12.31 ounces is equivalent to finding the area to the right of the z-score of 0.62.
Using a standard normal distribution table or calculator, the probability is approximately 0.2676.
Therefore, the probability that a randomly selected carton has a weight greater than 12.31 ounces is approximately 0.2676.
Note: Make sure to round the result to four decimal places as requested.

Density is the amount of things (people, animals, plants, or items) in a given area. To compute density, divide the number of items by the area measured. A country's population density is the number of inhabitants divided by its area in square kilometers or miles.
The amount of a quantity (typically mass) per unit of area is known as surface density. Density=Quantity/Area.
The quantity of data that can be stored on a given unit of physical space on storage medium is measured as areal density.

Answers
The percentage of the students who wore a silly hat is 64 %.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that Last Tuesday was a silly hat day at Aaron's school. 64 students wore a silly hats and 36 students did not.
We have to determine the percentage of the students who wore a silly hat
The total number of students = 64 students wore silly hats and 36 students did not.
The total number of students = 64 + 36 = 100
We have to determine the percentage of the students who wore a silly hat
The percentage of the students wore a silly hat = (64/ 100) × 100
The percentage of the students wore a silly hat = 0.64 × 100
The percentage of the students wore a silly hat = 64 %
Thus, the percentage of students who wore silly hats is 64 %.

Answers
To find the estimated project completion time for the given project activities, we need to first calculate the earliest start and earliest finish times and then the latest start and latest finish times.
Using the activity times given, we can calculate the earliest start and earliest finish times for each activity as follows: Activity A: Earliest start time = 0
Earliest finish time = 1
Activity B: Earliest start time = 2
Earliest finish time = 5
Activity C: Earliest start time = 5
Earliest finish time = 11
Activity D: Earliest start time = 11
Earliest finish time = 17
Activity E: Earliest start time = 5
Earliest finish time = 8 Activity F:
Earliest start time = 8
Earliest finish time = 17
Now we can calculate the latest start and latest finish times for each activity using the backward pass.
Latest finish time = 5
Latest start time = 2
Activity A: Latest finish time = 1
Latest start time = 0
Now we can calculate the slack time for each activity as follows:Activity A:
Slack time = 0
Activity B: Slack time = 0
Activity C: Slack time = 0
Activity D: Slack time = 0
Activity E: Slack time = 3
Activity F: Slack time = 0
The critical path for this project is A -> C -> D, since these activities have zero slack time. Therefore, the estimated project completion time is 17 units of time.

Upper Quartile (Q3) = 3/4(N+1)
Lower Quartile (Q1) = (N+1) * 1/3
Middle Quartile (Q2) = (N+1) * 2/3
Interquartile Range = Q3 -Q1,
1.74, 0.24, 1.56, 2.79, 0.89, 1.16, 0.20, and 1.84 are available.

The data set has 8 values.
hence, n = 8; third quartile: 3/4 (n+1)th term
Q3 =3/4 of a term (9) term
Q3 =27/4 th term
Q3 = 1.74 + 1.84 / 2 (average of the sixth and seventh terms)

what is the difference between 17/100 x 20 and 17/20 x 100 in percentage
Answers
96% percentage is the difference between 17/100 x 20 and 17/20 x 100
The difference between (17/100) x 20 and (17/20) x 100 can be calculated by finding the absolute difference between the two values and expressing it as a percentage of the larger value.
First, let's calculate each expression:
(17/100) x 20 = 0.17 x 20 = 3.4
(17/20) x 100 = 0.85 x 100 = 85
The difference between these two values is |85 - 3.4| = 81.6.
To express this difference as a percentage of the larger value, we divide 81.6 by the larger value (85 in this case) and multiply by 100:
(81.6 / 85) x 100 = 96%
Therefore, the difference between (17/100) x 20 and (17/20) x 100 is approximately 96% of the larger value.
