∠DFG and ∠JKL are complementary angles. m∠DFG = x + 5, and m∠JKL = x − 1. Find the measure of each angle.

Answers

∠DFG and ∠JKL are complementary angles

Measure of each angle

[tex]m<DFG=48\\m<JKL= 42[/tex]

Given :

∠DFG and ∠JKL are complementary angles. m∠DFG = x + 5,

and m∠JKL = x − 1

When two angles are complementary then the sum of angles is 90 degrees

∠DFG and ∠JKL are complementary angles.

So, [tex]m<DFG+m<JKL =90[/tex]

Now replace the expressions and solve for x

[tex]x+5+x-1=90\\2x+4=90\\2x=90-4\\2x=86\\x=43[/tex]

Now replace x with 43 and find out each angle

[tex]m<DFG= x+5\\m<DFG= 43+5=48\\\\m<DFG=48\\m<JKL=x-1=43-1=42[/tex]

a line that intersects the points (-23,-17) and (-13,-7), find the slope, now fill in the missing inputs to the slope-intercept formula -17=1(?)+b or (?)=(-13)+b

Answers

The slope of the line can be calculated using the following formula:
slope = (y2-y1) / (x2-x1)

The given points are (-23,-17) and (-13,-7), therefore:
y2 = -7
y1 = -17
x2 = -13
x1 = -23

Substitute with these values to get the slope as follows:
slope (m) = (-7--17) / (-13--23) = 1

The formula of the slope-intercept is:
y = mx+b where m is the slope and b is the intercept.
Using the point (-23,-17), the formula would be:
-17 = 1(-23) + b
Using the point (-13,-7), the formula would be:
-7 = 1(-13) + b

What is the margin of error for a sample statistic for a population with a standard deviation of 11.3?

Answers

The margin of error for a sample statistic requires the population standard deviation, the desired confidence level, and the sample size. It is found by multiplying the z-score for the confidence level with the standard error, which is the population standard deviation divided by the square root of the sample size. For a 95% confidence interval, the error bound is factored into the sample mean to estimate the population mean.

The margin of error for a sample statistic depends on the level of confidence desired and the sample size. Using the population standard deviation, we can calculate the margin of error by finding the z-score associated with the desired confidence level and multiplying it by the standard error. The standard error is calculated as the population standard deviation (11.3) divided by the square root of the sample size (n).

Based on the example given referencing an error bound for the mean (3.2), a 95% confidence interval could be constructed by adding and subtracting the error bound from the sample mean (15). Therefore, the 95% confidence interval estimate for the population mean would be (11.8, 18.2).

When a sample standard deviation is provided instead of a population standard deviation, and if the sample size is small, the Student's t-distribution should be used instead of the normal distribution.

For a 95% confidence interval, we generally use 1.96 as the z-score for a normal distribution, but this value could change depending on specific confidence levels or other distributions like the t-distribution.

Two numbers total 53 and have a difference of 25. Find the two numbers.

Answers

Two numbers (x + y) equal (=) 53
and
have a difference (x - y) of (=) 25.

So, x + y = 53 and x - y = 25.

Solve one equation for a variable. We'll solve for x in the first equation.

x + y = 53 Subtract y from both sides
x = 53 - y

Substitute x for (53 - y) in the second equation.

x - y = 25 Substitute (53 - y) in the x spot
53 - y - y = 25 Combine like terms (-y and -y)
53 - 2y = 25 Subtract 53 from both sides
-2y = -28 Divide both sides by -2
y = 14

Now, find x by plugging this y-value (14) into the first equation.

x + y = 53 Substitute y for 14
x + 14 = 53 Subtract 14 from 53
x = 39

Check both of your answers by plugging them into the original equations.

x + y = 53 Plug in your numbers (39 and 14)
39 + 14 = 53 Add
53 = 53

x - y = 25 Plug in your numbers (39 and 14)
39 - 14 = 25 Subtract
25 = 25

So, your answers are x = 39 and y = 14 .

Instead space out your studying, review class materials at least several times a week, focusing on one topic at a time.
Have all of your study material in front of you: lecture notes, course textbooks, study guides and any other relevant material.
Find a comfortable and quiet place to study with good lighting and little distractions
(try avoiding your own bed, it is very tempting to just lie down and take a nap).
Start out by studying the most important information.
Learn the general concepts first, don't worry about learning the details until you have learned the main ideas.
Take notes and write down a summary of the important ideas as you read through your study material.
Take short breaks frequently. Your memory retains the information that you study at the beginning and the end better than what you study in the middle.
Space out your studying, you'll learn more by studying a little every day instead of waiting to cram at the last minute. By studying every day, the material will stay in your long-term memory but if you try to study at the last moment, the material will only reside in your short-term memory that you'll easily forget.
Make sure that you understand the material well, don't just read through the material and try to memorize everything.
If you choose to study in a group, only study with others who are serious about the test.
Test yourself or have someone test you on the material to find out what your weak and strong areas are. You can use the review questions at the end of each chapter or practice tests the teacher may give out as well as other materials.
Listening to relaxing music such as classical or jazz on a low volume can relieve some of the boredom of studying.
Don't study later than the time you usually go to sleep, you may fall asleep or be tempted to go to sleep, instead try studying in the afternoon or early evening. If you are a morning person try studying in the morning.

A sector of area 2pi/3 square inches is formed by a central angle of 45 degrees. What is the radius of the circle?

Answers

Final answer:

Using the formula for the area of a sector, we substitute provided values to find the radius of the circle. Solving the equation, we find the radius to be √6 inches.

Explanation:

The subject of the question is related to geometry and involves understanding the relationship between the area of a sector and the radius of the circle it is part of. The sector is formed by a central angle of 45 degrees and its area is given as 2π/3 square inches.

In order to find the radius of the circle, we can use the formula for the area of a sector, which is (θ/2π) * πr2, where θ is the central angle, π is a mathematical constant, and r is the radius of the circle.

Considering 360 degrees as 2π radians, the angle is 45 * (2π/360) = π/4 radians. Hence substituting the values in the area equation we get; 2π/3 = (π/4)/2π * πr2. If we solve this equation for 'r', we get r = √6 inches as the radius of the circle.

A 20-foot cable hangs from the top of a building that is 50 feet high. if the cable weighs 2 pounds per foot, how much work is done in lifting up the entire cable to the top of the building?

Answers

20*2=40
40*50=2000
2000/60=33.33
about 33 hours by lifting by hand

Final answer:

To find the work done in lifting the entire cable to the top of the building, multiply the weight of the cable by the height of the building.

Explanation:

To calculate the work done in lifting the entire cable to the top of the building, we need to find the weight of the cable. The weight of the cable can be found by multiplying the length of the cable (20 feet) by its weight per foot (2 pounds per foot). Therefore, the weight of the cable is 20 feet × 2 pounds per foot = 40 pounds.

The work done in lifting the cable to the top of the building is equal to the product of the weight of the cable and the height of the building. So, the work done is 40 pounds × 50 feet = 2000 foot-pounds.
