find the value of X such that the data set has a mean of 118. 101, 119, 104, 115, 109, x

Answers

Answer:

160

Step-by-step explanation:

101+119+104+115+109+x=548+x

there are 6 terms including x so divide the sum by 6

(548+x)/6=118

multiply both sides by 6

548+x=708

subtract 548

x=160

hope that helps :)

Answer:

160

Step-by-step explanation:

There are 6 numbers in the set

101 + 119 + 104 + 115 + 109 + x = 6(118)

101 + 119 + 104 + 115 + 109 + x = 708

548 + x = 708

x = 160

Write the equation of a line in slope intercept form that passes through (3,-2) and (0,-5)

Answers

Answer:

y=x-5

Step-by-step explanation:

First, you find the slope by -2-(-5)/3-0. This would be 3/3 which is equal to 1. Then you plug in the x with any point you want. I'm going to use (3,-2). The equation should look like -2=3+y. Now we find what is y. Therefore for this equation to be true. Y is equal to -5. Now put it all together. Y=x-5. You can use the other point to check my answer!  Hope that helps!!

Step-by-step explanation:

Raghav, Rajit, Junsu, Mia, and Umema were finished with lunch and began playing with drink straws. Each one was making a line design using either 3 or 4 straws. Since they had just come from math class where they had been studying special angles, Raghav pulled his pencil out of his bookbag and labeled some of the angles and lines. He then challenged himself and the others to find the values of x and y in degrees.

Show how you would find the values of x and y for Raghav’s straw figure shown below using a system of linear equations. (You may use a decimal to the tenths place for your answers for the angle measures.)

Answers

Answer:

x = [tex]25.8^{o}[/tex] and y = [tex]51.4^{o}[/tex]

Step-by-step explanation:

Known that he sum of angles on a straight line is [tex]180^{o}[/tex]. From the diagram;

2y + x + y = [tex]180^{o}[/tex]

x + 3y = [tex]180^{o}[/tex] ................ 1

Also,

2x + x + 2y = [tex]180^{o}[/tex]

3x + 2y = [tex]180^{o}[/tex] .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = [tex]180^{o}[/tex] ............. 4

7y = 360

y = [tex]\frac{360}{7}[/tex]

y = [tex]51.4^{o}[/tex]

substitute the value of y in equation 1,

x + 3y = [tex]180^{o}[/tex]

x + 3(51.4) = [tex]180^{o}[/tex]

x + 154.2 = [tex]180^{o}[/tex]

x = [tex]180^{o}[/tex] - 154.2

x = [tex]25.8^{o}[/tex]

Thus, x = [tex]25.8^{o}[/tex] and y = [tex]51.4^{o}[/tex]

Match the sides based on their relationship to A

It can be calculated by finding the difference between the two angles. Half of this difference will be the angle that is required.

Therefore

Some of these changes are caused by natural processes, but many believe these changes in climate are a direct result of human activity. Luckily, we have the power to make small changes to reduce the impact on our planet. Every day, we throw away garbage that releases harmful toxins into the air, land, and water. One way you can prevent harmful pollutants is by composting. Composting is the process by which organic materials, such as fruit, vegetables, eggshells, tea, and many other foods, are broken down, recycled, and used as a fertilizer. As a fertilizer, compost provides rich nutrients to the soil. It is very beneficial to your gardens, as it nourishes your plants and flowers and helps them bloom more frequently. It is very easy to start composting. All you need is a wooden or plastic compost bin and the organic matter to put in it! Composting helps the environment because it reduces the amount of waste in landfills, reduces pollution, and prevents soil erosion. Take a stand, and help make the planet we live on a healthier place.What is the author's point?Group of answer choices1.Composting is not an important part of creating a sustainable community.2.Humans cannot change the amount of waste that ends up in landfills.3.It is very easy to begin the process of composting at home.4.The process of composting can improve the environment.
