Find the area of the backyard

A=20(14)=280\ yd^{2}

step 2

Find the area of the flower garden

A=5(9)=45\ yd^{2}

step 3

Find the difference

280\ yd^{2}-45\ yd^{2}=235\ yd^{2}

Use the bar graph. Astronauts installed 15 new tiles on the outside of the space station they spent 390 minutes on the task. eac
11111nata11111 [884]

Answer:

11. It will take about 26 minutes to install a singular tile.

12. It will take about 10 more minutes to install a light than it does to install a cable.

Step-by-step explanation:

11. Since installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time, you can divide the total amount of time by the number of tiles.

390/15= 26 minutes

It will take about 26 minutes to install a single tile.

12. By looking at the chart it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.

22-12= 10 minutes

It takes about 10 minutes longer to install a light than it does a cable.

A random sample of n 5 4 individuals is selected from a population with m 5 35, and a treatment is administered to each individu
Firdavs [7]

Answer:

5.1

Step-by-step explanation:

Given that:

sample size n = 4

the mean of the original population  μ is = 35

and the mean for the sample after treatment M is = 40.1

standard deviation of the sample SS = 48

The difference between the mean for the treated sample and the mean for the original population is therefore calculated as: M -  μ

= 40.1 - 35

= 5.1

The standard error of M is = \dfrac{standard \ deviation \ of \ the \ sample}{\sqrt{sample \ size} }

The standard error of M is = \dfrac{SS}{\sqrt{n} }

The standard error of M is = \dfrac{48}{\sqrt{4} }

The standard error of M is = \dfrac{48}{2 }

The standard error of M is = 24

If a polygon has a vertex at (161, -329) and it is translated 168 units to the right, what are the coordinates of that vertex's
bearhunter [10]
Vertex of the polygon is (161, -329)

The new vertex is shifted 168 units to the right. A horizontal shift can be achieved be adding or subtracting the number from the x-coordinate. A change in the y coordinate brings the vertical shift. So in this case the x-component will change only and y component will be the same.

A shift towards right means, the value of x component is increase as x gets larger as we move towards right on the graph. So moving 168 units to the right, we will get the following vertex (329 , -329)

Thus, the new vertex of the polygon will be at the point (329, -329)
