Write the piecewise function for the graph.

Answers

Answer:

In the picture

Step-by-step explanation:

First, find a function for each line.

-2x - 2 fits the green line because for every x value, y is -2(x) - 2.

2x + 1 fits the red line because for every x value y is 2(x) + 1.

You also need to include "if." -2x -2 if x < 0.

For the red line, the dot is closed so if x ≥ 0.

Step-by-step explanation:

The probability that the first student walks to school will be: = 7/30.

The probability of selecting the second student that walks to school will be: = 6/29.

median of 22, 16, 14, 26, 32, 30​

Answers

Answer:

15

Step-by-step explanation:

cancel out from the sides till you have 1 number in the middle but in this case we have 2 numbers.

in a case like that you add both numbers and divide by 2 to get your answer

so 16+14÷2= 15

Median is the middle

Since there is an equal amount of numbers,6, you would need to take the average of the two numbers in the middle.

REMEMBER: always put it in ascending order first (0-10)

14, 16, 22, 26, 30, 32

Middle numbers are: 22 and 26

Take average: (22+26)/2 = 24

Therefore the median of this sequence is 24.

A survey was conducted at a town hall meeting to determine if a new park should be built. Out of the 3,462 people surveyed, 1,468 people voted that the town should not build a new park.

Assuming the survey was random, what percentage of people in the town would likely vote in favor of the new park?

Enter your answer to the nearest percent in the box.

%

Answers

Answer: 58%

Step-by-step explanation:

Answer:

58%

Step-by-step explanation:

If 1468 weren't in favor of the new park, then 3462-1468=1996 people were in favor of the new park. This means the percentage of those who are in favor of the park is 1996/3462=0.5765=57.65%=58%

A fan oscillates 250* and can be felt from a distance of 4 feet away . To the nearest tenth what area of the room can feel the wind from the fan? Use 3.14 for pi .

Answers

Answer:

[tex]A=256.67ft^2[/tex]

Step-by-step explanation:

From the question we are told that:

Fan oscillates [tex]\theta=250[/tex]

Distance [tex]d=>Raduis\ r=4 feet[/tex]

Since

 [tex]250\textdegree =180\textdegree +70\textdegree[/tex]

Generally the equation for the area A is mathematically given by

 [tex]Area=Area\ of\ semi\ circle\ + area\ of\ 70\textdegree sector[/tex]

 [tex]A=A_{sm}+A_{70\textdegree}[/tex]

Where

 [tex]A_{sm}=\frac{1}{2} \pi r^2[/tex]

 [tex]A_{sm}=\frac{1}{2} 3.14 4^2[/tex]

 [tex]A_{sm}=25.12ft^2[/tex]

 [tex]A_{70\textdegree}=\frac{1}{2}r^2 \frac{70\textdegree}{360\textdegree}[/tex]

 [tex]A_{70\textdegree}=\frac{1}{2}*4^2* \frac{70\textdegree}{360\textdegree}[/tex]

 [tex]A_{70\textdegree}=1.55ft^2[/tex]

Therefore the area A is given as

 [tex]A=A_{sm}+A_{70\textdegree}[/tex]

 [tex]A=25.12ft^2+1.55ft^2[/tex]

 [tex]A=256.67ft^2[/tex]

Grace’s garden is shown below. She is going to buy bags of soil that cover 75 square feet each. How many bags of soil will she need for her entire garden? Use 3.14 for pi.


A. 4 bags

B. 5 bags

C. 6 bags

D. 7 bags

Answers

Answer: C. 6 bags

Step-by-step explanation:

To solve this, you need to calculate the area of every shape in the garden and then sum them up.

Semi circle:

Area of semi-circle = (π * radius²) / 2

Radius = Diameter/ 2 = 18/2 = 9 feet

Area = (3.14 * 9²) / 2

= 127.17 ft²

Rectangle:

= Length * Width

= 18 * 8

= 144 ft²

Triangle

= 1/2 * base * height

= 1/2 * 18 * 18

= 162 ft²

Added up:

= 127.17 + 144 + 162

= 427.17 ft²

If each bag covers 75 ft² each, the number of bags needed is:

= Area to cover / Coverage per bag

= 427.17 / 75

= 5.7

= 6 bags
