On her way to work, Mrs. Larsen gets a green light at a certain traffic light only 30% of the time. She wants to find the probab

ility that she will get a green light at this traffic light all five mornings that she travels to work next week. Use the following randomly generated list of 200 five-digit numbers to answer the questions and find the probability.
Select the digits you will use to represent a favorable outcome.
How many favorable outcomes are on this list? What are they?
Given this simulation, what is the probability that Mrs. Larsen will get a green light at this traffic light all five mornings next week?

First, use the random number table to generate the possible probabilities but only account the first four digits in order to get a value that is a percentage
35.85%
28.97%
90.12%
5.07%
20.43%
The average is
36.09%
There is a 36.09% probability that the light will be green when reaches the traffic light

How to find the surface area and volume of a square
3241004551 [841]

Given:

The shape is square.

To find:

The surface area and volume of a square.

Explanation:

The length of each side of the square is "a" units.

The formula for the surface area of the square is,

\begin{gathered} Surface\text{ area = 6}\times Area\text{ of the square} \\ S.A=6a^2\text{ square units} \end{gathered}

The formula for the volume of the square is,

\begin{gathered} Volume,\text{ V= Length }\times breadth\times Height \\ =a\times a\times a\text{ cubic units} \\ V=a^3\text{ }cubic\text{ }units \end{gathered}

Using these formulas, we can find the surface area and the volume of the square that has side length "a" units.

For example:

Let the side length of 3cm for a square.

So, the dimensions are 3cm by 3cm by 3cm.

That is,

The Length is 3cm.

The breadth is 3cm.

The height is 3cm.

So,

a=3cm

The surface area of the square is,

\begin{gathered} S.A=6a^2 \\ =6\left(3\right)^2 \\ =6\times9 \\ =54cm^2 \end{gathered}

Therefore, the surface area of the square is 54 square cm.

The volume of the square is,

\begin{gathered} V=a^3 \\ =3^3 \\ V=27cm^3 \end{gathered}

Therefore, the volume of the square is 27 cubic cm.

Y= 3x + 1
Alika [10]

Answer:

y= -11

Step-by-step explanation:

After rearranging equation 2, we get x= y+3/2

Sub it into equation 1

y= 3(y+3/2) + 1

y= 3y+9/2 + 1

y= 3y + 11 / 2

2y = 3y + 11

-y = 11

y = -11

The systems shown have the same solution set.<br><br> A) True<br> B) False
Ksju [112]

Answer:

True

Step-by-step explanation:

True.

The solution to a system of equations is the point where two equations intercept. In both cases, we can see that the interception of the two systems shown occurs at (0, 1). So the statement is correct.

Someone please help me solve this problem! If you’re smart you can solve it!
adell [148]

let's notate it with letters to I can notate it in this problem

the plus is P

the circle is C

the square is S

the smiley face is F (for face)

the triangle is T


in all, we see that:

circle can't be next to the smiley face or the triangle or the square so it must be at the end next to to the plus sign but we don't know if it is at the right end or the left (____P C or C P____)


plus is not next to smiley face or triangle, so it must be next to the square (___S P C or C P S___)


triangle is to the right of the square, so we have to choose the guess that has an empty space to the right of the square, so it has to be C P S T __


then the last shape is the smiley face which goes in the last space

so the order is C P S T F or circle, plus, square, triangle smiley face
