A fair number cube with 1, 2, 3, 4, 5 and 6 on its faces is rolled once. The dot on the number line below represents the probability of an event.
Answers
The probability of rolling a specific number is 1/6 or approximately 0.1667.
When rolling a fair number cube with faces numbered 1 through 6, each face has an equal chance of landing face-up. This means the probability of rolling any specific number is 1 out of the total number of faces, which is 6. Therefore, the probability of rolling a specific number is 1/6 or approximately 0.1667.
The dot on the number line represents the probability of an event occurring when rolling the number cube. To determine what this event could be, consider the possible outcomes when rolling the cube and compare their probabilities to the dot's position on the number line.
For example, if the dot is located at 1/6 on the number line, this could represent the probability of rolling a single specific number, such as rolling a 3. If the dot is located at 1/2 or 0.5, it could represent the probability of rolling an even number (2, 4, or 6) since there are three even numbers out of the six total faces, making the probability 3/6 or 1/2.
In summary, the dot on the number line represents the probability of an event occurring when rolling a fair number cube. To identify the event, compare the dot's position on the number line with the probabilities of different outcomes resulting from rolling the cube.

Find the value of x. Polygon angle sums
Answers
Answer:
x = 50
Step-by-step explanation:
In a polygon, the angles add up to 360°:
x + 10 + 2x + 3x + x = 360
7x + 10 = 360
7x = 350
x = 50
Answer:
x = 50
Step-by-step explanation:
There are 4 angles, making it a Quadrilateral. A Quadrilateral has a ∑m∠ of 360°.
Set each angle equal to 360°:
2x + 3x + x + x + 10 = 360
Simplify. Combine like terms:
(2x + 3x + x + x) + 10 = 360
7x + 10 = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents
Roots
Multiplication
Division
Addition
Subtraction
First, subtract 10 from both sides:
7x + 10 (-10) = 360 (-10)
7x = 360 - 10
7x = 350
Next, divide 7 from both sides:
(7x)/7 = (350)/7
x = 350/7
x = 50
50 is your value for x.

What is the equation of the circle with center (0,0) that passes through the point (-6,-6)? need answers right now
O(x+6)² + (y+6)² = 72
0x² + y² = 0
O x² + y² = 72
○(x+6)² + (y+6)² = 0
Answers
The correct equation of the circle with center (0,0) that passes through the point (-6,-6) is:
(x + 6)² + (y + 6)² = 72
Please note that the equation represents the circle with center (0,0) and radius √72.\(\)
Answer:
The equation of a circle with center (0,0) that passes through the point (-6,-6) is:
(x - 0)² + (y - 0)² = r²
where r is the radius of the circle. Since the center of the circle is (0,0), we can use the distance formula to find the radius:
r = √(0 - (-6))² + (0 - (-6))² = √(6² + 6²) = √72
Therefore, the equation of the circle is:
x² + y² = 72
In a flower basket, the ratio of red roses to white roses is 2 to 3. There are a total of 20 roses in the basket. How many red roses are in the basket?
Answers
Explanation:
ratio is 2:3
let’s say red roses are 2x and white roses are 3x.
The total number of roses is 20, then, to find the number of red roses, write:
2x+3x= 20
5x=20
x=4
red roses are 2x
x=4,
hence, put 4 instead of x, and you will get 2*4= 8

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
Answers
Answer:
D.) The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150
Step-by-step explanation:
The given information says that the total amount of lunch bought should equal $150 when both options cost $5:
\(5r+5t=150\)
It also says that the food should feed all 20 employees:
\(r+t=20\)
This is now a system. Solve by substitution.
Solve the second equation for r. Use inverse operations to isolate the variable by subtracting t from both sides:
\(r+t-t=20-t\\\\r=20-t\)
Now insert this value of r into the first equation:
\(5(20-t)+5t=150\)
Simplify the equation. Use the distributive property:
\(5(20)+5(-t)+5t=150\\\\100-5t+5t=150\)
Cancel the terms:
\(100\neq 150\)
100 does not equal 150, so there is no solution to the system.

Use the distributive property to solve this equation:
