There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
What is the theoretical probability of randomly drawing a red marble?
25%
20%
62.5%
41.7%
Answer: Second Option
20%
Step-by-step explanation:
We have 5 red marbles, 8 blue marbles and 12 green marbles in a bag.
In total there are 5 + 8 + 12 = 25 marbles
This means that the experiment "get a marble out of the bag" has 25 possibilities.
Then, the chances of getting a red marble are 5, because there are 5 red marbles.
Finally the probability of drawing a red marble is:
[tex]P_{red} = \frac{5}{25}\\\\P_{red} = \frac{1}{5}\\\\P_{red} = 0.20[/tex]
[tex]P_{red} =20\%[/tex]

which answer best describes the shape of this distribution
A. skewed right
B. skewed left
C. uniform
D. bell-shaped
Answer:
B.. skewed left
Step-by-step explanation:
Answer:
Option B. skewed left.
Step-by-step explanation:
In the figure attached maximum frequency of the data is at the 45. Distribution on the right side of the maximum frequency is upto 48 and in the left it is upto 36.
As we can see point 36 is more distant from peak point 45 as compared to point 48.
Therefore, distribution of the data is more in the left than in the right.
Therefore, the shape of this distribution is skewed left.
Option B. skewed left is the correct answer.
Which coordinate pair identifies a point in the third quadrant of the coordinate plane?
A) (0, 6)
B) (−6, 2)
C) (2, −6)
D) (−6, −2)
Answer:
D, (-6,-2)
Step-by-step explanation:
the first quadrant of a coordinate plane has the x coordinate being a negative number, and the y coordinate being a positive number
the second quadrant of a coordinate plane has the x and y coordinates being a positive number
the third quadrant of a coordinate plane has the x and y coordinates being a negative number
the fourth quadrant of a coordinate plane has the x coordinate being a positive number, and the y coordinate being a negative number
i have attached a graph showing the quadrants for a visual point of view
The coordinate pair that identifies a point in the third quadrant of the coordinate plane, where both x and y coordinates are negative, is (-6,-2)
Explanation:The question is asking about identifying which pair of coordinates falls into the third quadrant of the coordinate plane in mathematics. The third quadrant in a coordinate plane is the bottom-left quadrant, where both the x and y coordinates are negative.
Looking at the options: A) (0,6), B) (-6,2), C) (2,-6), and D) (-6,-2); we can clearly see that option D) (-6,-2) is the point in the third quadrant, as both coordinates are negative. The pair (-6,-2) meets this description, with -6 on the x-axis and -2 on the y-axis. So, the correct answer is option D).

the shorter side lengths both equal 5 units so that would be 5+5=10
the longer side lengths both equal 9 units so that would be 9+9=18
18+10=28 units
Answer:
The correct answer would be 28 units.
Step-by-step explanation:
the length of the recktangle is 9. There are two sided with 9 so you would add 9+9. The height of the rectangle is 5 and there are two heights. You add 5+5 then you add 18 witch is the sum of 9+9 and you get 28.

The perimeter of the trapezoid shown is 6x+2 units. Find the length of the missing side
The missing length of the missing side is x+1.
To find the perimeter of this object, we need to know hat perimeter truly means.
Perimeter-The sum of all the sides.
The sides from the trapezoid are 3x+1, x , and x.
We combine like terms, so 3x + x + x = 5x
1 is the only number.
We are left off with 5x+1. Our objective is to get 6x+2.
How do we get there? We add 1x or x (1x and x) are the same thing, and we add one.
5x+1 + 1x + 1 = 6x+2;
Therefore the renaming length of the missing side is 1x+1.

Answer:
x + 1
Step-by-step explanation:
Is that a lone x on the left hand side? I will assume so.
Let y be the value of the side marked with a ?.
x + 3x + 1 + x + y = 6x + 2 collect the like terms on the left.
5x + 1 + y= 6x + 2 Subtract 1 from both sides.
5x + 1-1 +y = 6x + 2-1 Combine
5x + y = 6x + 1 Subtract 5x from both sides.
5x-5x + y = 6x -5x +1 Combine
y =x + 1
The missing side is x +1
Find the slope of the line that passes through the points (-6,-8) and (-6,12)
Answer:
The slope is 0. However, it is a horizontal line where x=-6.
Step-by-step explanation:
Use the equation m= y2-y1/x2-x1 to get 12--8/-6--6. Two negatives means a positive, so you get 20/0. This means there is no slope, because you cannot divide by 0. However, you notice that both x-values are -6, so you can safely assume that there is a horizontal line where x=-6.
The slope is undefined and the line is vertical and parallel to the y-axis.
Given points (-6, -8) and (-6, 12)
First, the slope of line is
Slope= (change in y/ change in x
= (12 - (-8)) / (-6 - (-6))
= (12 +8) / (-6 +6)
= 20 /0
= ∞
Since we have a division by zero in the denominator, the slope is undefined.
This indicates that the line is vertical and parallel to the y-axis.
Thus, the slope is undefined.

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation.
Answer:
[tex]f(x) = 6x -12[/tex]
Step-by-step explanation:
We must write the function of the line in the form [tex]f (x) = mx + b[/tex]
First calculate the slope m
[tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]y_2 = 18\\y_1 =6\\x_2=5\\x_1=3[/tex]
[tex]m= \frac{18-6}{5-3} = 6[/tex]
Then
[tex]f(x) = 6x +b[/tex]
To have b replaced a point in the function
[tex]f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12[/tex]
Finally the function is
[tex]f(x) = 6x -12[/tex]
ANSWER
[tex]f(x) = 6x - 12[/tex]
EXPLANATION
The given line passes through the points (3, 6) and (5, 18).
The slope of this line given by:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
We plug in the points to get,
[tex]m = \frac{18 - 6}{5 - 3} = \frac{12}{2} = 6[/tex]
The equation is given by
[tex]y-y_1=m(x-x_1)[/tex]
We plug in the point and the slope to get,
[tex]y - 6 = 6(x - 3)[/tex]
[tex]y - 6 = 6x - 18[/tex]
[tex] y = 6x - 18 + 6[/tex]
[tex]y = 6x - 12[/tex]
Using function notation, we have
[tex]f(x) = 6x - 12[/tex]

Select the expression below that is equal to 6(9 - m).
Answer:
The answer would be m= -9
Step-by-step explanation:
6(9-m)
You will multiply the 6 with the 9 and -m inside of the parenthesis
54-6m
Divide by -6 on both sides and you will get m= -9
I hope this helps you with this question and have a nice weekend
The equivalent expression to 6(9 - m) is 54 - 6m, determined by applying the distributive property of multiplication over addition and subtraction.
The expression given is 6(9 - m). To identify an expression equal to this, we should look for expressions that maintain the same relationship between the numbers and the variable m. When we distribute the 6 across the parentheses, we multiply 6 by 9, and 6 by -m, resulting in 54 - 6m.
Distributing a number across a subtraction in a parenthesis follows the distributive property of multiplication over addition and subtraction, which allows us to multiply each term inside the parentheses by the number outside.

Answer:
80π feet/ second.
Step-by-step explanation:
Angular velocity of a point = 10π radians per second
Radius of the circle is 8 feet.
We know the formula of angular velocity is
Angular velocity = [tex]\frac{speed}{radius}[/tex]
10π = [tex]\frac{speed}{8}[/tex]
Speed = 80π feet/ second.
