Answer:
1/14
Step-by-step explanation:
a four out of possible 6 rolls = 1/6
6 red out of 14 balls 6/14
1/6 * 6/14 = 1/14
The Probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.
What is Probability?Probability is "possibility that deals with the chance of occurrence of random event" .
According to the question,
A cube has 6 faces that is (1,2,3,4,5,6). Total number of faces n(s) = 6.
Probability formula = (Number of favorable event)/(Total number of event).
Probability of taking 4, P(4) = 1/6.
A bag containing 8 blue and 6 red balls. Total number of balls in a bag n(s) = 14.
Probability of taking red balls P(red balls) = 6/14.
In order to find that probability of rolling a 4 on a number cube and then choosing a red a ball at random only if multiply P(4) by P(red balls).
P(4) × P(red balls) = [tex]\frac{1}{6}[/tex] × [tex]\frac{6}{14}[/tex] = [tex]\frac{1}{14}[/tex].
Hence, probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.

Which of the following geometric objects occupy one dimension?
Check all that apply.
A. Line
B. Triangle
C. Plane
D. Segment
E. Ray
F. Point
A. Line
D. Segment
E. Ray
Step-by-step explanation:Math dimensions include length, width, and height (in that order). The dimension that an object occupies is dependent on how many different measurements, aka dimensions, an object has.
0th Dimension
The first dimension is actually the zeroth dimension. This dimension includes objects that do not have any measurements. A point does not have a length because it only occupies one spot on a plane.
The 0th dimension includes:
Point1st Dimension
The next dimension, the 1st dimension, has only length. This means the object can travel across the x-axis, but it can only go in one direction.
The 1st dimension includes:
LineSegementRay2nd Dimension
For this question, the last dimension is the 2nd dimension. The 2nd dimension has both length and width. This means that the object occupies both the x and y-axis.
The 2nd dimension includes:
TrianglePlane3rd Dimension
The 3rd dimension is not included in the question or the answer choices but is still important. The 3rd dimension has length, width, and height. This occupies the x, y, and z-axis and cannot be graphed on a regular geometric plane. The 3rd dimension is graphed in a geometric space.
The 3rd dimension includes:
CubePrismWhat is the solution to the given inequality? 1/2-1/4x>-1/4
Answer:
x ≤ 3
Step-by-step explanation:
[tex]\dfrac{1}{2}-\dfrac{1}{4}x \geq -\dfrac{1}{4}[/tex]
Subtract 1/2 from both sides:
[tex]\implies \dfrac{1}{2}-\dfrac{1}{4}x-\dfrac{1}{2} \geq -\dfrac{1}{4}-\dfrac{1}{2}[/tex]
[tex]\implies -\dfrac{1}{4}x \geq -\dfrac{3}{4}[/tex]
Multiply both sides by 4:
[tex]\implies -\dfrac{1}{4}x \cdot 4 \geq -\dfrac{3}{4} \cdot 4[/tex]
[tex]\implies -x \geq -3[/tex]
Divide both sides by -1 (remembering to flip the sign):
[tex]\implies \dfrac{-x}{-1} \geq \dfrac{-3}{-1}[/tex]

A total of 750 tickets were sold for the school play. They were either adult tickets or student tickets. There were 50 more student tickets sold than adult tickets.
How many adult tickets were sold?
1 adult tickets
х
5
?
Answer:
350 adult tickets were sold.
Step-by-step explanation:
Let's set up some values:
x = adult tickets
x + 50 = student tickets, since there were 50 more student tickets than adult tickets.
Now, let's set up our equation. If these two values add up to 750 tickets, then we can conclude the following:
(x) + (x + 50) = 750
2x + 50 = 750
2x = 700
x = 350 adult tickets. This means there were 400 student tickets sold.

P(2) = 4/52P(2) = 1/13P(2) = 0.07692Which best describes the relationship between the lines with equations -9x+9y=1 and 7x+2y=4
Using the slope of each of the lines, the best statement that describes the their relationship is that they are: neither perpendicular nor parallel.
What is the Slope of Parallel and Perpendicular Lines?The slope of parallel lines are the same, while that of perpendicular lines are negative reciprocals.
Given the two lines with the following equations:
-9x+9y=1
7x+2y=4
Rewrite both in slope-intercept form as y = mx + b to determine the slope of each line:
-9x + 9y = 1
9y = 9x + 1
y = 9x/9 + 1/9
y = x + 1/9 (slope = 1)
7x + 2y = 4
2y = -7x + 4
y = -7x/2 + 4/2
y = -7/2x + 2 (slope = -7/2).
The slope of both lines are different, so they are not parallel. So also, their slopes are not negative reciprocals.
Therefore, they are neither perpendicular nor parallel.

There would be a gap in the age of people in an elementary school.
Which option would produce one or more gaps ?
There is a gap in a histogram when there is no data point represented in the data point.
There would be no gap in the ages of students in the sixth grade because their ages would have a range. There would be a gap in the age of people in an elementary school because there would be the ages of the students then the ages of teachers.

Find the 60th term of the following sequence.
8, 16, 24. ...
Answer:
Step-by-step explanation:
Remark
You want the 60th term of the arithmetic (?) sequence given.
Formula
L = a + (n - 1)*d
Givens
L = ?
a = 8
d = 8
n = 60
Solution
L = 8 + (60 - 1)*8
L = 8 + 60*8 - 8
L = 480
Answer
The 60th term is 480
Answer:
Step by step explanation :
As we know
[tex]\:\bf\boxed{an\:=\:a\:+\:(n\:-\:1)\:d}[/tex]
where,
an = the nth term in the sequence
n = the term
d = common difference
a = first term of the AP.
Here,
an = a60
n = 60
d = 16 - 8 = 8
a = 8
Now,
[tex]\:\mathsf{a60\:=\:8\:+\:(60\:-\:1)(8)}[/tex]
=> [tex]\:\mathsf{a60\:=\:8\:+\:(59)(8)}[/tex]
=> [tex]\:\mathsf{a60\:=\:8\:+\:472}[/tex]
=> [tex]\:\bf{a60\:=\:480}[/tex]
Therefore the 60th term of the AP is 480.
In this equation f(x) = 3x -15, what is y if x is 9?
*
Answer:
y = 12
Step-by-step explanation:
To solve this equation... The function is basically:
y = 3x - 15
So by substituting in x=9:
y = 27 - 15 = 12.
y = 12
Hope this helps.
Answer:
y = 12
Step-by-step explanation:
f(x) = y, so to find y, we jut need to substitute 9 for all the x-values in the equation:
f(9) = 3(9) - 15
Simplify:
f(9) = 27 - 15
f(9) = 12
Since f(x) = y
y = 12 when x is 9
