The probability of rolling a 9 or higher on the 3rd roll is 4/27, or approximately 14.8%.
Probability is a branch of mathematics that deals with determining the likelihood or chance of an event occurring. It is often expressed as a fraction or a percentage.
Conditional probability is the probability of an event happening given that another event has already happened.
The probability of not rolling a 9 or higher on the first roll is 8/12 or 2/3, as there are 8 numbers on the cube that are less than 9.
The same is true for the second roll, so the probability of not rolling a 9 or higher on the first two rolls is (2/3) * (2/3) = 4/9.
The probability of rolling a 9 or higher on the third roll is 4/12 or 1/3, as there are 4 numbers on the cube that are 9 or higher.
So, the probability of rolling a 9 or higher on the third roll given that the previous two rolls did not result in a 9 or higher is
=> (4/9) * (1/3) = 4/27

\int x^(2)(1)/(\sqrt(x^(2)-4))dx
The integration of the given equation will be [(1/2) i√3 + 2 log (1 + 3i)].
What is integration?Integration is a way of finding the total by adding or summing the components. It's a reversal of differentiation, in which we break down functions into pieces. This approach is used to calculate the total on a large scale.
The integration equation is given below.
[tex]\begin{aligned} \rm I = \int _1^2 \sqrt{x^2 - 4} \ dx \end{aligned}[/tex]
We know that the formula is given as,
∫√(x² - a²) dx = (x/2)√(x² - a²) + (a² / 2) log [x + √(x² - a²)]
Then by the integration, we can write it as,
[tex]\begin{aligned} \rm I &= \int _1^2 \sqrt{x^2 - 4} \ dx \\\rm I &= \int _1^2 \sqrt{x^2 - 2^2} \dx\\\rm I &= \left [ \dfrac{x}{2}\sqrt{x^2-2^2} + \dfrac{2^2}{2} \log (x + \sqrt{x^2 - 2^2}) \right ]^2_1\\\end{aligned}[/tex]
Simplify the equation further, then we have
I = [(1/2) i√3 + 2 log (1 + 3i)]
The integration of the given equation will be [(1/2) i√3 + 2 log (1 + 3i)].

What is circumference ?Circumference is the distance around the perimeter of a circular object. It is defined as the length of the circle that is found by multiplying the diameter of the circle by π (pi), which is approximately equal to 3.14.
The formula for the circumference of a circle is given by:
C = 2πr,
To calculate the circumference of the circular garden, we can use the formula:
C = 2πr
where C is the circumference, π is the mathematical constant pi (approximated as 3 in this case), and r is the radius. Plugging in the given values, we have:
C = 2 x 3 x 70
= 420 feet
Now, since the flowers are spaced every 4 feet, we can divide the circumference by 4 to find the number of flowers needed:
number of flowers = C / 4
= 420 / 4
= 105
Therefore, 105 flowers spaced every 4 feet are needed to surround a circular garden with a 70-foot radius.

What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
To solve for x in the inequalities:

We'll solve each inequality separately:
5x - 4 ≥ 12
Adding 4 to both sides, we get:
5x ≥ 16
x ≥ 16/5
So the first inequality is solved for x as x ≥ 16/5.
Now, 12x + 5 ≤ -4
Subtracting 5 from both sides, we get:
12x ≤ -9
x≤ -9/12

Step-by-step explanation:
We can find the other point using the axis of symmetry.
The axis of symmetry for a parabola passes through the x coordinate of the vertex.
So our axis of symmetry is x=4, which is a vertical line.
For any point on a parabola curve except the vertex, there will two points that share the same y value. The two x coordinates of those points midpoints should be the axis of symmetry.
So,
If we know (0,-6) and the vertex is 4, let's find the other point
[tex]( \frac{0 + b}{2} = 4[/tex]
[tex]b = 8[/tex]
So our other point is
(8,-6).
So the answer to #1 is we found point (8,-6) by using the axis of symmetry. By reflecting the point (0,-6) about the vertical line x=4, we end up getting the point (8,-6)
To find q, q(x) has the same vertex, so it is (4,10).
We know the axis of symmetry is x=4, we also know the y intercept is 18 so we have point (0,18)
Using the axis of symmetry we will get (8,18).
So the graphs above are the graphs of p and q
The graph facing upwards is q
The graph facing downwards is p.
For #2, you can say we know the vertex is (4,10) and using the y intercept and axis of symmetry we found the other point on the curve.
I don't fully see the table but if the other coordinates have a higher y value, the vertex is a minimum.
Else, of the other coordinates have a lower y value, the vertex is a maximum.

The height of the cylindrical tub of ice cream is 6.75 inches.
What is the surface area of a cylinder?A cylinder is a 3 dimensional shape which has a curved side and two circular surfaces. The total surface area can be determined by the expression;
total surface area of a cylinder = 2πr^2 + 2πrh
where r is the radius of it circular surface, and h is its height.
Considering the given question, we have;
total surface area of a cylinder = 2πr^2 + 2πrh
But total surface area = 183.69 square inches
r = D/2
= 6/ 2
r = 3 inches
Thus,
183.69 = 2*3.14*3^2 + 2*3.14*3*h
= 56.52 + 18.84h
183.69 - 56.52 = 18.84h

Answer: The answer is (C) 6.75
Step-by-step explanation:
The formula for Surface Area is: SA = 2πr^2 + 2πrh
Let's do the first part: 2πr^2
So you need to find the radius, which is half the diameter. 6 is the diameter so half that, and you get 3.
Now, times 3 by itself
3 * 3 = 9
And then times 9 by 2
9 * 2 = 18
And times 18 by pi, 3.14
18 * 3.14 = 56.52
Now that we have our first value, lets move on to the second part of the formula: 2πrh
So we need the diameter, and the question gives us the value of the diameter.
6 is the diameter
so times 6 by pi, 3.14
6 * 3.14 = 18.84h (leave h there because we don't know the height)
Now do this:
183.69 = 56.52 + 18.84h
You cannot add 56.52 and 18.84h because they are not like terms
So take away 56.52 from both sides
56.52 - 56.52 = 0
183.69 - 56.52 = 127.17
Now divide 127.17 by 18.84h
127.17/18.84 = 6.75 inches
