Two 6-sided dice are rolled. What is the probability that the sum of the two numbers on the dice will be greater than 9?
Answer:
The probability that the sum of the two numbers on the dice will be greater than 9 is 16.7%.
Step-by-step explanation:
To find the probability of the two fair six-sided dice getting a sum of 9 when thrown, we have to first find all the possibilities and those that are greater than 9.
The total number of possibilities for the outcome of the two dice would be (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1) and so on. Due to every possibility from the first dice branching out into six possibilities for the second dice, we can find the total number of possibilities to be 6 * 6 = 36 possibilities.
Now to find the total number of possibilities with a sum greater than 9. Due to the question asking for a sum of over 9, the possibilities will not include those with a sum of 9 itself. Hence, the only possibilities are when the first dice rolls 4 or more, since 3 + 6 (the maximum that the second dice can roll) is exactly 9.
Listing out all the possibilities, there are: (4, 6), (5, 5), (5, 6), (6, 4), (6, 5) and (6, 6). A total of 6 possibilities will get you a sum of 9 or above.
Finally, to find the percentage, we divide the number of possibilities with their sum over 9 by the total number of possibilities:
\(\frac{6}{36} \cdot 100\%\)
\(= \frac{1}{6} \cdot 100\%\)
\(= 16.7\%\)
Hence, the probability that the sum of the two numbers on the dice will be greater than 9 is 16.7%.
Hope this helped!

What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that, two dies are rolled we need to find the probability that the sum of the two numbers on the dice will be greater than 9,
The total outcomes = 36

[5][1], [5][2], [5][3], [5][4], [5][5], [5][6],
[6][1], [6][2], [6][3], [6][4], [6][5], [6][6].}
Listing out all the possibilities, there are: {(4, 6), (5, 5), (5, 6), (6, 4), (6, 5) and (6, 6)} = 6
Therefore, the probability that the sum of the two numbers on the dice will be greater than 9 = 6/36 = 1/6
Hence, the probability that the sum of the two numbers on the dice will be greater than is 1/6

Help I’m failing math
Step-by-step explanation:
the answer is 72.70 cents
Answer: See explanation
Step-by-step explanation:
Markup is 39% of the cost.
Markup is what is added to the price to get the retail price.
39% × 72.72
0.39 × 72.72 = 28.3608
28.3608 ≈ 28. 36
Markup ≈ $28.36
Retail price is the price you get after you add the markup to the original price.
Retail price: Cost + Markup
Retail price: $72.72 + $28.36
Retail price = $101.08
The equation C=24n+2 represents the cost
Jim did not buy any tickets (n_Jim = 0).
Larry bought 7 more tickets than Jim.
To determine the number of tickets Larry bought more than Jim, we need to find the values of n for Larry and Jim's ticket purchases.
For Larry:
Let's substitute C = $170 into the equation C = 24n + 2 and solve for n:
$170 = 24n + 2
Subtracting 2 from both sides:
$168 = 24n
Dividing both sides by 24:
n = 7
For Jim:
We can calculate the number of tickets Jim bought by subtracting 12 from Larry's number of tickets:
n_Jim = n_Larry - 12
n_Jim = 7 - 12
n_Jim = -5
Since we cannot have a negative number of tickets, we can conclude that Jim did not buy any tickets (n_Jim = 0).
To find the difference in the number of tickets bought, we subtract the number of tickets Jim bought from the number of tickets Larry bought:
n_difference = n_Larry - n_Jim
n_difference = 7 - 0
n_difference = 7
Therefore, Larry bought 7 more tickets than Jim.

That means:
Angle 2 is 23 degrees Supplementary Angles
Angle 3 is 157 degrees Vertical Angle to Angle 1
Angle 4 is 23 degrees Vertical angle to Angle 2
Answers:
angle 2 = 23 degreesangle 3 = 157 degreesangle 4 = 23 degrees=======================================================
Explanation:
Angles 1 and 2 are supplementary as they form a straight line. So the angles add to 180
(angle1)+(angle2) = 180
angle2 = 180-(angle1)
angle2 = 180-157
angle2 = 23 degrees
Angle 4 is congruent to this because angles 2 and 4 are vertical angles. Vertical angles are always congruent. Note how angles 1 and 4 are supplementary.
Since angles 1 and 3 are the other pair of vertical angles, this must mean angle 3 is 157 degrees.

Answer:
(7,-6)
x = 7, y = -6
Step-by-step explanation:
(1) 6x - 5y = 72
(2) 2x + 6y = -22
multiply equation (2) by -3
-3 (2x + 6y = -22)
-6x - 18y = 66
add equation (1) and the new equation:
6x + -6x = 0
-5y + -18y = -23y
72 + 66 = 138
---> -23y = 138
divide both sides by -23
y = -6
plug in y = -6 into equation (2):
2x + 6(-6) = -22
2x - 36 = -22

examine the function for relative extrema and saddle points. (if an answer does not exist, enter dne.) f(x, y)
For the given function, the critical point is (-1,2), relative extrema is is 2, and saddle points is zero.
To find the critical points of a function, we need to find where the partial derivatives of the function are equal to zero or do not exist. In other words, we need to find the points where the function is not changing with respect to x and y. The partial derivative of f(x,y) with respect to x is:
fx = 2x + 2
And the partial derivative of f(x,y) with respect to y is:
fy = 2y - 4
To find the critical points, we set both partial derivatives to zero and solve for x and y:
fx = 2x + 2 = 0
=> x = -1
fy = 2y - 4 = 0
=> y = 2
So, the critical point of the function is (-1, 2).
To determine whether this critical point is a relative maximum, minimum, or saddle point, we need to look at the second partial derivatives of the function. The second partial derivative of f(x,y) with respect to x is:
fx = 2
And the second partial derivative of f(x,y) with respect to y is:
fy = 2
The mixed partial derivative of f(x,y) with respect to x and y is:
fy = 0
To classify the critical point, we can use the second derivative test.
If fx and fy are both positive (or both negative) at the critical point, then the critical point is a relative minimum (or maximum), respectively.
If fx and fy have different signs, then the critical point is a saddle point. If the second derivative test is inconclusive, then we need to use additional methods to determine the nature of the critical point.

So we can set up the equation;
x% · 500 = 105
\(\frac{x}{100}\) · 500 = 105
x · 5 = 105

ValueThe value shown (₹ 2,00,000) is (100/3)% more than the actual value, so the relation is ...
₹ 2,00,000 = actual value + (100/3)% × actual value
₹ 2,00,000 = actual value · (1 +1/3)
Multiplying by 1/(1 +1/3), we have ...
actual value = (3/4)·(₹ 2,00,000) = ₹ 1,50,000
The value of machinery to be shown in the New Balance Sheet is ₹1,50,000.

The measure of side length EF in the right triangle is 24.
What is the measure of side length EF?The Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
It is expressed as;
c² = a² + b²
From the diagram:
Hypotenuse DE = c = 26
Leg DF = a = 10
Leg EF = b = ?
Plug in the values and solve for b:
c² = a² + b²
26² = 10² + b²
676 = 100 + b²
b² = 676 - 100
b² = 576
b = +√576 ( we take the positive value since we are dealing with dimensions)
b = 24
Therefore, the length EF is 24.
