A single number cube is rolled twice. The 36 equally-likely outcomes are shown to the right. What is the first step in finding the probability of getting two numbers whose sum is 12? Find the probability of getting two numbers whose sum is 12.
The probability of getting two numbers whose sum is 12 when rolling a single number cube twice is 1/36.
To find the probability of getting two numbers whose sum is 12 when a single number cube is rolled twice, we'll first need to identify the favorable outcomes.
A number cube has six faces, numbered from 1 to 6. When it is rolled twice, there are 6 x 6 = 36 equally-likely outcomes. To find the probability, we can use the formula:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
The first step is to identify the favorable outcomes, which are the pairs of numbers that add up to 12. Since we are dealing with a number cube that has faces numbered 1 to 6, there is only one possible pair that satisfies this condition: (6,6).
Now that we have determined the favorable outcome, we can find the probability:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
Probability = 1 (for the pair 6,6) / 36
Thus, the probability of getting two numbers whose sum is 12 when rolling a single number cube twice is 1/36.

Determine o valor das letras para que a sequencia 4,8,a,18 seja inversamente proporcional a sequencia 54,b,24,c
Answer:
Step-by-step explanation:
The values of the letters are: a = k / (648b), b = k / (1296c), c = k / (1296b) and 24c = k / (576a).
To determine the value of the letters in the given sequences, we need to first recall the formula for inverse proportionality, which states that the product of the terms in one sequence is equal to the constant value of the product of the terms in the other sequence. Mathematically, we can represent this as:
4 x 8 x a x 18 = k = 54 x b x 24 x c
Here, k is the constant of proportionality. To find the value of the letters, we can solve for them algebraically. First, we can simplify the equation by dividing both sides by 4 x 18 x 24:
a = k / (4 x 8 x 18 x 24 / 54 x b x c)
a = k / (6b c)
Next, we can substitute the given values of the sequence into the equation and simplify:
a = k / (6b c) = k / (648b)
Multiplying both sides by 648b, we get:
648b a = k
Similarly, we can solve for the values of the other letters as follows:
b = k / (54 x 24 x c) = k / (1296c)
24c = k / (4 x 8 x a x 18) = k / (576a)
c = k / (54 x b x 24) = k / (1296b)
Therefore, the values of the letters are:
a = k / (648b)
b = k / (1296c)
c = k / (1296b)
24c = k / (576a)

A solid is made by a hemisphere and cylinder having equal radii. The volume of the solid is 2707 cm'. If the height of the cylinder is 80 cm, find the total surface area of the solid
The total surface area of the solid is approximately 1818 [tex]cm^{2}[/tex]. Let's call the radius of the hemisphere and cylinder "r".
The volume of the solid is the sum of the volumes of the hemisphere and cylinder: V = (2/3)π[tex]r^{3}[/tex] + π[tex]r^{2}[/tex]h. Substituting in the given values, we get: 2707 = (2/3)π [tex]r^{3}[/tex] + π[tex]r^{2}[/tex](80)
To solve for r, we can rearrange the equation and use a numerical method or calculator. We get: r ≈ 11.6 cm
Now, we can use the radius to find the surface area of the solid. The surface area is the sum of the curved surface areas of the hemisphere and cylinder, plus the area of the circular base of the cylinder: A = 2π[tex]r^{2}[/tex] + 2πrh + π[tex]r^{2}[/tex].
Substituting in the given values and solving for A, we get: A ≈ 1818 [tex]cm^{2}[/tex]. Therefore, the total surface area of the solid is approximately 1818 [tex]cm^{2}[/tex].

A fisherman recorded the weight of each black bass he caught during a fishing trip: {12, 7, 8, 13, 6, 14}
The median weight of the black bass caught by the fisherman is 10.5 pounds.
To find the median, we need to arrange the weights in order from smallest to largest: {6, 7, 8, 12, 13, 14}. Since there are an even number of weights, the median is the average of the two middle values, which are 8 and 12. Therefore, the median weight is (8+12)/2 = 10.5 pounds.
The median is a measure of central tendency that represents the middle value in a dataset. It is less sensitive to extreme values than the mean and is useful for describing the typical value in a skewed distribution.
In this case, the median weight of 10.5 pounds indicates that half of the black bass caught by the fisherman weighed less than 10.5 pounds, and half weighed more than 10.5 pounds.

The mean of six values is 7. There is one outlier that
pulls the mean higher than the center. What could the
data set be? What is the mean without the outlier?
The data set is 2, 7, 7, 8, 9, and 9, with a mean of 7. The outlier is 2, and the mean without the outlier is 6.6. The outlier pulls the mean lower than the center, but once removed, the mean becomes more representative of the data set.
To find the mean of a set of values, we add up all the values and divide by the total number of values.
In this case, we know that the mean of six values is 7, so we can set up the following equation
(2 + 7 + 7 + 8 + 9 + 9) / 6 = 7
Simplifying the equation, we get
42 / 6 = 7
So, the sum of the six values is 42.
Now, we know that there is one outlier that pulls the mean higher than the center. In other words, one of the values is much larger than the others. Let's assume that the outlier is 20.
So, the new sum of the six values would be
2 + 7 + 7 + 8 + 9 + 20 = 53
To find the mean without the outlier, we need to subtract the outlier from the sum and divide by the remaining number of values. In this case, there are five values remaining. So, we get
(2 + 7 + 7 + 8 + 9) / 5 = 33 / 5 = 6.6
Therefore, the possible data set is 2, 7, 7, 8, 9, and 9, and the mean without the outlier is 6.6.

A semi-elliptic archway has a height of 15 feet
at the center and a width of 50 feet, as shown
in the figure. The 50-foot width consists of a
two-lane road. Can a truck that is 12 feet high
and 14 feet wide drive under the archway
without going into the other lane?
Since 1.1584 > 1, the truck cannot pass under the archway without going into the other lane.
A semi-elliptic archway with a height of 15 feet at the center and a width of 50 feet can be visualized as half of an ellipse.
The major axis of the ellipse corresponds to the width, while the minor axis corresponds to the height. In this case, the major axis (a) is 25 feet, and the minor axis (b) is 15 feet.
To determine if a truck that is 12 feet high and 14 feet wide can drive under the archway without going into the other lane, we can use the equation of an ellipse: (x²/a²) + (y²/b²) = 1.
The truck will occupy half of the road width, which is 25 feet, so its horizontal distance from the center (x) is 25 - 7 = 18 feet, and its height (y) is 12 feet.
Plugging these values into the equation, we get: (18²/25²) + (12²/15²) = (324/625) + (144/225) ≈ 0.5184 + 0.64 = 1.1584.

Given: (x is number of items) Demand function: d(x) = 588.7 – 0.4x2 Supply function: 8(x) = 0.322 2 Find the equilibrium quantity: Find the producers surplus at the equilibrium quantity:
The equilibrium quantity is approximately 34.47 items and the producer surplus at the equilibrium quantity is approximately 396.11.
How to find equilibrium quantity and producer surplus?To find the equilibrium quantity, we need to find the quantity at which the demand and supply functions are equal:
Demand function: d(x) = 588.7 – 0.4x^2
Supply function: s(x) = 8(x) = 0.322
Setting these two functions equal to each other, we get:
588.7 – 0.4x^2 = 0.322x
Simplifying this equation, we get:
0.4x^2 + 0.322x - 588.7 = 0
Using the quadratic formula, we get:
x = (-0.322 ± √(0.322^2 + 40.4588.7)) / (2*0.4)
x ≈ 34.47 or x ≈ -43.67
Since we cannot have a negative quantity, the equilibrium quantity is approximately 34.47 items.
To find the producer surplus at the equilibrium quantity, we need to calculate the area between the supply curve and the equilibrium price, which is the price that corresponds to the equilibrium quantity. We can find the equilibrium price by plugging the equilibrium quantity into either the demand or supply function:
s(34.47) = 8(34.47) = 11.58
So the equilibrium price is approximately 11.58.
Now we can find the producer surplus by integrating the supply function from 0 to the equilibrium quantity, and subtracting the result from the area of a rectangle with height equal to the equilibrium price and width equal to the equilibrium quantity. The formula for producer surplus is:
Producer Surplus = (Equilibrium Price * Equilibrium Quantity) - ∫[0, Equilibrium Quantity] Supply Function dx
Plugging in the values we found, we get:
Producer Surplus = (11.58 * 34.47) - ∫[0, 34.47] 0.322 dx
Integrating the supply function, we get:
∫[0, 34.47] 0.322 dx = 0.322 * 34.47 ≈ 11.10
So the producer surplus is:
Producer Surplus ≈ (11.58 * 34.47) - 11.10 ≈ 396.11
Therefore, the equilibrium quantity is approximately 34.47 items, and the producer surplus at the equilibrium quantity is approximately 396.11.

Answer:2.78
Step-by-step explanation:
the probability of rolling a 5 on a six-sided die and then rolling a 2? The chances of rolling a 5 on the first die is 1 in 6. The chances of rolling a 2 on the second roll in 1 in 6. So the probability of a 5, then a 2, is 1 in 36.
We can see that this gives us the exact same answer as the first method: 1/36 as a percentage is 2.78%.
Answer:
A) [tex]2.78\%[/tex]
Step-by-step explanation:
Assuming that Chris throws two standard dices (meaning 6 sides, with the sides numbered as 1, 2, 3, 4, 5, 6, respectively). There is one chance of the dice landing on a 5 for both dices, and presuming that the dices do not hit each other, would be independent variables. This means that there is a 1/6 chance for both:
[tex]\frac{1}{6} * \frac{1}{6} = \frac{1}{36}[/tex]
Change the fraction to a percentage. Divide and solve for a decimal. Then, move the decimal point to the left two place values, and you will obtain your percentage:
[tex]\frac{1}{3} = 0.02777 = 2.777\%[/tex]
You are rounding to the nearest tenth place value (2nd place value right of the decimal point):
[tex]2.777\% = 2.78\%[/tex]
[tex]2.78\%[/tex] is your answer, or A).
