The probability of winning on the first roll is 0.22
Solution-
As in the game of casino, two dice are rolled simultaneously.
So the sample space would be,
|S| = 36
Let E be the event such that the sum of two numbers are 7, so
E = {(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)}
|E| = 6
P(E) = 6/36
Let F be the event such that the sum of two numbers are 11, so
F = {(6,5), (5,6)}
|F| = 2
P(F) = 2/36
Now,
P(E∪F)= 0.22
The probability of winning on the first roll is 0.22

The matrix equation below can be used to solve a system of when your equation what is the solution to the system? [6,4][x]=[1], [9,6][y]=[3]
There is no solution from the given matrix equation.
Solving two by two matrix equations.
In a two by two matrix equation system, two matrices can be multiplied if and only if the number of columns in the first matrix is equal to the number of rows in the second matrix. It implies that the first matrix is 2×2 and the second matrix is 2×1.
Given that:
[tex]\left[\begin{array}{cc}6&4\\9&6\end{array}\right] \left[\begin{array}{c}x\\y \end{array}\right] = \left[\begin{array}{c}1 \\ 3 \end{array}\right][/tex]
We multiply each row in the first matrix by each column in the second matrix, so we get:
[tex]\left[\begin{array}{c}6x+4y\\9x+6y\end{array}\right] = \left[\begin{array}{c}1 \\ 3 \end{array}\right][/tex]
Then, we can express it as a system of linear equations:
6x + 4y = 1 --- (1)
9x + 6y = 3 --- (2)
Here, we decided to use the substitution method to solve the system of equations.
From equation (1)
x = 1/6 - 2y/3
Replace the value of x into equation (2) and solve for y, we get:
9(1/6 - 2y/3) + 6y = 3
By solving it, we get:
3/2 = 3
Thus, since 3/2 = 3 is not a true solution, then we can conclude that there is no solution.

What is the lowest price a dozen eggs could reach before Farmer Johnson would be forced to shut down in the short run? (Please enter your answer without a dollar sign, for values less than 1.00, you must put a 0 before the decimal)
If Farmer Johnson's minimum AVC is, for example, $1.50 per dozen eggs, then any price below $1.50 would result in losses that he could not sustain in the long run.
To determine the lowest price a dozen eggs could reach before Farmer Johnson would be forced to shut down in the short run, we need to know his minimum average variable cost (AVC) of producing eggs.
The average variable cost is the variable cost per unit of output, and it includes costs that vary with the level of production, such as labour, feed, and utilities.
If the price of a dozen eggs falls below the minimum AVC, Farmer Johnson will not be able to cover his variable costs and will incur losses. In the short run, he may continue to produce as long as he can cover his variable costs, but he will eventually be forced to shut down if he cannot cover his fixed costs as well.
Without information on Farmer Johnson's specific costs, we cannot determine the exact minimum AVC or the lowest price at which he would shut down. However, we can say that the lowest price a dozen eggs could reach before he would be forced to shut down is equal to his minimum AVC.
If Farmer Johnson's minimum AVC is, for example, $1.50 per dozen eggs, then any price below $1.50 would result in losses that he could not sustain in the long run.

Carter was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 31%. What number should he multiply the cost of the meal by to find the total plus tip in one step?
The total cost of the meal is $65.50, with tip included.
Here, in this question we need to find the percentage Value, to find the total cost of the meal plus the tip, Carter needs to multiply the cost of the meal by a factor of 1 + the tip percentage, which is 1 + 31% = 1.31.
So, the number Carter should multiply the cost of the meal by to find the total plus tip in one step is 1.31.
For example, if the cost of the meal was $50, then the total cost including the tip would be addition of cost of meal and tip.
Total cost = Cost of meal + Tip
Total cost = $50 + 31% of $50
Total cost = $50 + $15.50

Answer:
We can use the binomial probability formula to find the probability of getting exactly 3 blue marbles in two draws:
P(X=3) = (2 choose 3) * (0.6)^3 * (0.4)^(-1) = 0.288
However, since we are asked for the probability of the random variable having an outcome of 3 (i.e. getting exactly 3 blue marbles), we can simply use this probability:
P(X=3) = 28.8%
Therefore, the answer is (a) 24%.
un automóvil que se desplaza en una pista recta aumenta su velocidad de 15 m/s a 45 m/s utilizando para ello un
po de 10 segundos. Consideremos que la aceleración fue uniforme, calcula:
aceleración en dicho tiempo.
The acceleration of the car at that time was 3 m/s².
We have,
From the kinematic equation to find the acceleration:
v = u + at
where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
Initial velocity u = 15 m/s
Final velocity v = 45 m/s,
Time t = 10 s
We can rearrange the equation to solve for acceleration:
a = (v - u) / t
Substituting the values, we get:
a = (45 m/s - 15 m/s) / 10 s
a = 3 m/s^2
Therefore,

Answer:
1(.1) + 2(.2) + 3(.3) + 4(.4)
= .1 + .4 + .9 + 1.6 = 3.0
Answer:
Step-by-step explanation:
To calculate the weighted mean, first multiply each number by its corresponding weight, then add-up the products and divide by the sum of the weights-
weighted mean = (1 x 0.1 + 2 x 0.2 + 3 x 0.3 + 4 x 0.4) / (0.1 + 0.2 + 0.3 + 0.4)
Then simplifying the numerator:-
weighted mean = (0.1 + 0.4 + 0.9 + 1.6) / (0.1 + 0.2 + 0.3 + 0.4)
Then adding up the numerator:-
weighted mean = 3 / 1So the weighted mean of the numbers 1, 2, 3, and 4 with weights 0.1, 0.2, 0.3, and 0.4 respectively is 3.

The wood of a sequoia tree has a density of about 450
kilograms per cubic meter.
mowans "rlod bnia Streishib el ribirW S
The mass of the trunk of the sequoia tree is 141443.1 kg.
The volume of a cylinder, using the formula:
V = πr²h
π is pi (approximately 3.14)
r is the radius of the trunk (which is half the diameter)
h is the height of the trunk
1 meter = 3.28084 feet
we can convert the given measurements from feet to meters to ensure consistent units.
The base diameter of the tree is 12.2 meters / 3.28084 = 3.719 meters,
so the radius is 3.719 / 2 = 1.8595 meters.
The height of the tree is 95 meters / 3.28084 = 28.9568 meters.
Therefore, the volume of the trunk is:
V = π(1.8595)²(28.9568) = 314.318 cubic meters
Now calculate the mass of the trunk by multiplying the volume by the density of the wood:
M = V × ρ

The solution of the expression is 3.659
First, we will start with the expression inside the brackets, i.e., [(3 1/3 * 1.9) + (19.5 / (4 1/2)]. Here, we have two operations - multiplication and division. According to PEMDAS, we need to perform multiplication before division.
To simplify this expression, we will first convert 3 1/3 to an improper fraction. 3 1/3 is the same as 10/3. Therefore, the expression inside the brackets becomes
=> [(10/3 * 1.9) + (19.5 / (9/2)].
Next, we will simplify the multiplication first -
=> 10/3 * 1.9 = 19/3.
Now, let's simplify the division operation
=> 19.5 / (9/2) = 4.33
Therefore, the expression inside the brackets becomes
=> [(19/3) + 4.33] = 8.99
Moving on to the denominator of the given expression
=> [62/75 - 0.16]. Here, we need to perform subtraction first as it comes before division in PEMDAS.
62/75 = 0.8266
Therefore, the denominator of the given expression becomes
=> [0.8266 - 0.16] = 0.6666
Now, let's simplify the numerator of the given expression. We have
=> [(3.5 + 4 2/3 + 2 2/15) / (0.5 * (1 1/20 + 4.1))].
Let's first convert all the mixed fractions to improper fractions.
3.5 can be written as 7/2, 4 2/3 can be written as 14/3, and 2 2/15 can be written as 32/15.
Therefore, the numerator becomes
=> [(7/2 + 14/3 + 32/15) / (0.5 * (21/20 + 4.1))].
Let's first simplify the expression inside the brackets
=> 21/20 + 4.1 = 5.15.
Therefore, the numerator becomes
=> [(7/2 + 14/3 + 32/15) / (0.5 * 5.15)].
Now, let's simplify the addition operation in the numerator. We need to find a common denominator to add the fractions.
The common denominator for 2, 3, and 15 is 30.
Therefore, (7/2 + 14/3 + 32/15) can be written as
=> (105/30 + 140/30 + 64/30).
Adding the fractions, we get (309/30).
Therefore, the numerator becomes [(309// (0.5 * 5.15)].
Next, let's simplify the expression inside the brackets - 0.5 * 5.15 = 2.575.
Therefore, the numerator becomes
[(309/30) / 2.575] = 3.68
Now that we have simplified the numerator and denominator of the given expression separately, we can simplify the entire expression.
[(8.99) / (0.6666)] / [3.68]
Let's first simplify the expression inside the first set of brackets.
(8.99) / (0.6666) = 13.486
Therefore, the given expression becomes 13.486 / 3.68 = 3.659

Find the equation of the line joining the points (1,6) and (6,1)
Step-by-step explanation:
in what form do you need the equation ?
I assume it is the slope-intercept form :
y = ax + b
"a" being the slope of the line, "b" being the y-intercept of the line.
the slope of a line is the ratio
y-coordinate difference / x-coordinate difference
when going from one point on the line to another.
and the y-intercept (y-axis intercept, to be precise) is the y-value when x = 0.
so, starting with the slope, we go for example from (1, 6) to (6, 1) :
x changes by +5 (from 1 to 6).
y changes by -5 (from 6 to 1).
so, the slope is
-5/+5 = -1
so, we know, our equation looks like
y = -x + b
to get "b" we use one of the points, e.g. (1, 6) :
6 = -1 + b
b = 7
and our final equation is
y = -x + 7
