The probability of drawing a red marble followed by a blue marble from a bag containing 4 red, 3 yellow, and 7 blue marbles can be calculated using the formula for conditional probability. Finally, we multiply these two probabilities together to get the joint probability of drawing a red marble followed by a blue marble, which is 14/91 or approximately 0.1538.

The probability of drawing a red marble on the first draw is 4/14 (or simplifying, 2/7) since there are 4 red marbles out of 14 total marbles in the bag. After the first marble is drawn, there are now 13 marbles left in the bag, with 7 of them being blue. Therefore, the probability of drawing a blue marble on the second draw given that a red marble was drawn on the first draw is 7/13. Multiplying these probabilities together gives us the joint probability of drawing a red marble followed by a blue marble: (2/7) * (7/13) = 14/91 or approximately 0.1538.

JK + KL = JL , substitute values

2x + 1 + 6x = 81, that is

8x + 1 = 81 ( subtract 1 from both sides )

8x = 80 ( divide both sides by 8 )

x = 10

Thus JK = 2x + 2 = 2(10) + 1 = 20 + 1 = 21

KL = 6x = 6 × 10 = 60

--------------------------------------------------------------

16

JK + KL = JL , substitute values

2x + x + 2 = 5x - 10 , that is

3x + 2 = 5x - 10 ( subtract 3x from both sides )

2 = 2x - 10 ( add 10 to both sides )

12 = 2x ( divide both sides by 2 )

6 = x

Thus

JK = 2X = 2 × 6 = 12

KL = x + 2 = 6 + 2 = 8

JL = 5x - 10 = 5(6) - 10 = 30 - 10 = 20

Answer:

20 cm^2.

Step-by-step explanation:

If the scale factor is 2 each of the sides of the figure will be increased by a factor 2.

So each side will have a length of 2 * 1 = 2 centimeters.

It will consist of 5 squares of dimension 2*2 =  an area of 4 cm^2

So the area of the new cross  is 5*4 = 20 cm^2.

We can also calculate the area directly by multiplying  by 2^2 ( the scale factor)squared.)

The original area = 5 so the area of the enlarged figure = 5 * 2^2 = 20 cm^2.

240 is the answer you're looking for!

Step-by-step explanation:

To find the area, spilt the trapezoid into 3 shapes.

2 triangles (at the ends) and 1 rectangle (the center).

Let's start with the rectangle, the formula for rectangle area is:

\(l*w=A\)

The length of the rectangle is 12, the width is 20. Add the numbers in:

\(12*20=A\)

Solve:

\(12*20=240\)

The area of the rectangle is 240. Now solve for the Triangles.

The formula for finding the area of triangles are is:

\((L*W)/2\)

The length of the triangle is 12. To find the width subtract 20 from 30.

L = 12, W = 10. Add in the numbers.

\((12*10)/2 = A\)

Use order of operations to solve, start with parenthesis:

\(120/2=A\)

Rember to divide it by 2 because a triangle is half of a rectangle.

\(60 =A\)

Since there are two identical triangles, you don't need to solve for the other

Now, add the areas together:

\(60 + 120+60=A\)

Then solve:

\(180+60=A\)

\(240=A\)

The correct answer is 240.

Yes, because it only has a single expression, although the division sign might not count….

a.  it implies that the matrix A - XI is not invertible. b)  the determinant of A - XI is zero. c) the equation: .2A - 1 = 0 d) the eigenvalue of matrix A is 5. e)  the eigenvalue of matrix A is 2. f) the eigenvalues of matrix A are X = 0 and X = 1.

a. If there is a nonzero solution to the homogeneous equation (A - XI)v = 0, where X is an eigenvalue of the matrix A, it implies that the matrix A - XI is not invertible. This is because for a matrix to be invertible, its determinant must be nonzero.

If there exists a nonzero solution to the homogeneous equation, it means that the determinant of A - XI is zero, indicating that A - XI is singular and not invertible.

b. If there is a nonzero solution to the homogeneous equation (A - XI)v = 0, it implies that the determinant of A - XI is zero. This is because the homogeneous equation represents a system of linear equations, and the determinant of the coefficient matrix (A - XI) being zero implies that the system has a nontrivial solution. Therefore, we can conclude that the determinant det(A - XI) must be zero.

c. Given the matrix A - AI = [1 2 2 1] - A [1 0 0 1] = ['- .2 1 -A'], to find the determinant det(A - 1), we substitute the value X = 1 into the matrix A - XI and compute its determinant. Evaluating the determinant, we have:

det(A - XI) = det(['- .2 1 -A']) = (-.2)(-A) - (1)(1) = .2A - 1

Setting this determinant equal to zero, we obtain the equation:

.2A - 1 = 0

d. Using the equation .2A - 1 = 0 obtained from the previous part, we solve it to find the eigenvalues by setting the determinant det(A - XI) = 0:

.2A - 1 = 0

.2A = 1

A = 1/.2

A = 5

Therefore, the eigenvalue of matrix A is 5.

e. For the matrix A = [2 0 1 2], we can find its eigenvalues by solving the equation det(A - XI) = 0:

det(A - XI) = det([2 0 1 2] - X [1 0 0 1]) = det([2-X 0 1 2-X])

Expanding the determinant, we have:

(2-X)(2-X) - (0)(1) = 0

(2-X)^2 - 0 = 0

(2-X)^2 = 0

Taking the square root, we get:

2-X = 0

X = 2

Therefore, the eigenvalue of matrix A is 2.

f. For the matrix A = [0 1 0 1], we can find its eigenvalues by solving the equation det(A - XI) = 0:

det(A - XI) = det([0 1 0 1] - X [1 0 0 1]) = det([-X 1 0 1-X])

Expanding the determinant, we have:

(-X)(1-X) - (1)(0) = 0

X^2 - X = 0

Factoring out X, we get:

X(X - 1) = 0

Therefore, the eigenvalues of matrix A are X = 0 and X = 1.

So, your first move should be to remove a number of sticks that is less than or equal to 21, but also leaves your opponent with 4 sticks or more. This will set you up for success in the game.

The first few numbers in the Fibonacci sequence are: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on. To determine the number of sticks a player can remove, they look at the previous two numbers in the sequence and add them together. For example, if the previous two numbers were 3 and 5, the player could remove 8 sticks.

To start, we need to find the largest number in the Fibonacci sequence that is less than or equal to 500. Looking at the sequence, we see that 21 is the largest number that fits this criteria. Therefore, on your first move, you can remove up to 21 sticks from the pile.

But should you remove all 21 sticks? Not necessarily. In Fibonacci nim, it is often advantageous to leave your opponent with a certain number of sticks that will force them to make a move that is disadvantageous. One such number is 4. If you can leave your opponent with 4 sticks, they will be forced to remove all 4 and you willbe left with a favorable position.

So, your first move should be to remove a number of sticks that is less than or equal to 21, but also leaves your opponent with 4 sticks or more. This will set you up for success in the game.

Step-by-step explanation:

To determine the number of 9s between 1 and 100, we can consider the numbers from 1 to 99 since we want to exclude 100.

In the range from 1 to 99, we can observe the following patterns:

There is one 9 in each of the units' places (9, 19, 29, ..., 89, 99), giving us 10 occurrences.

There is one 9 in each of the tens' places (90, 91, 92, ..., 99), giving us 10 occurrences.

Therefore, there are a total of 10 + 10 = 20 occurrences of the digit 9 between 1 and 100.

The time takes by car to cover the distance between two cities by car varies inversely with the speed of car. Total 5 hours will consume to complete the trip with a car moving at 40 mph.

Time is taken in traveling a particular distance is proportional to the distance traveled which means more distance covered in more time.

The speed of an object is defined as the 'distance traveled per unit time'. Formula is written as \(Speed(s ) = \frac{Distance(d)}{Time(t)}\)

Now, Speed of car (s) = 50 miles per hour

Car takes 4 hours to complete the trip. Let the distance travelled by car in 4 hour during the trip be 'x'. Applying the speed formula, \(50 mph = \frac{ x}{4 \: \: hours}\)

=> x = 4 × 50 miles

=> x = 200 miles

Now, if the speed of car (s') = 40 mph in the trip. We have to determine the time taken by car to complete the trip with 40 mph speed. So, we know the speed of car and total distance travelled by car on trip. Using the time formula,\(time ( t') = \frac{distance (x) }{ speed( s')} \)

=> \( time (t') = \frac{ 200 \: miles}{ 40 \: mph}\)

= 5 hours.

The probability of reaching into the bag and randomly withdrawing 12 jellybeans such that the number of red ones is 2, the number of orange ones is 5, and the number of green ones is 5

A bag contains, red jelly beans = 7.

On that same bag, Orange jelly beans = 10.

The number of green jelly beans contains in a bag = 7.

Here we have to determine the probability of reaching into the bag and randomly withdrawing 12 jellybeans such that the number of red ones is 2, the number of orange ones is 5, and the number of green ones is 5.

Probability of selecting red ones 2 among 7 = \(7_{C_2}\)

= \($\frac{7!}{2!(7-2) !}\)

Probability of selecting red ones = 21.

Probability of selecting orange ones 5 among 10 = \(10_{C_5}\)

= \($\frac{10!}{5!(10-5) !}\)

Probability of selecting Orange ones = 252.

Probability of selecting green ones 5 among 7 = \(7_{C_5}\)

= \($\frac{7 !}{5 !(7-5) ! }$\)

Probability of selecting green ones = 21.

Total jelly beans = 7 + 10 + 7 = 24.

P(event) = \($\frac{\text { Favorable events }}{\text { total events }} \\\)

\($& =\frac{21 \times 252 \times 21}{24 c_{12}} \\\)
