a) The probability of selecting two different colors is obtained as 9/10.

b) The probability of not selecting a yellow marble is obtained as 3/20.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

a) To find the probability of selecting two different colors, we can use the complement rule, which states that the probability of an event happening is equal to 1 minus the probability of the event not happening.

So the probability of selecting two different colors can be found by calculating the probability of selecting two marbles of the same color and subtracting that from 1.

The probability of selecting two marbles of the same color from the first bag is (2/5) x (1/4) = 1/10, since there are 2 red marbles out of 5 total marbles in the bag, and the probability of selecting a second red marble is 1/4.

The probability of selecting two marbles of the same color from the second bag is 0, since there is only one marble of each color.

So the probability of selecting two different colors is -

1 - (1/10 + 0) = 9/10

Therefore, the probability value is 9/10.

b) To find the probability of not selecting a yellow marble, we can again use the complement rule.

The probability of not selecting a yellow marble is equal to 1 minus the probability of selecting a yellow marble from either bag.

The probability of selecting a yellow marble from the first bag is 1/5, since there is one yellow marble out of 5 total marbles in the bag.

The probability of selecting a yellow marble from the second bag is also 1/4, since there is one yellow marble out of 4 total marbles in the bag.

So the probability of not selecting a yellow marble is -

1 - (1/5 + 1/4) = 3/20

Therefore, the probability value is 3/20.

The unit rate of running 2.3 km in 7 minutes is 5.48 metres per second.

Unit rate can be defined as a measure used to represent how many units of one type of quantity corresponds to one unit of anther type of quantity.

Here the distance is given in kilometres (km) which can be converted into metres by multiplying by 1000 as,

2.3 km = 2.3*1000 metres

= 2300 metres

Here the time taken to cover 2.3 km is 7 minutes which can be converted ito seconds by multiplying by 60 as,

7 minutes= 7*60 seconds

= 420 seconds

Hence the unit rate of running 2.3 km in 7 minutes expressed in metre per second is calculated as = 2300 metres / 420 seconds

= 5.4761 metres per second

= 5.48 metres per second (approximately)

(a) The height of the ball when it leaves the child's hand is 3 feet.

(b) The maximum height of the ball is 19 feet.

(c) The ball will strike the ground approximately 33.44 feet from the child.

(a) This is because when x = 0 (the point at which the ball is thrown), the equation simplifies to y = 3.

(b) The maximum height of the ball can be found by finding the vertex of the parabola. The x-coordinate of the vertex is -b/2a, where a = -1/16 and b = 2. So, x = -2/(-1/8) = 16. Plugging this value back into the equation gives us the maximum height: y = -1/16(16)² + 2(16) + 3 = 19 feet.

(c) The ball strikes the ground when y = 0. Setting the equation equal to 0 and solving for x gives us:

0 = -1/16 x² + 2x + 3

Multiplying both sides by 16 to eliminate the fraction gives us:

0 = -x² + 32x + 48 = x² - 32x - 48

Using the quadratic formula, we find that x = (32 ± 8√19)/2 or x ≈ 33.44 and x ≈ -1.44

Taking the positive value, the distance from the child to where the ball strikes the ground is approximately 33.44 feet.

Answer:

1 < x < 15

Step-by-step explanation:

To find the range of values for the third side, you must subtract and add the other known sides. The lower limit for the range of the third side will be 8 - 7, which equals 1. The upper limit for the range of the third side will be 8 + 7, which equals 15

Answer:

1<x<15

Step-by-step explanation:

Triangle inequalities state that the sum of two sides of any triangle must be less than the other. This is true for all three sides of the triangle.

In this case, we know two sides. Let us set a variable for the third, as x.

So the sum of 8 and 7 has to be bigger than x:

8+7>x

15>x

8 and x have to be greater than 7:

8 +x >7

x>-1

And 7 and x have to be greater than 8:

7 + x>8

x>1

Looking at the inequalities between x, we must choose the most inclusive ones. x>-1, but 1 is within that, so we can go with x>1. x<15 is a statement that cannot change because it is the only end value given. Therefore, the answer is 1<x<15

The simplified expression is (-64[tex]m^{(10)}[/tex])/([tex]n^{(14)}[/tex]).

The given expression is ((-4m4n-4)3) / ((mn)2).

To simplify the expression ((-4[tex]m^{(4)}[/tex] ) (([tex]n^{(-4)[/tex])[tex])^{(3))}[/tex]/ ((mn[tex])^{(2)}[/tex]), we will use the power rules of exponents.

First, we will apply the power rule to the numerator:

((-4)[tex])^{3}[/tex])([tex]m^{(4*3)}[/tex])([tex]n^{(4*3)}[/tex]) = (-64)([tex]m^{(12)}[/tex])([tex]n^{(12)}[/tex])

Next, we will apply the power rule to the denominator:

([tex]m^{(2)}[/tex])([tex]n^{(2)[/tex]) = [tex]m^{(2)}[/tex][tex]n^{(2)[/tex]

Now we can simplify the expression by canceling out the common terms in the numerator and denominator:

((-64)([tex]m^{12}[/tex])([tex]n^{12}[/tex])/([tex]m^{(2)}[/tex][tex]n^{(2)}[/tex])

= (-64)([tex]m^{12-2}[/tex])([tex]n^{12-2}[/tex])

= (-64[tex]m^{(10)}[/tex])/([tex]n^{(14)}[/tex])

Finally, we can write the final expression in simplified form:

(-64[tex]m^{(10)}[/tex])/([tex]n^{(14)}[/tex]).

Therefore, the simplified expression is (-64[tex]m^{(10)}[/tex])/([tex]n^{(14)}[/tex]).

f(x) can be factored into f(x) = 2(x + 5)(x + 3/2)(x - 3)(x - 5/2).

To find the real zeroes of f(x) = 2x^(4) + 17x^(3) + 35x^(2) - 9x - 45 using synthetic division, the Rational Root Theorem, and the Remainder Theorem, we need to follow these steps:

1. Using the Rational Root Theorem, we can find the possible rational roots of f(x) by taking the factors of the constant term (-45) and dividing them by the factors of the leading coefficient (2). The possible rational roots are:

±1, ±3, ±5, ±9, ±15, ±45, ±1/2, ±3/2, ±5/2, ±9/2, ±15/2, and ±45/2.

2. Next, we will use synthetic division to test these possible roots and find the real zeroes of f(x). We will start with the smallest possible root, -45/2, and divide f(x) by (x + 45/2) using synthetic division. The result is a polynomial of one degree less than f(x).

3. We will then use the Remainder Theorem to check if the remainder of the synthetic division is 0. If the remainder is 0, then -45/2 is a real zero of f(x) and we can use the Factor Theorem to factor f(x) into (x + 45/2)(2x^(3) - 8x^(2) - 80x + 90).

4. We will repeat steps 2 and 3 with the remaining possible rational roots until we find all the real zeroes of f(x).

5. Once we have found all the real zeroes of f(x), we can use the Factor Theorem to factor f(x) into the product of linear factors and a constant. The real zeroes of f(x) are -5, -3/2, 3, and 5/2.

Therefore, f(x) can be factored into f(x) = 2(x + 5)(x + 3/2)(x - 3)(x - 5/2).

The eigenvalues of matrix A are 11 and -1, and the corresponding eigenvectors are [1, -3, 0] and [1, 0, 0].

Eigenvalues and eigenvectors are important concepts in linear algebra. The eigenvalues of a matrix are the values that satisfy the equation Ax = λx, where A is the matrix, x is the eigenvector, and λ is the eigenvalue. The eigenvectors are the corresponding vectors that satisfy this equation.

To find the eigenvalues and eigenvectors of the matrix A=​2−15​013​00−3​​, we need to follow these steps:

1. Find the characteristic equation of the matrix A by subtracting λ from the diagonal elements and taking the determinant:
|A-λI| = |2-λ -1 5| = (2-λ)(-3-λ) - (-1)(5) = 0
|0 1 3|
|0 0 -3-λ|

2. Solve the characteristic equation to find the eigenvalues:
(2-λ)(-3-λ) - (-1)(5) = 0
-6 + 3λ + 2λ - λ² + 5 = 0
λ² - 5λ - 11 = 0
(λ - 11)(λ + 1) = 0
The eigenvalues are λ = 11 and λ = -1.

3. Find the eigenvectors by substituting the eigenvalues back into the equation Ax = λx and solving for x:
For λ = 11:
(2-11)x₁ - x₂ + 5x₃ = 0
x₂ + 3x₃ = 0
-3x₃ = 0
x = [1, -3, 0]
For λ = -1:
(2+1)x₁ - x₂ + 5x₃ = 0
x₂ + 3x₃ = 0
3x₃ = 0
x = [1, 0, 0]

The line L(t) = (2 - 4t, 3 – 2t, -5 – 4t) is neither parallel nor perpendicular to any of the given planes.

The line L(t) = (2 - 4t, 3 – 2t, -5 – 4t) can be written in parametric form as: x = 2 - 4t, y = 3 - 2t, and z = -5 - 4t. The

direction vector of the line is (-4, -2, -4).

To determine if the line is parallel or perpendicular to a given plane, we can take the dot product of the direction vector of the line and the normal vector of the plane. If the dot product is zero, the line is parallel to the plane. If the dot product is nonzero, the line is neither parallel nor perpendicular to the plane.

For the plane 6x + 3y + 6z = -39, the normal vector is (6, 3, 6). The dot product of the direction vector of the line and the normal vector of the plane is (-4)(6) + (-2)(3) + (-4)(6) = -42. Since the dot product is nonzero, the line is neither parallel nor perpendicular to the plane.

For the plane 8x + 24y - 20z = -8, the normal vector is (8, 24, -20). The dot product of the direction vector of the line and the normal vector of the plane is (-4)(8) + (-2)(24) + (-4)(-20) = 8. Since the dot product is nonzero, the line is neither parallel nor perpendicular to the plane.

For the plane 8x + 4y + 8z = 48, the normal vector is (8, 4, 8). The dot product of the direction vector of the line and the normal vector of the plane is (-4)(8) + (-2)(4) + (-4)(8) = -56. Since the dot product is nonzero, the line is neither parallel nor perpendicular to the plane.

For the plane 52 5y + 3z = -17, the normal vector is (0, 52, 3). The dot product of the direction vector of the line and the normal vector of the plane is (-4)(0) + (-2)(52) + (-4)(3) = -112. Since the dot product is nonzero, the line is neither parallel nor perpendicular to the plane.

Therefore, the line L(t) = (2 - 4t, 3 – 2t, -5 – 4t) is neither parallel nor perpendicular to any of the given planes.

Step-by-step explanation:

Let x be the total value of the estate.

According to the problem, the youngest child received 1.25 million and the share of each child is half of the remainder of the estate after the previous child has received their share.

So, the fourth child received 1.25 million, which is half of what the third child received. Therefore, the third child received 2.5 million.

Similarly, the second child received 2 times what the third child received, which is 5 million.

Finally, the first child received 2 times what the second child received, which is 10 million.

Adding up all the shares, we get:

1st child: 10 million

2nd child: 5 million

3rd child: 2.5 million
