For a, b, and c being independent random variables uniformly distributed over (0,1), the joint cumulative distribution function of a, b, and c is given by:

F(a,b,c) = abc

For the probability that all of the roots of the equation Ax2 + Bx + C = 0 are real, we can use the quadratic formula to solve for the roots:

x = [-B +/- sqrt(B^2 - 4AC)]/2A

To ensure that these roots are real, we must make sure that the discriminant B^2 - 4AC is greater than or equal to 0. The probability that this is the case is given by the integral of the joint cumulative distribution function over the range 0 <= B^2 - 4AC >= 0, which evaluates to 1/8.

Therefore, the probability that all of the roots of the equation Ax2 + Bx + C = 0 are real is 1/8.

Steady Snow   [tex]{}[/tex]            (11, 16]         h(d) = 3 + (1/2)·d   Interval of Increase

A function is a rule that defines how input and output variables are related, such that an input has exactly one output.

The starting amount of snow, h₁ = 15 inches

The coordinate of the point on the graph is; (h₁, d₁) = (0, 15)

The rate at which the snow will melt = 1.5 inches per days

Number of days over which the snow melts = 8 days

The equation for the first part of the graph is therefore;

h(d) = 15 - 1.5·d

The height of the snow after the first 8 days is therefore;

h₂, h(8) = 15 - 1.5 × 8 = 3

The height of the snow after the first 8 days is 3 inches

The point on the graph is; (h₂, d₂) = (8, 3)

The height of the snow remains steady in the next three days, therefore;

h₂ = h₃ = 3 inches

The point on the graph is; (h₃, d₃) = (11, 3)

The rate at which the snow accumulates from day 11 = (1/2) an inch per day

Number of days over which the snow will accumulate = 5 days

The equation is; h(d) = 3 + (1/2)·d

Therefore; h₄ = 3 + (1/2) × 5 = 5.5

The height of the snow after 5 more days is 5.5 inches

The point on the graph is therefore; (h₄, d₄) = (16, 5.5)

The points on the graph are therefore;

(0, 15), (8, 3), (11, 3), and (16, 5.5)

The integral of the current I(t) over the interval [a,b] represents the change in the charge Q from time t=a to t=b.

The current in an electrical circuit is defined as the rate at which charge is flowing through a conductor. The equation that represents the current is I(t) = dQ(t)/dt, where Q(t) is the charge at time t and dQ(t)/dt is the derivative of Q(t) with respect to time, representing the rate of change of charge.

The integral of I(t) with respect to time between the limits a and b, i.e. ∫I(t)dt between the limits a and b, represents the change in the charge from time t = a to time t = b. This is because the definite integral of a rate of change gives the total change in the quantity being measured, in this case, the charge.

So, [tex]\int\limits^a_b {|(t)} \, dt = Q(b) -Q(a)[/tex], which represents the change in the charge from time t = a to time t = b.

Answer:

So the perimeter of the rectangle is 33y + 1 feet.

Step-by-step explanation:

Let's call the width of the rectangle "w" and the length "l". From the given information, we have:

w = 7y - 9.5

l = 9.5y + 10

The perimeter of a rectangle is equal to the sum of the lengths of all four sides, so we can find the perimeter by adding up the values of w and l:

P = 2w + 2l

= 2(7y - 9.5) + 2(9.5y + 10)

= 14y - 19 + 19y + 20

= 33y + 1

So the perimeter of the rectangle is 33y + 1 feet.

The number of elements in B is 26.

Given that the number of elements in A union B is 40, the number of elements in A is 20 and the number of elements in A intersect B is 6, we can use the following formula to calculate the number of elements in B:

n(B) = n(A ∪ B) - n(A) + n(A ∩ B)

Substituting the given values, we get:

n(B) = 40 - 20 + 6

Therefore, n(B) = 26

The above formula can be broken down into the following steps:

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

This formula states that the number of elements in A union B is equal to the sum of the number of elements in A and B minus the number of elements in A intersect B.

Therefore, if we know the number of elements in A union B and the number of elements in A intersect B, we can calculate the number of elements in B by subtracting the number of elements in A from the number of elements in A union B and then adding the number of elements in A intersect B.

In this case, given that the number of elements in A union B is 40, the number of elements in A is 20, and the number of elements in A intersect B is 6, we can calculate the number of elements in B by subtracting the number of elements in A (20) from the number of elements in A union B (40) and then adding the number of elements in A intersect B (6).

This yields n(B) = 40 - 20 + 6 = 26.

The value of x from the given figure is 155°.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the given figure,

By angle sum property,

125°+a=180°

a=55°

Now, angles at a point on straight line is

55°+b°+60°=180°

a) The total volume of the prism is given as follows: 162 cubic units.

b) The scale factor to contract the prism is given as follows: 1/3.

c) The volume of the dilated prism is given as follows: 6 cubic units.

The volume of a rectangular prism, with dimensions length, width and height, is given by the multiplication of these dimensions, as follows:

Volume = length x width x height.

The dimensions for this problem are given as follows:

Length = 3, Width = 6, Height = 9.

Hence the volume is of:

V = 3 x 6 x 9

V = 162 cubic units.

The attributed scale factor is given as follows:

1/3.

As it is a contraction, the scale factor must be less than 1.

Hence the fraction that the volume of the dilated prism will represent is given as follows:

The value of c that minimizes MSE is given by the equation above:

c = sum(y * x) / sum(x²)

To determine the value of c that minimizes the mean squared error (MSE), we must first find the derivative of MSE with respect to c and set it equal to zero. This will give us the critical points, which can then be tested to determine if they correspond to a minimum or maximum.

        dJ(c) / dc = 2 * sum((y - (c * x)) * (-x)) / n

       c = sum(y * x) / sum(x²)

        d² J(c) / dc² = -2 * sum(x²) / n
