Answer:

Use a factor tree. For example, 625 = 5 x 125 = 5 x 5 x 25 = 5 x 5 x 5 x 5. Because there are 4 fives, and we are looking for the square root, (5 x 5) (5 x 5) = 625. Therefore the square root of 625 is 25.

Event A and Event B being mutually exclusive means that they cannot occur simultaneously. On the other hand, Event A and Event C not being mutually exclusive means that they can occur together or overlap.

Mutually exclusive events refer to events that cannot happen at the same time. If Event A occurs, then Event B cannot occur, and vice versa. For example, if Event A represents "heads" in a coin toss, and Event B represents "tails," it is impossible for both events to happen simultaneously. Therefore, the occurrence of one event precludes the occurrence of the other.

Non-mutually exclusive events, as in the case of Event A and Event C, allow for the possibility of both events occurring together. For instance, if Event A represents "rain" and Event C represents "using an umbrella," it is possible for it to rain (Event A) and for someone to be using an umbrella (Event C) at the same time. In this case, the occurrence of Event A does not exclude the occurrence of Event C.

Understanding whether events are mutually exclusive or not is essential in probability theory, as it influences how probabilities are calculated. When events are mutually exclusive, the probability of either event occurring is simply the sum of their individual probabilities. However, when events are not mutually exclusive, the probability of both events occurring requires a different calculation, such as using conditional probabilities or the inclusion-exclusion principle.

In summary, Event A and Event B are mutually exclusive, meaning they cannot occur simultaneously, while Event A and Event C are not mutually exclusive, allowing for the possibility of both events occurring together.

The area of triangle EFG, to the nearest square inch, is approximately 1061 square inches.

To find the area of triangle EFG, we can use the formula:

\(Area = (1/2) \times base \times height\)

In this case, the base of the triangle is FG, and the height is the perpendicular distance from vertex E to side FG.

First, let's find the length of FG. We can use the law of cosines:

FG² = EF² + EG² - 2 * EF * EG * cos(∠F)

EF = 72 inches

EG = 34 inches

∠F = 21°

Plugging these values into the equation:

FG² = 72² + 34² - 2 * 72 * 34 * cos(21°)

Solving for FG, we get:

FG ≈ 83.02 inches

Next, we need to find the height. We can use the formula:

height = \(EF \times sin( \angle F)\)

Plugging in the values:

height = 72 * sin(21°)

height ≈ 25.52 inches

Now we can calculate the area:

\(Area = (1/2) \times FG \times height\\Area = (1/2)\times 83.02 \times 25.52\)

Area ≈ 1060.78 square inches

distribution of the total number of tumors produced in the whole population over a one-year period by this kind of radiation is 0, 1, 2, ..................104000.

let, x denote the total number of hits,

y denotes the number of hits by a particle in a year or an individual,

one per week ⇒ 52 per year

therefore, rate = 52 per year

since it is very rare to hit all individuals, we can use Poisson distribution.

therefore by using the formula p (x = x) = (e^(-rate) × rateˣ) ÷ x! ; x = 0, 1, 2, ............( 2000 × 52)

p (x = 2) = (e⁻⁵² × 52ˣ) ÷ x! ; x = 0, 1, 2, ............104000

now each hit has a harm of probability 10⁻⁵.

so p(total no. of tumors produced over a one year period)

= {e⁻⁵² × 52ˣ} ÷ x! × 10⁻⁵ ; x = 0, 1, 2, ............104000

therefore total no. of tumors = 2000 × (e⁻⁵² × \(52^{x.10^{-5} }\) ) ÷ x!  × xⁿ ; x = 0, 1, 2, ............104000

Assume that each of the 2000 individuals living near a nuclear power plant is exposed to particles of a certain kind of radiation at an average rate of one per week. Suppose that each hit by a particle is harmless with a probability of 1 - 10⁻⁵, and produces a tumor with a probability of 10⁻⁵. Find the approximate distribution of the total number of tumors produced in the whole population over a one-year period by this kind of radiation.

This value represents the present worth below which the probability is 0.5, indicating a negative present worth.

To estimate the probability that the present worth is negative using the NORM.INV function in Excel,

we need to calculate the present worth of the project and then determine the corresponding probability using the normal distribution.

The present worth of the project can be calculated by finding the sum of the present values of the annual receipts over the 10-year period, minus the initial investment. The present value of each annual receipt can be calculated by discounting it back to the present using the minimum attractive rate of return (MARR).

Using the given information, the present value of the initial investment is $10,000. The present value of each annual receipt is calculated by dividing the expected return of $1,800 by \((1+MARR)^t\),

where t is the year. We then sum up these present values for each year.

We can use the NORM.INV function in Excel to estimate the probability of a negative present worth. The function requires the probability value, mean, and standard deviation as inputs.

Since we have a mean and standard deviation for the present worth,

we can calculate the corresponding probability of a negative present worth using NORM.INV.

This value represents the present worth below which the probability is 0.5. By using the NORM.INV function,

we can estimate the probability that the present worth is negative based on the given data and assumptions.

For the curve, y = x⁸, 0≤ x ≤ 1

a) The area of the curve surface obtained by rotating the curve about the x-axis is equals to the \(A = \int_{a}^{b} 2π(x⁸)\sqrt(1+ 8x⁷)²dx .\)

b) The area of the surface obtained by rotating the curve about the y-axis is equals to the \(A = \int_{c}^{d} 2πx( \frac{ds}{dy})dy\).

We have, a curve equation, y = x⁸ ; 0≤x≤1.

a) We have to set up integral for area of the surface by the rotating about x -axis,

the arc of the curve y = f(x) from x = a to x = b is \(A = \int_{a}^{b} 2πyds

= \int_{a}^{b} 2πy(\frac{ds}{dx})dx \)

where \( \frac{ds}{dx}= \sqrt{(1 + \frac{dy} {dx})²}\)

Now, differentiating the curve equation, y = x⁸

=> dy/dx = 8x⁷

so, ds/dx = √(1 + 8x⁷)²

Therefore, Area of surface about rotating x-axis is \(A= \int_{a}^{b} 2π(x⁸)\sqrt(1+ 8x⁷)² dx.\)

b) Similarly, the area of the surface by the rotating about y -axis, of the arc of the curve x = f(y) from y = c to y = d is written as \(A = \int_{c}^{d} 2πx( \frac{ds}{dy})dy\).

Hence, we determined the integral for area of surface when rotating about x-axis and y-axis.

Answer:

the solution is (18, 3)

Step-by-step explanation:

Let's first eliminate x.  Multiply the second equation by 2, obtaining

2x = 6y + 18

Then add this result to the first equation 2y - 2x = -30:

2x = 6y + 18

2y - 2x = -30

--------------------  or

2x = 6y + 18

-2x = -30 - 2y

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

0 = 4y - 12, which yields y = 3.

Substitute 3 for  y in the second equation to obtain the value of x:

x = 3(3) + 9, or x = 18

Then the solution is (18, 3).

Note that we could do this faster by reducing 2y - 2x = -30 to y - x = -15

Then the second equation becomes x = 3(y) + 9, or

                                                              x = 3y + 9, with x = 18

Then 18 = 3y + 9, or 3y = 9, or y = 3 (as before)

To solve this problem, let us first find the probability that x < y when point (x, y) is randomly selected from inside the rectangle. Then, using the area of the rectangle, normalize the probability.

The probability that x < y is 1/8.

To find the probability that x < y when a point is randomly chosen from within the rectangle. Let A be the area of the region where x < y, and B be the area of the rectangle. Then, the probability that x < y is given by P(x < y) = A/B. To find A and B, let us first look at the line x = y, which passes through (0,0) and (1,1) and separates the rectangle into two regions: Region I: The area to the right of the line x = y, where x > y. Region II: The area to the left of the line x = y, where x < y. region xy plane Region I has area B - A, and Region II has area A. Hence, B - A + A = B, which implies A/B = A/(B - A) = 1/2. Therefore, we only need to find A.

Let C be the triangle with vertices (0,0), (1,0), and (1,1). This triangle has area 1/2. Since the rectangle has height 1, the line x = y intersects the rectangle at a height of 1/2, which means that A is the area of the trapezoid with vertices (1/2, 0), (1, 0), (1, 1), and (1/2, 1/2).trapezoid xy plane. To find the area of this trapezoid, we can split it into a rectangle and a right triangle, as shown below: split trapezoid xy plane. The rectangle has base 1/2 and height 1, so its area is 1/2. The triangle has base 1/2 and height 1/2, so its area is 1/8. Hence, the area of the trapezoid is 1/2 + 1/8 = 5/8. Therefore, the probability that x < y is P(x < y) = A/B = (5/8) / 4 = 1/8.

The derivative of (f ◦ g) with respect to u is h'(u) = [2, 2g(u), \(-3g(u)^2].\) To compute the derivatives of the given functions, we'll start with finding the Jacobian matrices for each function.

For the function f(u) = \((u, u^2, u^3)\), the Jacobian matrix Df is:

Df = [∂f₁/∂u, ∂f₂/∂u, ∂f₃/∂u]

  =\([1, 2u, 3u^2]\)

For the function g(x, y, z) = 2x + y − z, the Jacobian matrix Dg is:

Dg = [∂g/∂x, ∂g/∂y, ∂g/∂z]

  = [2, 1, -1]

Next, we'll compute the derivative of the composition function (f ◦ g) using the chain rule. Let h(u) = (f ◦ g)(u), then:

h'(u) = D(f ◦ g)/du = Df(g(u)) * Dg(u)

Substituting the values we have:

\(h'(u) = [1, 2g(u), 3g(u)^2] * [2, 1, -1]\)

    \(= [2, 2g(u), -3g(u)^2]\)

Therefore, the derivative of (f ◦ g) with respect to u is h'(u) = [2, 2g(u), \(-3g(u)^2].\)
