Looking at z table you can find the probability = 0.8643.

Describe Probability?

The probability of an occurrence is a number used in science to describe how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more likely it is that the event will take place. A certain occurrence has a chance of 1, while an impossible event has a probability of 0. The odds of two complementing events A and B happening, either A happens or B happens, sum up to 1.

Probability that bulb will last at most 610 hours is same as bulb 1-probability that bulb will last more than 610 hours. Any way we can find the probability.

Pr <= 610 hours

Using Z statistic,

610-580/(900)^1/2 = 33/30 = 1.10

So we have z value = 1.10

Now looking at z table you can find the probability,

= 0.8643

Therefore , the solution of the given problem of expression comes out to be the simplified expression is (x + 2) / (x - 5)(x - 1).

There is a requirement for mathematical operations as addition, multiplication, and division. When combined, they produce the following: A mathematical operator, some data, and an equation A statement of fact contains values, parameters, and mathematical operations including additions, subtractions, multiplications, and divisions. It is possible to contrast and compare various sentences and words.

Here,

First, let's factor all the quadratics in the expression:

x^2 + 4x + 4 = (x + 2)^2

x^2 - 4 = (x + 2)(x - 2)

x^2 - x - 6 = (x - 3)(x + 2)

x^2 - 5x + 6 = (x - 2)(x - 3)

Now, we can rewrite the expression as:

[(x + 2)^2 / (x + 2)(x - 2)] * [(x - 2)(x - 3) / (x - 3)(x + 2)] * [(x + 2)(x - 3) / (x - 2)(x - 3)] * [(x - 2)(x - 3) / (x - 5)(x - 1)]

Notice that the (x + 2)(x - 3) terms cancel out in the numerator and denominator of the second and third fractions, respectively. Also, (x - 2)(x - 3) cancels out in the numerator and denominator of the third and fourth fractions, respectively.

Simplifying these terms, we are left with:

= [(x + 2) / (x - 2)] * [(x - 2) / (x - 5)(x - 1)]

= (x + 2) / (x - 5)(x - 1)

Therefore, the simplified expression is (x + 2) / (x - 5)(x - 1).

The polynomial f(x) of degree 4 that has the following zeros 3 (multiplicity 2), -2, 0 is f(x) = (x-3)^2 * (x+2) * (x-0).

To find the polynomial f(x), we can use the fact that the zeros of a polynomial are the values of x that make the polynomial equal to zero. In other words, if a polynomial f(x) has zeros at x=a, x=b, and x=c, then f(x) = (x-a) * (x-b) * (x-c).

In this case, we have zeros at x=3 (with multiplicity 2), x=-2, and x=0. This means that our polynomial will have factors of (x-3)^2, (x+2), and (x-0).

Multiplying these factors together gives us the polynomial f(x) = (x-3)^2 * (x+2) * (x-0), which simplifies to f(x) = (x^2 - 6x + 9) * (x+2) * x. Expanding this expression gives us the polynomial f(x) = x^4 - 4x^3 - 3x^2 + 12x.

Therefore, the polynomial f(x) of degree 4 that has the following zeros 3 (multiplicity 2), -2, 0 is f(x) = x^4 - 4x^3 - 3x^2 + 12x.

The function g(x) = 4∛(x+2) - 5 is a transformation of the cube root parent function f(x) = ∛x. The transformation involves a vertical stretch by a factor of 4, a horizontal shift to the left by 2 units, and a vertical shift downwards by 5 units.

The cube root parent function f(x) = ∛x has a single x-intercept at the origin (0,0) and is symmetric about the origin. It has a gradual increase as x moves from negative to positive values.

In contrast, the function g(x) = 4∛(x+2) - 5 has a vertical stretch by a factor of 4, making the graph steeper than the parent function. The horizontal shift to the left by 2 units moves the x-intercept to (-2,0). The vertical shift downwards by 5 units moves the entire graph downward, so the new y-intercept is at (0,-5).

Overall, the function g(x) has been vertically stretched, horizontally shifted to the left, and vertically shifted downward from the parent function f(x).

On January 31st, the money invested would have amounted to $10,737,418.

What is meant by investment?

An asset or object acquired with the intention of creating income or recognition is referred to as an investment. The purchase of products that are not consumed right away but will be utilised to create wealth down the road is referred to as an investment in an economic outlook. An investment in finance is a financial asset that is purchased with the expectation that it will either continue to generate income or be sold at a profit at a later date.

Given,

 A penny is invested on January 1.

It doubles each day.

We should find the amount on January 31.

First day = 1

Second day = 2

Third day = 4

Fourth day = 8

So basically if it is the xth day of January, then the amount on that day is 2ˣ⁻¹

Therefore on the January 31st, the money invested would have amounted to

The skier's velocity changes during the race due to the force of gravity, making turns on the course, and the conditions of the snow and terrain.

The skier's velocity changes during the race in several ways. Firstly, the skier starts at a slower velocity and gradually accelerates as they move down the slope. This is due to the force of gravity pulling them downwards, which increases their speed.

Secondly, the skier's velocity changes as they make turns on the course. When making a turn, the skier's velocity decreases as they have to slow down in order to make the turn. Once they have completed the turn, their velocity increases again as they accelerate down the slope.

Lastly, the skier's velocity also changes due to the conditions of the snow and the terrain. For example, if the snow is packed and icy, the skier's velocity will be faster than if the snow is soft and powdery. Similarly, if the terrain is steep, the skier's velocity will be faster than if the terrain is flat.

The value of the angle ∠EDC is 25 degrees for the triangle ABC.

According to the exterior angle theorem, an external angle's measure is equal to the sum of its remote interior angles' two opposite measures. Let's review a few fundamental facts concerning triangle angles: Three of a triangle's interior angles always add up to 180 degrees. This theorem is applied to all six of the exterior angles of the object. In order to make a linear pair of angles, an outer angle must be complementary to the neighbouring interior angle.

Given that, ∠B = ∠C and ∠BAD = 50 degrees.

Now, AE = AD hence, ∠ADE = ∠AED

Let ∠ADE = ∠AED = y.

From triangle ADC we have:

∠ADC = y + z

y + z = 50 + ∠B (exterior angles)

∠B = y + z - 50

Now, ∠B = ∠C thus,

∠C = y + z - 50

In triangle EDC we have:

∠E = x + y (exterior angles)

Also,

∠E + ∠D + ∠C = 180 (sum of interior angles of a triangle)

(x + y) + z + (y + z - 50) = 180

x + 2y + 2z = 230.........(1)

In triangle ADE,

x + 2y = 180

Substituting the values in 1 we have:

180 + 2z = 230

z = 25

Hence, the value of the angle ∠EDC is 25 degrees for the triangle ABC.

Gram (originally grams; [1] SI unit symbol g) is a mass unit in the International System of Units (SI), equal to one thousandth of a kilogram.

Originally defined from 1795 as "the absolute mass of a volume of pure water equal to one hundredth of a cubic meter [1 cm3] and at the melting point of ice", [2] the defining temperature (~ 0 °C) ) was later changed to

°C, which is the maximum density of water to temperature.

At the end of the 19th century, however, an attempt was made to make the basic unit the kilogram and a unit derived from the gram. In 1960, the new International System of Units defined the gram as one thousandth of a kilogram (ie, a gram is 1 × 10–3 kg). As of 2019, the International Bureau of Weights and Measures defines the kilogram as a fixed numerical value of Planck's constant (h) of 6.62607015×10−3
