If a pollster wishes to estimate the number of left-handed scientists. The sample that is needed in order to be 95% confident that the sample proportion will not differ from the true proportion by more than 4% is: 176.71.

Using this formula to find the sample

n =Z²π (1-π) ÷ e²

Where:

n =sample size =?

Z =  Z -score for 95% confidence level =1.960

π = Population proportion = 0.08

e = Margin of error = 0.04

Let plug in the formula

n = 1.96² × 0.08 × (1 - 0.08) ÷ 0.04²

n =  3.8416× 0.08 × 0.92 ÷ 0.0016

According to the solution we have come to find that, The smallest of the four consecutive integers is 18.

Consecutive integers are integers that follow each other in order, such that the difference between any two consecutive integers is always 1.

Let's call the smallest integer x. Since there are four consecutive integers, we can express the other three as x+1, x+2, and x+3.

We know that the sum of these four integers is 78, so we can write an equation:

x + (x+1) + (x+2) + (x+3) = 78

Simplifying this equation:

4x + 6 = 78

Subtracting 6 from both sides:

4x = 72

Dividing both sides by 4:

x = 18

Therefore, the smallest of the four consecutive integers is 18.

Step-by-step explanation:

The perfect square that starts with x² + 6x is:

(x + 3)² - 9 + 6x

or

(x + 3)² + 6x - 9

The missing constant term in the perfect square, we need to complete the square for the quadratic expression x² + 6x.

We can do this by adding and subtracting the square of half of the coefficient of x (which is 6/2 = 3) within the parentheses, like this:

x² + 6x + (3)² - (3)²

The expression inside the parentheses is now a perfect square:

(x + 3)² - 9

This is now in the form of a perfect square plus or minus a constant.

The missing constant term is -9.

the quadratic formula x2 + 6x, we must complete the perfect square by adding the constant component that is missing.

In the brackets, we may achieve this by adding and subtracting the square of the x-coefficient's half (6/2 = 3).

x² + 6x + (3)² - (3)²

The phrase enclosed in brackets is now squarely formed:

(x + 3)² - 9

A perfect square plus or minus a constant now represents this.

-9 is the omitted constant term.

To calculate the energy of the resulting explosion when a 10,000 kg UFO made of antimatter crashes with a 40,000 kg plane made of matter, we can use Einstein's famous equation, E=mc², which relates energy (E) to mass (m) and the speed of light (c).

In this case, we'll need to calculate the total mass of matter and antimatter involved in the collision and then use the equation to find the energy released. The equation E=mc² states that energy is equal to the mass multiplied by the square of the speed of light (c). In this scenario, we have a collision between a UFO made of antimatter and a plane made of matter. Antimatter and matter annihilate each other when they come into contact, resulting in a release of energy.

To calculate the energy of the resulting explosion, we need to determine the total mass involved in the collision. The total mass can be calculated by adding the masses of the UFO and the plane together. In this case, the UFO has a mass of 10,000 kg and the plane has a mass of 40,000 kg, so the total mass is 50,000 kg.

Next, we can use the equation E=mc² to calculate the energy. The speed of light (c) is a constant value, approximately 3 x 10^8 meters per second. Plugging in the values, we have E = (50,000 kg) x (3 x 10^8 m/s)². Simplifying the equation, we have E = 50,000 kg x 9 x 10^16 m²/s².Multiplying the numbers, we get E = 4.5 x 10^21 joules. Therefore, the energy of the resulting explosion when the UFO and plane collide is approximately 4.5 x 10^21 joules.

To show that $(e,de)$ is totally bounded, we need to show that for any \($\epsilon > 0$\), there exist finitely many points\($x_1, x_2, \ldots, x_n$\)in $e$ such that $e \subseteq \bigcup_{i=1}^n B_{\epsilon}^{de}(x_i)$, where \($B_{\epsilon}^{de}(x_i)\)$ denotes the open ball of radius $\epsilon$ centered at $x_i$ with respect to the metric $de$.

Since $(x,d)$ is totally bounded, for any $\epsilon>0$, there exist finitely many points $y_1, y_2, \ldots, y_m$ in $x$ such that $x \subseteq \bigcup_{i=1}^m B_{\epsilon/2}^d(y_i)$. Since $e \subseteq x$, we have $e \subseteq \bigcup_{i=1}^m B_{\epsilon/2}^d(y_i)$.

Now, for each\($i=1,2,\ldots,m$, let $x_i$\) be any point in\($e \cap B_{\epsilon/2}^d(y_i)$\). Then, we have $e \subseteq \bigcup_{i=1}^m B_{\epsilon/2}^d(y_i) \subseteq \bigcup_{i=1}^m B_{\epsilon}^{de}(x_i)$. Therefore, $(e,de)$ is totally bounded.

The area of a rectangle can be found by multiplying the length and width. We have the area and the width, so we can use algebra to solve for the length. Then we can use the formulas for perimeter to find the perimeter of the rectangle.

Let L be the length of the rectangle. Then we have:

L × 9 = 162

Divide both sides by 9 to solve for L:L = 162 ÷ 9 = 18

Now we can use the formulas for perimeter to find the perimeter of the rectangle.

The formulas for the perimeter of a rectangle is:P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

Substituting L = 18 and W = 9, we get:P = 2(18) + 2(9) = 36 + 18 = 54Therefore, the perimeter of the rectangle field is 54 m.Conclusion:The width of a rectangle field is given to be 9 m. The area of the rectangle is 162 m². We can use algebra to solve for the length of the rectangle by using the formula for the area of a rectangle. Once we have the length, we can use the formulas for perimeter to find the perimeter of the rectangle. The perimeter of the rectangle field is 54 m.

The perimeter of the field is 54 m.

The area of a rectangle can be found by multiplying the length and width. We have the area and the width, so we can use algebra to solve for the length. Then we can use the formulas for perimeter to find the perimeter of the rectangle.

Given:

A rectangle field has an area of 162 m².

The width of the field is 9 m.

The formula for area of rectangle = length of rectangle * width of rectangle.

Let L be the length of the rectangle.

Then put the value of length and width in area's equation.

A = L × W

162 = L × 9

L = 18.

The formula for the perimeter of a rectangle is:

P = 2 (L + W).

Substituting L = 18 and W = 9, we get:

P = 2(18) + 2(9) = 36 + 18 = 54

Therefore, the perimeter of the rectangle field is 54 m.

Answer:

a15 = -163840

(Note: check if you really have to calculate the 15th term and not, say the 5th term in which case a5 = 80)

Step-by-step explanation:

We have the sequence 5, -10, 20, -40,

We, see that for each term, the previous term is multiplied by -2,

so,

a1 = 5,

a2 = 5(-2) = -10

a3 = (-10)(-2) = 20

a4 = (20)(-2) = -40

and so on,

We see that this is a geometric sequence with -2 being the common ratio and 5 being a1,

so,using,

\(a_{n} = a_1(r)^{n-1}\\a_n=5(-2)^{n-1}\\for \ n = 15,\\a_{15} = 5(-2)^{15}\\a_{15} = 5(-32768)\\a_{15} = -163840\)

hence a15 = -163840

The factored form of the function is  (x - 5)(x + 5)(x - 2)²

The given function is f(x) = x⁴ - 4x³ - 21x² + 100x - 100

Since x = 5, then use synthetic division to find the factored polynomial so we can find another root:

5    |    1    -4    -21    100    -100

    |    ↓    5      5     -80      100

          1    1     -16     20       0 ← remainder is zero so (x - 5) is a factor

Use the factored polynomial to find another root:

-5   |    1     1     -16    20

    |    ↓   -5     20   -20  

          1   -4      4      0 ← remainder is zero so (x + 5) is a factor

Now use the perfect square formula on the factored polynomial:

If the discriminant is less than 0, the equation has no real solution. Looking at the graph of a quadratic equation, if the parabola does not cross or intersect the x-axis, then the equation has no real solution. And no real solution does not mean that there is no solution, but that the solutions are not real numbers. Some equations have exactly one solution. In these equations, there is only one value for the variable that makes the equation true. You can tell that an equation has one solution if you solve the equation and get a variable equal to a number.

By identifying the vertex of the function, we conclude that it is increasing for:

x > -1

Here we have an absolute value function:

f(x) = |x + 1| - 3

This absolute value function has a positive coefficient, which means that the function opens upwards, so it looks like a regular "V" letter.

The function is increasing when, reading from left to right, we see that the line goes upwards. And for functions like this, this happens for values of x larger than the vertex x-value.

For:

f(x) = |x + 1| - 3

The vertex is at (-1, -3)

Then the function is increasing for x > -1
