Among the following, the population mean u = (upper confidence limit) + (lower confidence limit) is not derived from the confidence interval.

A confidence interval is defined as the range of values that we observe in our samples and for which  we expect to find the value that accurately reflects the population.

In frequentist statistic, a confidence interval is a range of estimates for an unknown parameter.    

To find a confidence level for a data set by taking half of the size of the confidence interval, multiplying it by the square root of the sample size and then dividing by the sample standard deviation.

Confidence level refers to the percentage of probability,or certainty, that the confidence interval would contain the true population parameter when you draw a random sample many times. The most common confidence levels are 90%, 95% and 99%.

C.) $50

D.) 1.5%

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The percentage equation goes thus:

Interest earned = principal * rate * time

A)

Principal: $100 Interest rate: 5% Time in years: 3 Interest earned

Interest earned = $100 * 0.05 * 3

Interest earned = $15

B.)

Principa;" $500 Interest rate: 4% Time in years: interest earned: $20

Interest earned = principal * rate * time

20 = 500 * 0.04 * time

20 = 20 * time

Time = 20 / 20 = 1

Time = 1 year

C.)

Principal: Interest rate:10% Time in years: 7 Interest earned:$35

Interest earned = principal * rate * time

$35 = principal * 0.1 * 7

$35 = principal * 0.7

Principal = $35 / 0.7

Principal = $50

D.)

Principal: $200 Interest rate: Time in years:2 Interest earned: $6

Interest earned = principal * rate * time

Answer:

[tex]x=\dfrac{2+\sqrt{2}\: i}{2}, \quad x=\dfrac{2-\sqrt{2}\: i}{2}[/tex]

Step-by-step explanation:

Given quadratic equation:

[tex]2x^2-4x+3=0[/tex]

When completing the square for a quadratic equation in the form ax²+bx+c=0, first move the constant to the right side of the equation:

[tex]2x^2-4x=-3[/tex]

Divide both sides of the equation by the coefficient of x²:

[tex]x^2-2x=-\dfrac{3}{2}[/tex]

Add the square of half the coefficient of the term in x to both sides to form a perfect square trinomial on the left side:

[tex]x^2-2x+\left(\dfrac{-2}{2}\right)^2=-\dfrac{3}{2}+\left(\dfrac{-2}{2}\right)^2[/tex]

Simplify:

[tex]x^2-2x+1=-\dfrac{3}{2}+1[/tex]

[tex]x^2-2x+1=-\dfrac{1}{2}[/tex]

Factor the perfect square trinomial on the left side:

[tex](x-1)^2=-\dfrac{1}{2}[/tex]

Square root both sides:

[tex]\sqrt{(x-1)^2}=\sqrt{-\dfrac{1}{2}}[/tex]

[tex]x-1=\pm\sqrt{-\dfrac{1}{2}}[/tex]

Simplify:

[tex]x-1=\pm\sqrt{\dfrac{1}{2} \cdot -1}[/tex]

[tex]x-1=\pm\sqrt{\dfrac{1}{2}} \sqrt{-1}[/tex]

[tex]x-1=\pm\dfrac{1}{\sqrt{2}} i[/tex]

[tex]x-1=\pm\dfrac{\sqrt{2}}{2} i[/tex]

Add 1 to both sides:

[tex]x=1\pm\dfrac{\sqrt{2}}{2} i[/tex]

[tex]x=\dfrac{2}{2}\pm\dfrac{\sqrt{2}}{2} i[/tex]

[tex]x=\dfrac{2\pm\sqrt{2}\: i}{2}[/tex]

Therefore, the solutions of the given quadratic equation using the method of completing the square are:

The additive counterpart of given expressions are (2a+3b), -2a+2(-b+c), and -3(a+2b)+2c=0.

When two numbers may be added together or multiplied, regardless of the order in which they are entered, the result is said to be commutative. There are different formulas available for the conversion of multiplicative expressions to their additive counterparts.

a) The first expression is a²b³. This expression is written as aabbb. This is of the form ab and its corresponding additive counterpart is of the form a+b.

Then, a+a+b+b+b=2a+3b.

b) The second expression is a⁻²(b⁻¹c)². This expression is of the form a⁻¹ and its corresponding additive counterpart is of the form -a.

Then,

[tex]\begin{aligned}a^{-2}(b^{-1}c)^2&=a^{-1}a^{-1}(b^{-1}c)(b^{-1}c)\\&=-a-a-b+c-b+c\\&=-2a+2(-b+c)\end{aligned}[/tex]

c) The third expression is (ab²)⁻³c²=e. This expression is first expanded as, (ab²)⁻¹(ab²)⁻¹(ab²)⁻¹c²=e. Using property, (xy)⁻¹=y⁻¹x⁻¹.

Then,

[tex]\begin{aligned}((b^2)^{-1}a^{-1})((b^2)^{-1}a^{-1})((b^2)^{-1}a^{-1})c^2&=e\\(b^{-2}a^{-1})(b^{-2}a^{-1})(b^{-2}a^{-1})c^2&=e\end{aligned}[/tex]

Also, the additive identity to e is zero. And, aⁿ=na.

Then,

(-2b-a)+(-2b-a)+(-2b-a)+2c=0

Simplifying we get,

-3(a+2b)+2c=0.

The number of children take greek and hebrew = 2

In this question, we have been given that in a class of 30 children, 20 take latin, 14 take greek, and 10 take hebrew.

So, n(s) = 30

Let set a: children taking Latin language

n(a) = 20

set b: children taking Greek language

n(b) = 14

set C: children taking Hebrew language

n(c) = 10

no child takes all three languages

⇒ n(a ∩ b ∩ c) = 0

And eight children take no language

⇒ n(S) -  n(a ∪ b ∪ c) = 8

So, n(a ∪ b ∪ c) = 8

This means, 22 children taking languages.

Of those 22 kids, 14 take Greek and 10 take Hebrew.

14+10 = 24

This means, at least 2 children must taking Greek and Hebrew.

Since no child takes all three languages, the children taking Greek and Hebrew can't be taking Latin. Since 20 of the 22 kids are taking Latin, that means at most 2 are taking Greek and Hebrew.

To find the distance between the high school and the stadium, we need to use the distance formula. The distance formula is given by the following equation:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) is the coordinates of the starting point, and (x2, y2) is the coordinates of the ending point.

In this case, the starting point is the high school, which is located at the coordinates (2, 5), and the ending point is the stadium in Columbus, which is located at the coordinates (8, 13). Plugging these values into the distance formula, we get:

d = sqrt((8 - 2)^2 + (13 - 5)^2)

d = sqrt(6^2 + 8^2)

d = sqrt(36 + 64)

d = sqrt(100)

d = 10

Therefore, the distance between the high school and the stadium is 10 units. Since 1 unit is equal to 8.6 miles, the distance between the high school and the stadium is 86 miles.

It's worth noting that the rest stop is located halfway between the high school and the stadium. This means that the distance from the high school to the rest stop is 86/2 = 43 miles, and the distance from the rest stop to the stadium is also 43 miles. This can be verified by using the distance formula to find the distance between the rest stop and the high school, and then between the rest stop and the stadium.

The value of z after solving the equation z³ = 8 is 2.

The result of a number (x) being multiplied three times is referred to as the cube of that number. The phrase "cube root" in mathematics means "the number that needs to be multiplied three times in order to acquire the original number." Let's now examine the cube root formula, in which y is equal to the cube root of x. ∛x = y. Any integer can be represented as the cube root by the radical sign ∛, which has a little 3 written on the top left of the sign. Writing 1/3 as a number's exponent is another method to represent a cube root.

The given equation

z³ = 8

The number 8 can be written as

8 = 2 × 2 × 2

So,

z³ = 2³

z = 2
