suppose life expectancy for freezers has an unknown distribution with mean 16 years and standard deviation 2 years. a sample of size n

Answer:

10.37

Step-by-step explanation:

3 in the thousandths place is lower than 5 therefore you have to turn the thousandths into a 0 and don't change the forenumber

After evaluating f(x) = 3x - 5, the answer is f(x-2) = 3x - 11

What do you mean by functions?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). Expressions of well-known functions can be found in many frequently used mathematical formulas. A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

The set X is called the domain of the function and the set Y is called the codomain of the function.

Given function:

f(x) = 3x - 5

For f(x-2) substitute x as (x-2) in given function

f(x-2) = 3(x - 2) - 5 = 3x - 6 - 5 = 3x - 11

therefore, f(x-2) = 3x - 11

We know that,

Consider the Turing machine M, which computes the inverse of x for every positive inter. The result will also be x if the computation is done using both the integer x and its inverse.

This is because the result of adding a binary number 1 to 0 is always 1. The criterion is that the binary representation of x must not contain 0. In this case, a positive integer x is converted into binary representation.

Only x values with a binary representation of 1 will be accepted by the Turing machine. Even the Turing machine will accept inverse-of-x values with binary representations of 0.

The confidence interval for the average age of the population would be (18.8, 25.2).

What is the confidence interval?

In frequentist statistics, a confidence interval is a range of estimates for an unknown parameter. A confidence interval is computed at a designated confidence level; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used.

Given that,

Point estimate = sample mean = [tex]\bar x[/tex] =22

sample standard deviation = s = 6

sample size = n = 16

Degrees of freedom = df = n - 1 = 16 - 1 = 15

At 95% confidence level

[tex]\alpha[/tex] = 1 - 95%

[tex]\alpha[/tex] =1 - 0.95 =0.05

[tex]\alpha/2[/tex] = 0.025

[tex]t_{\alpha/2},df[/tex] = t 0.025 , 15 = 2.131

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the number be represented as A

Now , the value of A is calculated as

Five subtracted from the product of 6 and a number is at most -25

So , the inequality equation will be

And , substituting the values in the equation , we get

The dimensions of the radius is 4/3[tex]\sqrt{2}[/tex] and that of height is 8/3.

Let r be the radius of the cone,  be the radius of the sphere and h be the height of the cone.

Let's put DˆOB=x with limitations 0≤x≤π.

In the right-angled triangle DOB:

r=DB=Rsinx, OD=Rcosx, than

h=CD=OC+OD=R+Rcosx=R(1+cosx).

So the volume of the cone is:

V=1/3πr²h ⇒V=1/3π(Rsinx)²⋅R(1+cosx)

V=1/3πR³sin²x(1+cosx)

V'=1/3πR³⋅[2sinx⋅cosx⋅(1+cosx)+sin2x(−sinx)]

  =1/3πR³sinx[2cosx(1+cosx)−sin2x]

  =1/3πR³sinx(2cosx+2cos2x−sin2x)

  =1/3πR³sinx(2cosx+2cos2x−1+cos2x)

 =1/3πR³sinx(3cos2x+2cosx−1)

Now let's find the signum of the derivative, since sinx≥0 for every x in the limitations, then:

V'≥0⇒3cos²x+2cosx−1≥0

      ⇒Δ/4=(b/2)²−ac =1+3=4

cosx=(−b/2)±√Δ/4 / a

      =−1±2/3,

So:

cosx≤−1∨cosx≥1/3

The first one has only the solution:

x=π

the second:

−arccos(1/3)≤x≤arccos(1/3), but for the limitations:

0≤x≤arccos(1/3).

The function gros from zero to arccos(1/3), and then it decreases.

So x=arccos(1/3) is the maximum requested.

Let's find now r and h:

r=Rsinx

 =R√1−cos2x

 = 2√1−(1/3)²

 = 2√1−1/9

 =2√9−1/9

 =2√8/9

 =2⋅2√2/3

 =4/3√2

h=R(1+cosx)=2(1+1/3)

 =2(3+1/3)

=8/3.

Therefore the radius is 4/3√2 and the height is 8/3.

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Answer:

To answer these questions, we need to first calculate the total number of payments you have made over the past 3 years. We can do this by multiplying the number of payments per year (12) by the number of years (3). This gives us a total of 36 payments.

Next, we can use a financial calculator or spreadsheet program to solve for the remaining balance on your loan after making 36 payments of $327.51 each. In a financial calculator, we can enter the following values:

N: 36

I: 5.8

PV: -14000

PMT: 327.51

FV: 0

Solving for PV gives us a remaining balance of $4,819.56. Therefore, the answer to part A is $4,819.56.

To find your equity in the car, we can subtract the remaining balance on the loan from the value of the car. In this case, your equity would be $7,500.00 - $4,819.56 = $2,680.44. Therefore, the answer to part B is $2,680.44.

What is Diagonalizable matrix?

If there is an invertible matrix P and a diagonal matrix D such that

P^-1AP=D, or alternatively A=PDP^-1, then the square matrix A is said to be diagonalizable or non-defective in linear algebra.

If and only if the algebraic multiplicity of each of A's eigenvalues is equal to the geometric multiplicity of each eigenvalue, then A is diagonalizable. The fact that the geometric sum of the eigenvalues of A is n is an equivalent description.

The given statement is false.

If A is diagonalizable, then A had n distinct eigenvalues. It could have repeated eigenvalues as long as the basis of each eigenspace is equal to the multiplicity of that eigenvalue.
