The mean has a value of 8 minutes and a standard deviation of 0.9736.

The sum of a set of numbers divided by the total number of numbers in the set is known as the arithmetic mean or arithmetic average in mathematics and statistics. The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including basic arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Here,

X= attention span of the 2 year old

μ=8

σ=8

m=1/8

X=exp(1/8)

An angle GHI measures 28° degrees.

What is the angle sum property of a triangle?

The triangle's inner angles can be added up to 180°, according to the triangle's "angle sum property."

For example, in a triangle, ABC, the sum of angles A, B, and C will be 180°.

Given, ∡G = 62°

∡I = 90° and ∡ H = ?

From the angle sum property of a triangle,

∡G + ∡ H + ∡I = 180°

or, 62° + ∡ H + 90° = 180°

or, ∡ H + 152° = 180°

or, ∡ H = 180° - 152° = 28°

or, Angle GHI = 28°

Hence, the required value of Angle GHI is 28°.

80.8% of the time, the average yearly snowfall across the 25 years that were randomly chosen will be greater than 72.8 inches.

As the question stated;

The z score is estimated as;

z = (x - μ)/σ

In which,

Mean μ =  70 inche

standard deviation σ = 10 inches.

n = 25

z = (72.8 - 70)/(10/√25)

z = 2.8/2

z = 1.40

Use z-score table to find the value;

P(x > 72.8 inches) = P(z > 1.40)

P(x > 72.8 inches) = 1 - P(z < 1.40)

P(x > 72.8 inches) = 1 - 0.9192

P(x > 72.8 inches) = 0.0808

Thus, 80.8% of the time, the average yearly snowfall across the 25 years that were randomly chosen will be greater than 72.8 inches.

It is proved that, for every positive integer n, there are n consecutive composite integers.

Given statement,

For every positive integer n, there are n consecutive composite integers.

Proof:

Assume that m is less than n and that both m and n are positive integers. When m is less than n,

n! = 1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n,

which is to say that m is a factor of n!

So,

m + n! = m + ( 1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n )

          = m ((1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n) / m + 1)

Since m is a multiple of n!, n!/m is still an integer. Since the integer m is bounded between 1 and n, it follows that any number you choose up to n can divide m + n!, making it composite until the nth integer.

However, since n! contains the nth integer, the nth integer is also composite, meaning you can choose any integer between 1 and n inclusively and it will be composite.

What is rectangle?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. It is also known as an equiangular quadrilateral for this reason.

                                          Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.

Let x = length of the side parallel to the river

     y = length of each of the other two sides

Then xy = 5,000, so y = 5,000/x

Minimize:  L = length of the fence

L = x + 2y

 = x + 10,000/x, where x > 0

L' = 1 - 10,000/x2 = (x2 - 10,000)/x2

L' = 0 when x = 100 or -100

Since x can't be negative, x must be 100.

When 0 < x < 100, L' < 0.  So, L is decreasing.

When x > 100, L' > 0.  So L is increasing.

Therefore, L has a relative and absolute minimum when x = 100 m

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of rainfall in 2 minutes = 75 mm

So , the amount of rainfall in 1 minute = amount of rainfall in 2 minutes / 2

The possible length of the region after solving the quadratic equation is either 170ft or 50ft.

What is a quadratic equation?

A quadratic equation in algebra is any equation that can be written in the simpler form where x stands for an unknown value and a, b, and c are known quantities. The assumption is that a > 0; an equation with a = 0 is thought to be degenerate because they become linear or even simpler.

Solution Explained:
Lets assume, length = x and width = y

So we know, the area and perimeter is supposed to be 8500 and 440 respectively

we form the equations,

1) 8500 = xy , and                       [Area = length*width]

2) 440 = 2(x + y)                           [ Perimeter = 2(length +width)]

   220 = x + y

So, x = 8500/y (from equation 1) and put the value of x in 2

220 = x + (8500/x)

After solving this we get the quadratic equation,

x^2 - 220x + 8500 = 0

Solving the equation, we get

x = 170 or, x = 50 which are the two possible lengths of the region.

William must make 1806 copies before his total cost is less than the photocopy store.

Let William made x copies from his home photocopier.

Now total cost of x copies = 0.12 x + 162.5

Total cost of x copies from the store = 0.21 x

Now his cost needs to be lower, so we form an inequality to solve this problem.

0.12x + 162.5 < 0.21x

or, 0.12x - 0.21x < -162.5

or, -0.09x < -162.5

or, x > 1805.56

Hence the minimum value of x will be 1806.

Therefore we can say that he needs to make at least 1806 copies.

I is higher. The more scatter around the regression line, the higher the uncertainty associated with the slope estimate, b1. If there is a lot of scatter, the estimated slope is less reliable than if there is very little scatter.

The uncertainty associated with the slope estimate, b1, is higher when there is a lot of scatter around the regression line. This is because the estimate of the slope is based on the data points, and when there is a lot of scatter, the data points are more spread out and the estimate of the slope is less reliable.

In regression analysis, the scatter of data points around the regression line is important in determining the uncertainty of the slope estimate. When there is a lot of scatter, the data points are more spread out and the estimate of the slope is less reliable.

For the derivation of the Navier-Stokes equations we consider a fluid element and the forces acting on it. At first we will consider only the motion of the fluid in x-direction. The motion of the fluid element is influenced by the pressure forces acting on the front and back surface of the cubic volume element.

    These pressure forces basically represent normal stresses and are therefore denoted in the following by the Greek symbol σ instead of p.
