Answer:

58

Step-by-step explanation:

You would have to turn 7 1/4 into a whole fraction.

Do,

7 * 4 = 28

28 + 1 = 29

Your new fraction would be,

29/4

Now you have to make them equal denominators with 1/8.

Lets see,

Now multiply 4 * 2 is 8.

So multiply 29 times 2.

Which is 58.

Your new fraction is,

58/8

So therefore you would have 58 pieces.

In a random sample of 32 times loading Twisting Thunder and 36 times loading Spiral Wonder, the probability is 0.9574.

It's also known as the Gaussian Distribution. It is the most important continuous probability distribution in the world. Because the curve resembles a bell, it is also known as a bell curve.

The average time for riders to board the Twisting Thunder roller coaster is 49 seconds, with a standard deviation of 7.1 seconds.

The likelihood in a random sample of 32 is

z= (x-μ)/σ

z=(32-49)/7.1

z= -2.394

P(x32) =0.0083246 from the Z-Table

The average time to board the Spiral Wonder roller coaster is 44.8 seconds, with a standard deviation of 3.7 seconds.

In a random sample of 36, the probability is

z= (x-μ)/σ

z=(36-44.8)/3.7

z= -2.37838

P(x36) = 0.0086945 from the Z-Table

In a random sample of 32 times loading Twisting Thunder and 36 times loading Spiral Wonder, the probability is P(x32)/P(x36)=0.0083246/0.0086945 =0.9574.

The total number of transistors in the Titan is equal to 5.950 × 10²¹ transistors.

A supercomputer simply refers to one of the most powerful computers that is designed and developed for handling, evaluating, and solving very complicated problems, calculations, or tasks, better than ordinary desktop or laptop computers.

In order to determine the total number of transistors in the Titan, we would multiply the number of transistors in its central processing unit (CPU) by the number of transistor in its graphics processing unit (GPU) as follows:

Total number of transistors = 4.485 × 10¹⁰ × 1.3268 × 10¹¹

Total number of transistors = (4.485 × 1.3268) × (10¹⁰ × 10¹¹)

Total number of transistors = 5.950 × (10⁽¹⁰ ⁺ ¹¹⁾)

Total number of transistors = 5.950 × 10²¹ transistors.

The value of t in the equation can be express as follows:

[tex]t = \frac{V-7\pi r^{2} }{6\pi r}[/tex]

The subject of a formula is the variable that is being worked out. The subject of a formula is the variable which is expressed in terms of the other variables.

The variable to be worked out is t.

Therefore,

V = 6πrt + 7πr²

Therefore, let's make t the subject of the formula,

V = 6πrt + 7πr²

subtract 7πr² from both sides of the equation.

V = 6πrt + 7πr²

V - 7πr² = 6πrt + 7πr² -7πr²

V - 7πr² = 6πrt

divide both sides of the equation by 6πr

Hence,

[tex]\frac{V-7\pi r^{2} }{6\pi r}=t[/tex]

The value of test statistic t is -2.39 and P-value is P(t₈< -2.39).

The mean and the standard deviation can be calculated from the below formulae:

Sample mean (X)= (∑xi)/n

Sample standard deviation (s)= √(∑xi- X)²/(n-1)

where, n is sample size = 9

xi= elements in sample

On calculation we get X as,

X = (3.5+6.5+6.5+5.5+19.5+7+12.5+20+10.5)/9 = 10.17

s = √(∑xi- X)²/(n-1)

= √(44.49+13.47+13.47+21.81+87.05+10.05+5.43+96.63+0.11)/8

= √36.57 = 6.04

t would represent the static, it is given by the formula,

t = (X-μ₀)/(s/√n)

where μ₀ = 15 from the data (the value we want to test)

t = (X-μ₀)/(s/√n) = (10.17-15)/(6.04/√9) = -2.39

In scientific notation, the amount of paper used weekly by the Pittsburgh paper is approximately 5.0 x 10⁷ times more than the amount used by the Newville paper.

Scientific notation is a shorthand or approximated way to write large or small numbers.

Scientists use scientific notations to eliminate the many zeros in a number so that the number is written in a standard form.

In scientific notation, a positive integer is multiplied by another integer (positive or negative) in the power of ten.

The best way to compute the ratio of paper usage at the two newspapers is to rewrite the numbers in long form and convert the answer to scientific notation.

Location     Paper Used (square yards)

Newville     8.0 x 10³ = 8,000

Pittsburgh  4.0 x 10¹¹ = 400,000,000,000

The ratio of Pittsburgh to Newville = 8,000:400,000,000,000

= 1: 50,000,000

= 1: 5.0 x 10⁷

We can also divide 400,000,000,000 by 8,000 to get 50,000,000, which can then be written in standard form as 5.0 x 10⁷.

Thus, expressing the result in scientific notation, the Pittsburgh paper approximately uses 5.0 x 10⁷ more paper than the Newville paper.

Step-by-step explanation:

You want to know the number of roots of x^3+4x^2-9x-36.

The degree of the given polynomial is the highest exponent of x: 3. That is the number of roots the polynomial has.

There are 3 roots.

The number of sign changes among the coefficients tells you the number of positive real roots. The signs go from + to - one time, so there is one positive real root.

When the signs of odd-degree terms are switched, the signs become ...

  - + + -

There are two sign changes here, meaning that there may be 2 or 0 negative real roots. (If there are 0 real roots, the two roots are complex.)

You can see that successive pairs of terms have coefficients with the same ratio. That means you can factor this by grouping terms:

  x^3+4x^2-9x-36

  = (x^3+4x^2) -(9x+36)

  = x^2(x +4) -9(x +4)

  = (x^2 -9)(x +4)

  = (x -3)(x +3)(x +4) . . . . . roots -4, -3, and +3

Matrix A is invertible such that A⁻¹ = - A - 3I. This is solved using the Calely Hamilton Theorem.

This theorem says that every square matrix satisfies its own characteristic equation. In other words, the scalar polynomial

p(λ) = det(λI − σ) also holds for the stress polynomial p(σ).

It also states that The roots λ₁, λ₂........λₙ of a typical equation (aₙλₙ + aₙ₋₁ λⁿ⁻¹ + ...... a₁ λ + a₀)  will indicate the nature of the Matrix A. If either of the roots of the attributes equation is 0, the matrix's determinant becomes zero. As a result, the matrix is non-invertible.

Based on the above, we know that Matrix A fulfills the qualities below::

A²+3A + I = 0

Since every square matrix fulfills its own characteristic

λ₁ + λ₂ = -3

λ₁ x λ₂ = 1 ≠ 0

This is true for any order of a square matrix. That is:
λ₁ x λ₂ x λ₃ x........ x λₙ ≠ 0

Thus

|A| = λ₁ x λ₂ x λ₃ x........ x λₙ

|A| ≠ 0 → Invertibel Matrix

A² + 3A + I = 0
I = -A² - 3A
A⁻¹ x I = A⁻¹ (-A - 3A); hence

A⁻¹ = - A - 3I

What is equation straight line?

There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1).

The given equation y = -1/5 x + 4.

Step-by-step explanation:

Given function,

→ f(x) = (-16/1225)x² + (7/5)x + 1.5

Required function,

→ f(x) = f(0)

→ f(0) = (-16/1225)x² + (7/5)x + 1.5

Now the needed height is,

→ (-16/1225)x² + (7/5)x + 1.5

→ (-16/1225)(0)² + (7/5)(0) + 1.5

→ 0 + 0 + 1.5

→ 1.5 feet

Hence, the height is 1.5 feet.
