You are on an academic committee tasked to evaluate state employment math test questions. The following question has come to the attention of the committee:
"Each of the four digits 3, 4, 5, and 8 is placed in one of the boxes to form a fraction. The numerator and the denominator are two-digit whole numbers. What is the smallest value of all the common fractions that can be formed? Express your answer as a reduced fraction."

There are 4 boxes arranged in a square with 2 boxes side-by-side directly on top of the other 2 boxes. There is a horizontal line representing a fraction bar separating the top 2 boxes from the bottom 2 boxes.
Some committee members contend this is not a valid question.
Solve the problem. (If there is no solution, enter NO SOLUTION.)

Explain the solution to prove (or disprove) the question's validity.
The question is valid because to make the fraction as small as possible, you make the numerator as small as possible and make the denominator as large as possible.The question is valid because to make the fraction as small as possible, you make the numerator as large as possible and make the denominator as small as possible.

Given the normal distribution, the following can be illustrated:

1. The number of people who have an IQ between 70 and 130 is 1024.

2. The number of people who have an IQ between 85 and 115 is 1024.

The number of people who have an IQ over 145 is 3.

1. The The number of people who have an IQ between 70 and 130 will be:

z(115) = (130-100)/15 = 2

z(85) = (70-100)/15 = -2

P(-2< z < 2) = 0.6827

The number of 1500 that have IQ between 70 and 130 will be:

= 0.6827 × 1500

= 1024

2. The number of people who have an IQ between 85 and 115 will be:

z(115) = (115-100)/15 = 1

z(85) = (85-100)/15 = -1

We need to consult Z-table to find P value with this Z value

P(85< x < 115) = P(-1< z < 1) = 0.6827

Number of people of 1500 that have IQ between 85 and 115:

= 0.6827 × 1500

= 1024

3. The number of people who have IQ over 145?

Z(>145)

=( 145-100)/15

Answer:

d ≈ 11.40

Step-by-step explanation:

K: (-4, -6); L: (5, 1)

    (x₁, y₁)     (x₂, y₂)

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(5 - (-4))² + (1 - (-6))²

d = √(5 + 4)² + (1 + 6)²

d = √(9)² + (7)²

d = √81 + 49

d = √130 ≈ 11.40

a) An equation to model the problem of determining the birth year when the average life expectancy will be 71 years is y = 55 + 0.2x.

b) From the equation above, from 1980 or in the 80th birth, the average life expectancy will be 71 years.

The average life expectancy refers to the average time in years that a person is expected to live after birth.

The average life expectancy has been a statistical tool for understanding a person's lifespan on earth based on some demographics.

An equation is a mathematical statement that equates two or more variables, numbers, or values or regards them as equivalent or equal.

For this situation, we can use the formed equation to predict a person's life expectancy average in the future, given the current years and increasing rate of life expectancy.

Life expectancy in 1900 = 55 years

Life expectancy increase for each birth year after 1900 = 0.2

Life expectancy = y

Year = x

y = 55 + 0.2x ... Equation

71 = 55 + 0.2x

0.2x = 16

x = 16/0.2

= 80 birth year

1980 = (1900 + 80)

The statement is true. This is an example of Factorization being correct as it takes the factors of the quadratic equation set them equal to 0 and then calculates the value of x.

In the given question, an example of factorization is taken for the equation x²+4x-21 which is factorized using the Middle-Term split rule. We have to find out if the example is conducted correctly.

Factorization is the rule to factorize an equation such that its factors if multiplied together form the equation itself.

We will verify the factorization, for equation x²+4x-21

=> x² + 4x - 21

=> x² + 7x -3x -21

=> x(x + 7) -3(x + 7)

=> (x + 7)(x - 3) = 0

=> x = -7, x = 3

The non-real solutions of the polynomial expression are x = (1 + 2√-5)/3 and x = (1 - 2√-5)/3

The equation of the polynomial expression is given as:

3x5 + 25x4 + 26x3 – 82x2 + 76x = 48

Rewrite the equation as

3x^5 + 25x^4 + 26x^3 – 82x^2 + 76x - 48 = 0

The points on the graph are given as

(-6, 0), (-5, 500), (-2.5, -450), (0, - 50), (1, 0), (2, 400).

Write out the x-intercepts

(-6, 0) and (1, 0)

This means that

Real solution = -6

Real solution = 1

Rewrite the above as

x = -6 and x = 1

So, we have

x + 6 = 0 and x - 1 = 0

Multiply

(x + 6)(x - 1) = 0

The next step is to divide the polynomial equation 3x^5 + 25x^4 + 26x^3 – 82x^2 + 76x - 48 = 0 by (x + 6)(x - 1) = 0

This is represented as

3x^5 + 25x^4 + 26x^3 – 82x^2 + 76x - 48/(x + 6)(x - 1)

Using a graphing calculator, we have

3x^5 + 25x^4 + 26x^3 – 82x^2 + 76x - 48/(x + 6)(x - 1) = 3x^3 + 10x^2 - 6x + 8

So, we have

3x^3 + 10x^2 - 6x + 8

Factorize

(x + 4)(3x^2 - 2x + 2)

Next, we determine the solution of the quadratic expression 3x^2 - 2x + 2 using a quadratic formula

So, we have

x = (-b ± √(b² - 4ac))/2a

This gives

x = (2 ± √((-2)² - 4 * 3 * 2))/2 * 3

So, we have

x = (2 ± √-20)/6

This gives

x = (2 ± 4√-5)/6

Divide

x = (1 ± 2√-5)/3

Split

x = (1 + 2√-5)/3 and x = (1 - 2√-5)/3

So, the conclusion is that

Using the polynomial expression, the non-real solutions are x = (1 + 2√-5)/3 and x = (1 - 2√-5)/3

It is found that the displacement between t= 0  and t = 1 second is of 0.536 m.

The equation of motion is given by:

x(t) = 4 sin(πt + π/2)

The displacement between t= 0  and t = 1 second is given by:

d = x(1) - x(0)

Hence,

position of the object when t = 1

x(1) = 4sin(π(1) + 1 (π/2))

= 4 sin (π + π/2)

= 4 sin (3π/2)

= 4 x √3/2

= 2√3

= 3.464

position of the object when t = 0

x(0) = 4sin(π(0) + (π/2))

= 4 sin (0 + π/2)

= 4 x 1

= 4

Then,

d = x(1) - x(0)

= 4 - 3.464

= 0.536(approx)

Therefore, the displacement of the object between t = 0 and t = 1 is 0.536.

If a street that is 270 ft long is covered in snow. City workers are using a snowplow to clear the street. The diameter of the tire is: 3.2 meters.

First step is to determine the circumference of the tire

Circumference of the tire =  (270 m / 27)

Circumference of the tire = 10 meters

Second step is to make use of  3.14 for π to determine the diameter of the tire using this formula

Diameter of the tire = Circumference of the tire /  π

Let plug in the formula

Diameter of the tire = 10 / 3.14

Diameter of the tire = 3.18 meters

Diameter of the tire = 3.2 meters (Approximately)
