The false statement about completely random designs is this:  c.) The additional variables affect different control groups differently.

The false statement about completely random designs is that additional variables affect different control groups differently. It is however true that in completely random esigns, the subjects are randomly assigned to treatments and any number of treatments may be addressed.

Also, the goal of this type of design is to reduce the effects of confounding variables. So, the correct option number that describes the false statement is C.

Answer:

  (a) 1 inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.

__

The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.

The question asks for an explanation of the slope, not its function in the equation. That is why we have chosen the first answer.

Answer: inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The expression that results in rational number are A+B, A+D, B+D and A+A

Rational number are numbers that include the square root of prime numbers

Given the following parameters

We need to determine the operation that will result in a rational number

A + B = √3 + 2√3

A+B = 3√3

A+D = √3 + 4
B + D = 2√3 + 4

A + A = √3 +√3 = 2√3

Hence the expression that results in rational number are A+B, A+D, B+D and A+A

Answer:

60

Step-by-step explanation:

Divide the number of questions answered correctly by his percentage

51 / 85 = 0.6

Now multiply that answer by 100 to see how many questions are on the quiz

0.6 x 100 = 60

Check your work by dividing that number by the number he answered correctly

51 / 60 = 0.85

For algebraic division use KCF method.

K - Keep the first fraction

C- Change division to multiplicatin

F -Flip the second fraction.

3) Indenty used: (a -b)² =a² -2ab + b²

Where a = m and b =2

4) Identity used: (a +b)² = a² + 2ab +b²

Where a = w and b = 1

5) Identity used: a² - b² = (a +b)*(a -b)

Where a = z and b = 2

Explanation:

Use the formula C = pi*d

We're multiplying 3.14 by the diameter 100 to get 314, which is the approximate distance around the circle (aka perimeter). The value is approximate because pi = 3.14 is approximate.

To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator, or LCD. Write each expression using the LCD.

Adding or subtracting rational expressions is remarkably similar to adding and subtracting fractions, since a rational expression is a fraction.

The operations are the same.

When adding or subtracting fractions with unlike denominators, we multiply the denominator of one fraction times the denominator of the other fraction, and then alter the numerators.

The process with rational expressions is the same.

So the first step is to make sure both rational expressions have the same denominator.

Answer:

Mr. Hildebrant planned to spend $95 in the gift shop.

Step-by-step explanation:

We want to find 80% of $? equals $76.

We can write an equation to help us solve for x, the money that Mr. Hildebrant planned to spend in the gift shop.

Divide both sides of the equation by .80.

Mr. Hildebrant planned to spend $95 in the gift shop.

Answer:

D) -22 < 25

Step-by-step explanation:

If the number is 47 units to the right, then the number will be larger than -22, because negative values get larger the closer they are to zero.

47 units right from -22 is the same as: -22 + 47, which equals 25.

So, we can conclude that -22 < 25 is the inequality.
