A company wants to test clear deck sealants for weather resistance. Three brands of sealants will be tested using 60 pieces of decking wood. The company wants to create treatment groups of 20 pieces of wood each, and decide to randomize using slips of paper. Select all the approaches that would result in comparable treatment groups. The numbers 1, 2, and 3 are each written on 20 slips of paper, and the slips are placed in a hat and shaken well. The top piece of wood from a stack is selected and a slip of paper is drawn from the hat. That piece of wood is assigned to the group number on the slip. The slip of paper is returned to the hat. This continues until all pieces of wood have been assigned to a group. The numbers 1, 2, and 3 are written on three slips of paper, put into a hat, and shaken well. A slip is drawn and the first 20 pieces of wood on the stack are assigned to the group number on the slip. Another slip is drawn and the next 20 pieces of wood are assigned to that group. The remaining pieces of wood are assigned to the remaining group. Each piece of decking wood is assigned a number from 1 to 60. The numbers 1–60 are written on slips of paper and placed in a hat and shaken well. Twenty slips are drawn, shaking the hat after each slip of paper is drawn, and the pieces of wood corresponding to those numbers are placed in group 1. Twenty more slips are drawn in the same way, and the pieces of wood corresponding to those numbers are placed in group 2. The pieces of wood corresponding to the numbers on the remaining slips are placed in group 3. The numbers 1, 2, and 3 are each written on 20 slips of paper (20 for each number) and the slips are placed in a hat and shaken well. The top piece of wood from a stack is selected, and a slip of paper is drawn from the hat. That piece of wood is assigned to the group number on the slip. The slip of paper is not returned to the hat. This continues until all pieces of wood have been assigned to a group.

What is the percent change from 80 to 20? I’m confused

Answers

Answer:

75% decrease

Step-by-step explanation:

To calculate the percentage increase:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number

Then:  divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

If your answer is a negative number, then this is a percentage decrease.

To calculate percentage decrease:

First: work out the difference (decrease) between the two numbers you are comparing.

Decrease = Original Number - New Number

Then: divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100

If your answer is a negative number, then this is a percentage increase.

The measures of two angles in a triangle are 33 and 102 degrees

Answers

Answer:

The third angle is 45

SO all the angles inside of a triangle added up is 180

We have two sides

33+102=135

180-135=45

SO third angle is 45

Answer:

The third angle is 45 degrees

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

33+102 + x = 180

135+x =180

x = 180-35

x =45

The third angle is 45 degrees

Solve x and y 3x-4y=18,9x-2y=12

Answers

Answer:

3x-4y=18

1xy=18

xy=18 ans

Answer:

X=2/5

Y=-21/5

Step-by-step explanation:

solve your system by substitution.

3x−4y=18;9x−2y=12

Step: Solve3x−4y=18for x:

3x−4y=18

3x−4y+4y=18+4y(Add 4y to both sides)

3x=4y+18

3x/3=4y+18/3

(Divide both sides by 3)

x=4/3y+6

Step: Substitute 4/3y+6 for x in 9x −2y=12:

9(4/3y+6)−2y=12

10y+54=12(Simplify both sides of the equation)

10y+54+−54=12+−54(Add -54 to both sides)

10y=−42

10y/10=-42/10 .   (Divide both sides by 10)

y=-21/5

Step: Substitute

21/5 fory in x= 4/3y+6

x= 4/3y (-21/5) +6

  X=2/5 (Simplify both sides of the equation)

           Answer:

          X=2/5

Use the graph to find f(3).

f(3)=

Answers

Answer:

f(3) = -2

General Formulas and Concepts:

Algebra I

Reading a Cartesian Graph Function Notation

Step-by-step explanation:

f(3) is simply asking for the y-value when x = 3. According to the graph, when x = 3, y = -2.

Therefore, f(3) = -2

The function f(x) is a cubic function and the zeros of f(x) are -6, -3 and 1. The
y-intercept of f(x) is 90. Write the equation of the cubic polynomial in standard
form.

Answers

Answer:

[tex]P(x)=-5x^3-40x^2-45x+90[/tex]

Step-by-step explanation:

Equation of a Polynomial

Given the roots x1, x2, and x3 of a cubic polynomial, the equation can be written as:

[tex]P(x)=a(x-x1)(x-x2)(x-x3)[/tex]

Where a is the leading coefficient.

We know the three roots of the polynomial -6, -3, and 1, thus:

[tex]P(x)=a(x+6)(x+3)(x-1)[/tex]

Since the y-intercept of the polynomial is y=90 when x=0:

90=a(0+6)(0+3)(0-1)

90=a(6)(3)(-1)=-18a

Thus

a = 90/(-18) = -5

The polynomial is:

[tex]P(x)=-5(x+6)(x+3)(x-1)[/tex]

We must write it in standard form, so we have to multiply all of the factors as follows:

[tex]P(x)=-5(x^2+6x+3x+18)(x-1)[/tex]

[tex]P(x)=-5(x^2+9x+18)(x-1)[/tex]

[tex]P(x)=-5(x^3-x^2+9x^2-9x+18x-18)[/tex]

[tex]P(x)=-5(x^3+8x^2+9x-18)[/tex]

[tex]\boxed{P(x)=-5x^3-40x^2-45x+90}[/tex]

Abby is trying to pay off her debt. She owes $422 to her bank. In may she paid $76, but had to borrow an additional $135. In June she paid $45 and borrowed $110. The bank also charged her $58 in interest. How much did she owe at the end of June.

Do this quickly

Answers

Answer:

604

Step-by-step explanation:

Hi! Your answer to this problem..

Step by Step Explanation: Subtract 422 with 76, add 135, subtract 45, add 110, and lastly add 58.

Subtract 422 with 76, 422-76=366.

Add 366 with 135, answer will be 501.

Subtract 501 with 45 since she paid $45. 501-45=456.

Add 456 with 110 and that would be 566.

For the last step add 58 to find the answer and you would get 624.

Final Result: 624.
