Answer: incomplete question

Complete question: identify the sampling technique used.

The financial aid office at a nearby university publishes data about the type and amount of aid offered annually by collecting information from every 25th student to apply for financial aid this semester.

Answer: Systematic Sampling

Step-by-step explanation:

Systematic sampling:is easier to do than other sampling techniques. In systematic sampling, a list of elements are "counted off". That is, every nth element is taken. This is similar to lining everyone up and numbering off "4,5,6,7; 4,5,6,7; etc". When done numbering, all people numbered 4 would be used.

Find the sale price to the nearest cent .. $40 sweater; 33%discount​
fiasKO [112]

Answer:

$26.80

Step-by-step explanation:

(I don't know exactly how other people were taught to do percentages, but this is how I was taught and I find it the easiest for me.)

You are going to subtract your percentage number by 100.

100 - 33 = 67

This will give you your multiplier so you can then get your answer but you have to turn it into a decimal.

0.67 x 40 = 26.80

Which of the following is the solution to the system of linear equations<br> x=2y + 5 x/3-y=4/3
Alex73 [517]

Answer:

(7, 1)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

x = 2y + 5

x/3 - y = 4/3

<u>Step 2: Solve for </u><em><u>y</u></em>

  1. Substitute:                              (2y + 5)/3 - y = 4/3
  2. Multiply 3 on both sides:       2y + 5 - 3y = 4
  3. Combine like terms:               -y + 5 = 4
  4. Isolate <em>y</em> term:                         -y = -1
  5. Isolate <em>y</em>:                                  y = 1

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define:                    x = 2y + 5
  2. Substitute:              x = 2(1) + 5
  3. Multiply:                  x = 2 + 5
  4. Add:                        x = 7

And we have our final answer!
