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.
The answer choice which represents a solution to the system of equations is; (–2, 10).
<h3>Which answer choice is a solution to the systems of equations?</h3>
The system of equations as given in the task content is;
-6x - (2/5)y = 8
(1/2)x +3y = 29
Hence, by making x subject in equation 1 and substitution; we have;
x = (-0.4y -8)/6
Hence; (0.4y -8)/12 + 3y = 29.
(0.4y -8) + 36y = 348
35.6y = 356
y = 10
and x = (-0.4(10) -8)/6 = -2.

A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one. Proof:
Suppose 1 box is bought of each (x=1),original will cos10 & the cheaper $7
b) Each time he buys a cheap brand he save $3 ($10-$7), on 5 cheap boxes, he would save $3 x 5 boxes = $15
Answer:
Step-by-step explanation:
K=3x+8
Hope this helped mark me as brainiest
14:2 , 21:3 , 28:4 . Multiply both sides by any number.
