Answer:
x,y = 13/3, -10/3
Step-by-step explanation:
8x+8y=8
8x+2y=28 Subtract eq1 by eq 2
6y=-20
y=-20/6 y = -10/3
8x - 80/3=8
8x=34 2/3
x=4 1/3
x=13/3
Hope this helps plz hit the crown :D
<span>1/2-(5/4) = x+1/4 // - x+1/4
1/2-x-(5/4)-(1/4) = 0
1/2-x-5/4-1/4 = 0
-x-1 = 0 // + 1
-x = 1 // * -1
x = -1
x = -1

<span>π </span>* 6 = 18.8495559215 / 4 = 4.71238898038
It'll will be 24% because it's like a fraction so three cranberry in a bag of 8 so 3/8 8x3 will be 24 then just add the percents
Given
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
To find:
Which of these types of sampling is used: random, stratified, systematic, cluster, convenience?
Explanation:
It is given that,
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
That implies,
Since Stratified random sampling is a method of sampling that involves dividing a population into smaller groups–called strata.
Then, the random sampling used is Stratified Random Sampling.
