Answer: (B) Systematic
Step-by-step explanation:
(A) Random : In this researcher randomly selects individual from population to make sample.
(B) Systematic : It is a kind of random sampling method where researcher decide the starting point to select individual , then follow a systematic pattern to select them.
(C) Stratified : It is a kind of random sampling method where researcher divides the population into groups ( on the basis of characteristics) called as strata , then selects individuals from each strata.
(D) Cluster : It is a kind of random sampling method where researcher divides the population into groups known as clusters , then randomly selects clusters to include in sample.
(E) Simple random : It is a kind of random sampling method where researcher randomly selects individual from population to make sample.
Since , a random number is generated to determine a starting position in the list and then every tenth attendee is placed in the sample.
That means sponsors follow as systematic pattern.
Therefore , the methods was used to select the probability sample : (B) Systematic

Answer:
(x, y) = (5, -8)
Step-by-step explanation:
The value of y is found by evaluating the equation for x=5.
y = 7 -3(5) = 7 -15 = -8
For x = 5, y = -8. As an ordered pair, this is (x, y) = (5, -8).
10% = 480$ / 10
= 48$
20% = 48$ * 2
= 96$
480$ - 96$ = 384$
Answer:
#1). 6 , 18 , 54
#2). 5/3 , 14 / 9 , 41/27
#3). 1.5 , 2.5 , 2.5
Step-by-step explanation:
#1).
g(x) = 3x
g(2) = 3 . 2 = 6
g²(2) = 3 . 3 . 2 = 18
g³(2) = 3 . 3 . 3 . 2 = 54
#2).
g(x) = 1/3 x + 1
g(2) = 2/3 + 1 = 5/3
g²(2) = g(5/3) = 5/9 + 1 = 14/9
g³(2) = g(14/9) = 14/27 + 1 = 41/27
#3).
g(x) = -1 ║x - 2 ║ + 3
g(0.5) = -1 (1.5) + 3 = 1.5
g²(0.5) = g(1.5) = -1(0.5) + 3 = 2.5
g³(0.5) = g(2.5) = -1(0.5) + 3 = 2.5
