Answer:
The coordinates of P' are (4.8,-4.8).
Step-by-step explanation:
The rule of dilation represent the dilation with scale factor 2.4 and center at origin.
If the scale factor of the dilation is k and the center is (0,0), then
Since the scale factor is 2.4, therefore
From the given figure it is noticed that the coordinates of P are (2,-2). The coordinates of P' are
Therefore the coordinates of P' are (4.8,-4.8).
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
