Cloud seeding simpson, alsen, and eden (technometrics 1975) report the results of trials in which clouds were seeded and the amount of rainfall recorded. the authors report on 26 seeded and 26 unseeded clouds in order of the amount of rainfall, largest amount first. here are two possible tests to study the question of whether cloud seeding works. paired t-test of m(1 - 2) mean of paired differences = -277.39615 t-statistic = -3.641 with 25 df p = 0.0012 2-sample t-test of m1 - m2 difference between means = -277.4 t-statistic = -1.998 with 33 df p = 0.0538 a) which of these tests is appropriate for these data? explain. b) using the test you selected, state your conclusion.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

c

step-by-step explanation:

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
