Which of the settings does not allow use of a matched pairs t procedure? You interview a sample of 15 instructors and another 15 students and ask each how many hours per week homework assignments require. You interview 40 students in the introductory statistics course at the beginning of the semester and ask how many hours per week homework assignments require. You interview both the instructor and one of the students in each of 20 introductory statistics classes and ask each how many hours per week homework assignments require. None of the other options are correct.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

what is the question

a sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°c. if the system is at dynamic equilibrium, which of these statements is true?  

answer: number of steps anna and todd walk 150 and 250 respectively.

step-by-step explanation:

since we have given that

for every 3 steps of anna's steps , todd made 5 steps .

so, there will be ratio i.e.

so, the number of steps anna walk = 3x

the number of steps todd walk = 5x

according to question,

so,

number of steps anna walk is given by

number of   steps todd walk is given by
