A researcher needs to assign 10 subjects, numbered 0 to 9, to one of two treatment groups: A and B. Use the table of random digits, starting with the first row and first column, to carry out the random assignment. Select the correct random assignment using the table.

A: 0, 7, 5, 8, 1 B: 3, 4, 7, 2, 8
A: 0, 2, 4, 6, 8 B: 1, 3, 5, 7, 9
A: 0, 3, 6, 5, 8 B: 2, 9, 1, 7, 4
A: 0, 7, 5, 8, 1 B: 3, 4, 2, 6, 9

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
