A university has 27 academic units ranging in size from 2 to 92 faculty members. A sample of 10 academic units were selected with probabilities proportional to size and with replacement, and within each sample academic unit an SRS of four members were selected. Note that academic unit 14 appears three times in the sample; each time it appears, a different subsample was collected.

Find the estimated total number of publications, along with its standard error.

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
