Answer:

340

Step-by-step explanation:

There are a total of 100+100 = 200 people surveyed over the 2 days.

There were 38+42 = 80 people who prefer mysteries.  This means 80/200 prefer mysteries.

This tells us that out of 850 customers,

80/200(850) = 68000/200 = 340 will probably purchase mystery books.

Please help. if a line falls on the points (6,8) and (1,5) what is it’s slope?
Ksenya-84 [330]

Answer:

m= 3/5.

Step-by-step explanation:

The general equation of the line is:

(y - y0) = m ( x - x0), where "m" represents the slope is: (y1 - y0) / (x1 - x0).

From the statement we know that (x1, y1) = (6, 8) and (x0, y0) = (1,5)

Then the slope is:

m= (y1 - y0) / (x1 - x0) = (8 - 5)/(6 - 1) = 3/5.

The slope is 3/5
