There are 52 weeks in a year.
Using 50 for the number of weeks in a year is a(n) round.
Rounding is a process which we approximate the known number by just scaling it up or down.
In rounding the numbers less than 5 are scaled to one number less than the given integer and numbers such as 5 or above than 5 are scaled a number greater than the given number .
For example if there were 55 or more than weeks in a year we can say there are approximately 60 weeks in a year.
But there are 52 weeks so we <u><em>round</em></u> it to 50 weeks as 2 is less than 5.

Step-by-step explanation:
if you multiply 323 by 12 you get 2,876. Hope this helps!
It’s the 3rd one because the perpendicular slope of -1/2 would be 2/1 or just 2.
-- Subtract 17 from each side --- b/3 = 31 --- Multiply each side by 3 --- b = 93 . Note that you don't 'move' things from one side to the other. You simply do the same thing to both sides.
Answer:
0.01260
Step-by-step explanation:
Data:
probability of population with cancer (positive) = 0.21
probability of population with cancer (negative) = 0.79
probability of population with cancer absent (positive) = 0.06
probability of population with cancer absent (negative) = 0.94
probility for positive test = P( cancer (positive)) × P ( cancer absent (positive)
=
