There are 60 minutes in 1 hour
and 186 divided by 60 = 3 remainder 6
which means you have 3 hours and 6 minutes
that will get you the mixed fraction of
3 6/60 which can be simplified to
3 1/10
Answer:
The expected number of tests necessary for the entire group of 304 people is 180.0325
Step-by-step explanation:
Probability of person being positive = p = 0.04
Probability of person being negative = q = 1-0.04=0.96
Number of people in each group = 19
We will use binomial over here
Probability of no test positive :
P( at least one tests positive) = 1-P( no one tests positive)= 1-0.460419201958= 0.539580798042
Expected number of tests for each group = 1(0.460419201958)+20(0.539580798042) = 11.2520351628
Number of groups =
Expected number of tests necessary for the entire group of 304 people:
=
=
=180.0325
Hence The expected number of tests necessary for the entire group of 304 people is 180.0325
Description about easy geometry is given below
Step-by-step explanation:
1.The basic geometric objects that create shapes like : points, lines, line segments, rays, and planes. A point is represented by a dot and shows a location in space.
2.Geometry is easier and it was easier to study for. Algebra is more focused on equations while the things covered in Geometry really just have to do with finding the length of shapes and the measure of angles.
3.In two dimensions there are 3 geometries:
- Euclidean,
- spherical, and
- hyperbolic.
4.A point in geometry is a location. ... A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points.
Using rounding I would change 198 to 200 and 727 to 730.
200 + 730 = 930. Some would change the 727 to 700 but I see no need to do that. My answer will be closer using 200+730.
You can also get the exact answer like this - when you raise 198 to 200, you raised it by 2 so to compensate, take 2 away from the other number and 727 becomes 725
I can do 200 + 725 = 925 in my head and that happens to be the exact answer.
