The answer to this equation is 40.
To name 3 decimals between .55 and .56 just add another number to .55 For instance, .551 and .552 and
.553 are Three decimals between .55 and .56. If we start off with .55 we will not get to .56 untill .559 flips.
So
.550
.551
.552
.553
.554
.555
.556
.557
.558
.559
.56
Answer:
No
No
Each business major student is more likely to be selected than each political science student. Stratified Sampling was used.
Step-by-step explanation:
It is not a random sample nor a simple random sampling because each business major student is more likely to be selected than each political science student. In order for this to be a simple random sampling process, she would have to select 200 out of the full 440 students (260+180). The process applied was stratified sampling.
Is there like a picture or something?
Use pythagorean theorem:
sin^2 + cos^2 = 1
(-1/3)^2 + cos^2 = 1
1/9 + cos^2 = 1
cos^2 = 8/9
cos = +- sqrt(8)/sqrt(9) = +- 2sqrt(2)/3
Determine whether cos is positive or negative by looking at which quadrant the angle is in.
pi < theta < 3pi/2 ---> this is 3rd quadrant where x or cos is negative
Therefore cos(theta) = -2sqrt(2)/3
