Answer:
A=3(π/2)-1 au
Step-by-step explanation:
we have according to the graph that
f(x)=3
g(x)=cos(x)
Knowing A=∫|f(x)-g(x)|dx, then
; where a=0 and b=π/2
A=(3x-sin(x)) evaluated 0 ≤ x ≤ π/2
A=(3(π/2)-sin(π/2))-(3.0-sin(0))
Answer:
Item (D)
Step-by-step explanation:
In the stratified random sample we would divide our population into homogeneous groups / strata and then we randomly select the individuals in each group / stratum.
In general, when comparing with the simple random sample, we realize that stratified random sampling has the advantage of increasing accuracy and decreasing variability.
In the question, we have two strata: female students and male students. On each one of the strata, a random sample of 25 names was made in the list.
