Answer:
a) 103, b) No
Step-by-step explanation:
a) We need to multiply the probability by the amount of the sample to get:
200 × 51.6% = 103.2, rounded down to 103
b) As we have selected the people randomly, we have no control over the type of people we are given - this is theoretical and the estimate is not definite - all of the sample could have murdered by firearm or even none (even though it is highly unlikely).
Answer:The distance between the endpoints (11,−4) and (−12,−4) are 23 units
Step-by-step explanation:
Sin2(x) +cos(x)=1
from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}
Nobody wants to do these because, I don't know why.
