A) mean = np
0.6(200) = 120
SD^2= np(1-p)
SD = sqrt(200(0.6)(1-0.6))
SD = 6.928
B) the mean of binomial distribution in this case is the average number of samples you’ll have to take before you achieve a sample of 200 where 60% of smokers who started smoking before 18.
Answer:
Step-by-step explanation:
use substitution and solve this 8x+4(-2x+3)=12
with the 4 distributed its
8x-8x+12=12
then you can cancel out the 8x and -8x and switch the 12 over into a -12 canceling out the 12s making it x=0
Answer:
x= 45 degrees
Step-by-step explanation:
the top angle is a eight angle which is equal to 90 all triangles are 180 degrees both bottom angles are equal and 180 minus the 90 degree from the right angle is 90 degrees you divide that by 2 and you have your answer
