Answer: 3.75
Step-by-step explanation:
P=0.50, n=15
np= 0.5x15 gives 7.5
n(1-p)= 15x(1-0.5)=7.5
Both are greater than 5
Then Mean, u=np;15x0.5=7.5
Standard deviation, √np(1-p)
15x0.5(0.5)= 3.75
Answer:
D, the lines coincide.
Step-by-step explanation:
isolate the y so theres no 2y, only y:
2y = 8 - 2x (divide both sides by 2)
y = 4 - x
The lines are the same line, so while they are plural, they also coincide, as one lies on top of the other.
