Answer:
d
Step-by-step explanation:
To use the binomial distribution, we need p and 1 - p
and so, since 1-0.3 is same as 0.7
for the 50th percentile, we have that the values of the two are equal
The 50th percentile in this case is that probably, we are selecting 50 out of a total of 100
2x +3x- 5= 0
5x-5=0
5x=0+5
5x=5
x=5÷5
x=1
Is it bad that I'm a senior and have no idea how to do this?
