Answer:
C. mean: 6.4 and standard deviation: 2.31862028
Step-by-step explanation:
We are given
n=40
p=0.16
q= 1-p = 0.84
mean = np = 40*0.16 = 6.4
standard deviation =
= 
sd = 2.31862028
1.
yes
x is number of group acts
y is number of indivual acts
2. I would eliminate x by multiplying 2nd equation by -3 then adding
12x+6y=120
<u>-12x-3y=-90 +
</u>0x+3y=30
3y=30
divide by 3
y=10
sub
4x+y=30
4x+10=30
4x=20
divide 4
x=5
each group act takes 5 mins and each individual takes 10 minutes
