Answer:
a) 0.1091
b) 0.9994
c) 0.5886
Step-by-step explanation:
X = the number of fish out of 20 that die after 24 hours
x = 0, 1, 2, . . . , 20
X~ Binomial (n= 20, p =0.20)
P(14 survive) = P(X = 6)
=
=0.1091
Similarly we can find out
P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994
P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886
Answer:
$2.99
Step-by-step explanation:
Given that:
Purchase price of cat calendar = $1.30
Markup = 100%
Hence, price at which the cat calendar was sold :
1.30 + 100%(1.35)
$1.30 + $1.30 = $2.60
Sales tax = 15%
Amount paid as sales. tax _
15% * 2.60 = $0.39
Total amount paid :
$2.60 + 0.39 = $2.99
