Answer:
1209
Step-by-step explanation:
v= pi* r^2* h r= d/2
soda:
d = 2 r = 1
h = 5
grabage:
d = 24 r = 12
h = 42
volume G: 19000.35
volume S: 15.71
volume G/ Volume S = # of soda cans
Circumference = π × diameter
π × 9 = 28.274333882
To 1dp = 28.3
Circumference = 28.3 inches
Answer:
Step-by-step explanation:
given that certain tubes manufactured by a company have a mean lifetime of 800 hours and a standard deviation of 60 hours.
Sample size n =16
Std error of sample mean = 
x bar follows N(800, 15)
the probability that a random sample of 16 tubes taken from the group will have a mean lifetime
(a) between 790 and 810 hours,
=
(b) less than 785 hours

, (c) more than 820 hours,

(d) between 770 and 830 hours
=
