an oil tank, which is a shape of a cylinder, is 3m high and has a diameter of 6m. the oil tank is two-thirds full. find the numb
1 answer:
Answer:
Step-by-step explanation:
The key is to find out the entire volume the tank can hold when it is full, then take 2/3 of that amount. The volume of a cylinder is
and filling in:
(if the diameter is 6 m, the radius is 3) so
V = 84.78 m³ when it is full all the way. If we need the amount that makes up 2/3 of that:

Answer:
Step-by-step explanation:
Let's use binomial distribution, because we are interested in find the total number of successes in a sequence of n independent experiments.
In probability, a binomial distribution is used in a Bernoulli process. That is, a sequence of experiments of n independent trials, each asking a dichotomous question, that means it only has two answers. One answer is a success (probability: p) and the other is a failure (probability: 1-p). In this case, every customer who enters in the store is the experiment. If they make a purchase is a success event, taking into account that every purchase decision has to be independent.
x= total number of success
n= total number of experiments
p=probability of success on an indivual trial
a) x= 5 ------> customers that make a purchase
n= 6 ------> total customers
p=0.3
b) At least 3 customers make a purchase. x ≥ 3
c) At most 2 customers make a purchase. x ≤ 2
d)At least 1 customer makes a purchase. x ≥ 1
e)They must be kind to customers, always willing to help and give information about products clearly and honestly.
Have enough inventory and offer promotions for the purchase of more than one product
Have an agile payment system that avoids rows and delays in purchases.
