Answer:
y=7600(5^(t/22))
Step-by-step explanation:
This is going to be an exponential function as it grows rapidly.
This type of question can be solved using the formula y=a(r^x), where a is the inital amount, r the factor by which the amount increases and x is the unit of time after which the amount increases.
x=t/22
a=7600
r=5
∴y=7600(5^(t/22))
Answer:
(0, 9]
Step-by-step explanation:
√81 = 9
We must take positive numbers into consideration here.
Answer:
a is not to scale but b is
Step-by-step explanation:
5:20
is the same as 5/20
and 5/20 is equal to 10/40
Answer:
. This means that there is a 31.51% probability that exactly one plant in the sample dies before producing any rhubarb.
Step-by-step explanation:
For each plant, there are only two possible outcomes. Either they are going to die before producing any rhubarb, or they are not. This means that we can solve this problem using the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
There are 10 plants, so .
5% of these plants will die before producing any rhubarb. This means that .
. This means that there is a 31.51% probability that exactly one plant in the sample dies before producing any rhubarb.
