Answer:
Step-by-step explanation:
well, in the equation y = kx
the constant or proportionality is k.
So, what do you think?
Answer:
the slope is 1/5
Step-by-step explanation:
5y=x-3
divide by 5
y = 1/5 x - 3/5
the slope is 1/5 and the y intercept is -3/5
Answer:
The probability is 0.0428
Step-by-step explanation:
First, let's remember that the binomial distribution is given by the formula:
where k is the number of successes in n trials and p is the probability of success.
However, the problem tells us that when there isn't a number of trials fixed, we can use the geometric distribution and the formula for getting the first success on the xth trial becomes:

The problem asks us to find the probability of the first success on the 4th trial (given that the first subject to be a universal blood donor will be the fourth person selected)
Using this formula with the parameters given, we have:
p = 0.05
x = 4
Substituting these parameters in the formula and solving it, we get:

Therefore, the probability that the first subject to be a universal blood donor is the fourth person selected is 0.0428 or 4.28%
An exponential model is used to represent growth of a population
The population after 3 years is 2585
The function is given as:

<em>3 years after</em>, means that x = 3
So, we have:

Evaluate exponents


Approximate

Hence, the population after 3 years is 2585
