Answer:
Step-by-step explanation:
this idea is probably a good thing to have a solid understand of. That Cartesian (rect) is the x and y components, of the legs of a triangle and is a way to measure that part of the two leg of the triangle that is made up by those pieces.. while the polar system would measure the hypotenuse of that same triangle with the degrees as a way to place where that hypotenuses goes
the abs value of an imaginary number will give you that distance from the origin to the point.. if you are using that sqrt ( +
) to get the abs. this is the same as the magnitude and can represent a total force. The distance between the origin and the point is that idea of two points.. conveniently we used (0,0) the origin as one of the points.. the other is at the top of the line or the point given by the complex number
Hopefully that helps... :/
Answer:
The probability that 85% or more of the sampled mussels will be infected is 0.1057.
Step-by-step explanation:
Let <em>X</em> = number of mussels infected with an intestinal parasite.
The probability that a random selected mussel is infected with an intestinal parasite is, <em>p</em> = 0.80.
A random sample of <em>n</em> = 100 mussels from the population are examined by a marine biologist.
The random variable <em>X</em> follows a Binomial distribution with parameters n = 100 and p = 0.80.
But the sample selected is too large, i.e. <em>n</em> = 100 > 30.
So a Normal approximation to binomial can be applied to approximate the distribution of <em>, </em>the sample proportion of mussels infected with an intestinal parasite, if the following conditions are satisfied:
- np ≥ 10
- n(1 - p) ≥ 10
Check the conditions as follows:
n × p = 100 × 0.80 = 80 > 10
n × (1 - p) = 100 × (1 - 0.80) = 20 > 10
Thus, a Normal approximation to binomial can be applied.
So, the distribution of is:
Compute the probability that 85% or more of the sampled mussels will be infected as follows:
Apply continuity correction:
*Use a <em>z</em>-table for the probability.
Thus, the probability that 85% or more of the sampled mussels will be infected is 0.1057.
