The firm is requested to send 3 employees who have positive indications of asbestos on to a medical center for further testing.

Rus_ich [418]

Answer:

0.0645 = 6.45% probability that exactly 10 employees will be tested in order to find 3 positives

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

40% of the employees have positive indications of asbestos in their lungs

This means that $p = 0.4$

a) Find the probability that exactly 10 employees will be tested in order to find 3 positives

2 within the first 9( $P(X = 2)$ when $n = 9$ ), and the 10th, with 0.4 probability. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{9,2}.(0.4)^{2}.(0.6)^{7} = 0.1612$

0.4*0.1612 = 0.0645

0.0645 = 6.45% probability that exactly 10 employees will be tested in order to find 3 positives

Can somebody please help me with this ?? :)

Neko [114]

The equation is: 3x^3 = 4x + 8

The form is ax^2 + bx + c = 0

Rewrite the given equation to equal 0:

Subtract 3x^2 from both sides to get:-3x^2 + 4x + 8 = 0

Now give each letter their value:

a = -3, b = 4, c = 8

Answer:

slope m = 1 y-intercept b = 3

Step-by-step explanation:

to double check you can do use the formula y=mx+b

-3*1= -3 +3= 0

so the coordinates would be (-3,0)
