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

Please assist me with the trapezoid problems​
White raven [17]

Problem 4

a)

MR = AG is a true statement because MARG is an isosceles trapezoid. The diagonals of any isosceles trapezoid are always the same length.

-------------------------

b)

MA = GR is false. Parallel sides in a trapezoid are never congruent (otherwise you'll have a parallelogram).

-------------------------

c)

MR and AG do NOT bisect each other. The diagonals bisect each other only if you had a parallelogram.

=================================================

Problem 5

a)

LC = AJ (nonparallel sides of isosceles trapezoid are always the same length)

x^2 = 25

x = sqrt(25)

<h3>x = 5</h3>

-------------------------

b)

LU = 25

UC = 25 because point U cuts LC in half

LC = LU+UC = 25+25 = 50

AJ = LC = 50 (nonparallel sides of isosceles trapezoid are always the same length)

AS = (1/2)*AJ

AS = (1/2)*50

<h3>AS = 25</h3>

-------------------------

c)

angle LCA = 71

angle CAJ = 71 (base angles of isosceles trapezoid are always congruent)

(angleAJL)+(angleCAJ) = 180

(angleAJL)+(71) = 180

angle AJL = 180-71

<h3>angle AJL = 109 </h3>
