Use the relationships in the diagram below to write an equation and solve for X
Firlakuza [10]
A. x^2 + b^2 = c^2  
    x^2 + 18^2 = 30^2
    x^2 + 324 = 900
    x^2 = 900 - 324
    x^2 = 576
    x = sqrt 576
    x = 24 <===

b. (2x + 20) + (2x) + (x) + (3x + 20) = 360
     8x + 40 = 360
     8x = 360 - 40
     8x = 320
     x = 320/8
     x = 40

2x + 20 = 2(40) + 20 = 80 + 20 = 100
2x = 2(40) = 80
3x + 20 = 3(40) + 20 = 120 + 20 = 140

An Undergraduate Study Committee of 6 members at a major university is to be formed from a pool of faculty of 18 men and 6 women
Brums [2.3K]

Answer:

5/33649= approx 0.00015

Step-by-step explanation:

Total number of outcomes are  C24 6= 24!/(24-6)!/6!=19*20*21*22*23*24/(2*3*4*5*6)= 19*14*22*23

Half of the Committee =3 persons. That mens that number of the women in Commettee=3.  3 women from 6 can be elected C6  3  ways ( outputs)=

6!/3!/3!=4*5*6*/2/3=20

So the probability that 3 members of the commettee are women  is

P(women=3)= 20/(19*14*22*23)=5/(77*19*23)=5/33649=approx 0.00015
