Answer:
Isosceles trapezoid
Step-by-step explanation:
-An isosceles trapezoid is also sometimes called a convex quadrilateral.
-It properties include:
- A line of symmetry can often bisects a pair of opposite sides.
- It has to obtuse alternating with each other after which a pair of acute angles alternate with each other i.e 80°, 80°,100°,100°
- It has a trapezoidal shape which by definition has a two pair of parallel sides.
- The angles on it's base or ceiling are equal hence the name Isosceles Trapezoid.
Solution :
It is given that :
Number of students in a random sample majoring in communication or psychology at an university = 250
Total number of students majoring in psychology = 100
Number of students majoring in psychology those who are happy = 80
So number of students majoring in psychology those who are not happy = 20
Total number of students majoring in communication = 250 - 100 = 150
Number of students majoring in communication those who are happy = 115
So number of students majoring in psychology those who are not happy = 35
a). Probability of the students happy with their major choices are
![$=\frac{80+115}{250}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B80%2B115%7D%7B250%7D%24)
= 0.78
b). Psychology major ![$=\frac{80+20}{250}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B80%2B20%7D%7B250%7D%24)
= 0.4
c). Probability of the students who are happy with the communication as the choice of major =
= 0.46
d). Students unhappy with their choice of major given that the student is psychology major =
= 0.018
The expression can represent the value of x in terms of R, m, n and k after rearranging.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
![\rm R = 4m\sqrt{\dfrac{xn}{k^3}}](https://tex.z-dn.net/?f=%5Crm%20R%20%3D%204m%5Csqrt%7B%5Cdfrac%7Bxn%7D%7Bk%5E3%7D%7D)
Square both side:
![\rm R^2 = 16m^2{\dfrac{xn}{k^3}}](https://tex.z-dn.net/?f=%5Crm%20R%5E2%20%3D%2016m%5E2%7B%5Cdfrac%7Bxn%7D%7Bk%5E3%7D%7D)
16m² x n = R²k³
x = (R²k³)/(16m²n)
The above expression represents the value of x in terms of R, m, n and k.
Thus, the expression can represent the value of x in terms of R, m, n and k after rearranging.
