Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) 4x - 3 = 2x + 7                                      collect like terms

   4x - 2x = 7 + 3                                    

   2x = 10                                                 divide both sides by the coefficient of x

   x = 5

b) 2x + 6 = 7x - 14                                     collect like terms

   2x - 7x = -14 - 6

   -5x = -20                                        divide both sidess by the coefficient of x

   x = 4

svlad2 [7]

Answer:

The expected number of admissions for the fall semester is approximately 1248 students.

Step-by-step explanation:

We are given the following information in the question:

Number of Students:      1,060         1,400        1,540

               Probability:       0.61           0.11            0.3

Formula:

\text{Expectation} = E(x) = \sum xP(x)

Expected number of admissions for the fall semester =

E(x) = \sum xP(x)\\= (1060\times 0.61) + (1400\times 0.1) + (1540\times 0.3)\\=1248.6

Hence, the expected number of admissions for the fall semester is approximately 1,248 students.
