Answer:

a.   x = 6.

Step-by-step explanation:

2(4x+5)-2=2x+44           First distribute the 2 over the brackets:

8x + 10 - 2 = 2x + 44

8x - 2x = 44 - 10 + 2

6x = 36

x = 6.

A local university has 2.815 Hispanic students out of a total student population of 20.250. Do the Hispanic students have propor
Over [174]
Given:
The race percent of population is
White:      45%
Hispanic: 27%
Black:       18%
Asian:        7%
Other:        3%

Part a.
The university has 2,815 Hispanic out of the 20,250 total population.
This is equivalent to (2815/20250)*100 = 13.9%
This percentage is less than 27%, so Hispanics do not have proportional representation.

Answer: The Hispanic students do not have proportional representation.

Part b.
Let x =  the extra number of Hispanic students needed for proportional representation of 27% or 0.27.
Then
(2815 + x)/20250 = 0.27
2815 + x = 20250*0.27 = 5467.5
x = 5467.5 - 2815 = 2652.5

This means that 2,653 extra Hispanic students are required for a population of 20,250 students.

Answer: 2,653 extra Hispanic students.
