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.
9. C : The scale is two inches for every three miles.
10 : 1.3 inches
Answer:I dont know if this is right but
A: 384 in.
B: 1040 in. = 86 ft
C: because the dimensions are multiplied by 26 inches, the perimeter for the actual flower bed is converted into feet.
Step-by-step explanation:
A: (8*2)+(12*2) = 384 in.
B: ((8*26)*2)+((12*26)*2) = 1040 in. = 86 ft.
(2,3) and (-1,-5)
Distance =√(-1-2)^2 +(-5-3)^2
Distance =√73 (diamter)
radius = (√73) / 2
area of semi-circle:
= 1/2 πr^2
= 1/2 π ((√73) / 2)^2
= 73 π / 8
= 9.125 π
area of triangle:
= 1/2 (8)(3)
= 12
Area of the figure = area of semi-circle + area of triangle<span>
</span>= 9.125π + 12
answer
9.125π + 12
