Slope :
--------------------------
Slope = 5/8
--------------------------
Equation:
--------------------------
y = 5/8 x + b
--------------------------
Find y-intercept :
--------------------------
At (8, 2),
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3
--------------------------
Equation :
--------------------------
y = 5/8x - 3
-----------------------------------------------------------------
Answer: y = 5/8 x - 3
-----------------------------------------------------------------
3.5x10^4
lets break it down
10^4= 10x10x10x10 so 10,000
so therefore 3.5x 10,000= 35,000

Answer:
the answer is C- 6.53 inches
Step-by-step explanation:
Average (mean) = (sum of all the data) / (# of data)
sum of all the data = (average)(# of data)
Thus for 100 students with an average of 93,
sum of all data = (93)(100) = 9300
and for 300 students with an average of 75,
sum of all data = (75)(300) = 22500
Therefore you would expect the overall average to be
(9300 + 22500) / (100 + 300) = 79.5 %
Now if there are x # of advanced students and y # of regular students, then
x + y = 90 (total # of students) and 93x + 75y = 87(x + y) (overall average)
The second equation can be simplified to x - 2y = 0
Subtracting the two equations yields
x = 60 and y = 90
Therefore you would need 60 advanced and 30 regular students.
