Answer:
Step-by-step explanation:
Given that in the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College.
Table is prepared as follows
Bus coll. Lib Arts coll Educ. coll Total
Observed 90 120 90 300
Expected p.c. 35 35 30 100
Expected number 105 105 90 300
Percent*300/100
Hence expected frequency for business college = 105
Answer: 87%
Solution:
87 correct questions over 100 = 87/100 = .87 = (change to percent by moving the decimal 2 places to the right) 87%
Solve for g:
2 g = 9 - 7 g
Add 7 g to both sides:
2 g + 7 g = (7 g - 7 g) + 9
7 g - 7 g = 0:
2 g + 7 g = 9
2 g + 7 g = 9 g:
9 g = 9
Divide both sides of 9 g = 9 by 9:
(9 g)/9 = 9/9
9/9 = 1:
g = 9/9
9/9 = 1:
Answer: g = 1
