Answer:
C. is incorrect.
Step-by-step explanation:
Calculate the percentages for each prize desired by the 50 students responding in the sample survey. See the attached image for this calculation. Multiply these percentages times the total student body of 225 students to determine the likely selection for each prize (on the attachment).
A. is correct (126 students)
B. is correct
C. is incorrect. The total is (54 + 27) = 83
D. is true
3 less: -3
difference of 16p and 15p: 16p - 15p = p
is equal to: =
the difference of 3 and 1/2: 3 - 1/2 = 2.5
p - 3 = 2.5
Isolate the p. Note the equal sign. What you do to one side, you do to the other. Add 3 to both sides
p - 3 (+3) = 2.5 (+3)
p = 2.5 + 3
p = 5.5
5.5 is your answer for p

Multiply both numerator and denominator with 8+5i. Then you get
Answer:
no solution
Step-by-step explanation:
3(x – 5) = 1/2 (6х- 12)
3х-15= 6/2х-12/2
3х-6/2х=15-12/2
3х-3х=15-6
0х=9 no solution
Answer: 8 fewer students
Step-by-step explanation:
