Answer:
No, the reasoning is not correct.
Step-by-step explanation:
1. To get the correct answer, Akeem should first translate 1L into mL.
1L = 1000mL.
2. We now have the numbers 270mL and 1000mL. (Note: Even though 270 and 1000 aren't equal, we can go with the question.)
3. 270/1000 is how we describe the ratio before it's simplified.
4. Simplify.
270/1000 → divide 10 from both sides to start simplifying. → 27/100
We can't simplify anymore without going into decimals.
5. The correct answer would be 27:100.
Answer:
30 students
Step-by-step explanation:
The problem above can be solved using a Venn diagram :
Using the information given :
The number of students competing :
Band and chorus only (BnC) only = 5 - 4 = 1
Band and Orchestra (BnO) only = 6 - 4 = 2
Chorus and Orchestra (CnO) only = 7-4 = 3
Chorus only (C) = 13 - (1+4+3) = 5
Band only (B) = 14 - (1+4+2) = 7
Orchestra only (O) = 17 - (2+4+3) = 8
The Total Number of Bayview students who competed :
(8+7+5+3+2+1+4) = 30
Answer:
(11.242 ; 12.958)
Step-by-step explanation:
The confidence interval is obtained using the relation :
C. I = xbar ± Zcritical * s/√n
Given that ::
xbar = 12.1 ;
Standard deviation, s = 16.6
n = 1012
C. I = 12.1 ± 1.645 * (16.6/√1012)
C.I = 12.1 ± 0.8583881
C. I = 11.242 ; 12.958
