The answer is B.
If a coin is flipped 14 times and lands on heads 10 times the fraction would equal to 10/14.
10/14 simplifies to 5/7.
3 x 15 = 45
3 x 14 = 42
--------------
There are 14 packages.
----------------
x = 42/3
-----> 3x=42
Kilograms would be the most appropriate way
Answer: C.
There are 215 total students in the band.
There are 27 seniors in the band.
The probability is found by dividing the number of seniors in the band by the TOTAL number of students in the band.
P(S|B) = 27/215 = 0.1255813953
You have to round off the answer too the nearest tenth.
P(S|B) = 0.13
Do the following:
$8.40-$7.15=$1.25
Then divide 1.25 by the difference of tickets which is 3
1.25/3=0.42 (that's rounded to nearest cent)
