Answer:
20/41
Step-by-step explanation:
The total of all students is ...
7 + 2 + 5 + 6 + 3 + 4 + 6 + 8 = 41
The total of students not studying chemistry is ...
7 + 2 + 5 + 6 = 20
Then the probability that a randomly-chosen student does not study chemistry is ...
p(not studying chem) = 20/41
Answer:
k=-8.
Step-by-step explanation:
Step 1: subtract 14 from both sides from "2.25k - 20 =6.5k +14"
Step 2: Subtract 2.25k from both sides from "2.25k-34=6.5k
Step 3: Divide both sides by 4.25 from -34=4.25x
Your answer is k= -8.
It says -8=k.
好吧,我不會說英語,但會說普通話,如果我不知道那會是8

The answer should be 14/15.
Step-by-step explanation:
The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.
Then you add both of them together.
-6/15 + 20/15 = 14/15
