This is what the diagram is saying
(-4)+(-9)= -13
Answer:
Ok I will help you answer the first one the rest yourself?
Step-by-step explanation:
So the question is
6(r-s+t)
we have to time each number by 6
6r-6s+6t
That's how we can simply so the answer is 6r-6s+t
Same thing goes with the others

Answer: -4 is the answer
Step-by-step explanation:
Alright, 7% of 59.50 is 4.17
59.50 + 4.17 is 63.67
(sorry, I misread your question last time)
Both of these conditions must be true in order for the assumption that the binomial distribution is approximately normal. In other words, if 
and 
then we can use a normal distribution to get a good estimate of the binomial distribution. If either np or nq is smaller than 5, then a normal distribution wouldn't be a good model to use.
side note: q = 1-p is the complement of probability p
