Step-by-step explanation:
W=t times 8 :)
When you are solving the equation you see that after 9 minutes there is 72 inches to find the unit rate you divide 9 by 72 and you get 8 so per each minute there is 8 inches of water
Answer:
Sample relative risk is 4.
Step-by-step explanation:
We are given the following in the question:
Group 1 of smokers: 10 out of 100 get lung cancer.
Group 2 of non-smokers: 5 out of 200 get lung cancer
Sample relative risk:
- It is the ratio of probability of an outcome in an exposed group to the probability of an outcome in an unexposed group.
Sample relative risk =
Thus, sample relative risk is 4.
Answer:
Step-by-step explanation:
Take this one thing at a time...baby steps to help us keep our sanity. Math does tend to drive a person around the bend...
The first term is the tricky one. If the exponent is negative, it can be rewritten as a positive by putting whatever the exponent is on under a 1. For example:
So we'll use that to make this simpler.
Squaring that negative makes it a positive, so we can rewrite as
which simplifies to
What we have there is a fraction over a fraction; namely:
and the rule for that is to bring the bottom fraction up, flip it and multiply:
× which is 4.
Now for the second part. All we are doing here is squaring that fraction. Remember that squaring a negative makes it a positive, so
. Now we'll put these together to get the sum
and with a common denominator of 4, this becomes
and that equals
, the seond choice down.
