Answer:
1. x ≤ -8
2. y < -8
3. y < -11
4. n > 10
5. n ≤ -2
6. n ≤ 15
7. n ≤ -5
Step-by-step explanation:
Your goal is to get just the variable on one side of the inequality!
For example, take -2y - 4 > 18.
Add 4 to both sides. So... -2y - 4 + (4) > 18 + (4)
Now you get -2y > 22. Since y isn't by itself, let's divide both sides by -2.
So, (-2y / -2) > (22 / -2)
<u>Anytime you're dividing something by a negative, remember to FLIP THE SIGNS.</u> So instead of a greater than, it will now be a less than sign <.
Now you get, y < -11
A is -11
B is -11
C is 54
Hope it helps
Answer:
Sample relative risk is 10.
Step-by-step explanation:
We are given the following in the question:
Group 1 of coal miners: 30 out of 150 get lung cancer.
Group 2 of non-coal miners: 5 out of 250 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 10.
3(8x - 5) = -4(7 - 6x)
Distribute 3 and -4 inside their respective parentheses.
24x - 15 = -28 + 24x
Add 28 to both sides.
24x + 13 = 24x
Subtract 24x from both sides.
13 = 0
This is an untrue statement, so that means there are no solutions to this equation.
Your answer is no solution.
Answer:
So this one is dotted and this here is 2 is on the line right point 3 and -1 is below the line after 2
Step-by-step explanation:
-Remember:
+solid is >= or <=
+Dotted is > or <
-Slope is -1/2 and y-intercept: 3.
