Answer:
<
Step-by-step explanation:
because 4/6/7 is less than 0
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
Answer:
It compresses up 2
Step-by-step explanation:
A binomial distribution can only be used when there are 2 possible outcomes, no more, no less.
Looking at the situations given you are able to use a binomial distribution in 2 cases.
First is the quarter being flipped 3 times. There are only two possibilities (Heads or Tails).
Second is the 3 marbles being pulled out of the bag. There are only two types of marbles (Green and Blue).
Answer:
1.5 times per second
(1 time per second if rounded to a whole number)
Step-by-step explanation:
1 minuet is equal to 60 seconds
Because you are given 88 vibrations in one minute, you will divide 88 by 60 seconds. You want your answer in seconds.
88/60 gives us 1.466666667 on a calculator
So the guitar gives a vibration of 1.466666667 per second
If we round this, we get 1.5 vibrations per second
Or, if we round 1.4666 to a whole number then it is 1 vibration per second
