The answer is x=6
hope this heelps
Alright my friend so basically if we subtract 5 from 71 we get 66 plus 8 would be 74 so we would have to drop the temp 3 degrees to get back to 71 so the answer will be option B. fall 3 degrees

Empirical probability of head
This is calculated as:
Answer:
x=10. x=-8. x=5. x=10. x=120.
Step-by-step explanation:
If your trying to find x then get x by its self.
3x=2x +10 subtract 2x from both sides
x=10
5x=4x-8 subtract 4x from both sides
x= -8
x +5=2x subtract x from both sides
x=5
3x+10=4x subtract 3x from both sides
x=10
120+5x=6x subtract 5x from both sides
120=x
1. The answer for this is (C). first you would add up all your probabilities as usual, so 9+16+9+6, which is going equal out to be 40 as your total. Knowing your total, you then move on to see how much of red balls you have. seeing that you have 16 red, you then put it on top of your total making the fraction 16/40, but since divisable, we divide by the highest number by the top and bottom number, therefore, we'll divide both numbers by 8, getting the your answer 2/5(C)
2. The answer is (C), and the reason I got that is because first thing your supposed to start out doing is adding up your number possibilities, so it wold be 12+11+7+10, getting the number 40 as your total. Now since it's asking for the probability of pulling out a black ball (10), we take that and the total and make them into a fraction getting 10/40, but since this number can be divided out equally, we'll use the highest number we can divide it by, but still get a equal number, so we'll divide it by 10, getting 1/4(C)
