Answer:
3 > n - 1 = n < 4
t − 3 > −2 = t > 1
4 < p - 2 = p > 6
2 ≥ h − 5 = h ≤ 7
v − 5 > −9 = v > 4
p + 3 ≤ 4 = p ≤ 1
- 7 < 7 + t = t > 14
6 + k > 5 = k > 1
12 ≤ r + 5 = r ≥ 7
w − (−4) < 8 = w < 4

Answer:
11
Step-by-step explanation:
Answer:
You are given:
4Fe+3O_2 -> 2Fe_2O_3
4:Fe:4
6:O_2:6
You actually have the same number of Fe on both sides, The same is true for O_2 so yes this equation is properly balanced.
For added benefit consider the following equation:
CH_4+O_2-> CO_2+2H_2O
ASK: Is this equation balanced? Quick answer: No
ASK: So how do we know and how do we then balance it?
DO: Count the number of each atom type you have on each side of the equation:
1:C:1
4:H:4
2:O:4
As you can see everything is balanced except for O To balance O we can simply add a coefficient of 2 in front of O_2 on the left side which would result in 4 O atoms:
CH_4+color(red)(2)O_2-> CO_2+2H_2O
1:C:1
4:H:4
4:O:4
Everything is now balanced.
Step-by-step explanation:
Answer: 0.4
Step-by-step explanation:
We know that the standard deviation of the sampling distribution of mean is given by:-
Given : Standard deviation : 
Sample size : n= 25
Then, the standard deviation of the sampling distribution of mean times will be :-
Hence, the standard deviation of the sampling distribution of mean times=0.4
The slope of the rise over run.
