Dobereiner's Triads are groups of three elements arranged in such a way that the atomic weight of the middle element is almost the average of the other two. The elements of triad have almost similar properties
no
I guess it's -24/7. So 24 divided by 7 is 3 remainder 3
The minus sign remains. So that will be -3 3/7
Hope I helped. Goodluck
Answer:
There’s only one way to get 12 when 2 dice are tossed, both have to equal 6. There are 6 ways tossing a single die can come out (1,2,3,4,5,6), so if you toss dice, the second die could have any one of six values with each of the numbers that could result from the first toss (e.g., 1 from die 1 and 1,2,3,4,5, or 6 from die 2). So, considering there are 6 ways to fill each of two slots, there are 6 x 6 = 36 possible outcomes of tossing two dice. Only one of them equals 12, so p(12 given 2 dice tossed) = 1/36 = 0.02777777777778.
Answer:
1 3/20
Step-by-step explanation:
The solution will be: 
<em><u>Explanation</u></em>
The given inequality is: 
First we will subtract 
from both sides. So.....
Now we will subtract 13 from both sides. So.....
Then we need to divide both sides by -3. As here we are <u>dividing the inequality by a negative number, so we need to switch the inequality symbol</u>. So, we will get.......
Thus, the solution will be:
