Answer:
21
Step-by-step explanation:
Ok, so this may be confusing but I’ll explain.
Here is a very simplified diagram:
1-2, 1-3, 1-4, 1-5, 1-6, 1-7
2-3, 2-4, 2-5, 2-6, 2-7
3-4, 3-5, 3-6, 3-7
4-5, 4-6, 4-7
5-6, 5-7
6-7
*Note- I did this in about 30 seconds and on my phone so it is very simplified *
Each number, 1-7, is supposed to represent a different ingredient and they are put together to represent the two-ingredient combinations.
For example: 1-2 could represent pepperoni and sausage, and 1-5 could represent pepperoni and olives. This would mean that the 1 represents pepperoni, 2 represents sausage, and 5 represents olives.
If you count the number of combinations in each row, there are 21 combinations. This is because I made sure there are no repeats (2-3 AND 3-2) and because there wouldn’t be any doubles (1-1 or 2-2)
The total mass was 149.5 grams.
Setting up an equation, we have that the sample size, 39.1, is 5 3/4 (5.75) grams less than 3/10 of the total mass; this gives us
39.1 = 3/10x - 5.75
Adding 5.75 to both sides, we have
44.85 = 3/10x
Multiplying both sides by 10,
448.5 = 3x
Dividing both sides by 3,
149.5 = x
30xt^3y is equivalent to 5(6xt3y)
Answer:
The answer is 1.2...
Step-by-step explanation:
If you look at the part y on the table and look at all of the points, you can see that every number increases by 1.2 points every single number. So, the constant proprotionally is 1.2
Hope this helps dude:)
