Answer:
where question？
Step-by-step explanation:
i dont know the question it cant be solve
272, i just kept on adding 7 and 4 equally untill i got 748 and figured out you need 272 b and if it asks for a, the answer is 476
The general equation of direct variation is
y = kx,
where k is a constant.
To see if the given points are a direct variation, try a few points in the equation above. If you get the same value of k every time, it is direct variation. If not, then it isn't.
Let's start with x = 7, y = 11
y = kx
11 = k * 7
k = 11/7
For the first point, we get k = 11/7. For a direct variation, you must get k = 11/7 for every point you try.
Now let's try point (8, 13).
y = kx
13 = k * 8
k = 13/8
13/8 is not equal to 11/7, so since the value of k is different for different ordered pairs, it is not direct variation.
Answer:
1. 1 13/24
2. 5/12
Step-by-step explanation:
2/3 = 16/24
7/8 = 21/24
Add.
16/24 + 21/24 = 37/24
As a mixed number, this is 1 13/24.
3/4 = 9/12
1/3 = 4/12
Subtract.
9/12 - 4/12 = 5/12
Hope this helps!

add all numbers together and divide by 50(there are 50 numbers)
find the difference of each number and 67.92(the mean)
add all these numbers together and divide by 50
