Answer:
D. 5
Step-by-step explanation:
Mean: (50+60)/2
110/2
55
Margin of error:
60 - 55

7/10 you just get the decimal form of the numbers and find a simple decimal between them, which was 7, and put it over 10 so you get 7/10
Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
Answer:
49
Step-by-step explanation:
So it seems theres some sort of pattern. When you mutiply 7 by 3 you get 21. When you multply 5 by 7 you get 35. So basically 7 times 7 would be 49. Correct me if im wrong.
Answer:
Im certain The answer is -4
Let me know if im wrong :)
