Answer:
17.37
Step-by-step explanation:
y varies inversely as the square root of x
Mathematically:
y = k.root x
We first find k here
To find k, we were made to know that y is 21 and x = 361
k = y/root.x
k = 21/root. 361
k = 21/19
now what is y when x = 247
From y = k.root x
y = 21/19 * root 247
y= 21/19 * 15.72
y = 17.37
Answer:

The intersection of the graphs is at (-3,4).
Answer:
5/3 < x < 10
Step-by-step explanation:
Answer:
2500
Step-by-step explanation:
10,000/3,000=10/3
10x750=7500
7500/3=2500
The relationship between two variables is called their correlation. The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship.
Also,
A scatter plot shows a positive trend if y tends to increase as x increases. A scatter plot shows a negative trend if y tends to decrease as x increases. A scatter plot shows no trend if there is no obvious pattern.
Hope this helps!
