Answer:
I had done already.thanks for huge point and heart.
If y varies directly with x, means that they can be modeled by a linear equation, lets choose a line with 0 y intercept, that is:
y = mx + b
y = mx
where m is the slope of the line, now we plug in the data we have:
y = mx
20/3 = m(30)
solving for m:
m = (20/3)(1/30)
m = 20/90
m = 2/9
so the line equation, or function modeling the y and x relationship is:
y = (2/9)x
Answer:

Step-by-step explanation:
Given data:
random sample size n = 1000
Population size is N - 2,000,000
P = 0.49
We know


Probability for having X =520
sample proportion 




10% of 5000 is 500 and 500 times 8 is 4000 so the total amount due would be 9000 :)
Answer:
x = 20 degrees
Explanation:
With a 20 degree angle on the direct opposite side, it shows that x is also 20 degrees; and the other two angles would be 160 degrees.
Hope this helps :)
