U divide 330 by 15 and get the quotient then do the same thing to 20 and add the quotients together to solve for x and y
It would be 734.16 because 638.40+15% = 734.16
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 
The model shows 5x-9=-3x+20
Solve for x:
5x-9=-3x+20
5x=-3x+29
8x=29
x=29/8
Answer:
14/15
Step-by-step explanation:
Find common denominators. Note that what you do to the denominator, you do to the numerator.
Use 15 as the common denominator:
(-2/5)(3/3) = (-6/15)
(4/3)(5/5) = (20/15)
Combine like terms:
-6/15 + 20/15 = (20 - 6)/15 = 14/15
14/15 is your answer.
