The number = y
2y + 1/3 = 2/3 - 3y
(add 3y to both sides)
5y + 1/3 = 2/3
(subtract 1/3 from both sides to isolate y)
5y = 1/3
(divide by 5)
y = 1/15
Answer:
In 4 months
Step-by-step explanation:
If you keep subtracting 140nfrom 3440 u will get 2880 after you do that 4 times. If you keep adding 220 to 2000 you will get 2880 after you do it 4 times.
Answer:
The formula is
A=p (1+r)^t
A future value?
P present value 800
R interest rate 0.1
T time 8 years
A=800×(1+0.1)^(8)
A=1,714.87

Answer:
From this finding, it can be said that the sample proportion is greater than the population proportion because the test statistic (z = 2.45) is positive.
Step-by-step explanation:
H0: p = 0.35
Ha: p > 0.35
The test is a one-tailed test because the alternate hypothesis is expressed using greater than.
The test statistic (z) for a proportion is given as (p' - p) ÷ sqrt [p(1-p)/n]
p' is sample proportion
p is population proportion
n is sample size
For the test statistic z to be positive, p' must be greater than p.
