Answer: 2/3x-12=48
remember that less than means it goes to the back
Answer:
the constant proportionality means the ratio between two directly proportional quantities.
so the constant proportionality will be 7.5÷6=1.25 or 10÷8=1.25 or 12.5÷10=1.25
constant proportionality should be same all through because it's a constant
Given Information:
standard deviation = σ = 15 ft²
Confidence interval = 95%
Margin of error = 2.5 ft²
Required Information:
Sample size = n = ?
Answer:
Sample size = n ≈ 139
Step-by-step explanation:
The required number of observations can be found using
,
Me = z(σ/√n)
Where Me is the margin of error, z is the corresponding z-score of 95% confidence interval, σ is the standard deviation and n is the required sample size.
Rearrange the above equation to find the required number of sample size
√n = σz/Me
n = (σz/Me)²
For 95% confidence level, z-score = 1.96
n = (15*1.96/2.5)²
n = 138.29
since the sample size can't be in fraction so,
n ≈ 139
Therefore, a sample size of 139 would be needed.
Equal
7 - 2 is 5
So it’s the same
13,500 at 5.2 for 8 years compounded semi-annually.
Total = Principal * (1 + rate/n) ^n * years
where "n" = number of compounding periods per year.
Total = 13,500 * (1 + .052 / 2) ^ 2 * 8
Total = 13,500 * (1.026) ^ 16
Total = 13,500 * 1.5078487226
Total = 20,355.96
