-2(3x - 9) + 5x = -10
-6x + 18 + 5x = -10
-6x + 5x = -10 - 18
-x = -28
x = 28 <===
Given:
μ = $3120, population mean
σ = $677, population standard deviation.
The population is normally distributed.
n = 20, sample size.
At the 95% confidence level, the confidence interval is
1.96(σ/√n) = 1.96(677/√20) = 296.71
Th confidence interval for the mean is
($2823.29, $3416.71)
Answer: ($2823.29, $3416.71)
It is unlikely but possible to generate the same number 3 times because each number has the same probability of being generated at random.
hope this was helpful.
Answer:
n=40
Step-by-step explanation:
divide 32 by 80
32/80=0.4
0.4x100=40
n=40
The answer is D because the difference of the X and Y of both coordinates is 1, 3. If you halve that (0.5, 1.5) then add that to your first point (2, 2) then you get (2.5, 3.5) which is the same as (5/2, 7/2).
