I got 110 but it might be wrong let me check.
Answer: the answer = work for it
Step-by-step explanation:
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)
For this case, the first thing we must do is to group similar terms.
We have then:
n (9 + 15) + (12-6)
Rewriting:
24n - 6 ft
Answer:
(9n + 12) ft + (15n -6) ft = 24n - 6 ft
use the distance formula
You ll need to do it t times:
x1 y1 x2 y2
(-1, 5) (4, 2) = (-1, 5) (4, 2)
(4, 2) (0,0)
(0,0) (5,5)
(5,5) (-1, 5)
then add all your results
