To solve this, you must subtract .56 from -1.64. Then divide that by -5.5x. So the answer is .4
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)
Answer:
It's A
Step-by-step explanation:
would u like me to explain it??
1) Distribute
4 (v+5) -7v
4v + 20 - 7v
2) Combine 4v and -7v
-3v + 20
Therefore, the answer is -3v + 20
Answer:
a=7 b=11 c=9
Step-by-step explanation:
-2-(9) -2-(9) = -2+9=7 b -2-9=-11 c -2-(-9)-(-2) = -2+9+2=9
