Answer:
just subtract it
Step-by-step explanation:
604-357=247
Answer: 95% confidence interval would be (26.01,29.39).
Step-by-step explanation:
Since we have given that
n = 50
Mean = 27.7
Standard deviation = 6.12
We need to construct 95% confidence interval for the population.
so, z = 1.96
So, it becomes,

Hence, 95% confidence interval would be (26.01,29.39).
Answer:
$65.60
Step-by-step explanation:
4×16.40 = 4×(16+0.40) = (4×16) + (4×0.40) = 64 + 1.60 = 65.60
Answer:
6x+3x=9x
2+7=9
9(x+1)
Distributive property
9x + 9
(im not completly sure this is the right answer)
