Answer: There are <u>4</u> teams in the league
Step-by-step explanation:
(1) Add 14 four times: 14+14+14+14 = 56
(2) Multiply 14 four times: 14 x 4 = 56
(3) Combine both of these numbers into the <em>t </em>factor: 14t = 56
(4) Divide both sides by 14 and simplify: (14t / 14) = 56/14 | t = <u>4</u> (simplified)
10 1/2 =
10/1 + 1/2=
2/2 (10/1) + 1/2=
20/2 + 1/2=
21/2
Answer: 24.9793
Step-by-step explanation:
Given : The director randomly selects 64 different 24-hour periods and determines the number of admissions for each.
For this sample, he calculated a mean
and a standard deviation of 100.
The 95% confidence interval results in an interval of 
We know that the confidence interval for population mean is given by :_
, where E is the margin of error.
By comparing this to the given interval , we find that the margin of error = 24.9793
