Hello,
|BD|=61
|JS|=|JB|+|BS|=84
|BS|=18 ==>|JB|=84-18=66
|JD|=|JB|+|BD|=66+61=127
Answer:
10/(9y)
Step-by-step explanation:
multiply y by 9: 9y
then divide 10 by the result: 10/(9y)
The answer is B. t = I/pr
Answer:
(11.605 ; 22.195)
Step-by-step explanation:
11 10 16 15 18 12 25 20 18 24
Sample mean, xbar = Σx / n = 169 / 10 = 16.9
Standard deviation = 5.152 ( using calculator)
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
Df = n - 1 = 10 - 1 = 9
Tcritical at 99%, df =9 = 3.2498
Margin of Error = 3.2498 * 5.152/√10 = 5.2946
Lower boundary :
16.9 - 5.2946 = 11.6054
Upper boundary :
16.9 + 5.2946 = 22.1946
(11.605 ; 22.195)
