Answer:
Step-by-step explanation:
Answer: 0.701
Step-by-step explanation:
Formula : 
, where 
significance level , 
Population standard deviation, n= sample size.
As per given, n= 22
Critical z- value for 90% confidence level : 
Then,
Hence , error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701
Answer:
35.235
Step-by-step explanation:
because 78.3*0.45 = 35.235
Answer:
\frac{x^4+5}{x^3(x^2+6)} =\frac{A}{x}+\frac{B}{x^2}+\frac{D}{x^3} +\frac{Ex+F}{x^2+6}
Step-by-step explanation:
Answer:
25.136 in
Step-by-step explanation:
Given data
Adult bicycle wheel
Diameter= 26in
Radius= 26/2= 13in
Circumference= 2πr
Circumference= 2*3.142*13
Circumference= 81.692 in
Child's bicycle
Diameter= 18in
Radius= 18/2= 9in
Circumference= 2πr
Circumference= 2*3.142*9
Circumference= 56.556 in
Hence the difference in the distance traveled in one revolution is the difference in their circumference
Distance= 81.692 -56.556
Distance= 25.136 in
