100/1200= x/100
cross multiply
(1200 * x)= (100 * 100)
1200x= 10000
divide both sides by 1200
x= 8.333% winning chance
LOSING CHANCE
100% - 8.333%= 91.667%
RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance
100:1100
simplify by 100
1:11 odds of winning to losing
ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.
Hope this helps! :)
Same-side interior angles where a transversal crosses parallel lines are supplementary:
The solutions to these equations can probably be done in your head:
- y = 180/(6+4) = 18
- x = (180-90)/5 = 18
The angles at the bottom of the figure, shown as different, are actually the same: 90°.
The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.
Answer:
The confidence interval for the population mean μ is 
Step-by-step explanation:
Given :
Number of weights of newborn girls n=185.
Mean 
hg
Standard deviation s=7.5 hg
Use a 95% confidence level i.e. cl=0.95
To find : What is the confidence interval for the population mean μ?
Solution :
Using t-distribution,
The degree of freedom 
The t critical value is t=1.973.
The confidence interval build is
Substitute the values,
Therefore, the confidence interval for the population mean μ is
