Answer:
<h2>12.5</h2>
Step-by-step explanation:
That would be 12.5 because 12.51 is closer to 12.50 than it is compared to 12.6.
Answer: Correct critical value = 2.2622
Step-by-step explanation:
Confidence interval for population mean when population standard deviation is unknown:
, where 
= sample mean, n= sample size, s= sample standard deviation, 
= two-tailed t value.
As per given: n= 10
degree of freedom : df = n-1=9
Critical t-value : 
So, the 95 percent confidence interval estimate for the mean :
The 95 percent confidence interval estimate for the mean:(190.14, 295.06)
6t+12-4t
Use the distribution property.
Answer:
Step-by-step explanation:
If we call the points she scored in the last game x, we can actually write out an equation to describe what is being said. 20=11+(3/5)x. Hopefully that makes sense. 3/5 of the previous score plus 11 is 20. Anyway, you can just solve this algebraic expression for x.
20=11+(3/5)x subtract 11 from both sides
9 = 3/5 x Multiply both sides by 5
45 = 3x then divide both sides by 3
15 = x And there you go.
Answer:
1 I think but you said they all have the same area
