Check the picture below.
the segment LOJ is a diameter, and therefore the arcLCJ made by that diameter will have a central angle of 180°.
that simply means that the arcLC is 180 - 94, or 86°.
the ∡LJC is an inscribed angle that is intercepting the arcLC, and therefore, by the inscribed angle theorem, it'll be half of arcLC.
Answer: (47.51, 54.49)
Step-by-step explanation:
Confidence interval for population mean is given by :-
, where n= sample size .
= population standard deviation.
= sample mean
= Two -tailed z-value for 
(significance level)
As per given , we have
n= 44
Significance level for 95% confidence = 
Using z-value table ,
Two-tailed Critical z-value : 
Now, the 95% confidence interval for the true population mean textbook weight will be :-
Hence, the 95% confidence interval for the true population mean textbook weight. : (47.51, 54.49)
Answer:
The median weight for shelter A is greater than that for shelter B.
The data for shelter B are a symmetric data set.
The interquartile range for shelter B is 4.
Step-by-step explanation:
Answer:
(4,1)
Step-by-step explanation:
3x - 12
Triple a number would be 3x instead of x cubed as it is not asking for a number multiplied by itself three times.
-12 is the second half as since you don’t know whether or not the variable will be larger or smaller than the constant, it is safer to put it on the other half.
Thus, this equation fills in the worded format.
Hope this helps!
