0
because a whole number means that there should be no fraction, decimal or negatives
1/8 = 0.125
since you have to round down
the answer would be 0
Standard Form : ( x - 1 ) ^2 + ( y + 3 ) ^2 = 5
Center of the circle : ( 1 , -3 )
Radius: line mark over 5
29 is the median
If you just count all then the half number will be the 3rd 29
Answer:
Correct formula for a 99% confidence interval for the population mean =
Step-by-step explanation:
We are provided a simple random sample of 144 items of which sample mean, xbar = 1250.25 and Standard Deviation, s = 480.
We know that follows i.e.;
follows
So, 99% confidence interval is given by ;
P(-2.61138 < < 2.61138) = 0.99 {because at 143 degree of freedom t table
gives critical value of 2.61138 at 0.5% level}
Now, after further solving this we get,
99% confidence interval for the population mean =
Since, in the question options are not given so this must be the correct formula for calculating 99% confidence interval for the population mean.
∠CPB is a central angle, and so Arc:CB = 30 degrees
(if it is an inscribed angle than you multiply it by 2)
A circle is 360 degrees
Arc: AB is 180 degrees (half a circle)
Arc: CB is 30 degrees
360 - 180 - 30 = 150
Arc AC is 150 degrees
hope this helps
