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.

7.211103 = 7.2
Step-by-step explanation:
(-6x³-9x²+60x)
-3x(2x²+3x-20)
-3x(2x-5)(x+4)
(0,0) (1.5, 0), (-4, 0)
All have a multiplicity of one, since the graph will go through those points and there are three intercepts and it is in the third degree.
Answer:
Step-by-step explanation:
Since J is the midpoint of HK, then HJ=JK and 3x+5=9x-3 solve for x
6x=8 x=8/6=4/3 so HJ=3x+5=3(4/3)+5=9 = JK HK=2(9)=18
the full segment HK is 18, each half of it is 9 =HJ=JK
