(Small sample confidence intervals for a population mean) suppose you are taking a sampling of 15 measurements. you find that x=
Luda [366]

Answer:

The 99% confidence interval is  71.67 < \mu < 78.33

Step-by-step explanation:

From the question we are told that

     The sample  size  is  n  =  15

      The  sample  mean is  \= x  =  75

        The  standard deviation is  s =  5

 Given that confidence is  99%  then the level of significance is mathematically represented as

              \alpha  =  100 -  99

             \alpha  =  1\%

             \alpha  =  0.01

Next we obtain the critical values of  \frac{ \alpha }{2} from the normal distribution table

   The  value is

                  Z_{\frac{ \alpha }{2} } = 2.58

Generally the margin for error is mathematically represented as

            E =  Z_{\frac{ \alpha }{2} } *  \frac{ s}{ \sqrt{n} }

=>         E =  2.58  *  \frac{ 5}{ \sqrt{15} }

=>         E =  3.3307

   The  99% confidence interval is mathematically represented as

             \= x  -E  <  \mu  <  \= x  +E

=>          75 -  3.3307 <  \mu

=>          71.67 < \mu < 78.33

What is the height of an isosceles trapezoid, if the lengths of its bases are 5m and 11m, and the length of a leg 4m
son4ous [18]

In the isosceles trapezoid ABCD, draw two perpendiculars AM and BL from A and B to the side CD.  

Now, LM = BA = 5 m  

CD = CL + LM + MD

       = CL + 5 + CL (CL = MD)

      = 2CL + 5  

But, CD = 11

Therefore, 2CL + 5 = 11

2CL = 11 - 5

       = 6

CL = 6/2 = 3m

MD = 3m

Now, consider the right triangle AMD.

We have,  

AM^{2} = AD^{2} - MD^{2}

                  = 4^{2} - 3^{2}

                  = 16 - 9

                 = 7

Hence, height of the isosceles trapezoid = AM = \sqrt{7} m

9р - Зр equivalent expression​
Vesnalui [34]

Answer:

6p

Step-by-step explanation:

9p - 3p needs to have the like terms combined. 9 - 3 is 6, and since you have to keep the p, the answer is 6p.
