Turn 4 1/2 into a fraction which is 4.5, then divide that by three. 4.5 / 3 = 1.5. So 1.5 = 1/3 of the original amount. Now all you need to do is multiply 1.5 times 2. You do this because you know that 1/3 + 1/3 = 2/3. So 1.5 + 1.5 = 2/3. 1.5 * 2 = 3. Now you have 2/3 of the original number.

(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

The shaded area and the diameter
masha68 [24]

Answer:

  • 15.25 cm²

Step-by-step explanation:

<u>The diameter is the hypotenuse of the triangle:</u>

  • d = √8²+6² = √100 = 10 cm

<u>Area of the semicircle:</u>

  • A = 1/2πr² = 1/2(3.14)(10/2)² = 39.25 cm²

<u>Area of the triangle:</u>

  • A = 1/2bh = 1/2(6)(8) = 24 cm²

<u>Shaded area:</u>

  • 39.25 - 24 = 15.25 cm²
