A square patio has an area of 200 square feet. how long is each side of the patio to the nearest 0.05?
ivolga24 [154]
Okay. So to find the answer to this, let’s do 200 squared. When you find the square root of 200, you get 14.14213 and other odd numbers or 14.15 when rounded to the nearest half-tenth. Each side of the patio is about 14.15 feet.

How do you solve this problem 3/2=x/324<br> i'm stuck
zhannawk [14.2K]
You have to find a common denominator.  In this case it will be 486/324 = x/324.  Then you would have to turn the 324 around.  Then it will be 486/324 X 324.  Which would be 486.  Therefore.  X = 486.  Please tell me if I am wrong.  Your welcome!

The average daily volume of a computer stock in 2011 was ų=35.1 million shares, according to a reliable source. A stock analyst
Shtirlitz [24]

Answer:

a

   The  null hypothesis is  H_o :  \mu =  35 .1 \ million  \ shares

    The  alternative hypothesis  H_a  :  \mu  \ne  35.1\ million  \ shares

b

 The   95% confidence interval is  27.475   <  \mu < 37.925

Step-by-step explanation:

From the question the we are told that

      The  population mean is  \mu  = 35.1 \  million \ shares

      The  sample size is  n = 30

       The  sample mean is  \= x  =  32.7 \ million\    shares

       The standard deviation is  \sigma =  14.6 \ million\  shares

     

Given that the confidence level is  95\% then the level of significance is mathematically represented as

                  \alpha  = 100-95

                  \alpha  = 5\%

=>               \alpha  = 0.05

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

    The value is  Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as

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

substituting values

                E  =  1.96 *  \frac{ 14.6 }{\sqrt{30} }

                E  =  5.225

The 95% confidence interval confidence interval is mathematically represented as

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

substituting values

               32.7 - 5.225   <  \mu < 32.7 + 5.225

                27.475   <  \mu < 37.925
