Answer:

  B = 2M -A

Step-by-step explanation:

For given endpoint A and midpoint M, the other endpoint B can be found using the definition of the midpoint:

  M = (A+B)/2

  2M = A+B . . . . . multiply by 2

  2M-A = B . . . . . subtract A

The second endpoint can be found by subtracting the given endpoint from twice the midpoint:

  B = 2M -A

A hypothesis test is to be performed for a population proportion. For the given sample data and null hypothesis, compute the val
liberstina [14]

Answer:

The correct option is a

Step-by-step explanation:

From the question we are told that

    The sample size is n =  415

    The sample proportion is  \r p  = 0.49

Now

     The null hypothesis is  H_o  :  p = 0.3

     The alternative hypothesis is H_a  :  p \ne 0.3

The test statistics is mathematically evaluated as

      t  =  \frac{\r p -  p  }{ \frac{\sqrt{ p (1- p )} }{n} }

substituting values

      t  =  \frac{0.49 -  0.3  }{ \sqrt{ \frac{0.3 (1- 0.3 ) }{415} }}

     t  = 8.446

HELP ME WITH MY MATH ASSIGNMENT, WILL GIVE ANYTHING, DUE TOMORROW! :(
nataly862011 [7]

Answer:

Answer is 225.

We have to find the sum of 15 terms of the series

sigma 1 to 15 (2n-1)

This can be split as per summation terms as

sigma 2n - sigma 1

sigma 2n can again be simplified by taking 2 outside

sigma 2n= 2 times sum of natural numbers of 1 to 15

= 2(15)(16)/2= 240

sigma 1= 1+1+...15 times= 15

Hence final answer is

= 2 times sigma n - (n) = 240-15 = 225.
