A survey for brand recognition is done and it is determined that 68% of consumers have heard of Dull Computer Company. A survey of 800 randomly selected consumers is to be conducted. For such groups of 800, would it be unusual to get 634 consumers who recognize the Dull Computer Company name?

yes , it would be unusual to get 634 consumers who recognize the Dull Computer Company name .

Step-by-step explanation:

Given  -

A survey for brand recognition is done and it is determined that 68% of consumers have heard of Dull Computer Company.

The probability of success is ( p ) = = .68

The probability of failure  is ( q )  = 1 - p =.32

Sample size (n) = 800

mean

              =

              = 544

Standard deviation =

                                     =  

                                     = 13.2

Maximum usual values =

                                      =

                                      = 570.4

634 is more than 2 standard deviation above the mean, it would be unusual to get 634 consumers who recognize the Dull Computer Company name

step-by-step explanation:

if x = 2 you have to find x to finish the problem

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
