The ABC company's brand has a market share of 30%. Suppose that in a survey, 800 consumers of the product are asked which brand
Anna007 [38]

Answer: 0.68

Step-by-step explanation:

given data:

ABC market share = 30%

number of customers surveyed = 800

probability that more than 32% prefers ABC

Solution:

32% of 800

= 256 persons

p ( x ≥ 256 )

= 1 - ( 256/800 )

= 1 - 0.32

= 0.68

the probabiliy that more than 32% of those who carried out the survey would prefer ABC brand is 0.68.

What is the value of x? pleeaseee answer!!!
BabaBlast [244]

If you look up "angles of 7 sided polygon" it would give a result of how many degrees polygons with 7 sides such as this one above would equal to. It's important to know that when finding x angles within.

7-sided polygons = 900 degrees in total

Since all the other angles except x are given, we can add all those up and set it equal to 900. So it would look like this:

139+121+125+126+158+120+x=900

Simply solve for x now.

139+121+125+126+158+120+x=900\\ \\ 789+x=900\\ \\ x=900-789=111

So x = 111 degrees.

Hope this helps!
