From historical data at a local restaurant indicate that 60% of the customers order coffee, 15% order soft drinks, and the remaining order water. the owner of the restaurant is planning on opening a new restaurant and for purposes of stocking enough of the various drinks, wants to know if the proportions are the same for his new restaurant as they were for his original restaurant. in a sample of 1000 customers at the new restaurant, 550 ordered coffee, 190 ordered soft drinks, and the remaining simply wanted water. at the 5% level of significance, does it appear the proportions have changed?

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

(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
