the question is based on the following circle graph. the graph represents the results of a survey in which 400 people were asked to identify the tv channel on which they preferred to watch the evening news.
wkod 13%
wanr 22%
wclm 24%
wwcn 41%
write a ratio to express the number of people who preferred wanr to those who preferred wclm
a. 11 : 12
b. 23 : 100
c. 46 : 100
d. 3 : 50

Option A is right

Step-by-step explanation:

The graph represents the results of a survey where 400 people were asked to identify the preferred TV channcel.

Of those the data collected gave

WKOD 13%

WANR 22%

WCLM 24%

WWCN 41%

Ratio of people who preferred WANR to those who preferred WCLM

= 22%/24%

=11:12

Hence answer is 11:12

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

there are no multiple choices
