The dot plot represents the prices of different brands of chocolate bars. each dot represents a different brand of chocolate. how many brands are included in this data set? a. 18 b. 19 c. 20 d. 21 e. 22

The correct answer option is E. 22

Step-by-step explanation:

We are given a dot plot which represents the prices of different brands of the chocolate bars.

Given that each dot on the dot plot represents a different brand of the chocolate, we can find the total number of chocolate brands that are included in the data set.

To find the total number of chocolate brands, we just need to add the number of dots represented against each price to get:

Total number of chocolate brands = 1 + 4 + 3 + 5 + 2 + 3 + 2 + 1 + 1 = 22

Therefore, 22 different brands are included in this data set.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
