Answer 1

Step-by-step explanation:

a) The most preferred salad dressing is the one with the highest percentage on the pie chart

That is the Ran

d) We want to get the percentage that preferred ranch

From the piechart, we can see that 55% of the people preferred ranch

e) The percentage we are talking about in this question takes two portions of the pie chart

Hence, we will add the percentages of Italian and Thousand Island

Mathematically, we have the sum as 32 + 13 = 45 %

f) From the piechart, 55% of respondents preferred ranch

This is equivalent to:

`(55)/(100)*200\text{ = 110 people}`

g) We use the approach we applied in the last question

We have this as 13% of 300

This is equivalent to:

`(13)/(100)*300\text{ = 39 people}`
