<span>"how many more students in a class of 270 students would be expected to choose country than rock?"</span>

In order to answer this question, we need to know how many students choose <span>country, and </span>how many students choose rock

From the graph, we could read that 30 students choose country, and 20 students choose rock.

So that, the difference between these two number is 30-20= 10 more students choose country than rock

But the students' number is 270, not 90 as is in the graph

so we would multiply our result by 3 to get the right number of students

10*3=30 students

I hope that helps!

Based on ur graph, in a class of 90 students (20 rock, 40 hip hop, and 30 country...added = 90) , 30 chose country....30/90 reduces to 1/3.....so 1/3 chose country.

In a class of 450 students......1/3 * 450 = 450/3 = 150 chose country

Hope this helps!

When x increases from a to a +2, y increases by a factor of 1/4
Troyanec [42]

Answer:

y=7* (0.5)^x

Step-by-step explanation:

We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.

i.e. when x=a and x'=a+2.

then y/y=0.25 where y' is the function after putting x' to the old function.
