Arepresentative sample of a population of middle school students contains 45 boys and 25 girls. from this sample, 27 and 15 girls prefer classical music. if the population contains 350 people, how many girls prefer classical music? , this is due tomorrow

Total population of representative sample = 45 boys + 25 girls = 70

Now out of these 70 students, 15 girls prefer classical music.

So for 70 students = 15 girls prefer classical music

Applying unitary method,

Number of girl students preferring classical music per student = 15/70

Now we have to find number of girls preferring classical music per 350 people.

It will be given as:

=75

If a population contains 350 people , then 75 girls prefer classical music.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
