The box plot shows the number of years during which 16 schools have participated in a marching band competition: a box plot is titled years of participation and labeled years. number line from 0 to 10 with primary markings and labels at 0, 5, and 10. the box extends from 3 to 7 on the number line. there is a vertical line at 5. the whiskers end at 1 and 10. at least how many schools have participated for 3 to 7 years? (4 points) 3 schools 5 schools 7 schools 8 schools

From the given box and whisker's plot, we have

Now, we know that there is half data distributed between the lower and upper quartiles.

Also, we have to find that how many schools have participated for 3 to 7 years. It means we need to find the number of years in between Q1 and Q3.

The total number of schools is 16.

Hence, number of schools have participated for 3 to 7 years is given by half of the total number of schools.

=

Therefore, 8 schools have participated for 3 to 7 years.

D is the correct option.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
