Answer: 85.5

Step-by-step explanation:

There are 22 data points in the data set.

We can find the median by looking at the 11th and 12th scores, and averaging them.

The 11th score is 85

The 12th score is 86

The average of the two is 85.5

Hence the answer is 85.5

tatuchka [14]

Answer:

Number of boys in 7th grade=34 boys

Number of girls in 7th grade=51 girls

Step-by-step explanation:

Total Number of students in 7th grade=Number of boys+Number of girls

where;

Total number of students in 7th grade=85 students

Number of boys=x

Number of girls=(1 1/2)×Number of boys=(3/2)×x=1.5x

Replacing;

85=x+1.5x

2.5x=85

x=85/2.5

x=34

Number of boys=x=34

Number of girls=1.5x=1.5×34=51

Number of boys in 7th grade=34 boys

Number of girls in 7th grade=51 girls
