A survey in one middle school showed that 3 out of 5 students enjoy playing dodgeball. Predict the number of students that enjoy playing dodgeball if there are 485 students in the school.

291 students

Step-by-step explanation:

The survey showed that out of a given number of students, 3 out of 5 students probably enjoy playing dodgeball.

If there are 485 students at the school therefore, the number of students who probably enjoy playing dodgeball are:

= Probability * Number of students

= 3/5 * 485

= 291 students

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
