Answer:
The number of the students who got selected are 4,13,22,31.
Step-by-step explanation:
The professor wants to select 4 students randomly.
She randomly select the fourth and every ninth student after that
First the 4th student is selected
Now by using the next term formula which is
=>a + d(n-1)
The next student is the 2nd student.
=>4 + 9(2-1)
=>4 + 9(1)
=>4 + 9
=> 13
The 3rd student will be
=>4 + 9(3-1)
=>4 + 9(2)
=>4 + 18
=> 22
The 4th student will be
=>4 + 9(4-1)
=>4 + 9(3)
=> 4+ 27
=> 31
Subtract 3 from 3 and 6
Then multiply by -2 on both sides
Answer:
60%
Step-by-step explanation:
First, find the total number of sixth graders
To do this, add the number of girls and boys together
girls+boys
There are 60 girls and 90 boys
60+90
150
Now, find the percent of sixth graders that are boys
To do this, divide the number of boys by the total number of sixth graders
boys/total sixth graders (part/whole)
There are 90 boys, and 150 total sixth graders
90/150
0.6
Convert to a percent. Multiply by 100 or move the decimal place two spots to the right
0.6*100=60
0.6-->6.0-->60.
So, 60% are boys
