Question

Please help me with number 7 I WILL GIVE BRAINLEST TO WHOEVER EXPLAINS AND SHOWS THE WORK

Answer 1

Since you're looking for students who scored at least 81, then you're looking at the last two rows on the table, because 81-90 and 91-100 are all at least 81. Add those number of students together, 20 + 7 = 27

Now, add up all the students in the table, which should equal 50. Since 27 out of 50 students made at least an 81, divide the numbers.

$\frac{27}{50} = 0.54$

Move the decimal to the right two times, and your answer will be 54%
