We use the negative exponent rule to change an expression with a negative exponent to an equivalent expression with a positive exponent. The rule states that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.
First, add to find the number of male and female students.
216 + 207 + 198 + 194 = 815 males
193 + 214 + 197 + 201 = 805 females
Second, add to find the total number of students
815 + 805 = 1620
Third, find the number of students in ninth and tenth grade.
216 + 207 + 193 + 214 = 830
Fourth, put into a fraction.
830/1620
Fifth, simplify the fraction.
830/1620 → 83/162
Therefore, the answer is C.
Best of Luck!
Hi there!
The answer would be B. The number 3 was rolled 5 times in 36 trials.
This shows that out of all 36 times the dice was rolled the number 3 faced upwards 5 times.
Hope this helps !
Multiply 5x11, and add it to 5/11, to turn the number into a single fraction; 60/11. The reciprocal is this number flipped upside down, so the solution is 11/60.
Therefore the solution is 11/60.
The answer would be 3.) 1
