Answer:
Some of the 50 students should have been assigned to a control group that used the in-person course
Step-by-step explanation:
If all students scored the same the score of each student would be 4.5.
3/4 I’m pretty sure hejjejwiwiwjwnnsn
I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.
Let's start with the bottom,
a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)
Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)
And anything to the 0th power is 1, so your answer should be 1
Hope that helps!
