1) A biology professor reports that historically grades in her introductory biology course have
been distributed as follows: 15% A's, 30% B's, 40%TC's. 10% D's, and 5% F's. Grades in her
most recent course were distributed as follows:
Grade
B
D
Frequency 89 121 7825 12
A
c
F
Test an appropriate hypothesis to decide if the professor's most recent grade distribution
matches the historical distribution. Give statistical evidence to support your conclusion

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
