Mr. bryant is trying to figure out which class project to work on for community service. he surveyed the junior and senior students about their preferred project. the frequency table shows the responses of the students.
juniors seniors total
park cleanup 30 26 56
food kitchen 50 34 84
clothing drive 10 50 60
total 90 110 200
determine the joint frequency of being a senior and wanting to have a park cleanup. explain what this answer represents.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

sorry i got nothing

step-by-step explanation:

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
