The answer is 63.53 subtracts 5.23 from 68.76
Answer:
2.5
Step-by-step explanation:
56(t+1/2)=70 t
56T + 28= 70T
28=70T-56T
28=14
2=T
s=T+ 1/2
S=2+ 1/2
S=2.5 hours
Okay so we gotta do whats in the lines first so 6+14 that’s gonna be 20 but the add the 70 and it’s gonna be 90
Answer:
There is a probability of 0 that the student plays both string and brass.
Step-by-step explanation:
Looking at the universal set, there are 40 students at this high school, 15 of which play string, 20 play brass, and 5 play neither (probably drummers). Note how there is no intersection of A and B, which is the probability we are looking for.
Since there is no intersection in the universal set between subset A and subset B, you can say that there is a probability of 0 since there is no overlap between the two subsets.
Cheers.
