x would be equal to 1
step-by-step explanation:39.99 - $6.00 = 33.99
change 15% into a decimal > 0.15
multiply 0.15 and 33.99
33.99 x 0.15 = 5.0985
in this situation were the answer is in money my teacher would make me round so the answer would be 5.10 so i would say the answer is $5.10
i hope this : )
the probability is 8 over 15.
14 of the musicians play both guitar and drums, 28 play drums, 18 play the guitar.
it means n(g and d)=14, n(d)=28, n(g)=18.
using the formula of union: -
n(g or d) = n(g) + n(d) - n(g and d).
n(g or d) = 18 + 28 - 14.
n(g or d) = 32.
it says 60 musicians applied for a job at a music school. so n(u)=60.
the probability that the applicant who gets the job plays drums or guitar is = n(g or d)/n(u) = 32/60 = 8/15.
hence, the probability is 8 over 15.
i'm trying to do the same problem
