Answer:26/21
Step-by-step explanation:
Total number of students=21
Number of students that plays basket ball=12
Number of students that plays
baseball=14
Number of students that play neither of the games=5
Probability that a student chosen at random plays basket ball or baseball
=12/21+14/21
26/21

Answer:
Step-by-step explanation:
d) (-2 +4i) -( 3 + 9i) = -2 + 4i - 3 - 9i
= -2 - 3 + 4i - 9i
= -5 - 5i
e)3i(6 - 5i) = 3i *6 - 5i * 3i
= 18i - 15*i² {i² = -1}
= 18i -15*(-1)
= 18i + 15
= 15 + 18i
f) (-3 + 7i)(1 - 2i) = (-3)*1 - 2i * (-3) + 7i *1 - 2i* 7i
= -3 + 6i + 7i - 14i²
= -3 + 6i + 7i - 14*(-1)
= -3 + 6i+ 7i + 14
= 11 + 13i
log(3x) = log(2x-4)
taking antilog of both sides:
3x = 2x - 4
3x - 2x = -4 [subtracting 2x from both sides]
x = -4
and we're done already!
