Answer:
C 9i
D -9i
Step-by-step explanation:
sqrt(-81)
sqrt(81) sqrt(-1)
we know that sqrt(-1) = i
±9i
9.26%
total tiles 36,
4 will be test so probability of testing 4/36
non defective =30
probability of testing non defective 4/36 x 30/36 x 100=
9.26%
0.0058 is 0.58% (I think so)
64< 67< 125
64^ (1/3) < 67 ^ (1/3) < 125^ (1/3)
4 < 67^ (1/3) < 5
Choice 2
Answer:
40 Laps per Hour
Step-by-step explanation:
45 * 5 * 12 = 2700
2700/60 = 45
1800/45 = 40
