Answer:
40 degree acute
Step-by-step explanation:
Answer:
no
Step-by-step explanation:
y = 3x
Substitute the point into the equation
2 = 3*0
2 =0
This is not true so the point is not a solution
Answer: The answer would be $140
Step-by-step explanation:
Divide $80 / 4 which equals 20 and then multiply that times 7
Answer:
6!!!
Step-by-step explanation:
Since both 30 and 42 can both be answered by multiplying 6 by a different number
5 x 6 = 30
7 x 6 = 42
Answer:
You keep them if you test 3 and all pass.
There are 18 good ones and 6 bad (making 24)
Chance of first passing is 18/24
If it passes, there are now one less good and one less total.
Chance of second passing is 17/23
If it passes, there are now one less good and one less total.
Chance of second passing is 16/22
Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).
So probability all are ok is 0.4
Thus probability you find at least one bad one is 0.6
Hope this helps you out!
