8:3
Step-by-step explanation:
Divide each by 12 :)
Answer:
69%
Step-by-step explanation:
If Motor Works is selected, the probability that the worker is a female is 70%. If City Bank is selected, the probability is 68%.
But we don't know what company will be selected, we only know that they have the same probability, 50-50.
So, with 50% of probability the worker will be female with a 70% of probability (because they selected from Motor Works) and with 50% of probability the worker will be female with a 68% of probability (they selected from City Bank).
We express this as 50%*70% + 50%*68% = 69%
The multiplication means that both probabilities happen together and the sum means that happens one thing or the other (they select Motor Works or City Bank)
Answer:
I believe it is 12.
Step-by-step explanation:
12 - 3 = 9
Answer:
system 4.
Step-by-step explanation:
3x+6y=9
multiply by 2
6x+12y=18 ....(1)
-2x+-4y=4
multiply by 3
-6x-12y=12 ...(2)
add (1) and (2)
0+0=30
which is impossible .It has no solutions.
Answer:
<em>13.1</em>
Step-by-step explanation:
<em>Add all the number together and divide by the number of students (aka total number of responses reported)</em>
<em></em>
<em>16+13+19+16+8+10+10=92</em>
<em></em>
<em>92/7= 13.1428 or about 13.1</em>
