Answer:
3rd one
Step-by-step explanation:
it is the only one with a function and a straight line
For the bubble numbers put the second box in there, and for the chart put the first box.
Answer:
0.27 repeating.
Step-by-step explanation:
So to solve this we just have to use division.
1 clearly doesnt go into 3 at least one time, so we can add a decimal point and add a 0 to make it 30.
11 goes into 30 2 times, so we have:
0.2
and 30-22=8
So we can add another 0 and make it 80.
Then 11 goes into 80 7 times. So we have:
0.27
and 80-77=3
So again, add the 0, we have 30.
11 goes into 30 2 times, so:
0.272
and 30-22=8
Add another 0 we get 80.
11 goes into 80 7 times.
So finally, we have:
0.2727.
This is a repeating decimal.
This can be shown as:
0.<u>27</u>
So this is your answer!
I was a bit confused with which one it was on your answer key, but knowing that it is 0.<u>27</u> I am guessing you can chose!
Hope this helps!
Answer:
42%
Step-by-step explanation:
If the probability of the first machine breaking down is 30%, the probability of it operating normally is 100% - 30% = 70%
The probability of the second machine operating normally is 100% - 40% = 60%
So, the probability of both machines operating normally in one day is:
P = 70% * 60% = 0.7 * 0.6 = 0.42 = 42%
