Answer:
- Keisha’s experimental probability is 1/50.
- When the inventory is 4000 clocks, the prediction is that 3920 clocks will work.
- Keisha will have more than 97% of the products working.
Step-by-step explanation:
These are three prediction that Keisha can make based on the report that said 6 of 300 clocks tested weren't working.
Base on that information, Keisha can calculate an experimental probability, dividing <em>clocks that don't work properly </em>by <em>the total amount of clocks</em><em>:</em>
<em></em>
Therefore, the probability of success is 100% - 2% = 98%.
This means that Keisha has a probability of having 98% of all clocks functioning properly. So, she can make the prediction:<em> from 4000 clocks, 3920 will work. </em>Also, she can predict that she will actually have more than 97% working, because the experimental probability is higher than that.
-3/4, -7/10, 3/4, and 8/10.
Answer:
Step-by-step explanation:
The point-slope form of ane equation of a line:
<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point on a line</em>
<em />
We have:
y-intercept is for x = 0.
Therefore, if y-intercept = 0, then we have the point (0, 0).
Substitute:
The number 4 is in the tens place in the first number. In the second number, the number 4 is in the ones place
The answer is $782.28. First, you multiply 738 by .06 to get 44.38. You then add this to 738 to receive 782.28
