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.
Answer:
D
Step-by-step explanation:
D is the best Answer.
C is the hypotenuse of that right triangle. It is found using Pythagorean's Theorem.
which is to say that
and
. Taking the square root of both sides gives us that c = 10.
Answer:
3/4 liter per hour
Step-by-step explanation:
1/2=2/3x (multiply by 3 to get 2x)
1 1/2 = 2x (divide by 2 to isolate)
3/4 = x
3/4 liters per hour
Answer: This is what I got -3.5 + 8.3 + (2/4 - 3) x 5*2 - 6.7
