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.
If the value of a is positive, the line slopes upwards.

Step-by-step explanation:
if u do KFC or KCF u can see its not equal
if pos divided by pos it equals pos
pos divided by neg is neg
neg divided by neg is pos
zero is the additive identify
a rational number between two rational numbers a and b is a plus b divided by 2

54 : 18 = 6 : 2
18 x 3 = 54
2 x 3 = 6
If he drives 50 mph and drives for 2 hours he will have gone 100 miles, 3 hours=150 miles, 4 hours=200 miles, 5 hours=250 miles.
If he drives 60 mph and drives for 2 hours he will have gone 120 miles, 3 hours=180 miles, 4 hours=240 miles, 5 hours=300 miles.
How I got the answer,
All you have to do is multiply, 60 mph is exactly that, "MILES PER HOUR" means if they drive 40 mph then in 1 hour they will have gone 40 miles, so if you want to know how many miles compared to hours you have driven, just multiply.
I hope this helps.
