Try 75. I could be wrong but try it
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:
Y= 3.2b + 100
Step-by-step explanation:
That is the equation needed to find the value of b. since Omar bought the cup at the fixed price of 100 we know that no matter what the answer has to be over 100. So that becomes our Y intercept. 3.2 percent is how much the price inflates every year.
Answer:
1000
Step-by-step explanation:
Answer: x≤350
(x=the amount of visitors)
Step-by-step explanation:
If it's a maximum, it cannot go over a certain amount, but it does not say if it could be the same amount. so use ≤
