1 answer:
Answer:
19°
Step-by-step explanation:
You can form a right triangle using the given information. The height would be the opposite side of the triangle and the the distance between the tourist and the deer would be the adjacent side. To find the angle we can use the tangent
Tan x = opposite side / adjacent side
Tan x = 45/130
x = Tan^-1 (45/130)
x = 19°

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.
