Answer:
I don't see the number line
Step-by-step explanation:
i would love to help you out, but I don't see the number line I'm supposed to be referencing.
The probability that has a basic model purchase extended warranty will be 0.1935 or 19.35%.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A company that manufactures video cameras produces a basic model and a deluxe model.
Over the past year, 45% of the cameras sold have been of the basic model.
Of those buying the basic model, 43% purchase an extended warranty, whereas 50% of all deluxe purchasers do so.
If you learn that a randomly selected purchaser has an extended warranty.
Then the probability that has a basic model purchase extended warranty will be
P = 0.45 × 0.43
P = 0.1935
P = 19.35%

QUESTION:
A battery was charged. When the charging began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent full. how fast did the battery charge and how long did it take?
Solution :
<u>Given</u>
- Initial amount of charge = 23%
- Amount after charge = 89%
<u>procedu</u><u>re</u>
Let the rate of charging be r .
r = (change in charge level) / (time interval) = (89% - 23%) / (30 min) = 2.2 % per minute
charge = (rate of charging)(time) + (initial charge)
100% = r*t + 23%
100% = (2.2 %/min)t + 23%
Solve for t and get
t = [(100 - 23) / 2.2]
Answer = 35 min
A whole number greater then 10 but less then 15 would be 12
