Benny got $3.26 back from his purchase
Answer:
The probability that the next customer will purchase a wireless phone is 0.1
Step-by-step explanation:
The relative frequency approach states<em> how often something happens divided by all outcomes</em>.
In the example some of the customers entering a supermarket purchased a wireless phone.
Here all outcomes are 500 customer entering supermarket. And among these outcome purchasing wireless phone happened 50 times.
Then the probability that the next customer will purchase a wireless phone is
.
If we divide both sides by 50, we get
=0.1
Y = √(-x + 3)
Domain: x ≤ 3
y = √(3x)
<span>Domain: x ≥ 0</span>
Collect the like terms
3x+13x=16x
16x+8y
15 + 20 equals to 35, 60 - 35 equals to 25 so so his total journey is 1 hour
