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
7. Easiest method is substitution. Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)
