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
yes.
25 percent discount means that the price of one watch is 45 dollars.
45 plus 45 is less than 100.
The value of output, h, when the input, x, is -18 for the given equation is 14

Solving an equation </h3>
From the given question, we are to determine the value of the output, h, when the input x is -18
The given equation written properly is
h = 17 + x/6
Now, to determine the value of output, h, we will put in the value of x into the equation
h= 17 + x/6
The given value of x is -18
Thus, putting the given value of x into the equation, we get
h= 17 + x/6
h= 17 + -18/6
h = 17 + -3
h = 17 - 3
NOTE: + × - = -
h = 14
∴ h is 14 when x is -18
Hence, the value of output, h, when the input, x, is -18 for the given equation is 14
