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
The answer is 100 percent B
4 2/3 is equal to 4 8/12. 3 and 1/4 is equal to 3 3/12. 4 8/12- 3 3/12 = 1 5/12. 1 1/2 would be a better estimate.
100<28+12d
If she wants to collect over 100 then the 100 would be less than (<) what she collects. She is starting with 28 so whatever she collects is added on. Because she collects 12 a day, you would multiply 12 by however many days, d, she collects.
He already walked the dog 5x which means he has $40 so far if he wants to get $88, just subtract $40 from $88. it will equal 48 then you divide it by 8 and your answer is you need to walk the dog 6 more times
