Answer:
13 customers use to text,
10 customers use the Internet,
the probability that a randomly selected customer who is on plan B uses the phone most often to text is
Step-by-step explanation:
A phone company surveys a sample of current customers to determine if they use their phones most often to text or use the Internet.
Plan B:
13 customers use to text,
10 customers use the Internet,
23 customers in total.
The probability that a randomly selected customer who is on plan B uses the phone most often to text is
-9+x ?
I don’t know if this is the right answer
Let us assume the common ratio to be = x
then
4x + 13x = 85
17x = 85
x = 85/17
= 5
Then
The ratio will be = 4 * 5:13 * 5
= 20:65
So the ration in which the number 85 can be separated is 20:65. i hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without taking any help from outside. Only be careful while calculating.
Well, you can actually go to the bank and they'll help you determine your interest rate. Whether you get a fixed interest rate, which means that if you pick 7% interest for twenty years, then your interest rate won't go up or down. It will stay at 7%. Or you can let your bank pick your interest rate. But they'll most likely pick the lowest rate they can.
