Common ratio is 5 or -5 to be more precise. 225 divides by 45=5 and 45 divided by 9=5. So the common ratio is 5.

First term of sequence, a1 = 225

next term, a2 = 45

$common \: ratio = \frac{a2}{a1} \\ \\ r = \frac{45}{225} \\ \\ r = \frac{1}{5}$

common ratio is 1/5.

Answer:

$\frac{9}{14} \ chance$

Step-by-step explanation:

1. Approach

Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, $\frac{desired\ outcomes}{total\ outcomes}$ .

It is given that

- (63) paid with cash

- (22) paid with a debit card

- (13) paid with a credit card

First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.

2. Find the total number of customers

Add up all of the given customers, regardless of their payment type.;

$(cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98$

(98) total customers.

3. Find the probability

Now set up the probability, remember, the formula for finding the probability is,

$\frac{desired\ outcomes}{total\ outcomes}$

The desired outcome is the number of customers who pay with cash = (63)

The total outcome is the number of customers who when to the business; (98)

Substitute in the numbers and simplify,

$\frac{desired\ outcomes}{total\ outcomes}$

$\frac{63}{98}$

Both of these numbers are divisible by (7), hence divide the fraction by (7)

$\frac{9}{14}$
