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)

$\frac{9}{14}$

Answer: $x=\frac{35±\sqrt[]{6505} }{22}$

Step-by-step explanation: $x=5.25698091…,−2.07516273…$

The roots ( $zeros$ ) are the $x$ values where the graph intersects the x-axis. To find the roots ( $zeros$ ), replace $y$ with $0$ and solve for $x$ .
