Mathematics

Damm [24]3 years ago
3 0

The axis of symmetry of a parabola is the vertical line passing through its vertex. Given a parabola ax^2+bx+c=0, the vertex x-coordinate can be found using

x = -\dfrac{b}{2a}

In your case, the formula leads to

x = -\dfrac{40}{10} = -4

So, this parabola is symmetric with respect to the line  x = -4

Jason owns a small business selling bagels. He knows that in the last week 45 customers paid cash, 8 customers used a debit card
tatuchka [14]

The probability that the next customer will pay with cash is 0.76

<h3>What is the probability?</h3>

Formula to find the probability of an event is:

P(A) = n(A)/n(S)

where;

n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment/survey

We are given that;

45 customers paid cash

8 customers used a debit card

6 customers used a credit card.

Thus, the total number of customers:

n(S) = 45 + 8 + 6

n(S) = 59

Let event A be the event that the next customer will pay with cash. Thus, n(A) = 45

Therefore, the probability that the next customer will pay with cash would be;

P(A) = n(A)/n(S)

P(A) = 45/59

P(A) = 0.76
