A local shop prints photos. The function f(x) = −x2 + 20x − 75 models the profit from one customer, where x is the number of pho
AnnZ [28]

Answer:

x = 5, x = 15; The zeros represent the number of photos printed to produce a maximum profit.

Step-by-step explanation:

F(x) = −x²+ 20x − 75

Let's f(x)= 0

0= -x²+20x-75

0= x²-20x+75

0=x²-5x-15x+75

0= x(x-5)-15(x-5)

0= (x-5)(x-15)

The zeros are

X= 5 or x = 15

And the xeros represent a number of photos printed to produce maximum profit

LUCKY_DIMON [66]

The probability that the Geometry textbook will be first from the left and the Chemistry textbook will be second from the left is 1/30

<h3>How to determine the probability?</h3>

The distribution of the books is:

Spanish, English, Chemistry, Geometry, History, and Psychology

The probability of choosing a Geometry book is:

P(G) = 1/6

Now, there are 5 books left.

The probability of choosing a Chemistry book is:

P(C) = 1/5

The required probability is:

P = 1/6 * 1/5

Evaluate

P = 1/30

Hence, the probability is 1/30
