Answer:

-2(x^2+15)

Step-by-step explanation:

f(x) = −2(x − 4)^2 + 2.

Expanding (x-4)^2

(x-4)(x+4)

x(x+4)-4(x+4)

x^2+4x-4x-16

x^2-16

F(x) = -2(x^2-16)+2

-2x^2-32+2

-2x^2-30

-2(x^2+15)

faust18 [17]

Answer:

0.2196

Step-by-step explanation:

Given that

Mean = 4.56 million visitors per day

Standard deviation = 820,000 visitors per day

According to the given situation the calculation of probability is shown below:-

Here we will find the value of P (3 ≤ X ≤ 4)  

P 93\leq X\leq 4)=P(X\leq 4) - P(X\leq 3)

\\=P(\frac{X-\mu}{\sigma}\leq  \frac{4-4.56}{0.82})-P(\frac{X-\mu}{\sigma}\leq  \frac{3-4.56}{0.82})

\\=P(Z\leq -0.683)-P(Z\leq -1.9024

= 0.2483 - 0.0287

= 0.2196

Therefore the probability that the web site has between 3 million and 4 million visitors in a single day is 0.2196
