3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111
15z - 21 + 18z - 22 = 32z - 28 - 111
33z - 43 = 32z - 139
33z - 32z = -139 + 43
z = - 96

Hey there, Lets solve this together.

$3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111

15z - 21 + 18z - 22 = 32z - 28 - 111

33z - 43 = 32z - 139

33z - 32z = -139 + 43

z = - 96$

Explain how to graph the given piecewise-defined

Pavlova-9 [17]

The Piecewise -Defined function and how it is graphed is given below..

<h3>What is the explanation of how the Piecewise -Defined function is graphed?</h3>

Given the function in the attached image,

The Graph of f(x) = -x + 3 is drawn for x less than 2 because x is bounded.

The Graph of f(x) = 3 is draw for x greater than and equal to 2 and less than 4 because x is bounded.

The Graph of f(x) = 4 - 2x is draw for x greater than equal to 4 because x is bounded.

See the attached Graph for better understanding.

f(x) = -x + 3 is coded purple.
f(x) = 3 is coded orange.
f(x) = 4 - 2x is coded green.

Find the equation of the circle that passes through the point (-3,1) and has its center at C(-4,6)

qaws [65]

Answer:

(x+4)^2 + (y-6)^2 = 29

Step-by-step explanation:

The center-radius form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k)

Replacing the center C(-4,6):

(x+4)^2 + (y-6)^2 = r^2

then replacing the point (-3,1):

(-3+4)^2 + (1-6)^2 = r^2

1 + 25 = r^2

then the equation of the circle is:

(x+4)^2 + (y-6)^2 = 29

The mean time from prescription drop-off to medicine pickup for a customer served at Heisenberg's Pharmacy is 64 minutes, with a

kari74 [83]

Answer: B. 0.4772

Step-by-step explanation:

Given : The mean time : $\mu=64\text{ minutes}$

Standard deviation : $\sigma=18\text{minutes}$

Let X be the service time of a randomly selected customer.

Assuming a normal distribution, the value of z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 64

$z=\dfrac{64-64}{18}=0$

For x = 100

$z=\dfrac{100-64}{18}=2$

The p-value = $P(64$

$P(z$

Hence, the probability that a randomly chosen customer experiences service done between 64 and 100 minutes = 0.4772
