What is the center and radius of the circle with equation (x - 2)^2 + (y - 5)^2 = 100?

ololo11 [35]

Answer:
Center = (2,5)
Radius = 10
Choice A

To find this answer, first write the equation
(x-2)^2 + (y-5)^2 = 100
into
(x-2)^2 + (y-5)^2 = 10^2

Note how the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

We see that (h,k) = (2,5) is the center
and r = 10 is the radius

You are in charge of monitoring the pressure of a compressed air tank in a processing plant. After repeating the pressure measur

Anastasy [175]

Answer:

11.5

Step-by-step explanation:

Given that :

I am in charge of the pressure reading in a compressed air tank of a processing plant.

The Gaussian distribution having a mean value = 69 psi

Standard deviation = 10 psi

Here we have to find the probability that the pressure will exceed 84 psi.

So,

$P(X \geq 84) = P \left(\frac{X - 69}{10} > \frac{84-69}{10} \right)$

$=P(Z > 1.5)$

$=1-P(Z < 1.5)$

= 0.115

= 11.5
