It's not an irrational number because the decimal is repeating. If it went on forever and never repeated then it would be an irrational number.

I think the error is that Richie thought for a number to be irrational, it just needed to repeat forever.

Question:

Marina CMI [18]

Since 2x+y>4 you get y>4-2x. Then you draw the line y=4-2x then you are interested in everything above the line not including it since it is y>4-2x so it is a dashed line. You need to shade the side that satifies the inequality and since it is every pair (x,y) where y>4-2x, you need to shade everything above the line which is the side that does not include the origin. So the answer is C.

Given right triangle ABC. To the nearest degree, find the measure of angle B.

DedPeter [7]

Answer:

Step-by-step explanation:

We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.

sin(B) = side opposite / hypotenuse:

$sin(B)= \frac{ 4.8}{ 5.1}$ so

sin(B) = .9411764706

Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:

$sin^{-1 ($

Enter that decimal after the open parenthesis and hit "enter" to get

B = 70.25 or 70°

Answer: b) -0.625

<u>Step-by-step explanation:</u>

The formula for the z-score is:

$z=\dfrac{x-\mu}{\sigma}\\\\\bullet z \text{ is the z-score}\\\bullet x \text{ is the value}\\\bullet \mu \text{ is the mean}\\\bullet \sigma \text{ is the standard deviation}\\\\z=\dfrac{6-8}{3.2}\\\\\\.\ =\dfrac{-2}{3.2}\\\\\\.\ =\large\boxed{-.0625}$
