Answer:

a) C. The random variable is discrete. The possible values are xequals​0, ​1, ​2,....

b) B. The random variable is continuous. The possible values are x greater than or equals 0.

Step-by-step explanation:

Discrete variables are countable in a finite amount of time. Continuous variables can be infinitely many. They rather assume values in a range.

<u><em>(a) Is the number of hits to a Web site in a day discrete or​ continuous? </em></u>

C. The random variable is discrete. The possible values are x equals​ 0, ​1, ​2,....

<u><em>(b) Is the weight of a Upper T dash bone steak discrete or​ continuous?</em></u>

B. The random variable is continuous. The possible values are x greater than or equals 0.

you make two cylinders using 8.5-by-11-inch pieces of paper. One has a height of 8.5 inches, and the other has a height of 11 in
Elan Coil [88]
The second cylinder is taller correct? 
8 in < 11 in 

If the height is also larger, the base is most likely larger too.

Wouldn't the largest cylinder have a Larger surface area?

NEED HELP ASAP I DONT GET THIS
denpristay [2]

Answer:

x = 60

Step-by-step explanation:

In a circle, the sum of the angles that meet at a point is 360 degrees. So now that we have the total, we can subtract all the given information in the picture. We have 84, 75, 68, and x + 73. Now let us set up and equation for this problem.

360 = 84 + 75 + 68 + x + 73

Now combine like terms.

360 = x + 300

Now subtract 300 on both sides.

x = 60

And this is the value of x.

The area of a square is 49 square meters. How long is each side?
Artemon [7]

A square has 4 equal sides, which means when you need to work out the area, you're doing length × width, but the length and width are exactly the same, because it's a square (look at the picture if you don't understand this).

That means you just have to pick any side (let's call this side x), and multiply it by another side of the square. Now, because all of the sides are equal, you're doing x multiplied by x, which is the same as x².

Therefore, if the area is equal to x², and in this question, it's also equal to 49 (as stated in the question), we can equate them to each other:

x² = 49

Now to get the x by itself, we need to do the opposite of squaring, which is square rooting. Therefore, we square root both sides of the equation:

√x² = √49

The √ and the ² cancel out, so you're just left with x:

x = √49

The square root of 49 is just 7, so we can replace √49 with 7, and we get:

x = 7

Now remember, earlier, I called x the value of one side. Therefore, by remembering that, you know that the value of one side is equal to 7. And because all the sides are the same as each other, each side is equal to 7 metres.

Therefore, your final answer is 7 metres :)
