Answer:
The answer is Discrete Random Variable
Step-by-step explanation:
A random variable is considered discrete if its possible values are countable.
In our case,
In a basketball game, for example, it is only possible for a team's score to be a whole number—no fractions or decimals are allowed, and so the score is discrete.
A good rule of thumb is this: if the variable you're measuring has to be rounded before it's written down, then it's continuous. If no rounding is necessary, as with anything that's countable, then it's discrete.

Answer:
RM = 12 cm
Step-by-step explanation:
![a^{2} + b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
Assuming 20 is the hypotenuse cus there is no picture:
![a^{2} + 16^{2} = 20^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%2016%5E%7B2%7D%20%3D%2020%5E%7B2%7D)
![a^{2} +256 = 400](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B256%20%3D%20400)
![a^{2} = 144](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%3D%20144)
![a=144](https://tex.z-dn.net/?f=a%3D144)
If It's not the hypotenuse:
![16^{2}+ 20^{2} =c^{2}](https://tex.z-dn.net/?f=16%5E%7B2%7D%2B%2020%5E%7B2%7D%20%3Dc%5E%7B2%7D)
![256+400 =c^{2}](https://tex.z-dn.net/?f=256%2B400%20%3Dc%5E%7B2%7D)
![656=c^{2}](https://tex.z-dn.net/?f=656%3Dc%5E%7B2%7D)
![c = 25.61249695](https://tex.z-dn.net/?f=c%20%3D%2025.61249695)
But I find it unlikely that 20 wasn't the hypotenuse so ignore that unless it applies.
Hope this helped. :0)
Answer:
Height of the ball after 3 seconds = 27.4 feet.
Step-by-step explanation:
h(t) = -4.9t^2 + 22t + 5.5
h(3) means the height of the ball at time 3 seconds after the ball was thrown.
h(3) = -4.9(3)^2 + 22(3) + 5.5
= 27.4 feet
The first term is 2 and the 20th term is 1048576 .
<u>Step-by-step explanation:</u>
Here we have , If the sum of the first 12 terms of a geometric series is 8190 and the common ratio is 2. We need to Find the first term and the 20th term. Let's find out:
We know that Sum of a GP is :
⇒
So ,Sum of first 12 terms is :
⇒ ![S_1_2 = \frac{a(2^{12}-1)}{2-1}](https://tex.z-dn.net/?f=S_1_2%20%3D%20%5Cfrac%7Ba%282%5E%7B12%7D-1%29%7D%7B2-1%7D)
⇒ ![8190=a(2^{12}-1)](https://tex.z-dn.net/?f=8190%3Da%282%5E%7B12%7D-1%29)
⇒ ![\frac{8190}{4095}=a](https://tex.z-dn.net/?f=%5Cfrac%7B8190%7D%7B4095%7D%3Da)
⇒ ![a=2](https://tex.z-dn.net/?f=a%3D2)
Now , nth term of a GP is
⇒ ![a_n = ar^{n-1}](https://tex.z-dn.net/?f=a_n%20%3D%20ar%5E%7Bn-1%7D)
So , 20th term is :
⇒ ![a_2_0 = 2(2)^{20-1}](https://tex.z-dn.net/?f=a_2_0%20%3D%202%282%29%5E%7B20-1%7D)
⇒ ![a_2_0 = (2)^{20}](https://tex.z-dn.net/?f=a_2_0%20%3D%20%282%29%5E%7B20%7D)
⇒ ![a_2_0 = 1048576](https://tex.z-dn.net/?f=a_2_0%20%3D%201048576)
Therefore , the first term is 2 and the 20th term is 1048576 .
