Answer:
2 Independent Random Variables The random variables X and Y are said to be independent if for any two sets of real numbers A and B, (2.4) P(X 2 A;Y 2 B) = P(X 2 A)P(Y 2 B): Loosely speaking, X and Y are independent if knowing the value of one of the random variables

Answer:
12.8 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between angles and sides of a right triangle. Here, you have the side opposite the given 70° angle, and you want to find the hypotenuse. The appropriate relation is ...
Sin = Opposite/Hypotenuse
Solving for the hypotenuse, we get ...
Hypotenuse = Opposite/Sin
x = (12 cm)/sin(70°) ≈ 12.77 cm
x ≈ 12.8 cm

Greatest Integer Function,<span> denoted by </span>
![y = [x]](https://tex.z-dn.net/?f=y%20%3D%20%5Bx%5D)
<span>. For all real numbers, x, <em>the </em></span><em>greatest integer function</em><span><em> returns the largest </em></span><em>integer</em><span><em> less than or equal to x</em>. In essence, it rounds down a real number to the nearest </span>integer<span>.
a.
FALSE. Because f(4.9) will round down to
4.
b.
TRUE. c. no it's not the absolute value function. that has V-shape
d.
TRUE.
e. FALSE. because for every unique x-value you don't always get a unique y value. .... f(5)=5, f(5.1)=5, f(5.76)=5, etc.</span>
Answer:
d
Step-by-step explanation:
No, the residual plot does not show random scatter around the residual = 0.
