Answer:
Yes, snow and cold weather are independent.
Step-by-step explanation:
We are given the following in the question:
C: Cold weather
S: Snow
P(C) = 0.50
P(S) =0.30
We have to check whether snow and cold whether are independent events.
If the events A and B are independent then,
Checking,
Thus, the two events are independent.
For mutually exclusive events
Thus, the given events are not mutually exclusive.
Answer:
Step-by-step explanation:
Metacognition's best definition can be described as an awareness and understanding of one's own thought processes. Answer A is obviously the incorrect choice as it refers to English, not psychology. Answer choice B makes sense as those who understand their own thought processes may be good test takers. Answer choice C is about learning new things which I would say does not necessarily apply to understanding what you know. It is about new knowledge whereas metacognition is about old knowledge. The final answer choice, D, does not apply since metacognition is not a process, but an awareness. I would say that the most applicable answer choice is B.
Hope that helps!

The polynomial function with the given properties is; y = 2(x - 3)³(x + 4)²
<h3>How to construct polynomial functions?</h3>
Polynomials are defined as algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.
We need to form a polynomial expression with the following properties;
fifth-degree, 3 is a zero of multiplicity 3, −4 is the only other zero and ,the leading coefficient is 3. Thus, the polynomial will be;
y = 2(x - 3)³(x + 4)²

(t-1)(t+1) = t^2-1 through the difference of squares rule
So,
(t-1)(t+1)(t^2+1)
(t^2-1)(t^2+1)
(x-1)(x+1) ... let x = t^2
x^2-1 .... another application of the difference of squares rule
(t^2)^2 - 1... plug in x = t^2
t^4 - 1
