This is easily (A) Positive Association
Answer:
Step-by-step explanation:
Let the length of rectangle A be x units.
So, length of rectangle B
= x + 25% of x
= x + 0.25x
= 1.25x
Let the width of rectangle A be y units
So, Width of rectangle B
Area of rectangle A = xy
Area of rectangle B
= 1.25x * 0.6y
= 0.75xy

Hi there!
If any term, no matter what the number multiplied by zero will always turn out to be zero. I can give you an example of why this is correct.
We'll use apples. :P
If we have four apples multiplied by zero, you'd have zero apple because there's NO groups of apples to use.
Two times three is six because there are two groups of three, or three groups of two. But since earlier we said that there were zero groups of apples, there is zero groups of four so that cancels out to make none.
Hope this helps! :D
Answer: $375
Step-by-step explanation:
Given : The probability of winning $100 : P(100)= 0.25
The probability of winning $200 : P(200)= 0.50
The probability of winning $1000 : P(1000)= 0.25
Now, the the expected value of that lottery ticket is given by :-

Hence, the the expected value of that lottery ticket =$375
Answer:
(−∞,+∞)
Step-by-step explanation:
The cotangent function can take up any values depending on the value of
x
, the independent variable.
And thus, the range
(
−
∞
,
+
∞
)
is justified.
The domain is all real numbers other than integral multiples of
π
where, the function is not defined.
