By definition the interquartile range or IQR is obtained when the 25th percentile or is subtracted from the 75th percentile or
.
Thus, from the above definition, the formula for IQR is:
As we can see from the provided options that the definition of IQR matches the expression provided in Option A and thus, Option A is the correct answer.
Answer:
7 ft
Step-by-step explanation:
Perimeter of a rectangle is denoted by the formula: , where l is the length and w is the width.
We know that P = 20 and that w = 3. So, let's plug these values in:
Isolate the variable by subtracting 6 from both sides and dividing by 2:
Thus, the answer is 7 feet.
Hope this helps!
Answer:
The answer is below
Step-by-step explanation:
Show that f(x) f(y) = f(x+y)
From trigonometric:
sin(x + y) = sinxcosy + cosxsiny
sin(x - y) = sinxcosy - cosxsiny
cos(x + y) = cosxcosy - sinxsiny
cos(x - y) = cosxcosy + sinxsiny
