Answer:
b=41
Step-by-step explanation:
180=19v-41+(180-(20v+39))+17v
v=5
180=19v-41+b+17v
180=19(5)-41+b+17(5)
b=41
You first work out the mean then for each number subtract the mean and square the result then work out the mean of those squared differences and take the square rot of that and you're done :)
What toll how is that a question
Answer: Domain of function is or (0, )
Step-by-step explanation:
Assuming x as width of rectangle
so, Width = x
Question says, Length is 5in more than 3 times id width.
we write as Length = 3x+5
Therefore, Area of rectangle will be given function f(x)
f(x) = x(3x+5)
Here, It is important to notice that width and length of rectangle will always be positive values and also, area of rectangle is always positive.
we can write in equation as
Thus, Domain of function is or (0, )
Answer: B
