By the empirical rule, 84% of the distribution is below one standard deviation above the mean.
16% of Ed's monthly phone bills are more than $76.
In the number 16.83231, the bolded number is in the hundredths place.
Look to the number to the right of it (the thousands place value).
it is a 2, which is less than 5. Because of this, round down.
16.83 is your answer
hope this helps
Answer:
Rs 253.13
Step-by-step explanation:
The item cost him x.
Selling at a profit of 20% means he sold it for 1.2x.
Selling at a loss of 12% means that he sold it for 0.88x.
1.2x - 81 = 0.88x
1.2x - 0.88x = 81
0.32x = 81
x = 253.13
I believe just 1 because an equilateral triangle can only be reflected on one line for the halves to be the same
Given that:
5π/3
=5/3×180
=240°
This is in the Quadrant III
The value of cot 5π/3 will be given by:
cost θ=1/tan θ
thus
tan θ
=tan 5π/3
=tan 240
=tan (240-180)
=tan 60
using an equilateral triangle with lengths 2 units
then
tan 60=√3/1
tan 60=√3
hence
tan 240=√3
