Answer:
Sum of the interior angles = (n-2) x 180°
where
n is the number of sides of the polygon
Step-by-step explanation:
The formula for the sum of the interior angles of a polygon is:
where
is the sum of the interior angle of the polygon
is the number of polygons
Let's check the formula using an example:
We want to find the sum of the interior angles of a square, we know that a square has 4 sides, so .
Replacing values
We can apply the same procedure to any convex polygon with n sides.
Hi!
To compare this two sets of data, you need to use a t-student test:
You have the following data:
-Monday n1=16; <span>x̄1=59,4 mph; s1=3,7 mph
-Wednesday n2=20; </span>x̄2=56,3 mph; s2=4,4 mph
You need to calculate the statistical t, and compare it with the value from tables. If the value you obtained is bigger than the tabulated one, there is a statistically significant difference between the two samples.
To calculate the degrees of freedom you need to use the following equation:
≈34
The tabulated value at 0,05 level (using two-tails, as the distribution is normal) is 2,03. https://www.danielsoper.com/statcalc/calculator.aspx?id=10
So, as the calculated value is higher than the critical tabulated one,
we can conclude that the average speed for all vehicles was higher on Monday than on Wednesday.
(0.5 liter/bottle) x (6 bottles/pack) = 3 liters/pack
(10 days) x (1.5 liter/day) / (3 liter/pack) = <u>5 packs</u>
Answer:
the opposite of negative 3/5 [-3/5] is positive 3/5 [3/5].
Good luck.
I guess you mean 4/5 and 3/5
this is a right angled triangle with side 3-4-5 so 5 is the hypotenuse
sin x = opp / hyp = 4/5 so the opposite side is 4
cos x = adj/hyp = 3/5 so the adjacent side = 3
so tan x = opp/adj = 4/3
