Answer:
Step-by-step explanation:
The sum of angles in a triangle is 180°, so angle x is the complement of the one marked 31°.
x = 90 -31
x = 59
__
The tangent relation tells you ...
tan(31°) = 10/y
y = 10/tan(31°) = 10/0.6009
y ≈ 16.64
__
The sine relation tells you ...
sin(31°) = 10/z
z = 10/sin(31°) = 10/0.5150
z ≈ 19.42
Answer:
-3
Step-by-step explanation:
(-2)^-3 x (-24)
(-2)^3 becomes 1/(-2)^3 in order to make the negative exponent a positive one.
then, you do 1/-8 (the -8 is the (-2)^3 simplified) x -24
1/-8 x (24) = 24/-8 = -3.
Hope this helps! :)
We all know about the bell curve i.e. normal distribution curve. It is centered about the mean and spread equally on each side.
We describe the area of the curve with the help of standard deviations.
With in 1 standard deviation about the mean i.e. from -1 s.d. (left of mean) to +1 s.d. (right of mean), it covers 68% of the total area of curve.
So, the data that falls outside 1 standard deviation of the mean would be equal to (100% - 68%) i.e. 32%.
So, 32% is the final answer.
