<h3>
Answer:</h3>
D. hypotenuse/opposite
<h3>
Step-by-step explanation:</h3>
The mnemonic SOH CAH TOA reminds you that ...
Sin = Opposite/Hypotenuse
You know that
csc = 1/sin
so
csc = 1/(opposite/hypotenuse) = hypotenuse/opposite . . . . matches D
Answer:
9
Step-by-step explanation:
The mean squared error (MSE)of a set of observations can be calculated using the formula :
(1/n)Σ(Actual values - predicted values)^2
Where n = number of observations
Steps :
Error values of each observation (difference between actual and predicted values) is squared.
Step 2:
The squared values are summed
Step 3:
The summation is the divided by the number of observations
The difference between the actual and predicted values is known as the ERROR.
(1/n)Σ(ERROR)^2
n = 3
Error = +3, +3, - 3
MSE = (1/3)Σ[(3)^2 + (3)^2 + (-3)^2]
MSE = (1/3) × [9 + 9 + 9]
MSE = (1/3) × 27
MSE = 9

Answer:
height = 9.28m
Step-by-step explanation:
Sum of angle in a triangle = 180°
To find the third angle, we have
180° = 71° + 62° + α
180° = 133° + α
α = 180° - 133°
α = 47°
To find the height use sine rule
h/sin47° = 12/sin 71°
h(sin71°) = 12sin47°
h = 12sin47° / sin71°
h = 12(0.7314) / 0.9455
h = 8.7768/0.9455
h = 9.28m
The distance formula is used to find the distance between two points in the coordinate plane. The point that is at the same distance from two points A and B on a line is called the midpoint. You calculate the midpoint using the midpoint formula.
