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:
32 i think
Step-by-step explanation:
its 16 cm, so 2 full rotations would be 16 times 2
which is 32
y = - 4x - 2
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 4x - 5 is in this form
with slope m = - 4
• Parallel lines have equal slopes
y = - 4x + c ← is the partial equation
To find c substitute (- 2, 6 ) into the partial equation
6 = 8 + c ⇒ c = 6 - 8 = - 2
y = - 4x - 2 ← equation of parallel line
Answer:
Step-by-step explanation:
we have that
h(t) = –16t² + 14t
using a graph tool
see the attached figure
the cricket’s hang time is the difference between point (0,0) and (0.875,0)
(0.875-0)=0.875 sec
the answer is 0.875 sec
We can simplify 15/3 to 5.
N/6 = 5. Then multiply both sides of the equation by 6, giving us N = 30.
