How I know: 36 x .15 (15% is .15 in decimal). Answer: 5.4
The confidence interval is based on
mean square error. T<span>he </span>mean squared error<span> (</span>MSE<span>) </span><span>of an </span>estimator<span> measures the </span>average<span> of the squares of the </span>errors<span> or </span>deviations.<span> MSE is calculated by the formula attached in the picture, where Xbar is a vector of predictions, X is the vector of predicted values. </span>
Assuming imaginary numbers aren't possible the answer would be
x < -3
otherwise
x not= -8 and 2
Answer:
Surface area of the cone = 360π in²
Step-by-step explanation:
Formula for the surface area of a cone is,
Surface area = πr(r + l)
Here 'r' = radius of the circular base of the cone
l = Lateral height of the cone
Now we substitute the values in the formula from the figure attached,
Surface area = π(10)(10 + 26)
= 360π in²
Therefore, surface area of the cone will be 360π in².
