Answer:
7805.51312
Step-by-step explanation:
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>
Slope: (y2-y1)/(x2-x1)
(8-4)/(3-6) = 4/-3
The slope is -4/3
Answer:
midpoint is y2+y1/2, x2+x1/2 therefore 3+1/2,-6+-4/2,4/2,-10/2 and the answer is (2,-5 )
(9×6/2) × 12 = 324
Explination:
The easiest way to understand what you're doing is to find the area of the base first, then extend it upwards to find the volume using height. Hence the equation: b×h=v
So how do we find the base of a triange? Remember that every single triangle can be calculated as a square, then cut in half. So 9 × 6 / 2 = 27 cm2
The next step is to calculate the volume using the height of the figure. 27 × 12 = 324 cm3
**<em>remember to </em><em>use</em><em> </em><em>the</em><em> </em><em>correct</em><em> </em><em>units</em><em>,</em><em> </em><em>since</em><em> </em><em>area</em><em> </em><em>and</em><em> </em><em>volume</em><em> </em><em>are</em><em> </em><em>different</em><em>. </em>
