Reduced to 12/10 when dividing both by 6. can be reduced further to 1 2/10 and even further to 1 1/5.
Answer:
Right isosceles triangle
Step-by-step explanation:
In Right isosceles triangle, two angles are acute and equal, while, the third angle is of 90°
<span>E[Y] = 0.4·1 + 0.3·2 + 0.2·3 + 0.1·4 = 2
E[1/Y] =0.4·1/1 + 0.3·1/2 + 0.2·1/3 + 0.1·1/4 = 0.4 + 0.15 + 0.0666 + 0.025?0.64
V[Y] =E[Y2]-E[Y]2= (0.4)·12+(0.3)·22+(0.2)·32+(0.1)·42-22= 0.4+1.2+1.8+1.6-4= 5-4 = 1</span>
Answer:
B. A cow of 5 years is predicted to produce 5.5 more gallons per week.
Step-by-step explanation:
Let 
, where 
is the age of the dairy cow, measured in years, and 
is the predicted milk production, measured in gallons per week.
Besides, we consider 
and 
, such that 
, we define the difference between predicted milk productions (
) below:
(1)
If we know that 
and 
, then the difference between predicted milk productions is:
That is, a cow of 5 years is predicted to produce 5.5 more gallons per week than a cow of 10 years. Hence, the right answer is B.
1/2bh
1/2b4 = 18
b4= 36
b= 9 yards
