Answer: 
Explanation:
The area of a triangle A can be calculated as A=(height)x(base)/2
We know the height is 6x.
We know 
So the equation becomes (using |AC| as the base length):

The base is 
THis will be the coordinates of the point at a turning point on the graph.
Since the second derivative is positive (=1) it will be a minimum value of f(x).
Answer: Yes , it is unusual for a boiler to weigh more than 1550 grams .
Step-by-step explanation:
Given : Big chickens: According to a poultry industry news website, the weights of broilers (commercially raised chickens) are approximately normally distributed with mean
1358 grams and standard deviation
161 grams.
When the probability that broiler weigh more than 1550 grams < 0.5 , then is unusual otherwise not.
Let x denotes the weight of broiler, then the probability that broiler weigh more than 1550 grams :-
Since 0.117<0.5
Therefore, it is unusual for a boiler to weigh more than 1550 grams .
