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 :-
![P(x>1550)=1-P(x\leq1550)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{1550-1358}{161})\\\\\approx 1-P(z\leq1.19)\ \ [\because\ z=\dfrac{x-\mu}{\sigma}]\\\\=\\\\=1-0.8830\ \ [\text{By using z-table}]\\\\=0.117](https://tex.z-dn.net/?f=P%28x%3E1550%29%3D1-P%28x%5Cleq1550%29%5C%5C%5C%5C%3D1-P%28%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5Cleq%5Cdfrac%7B1550-1358%7D%7B161%7D%29%5C%5C%5C%5C%5Capprox%201-P%28z%5Cleq1.19%29%5C%20%5C%20%5B%5Cbecause%5C%20z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5D%5C%5C%5C%5C%3D%5C%5C%5C%5C%3D1-0.8830%5C%20%5C%20%5B%5Ctext%7BBy%20using%20z-table%7D%5D%5C%5C%5C%5C%3D0.117)
Since 0.117<0.5
Therefore, it is unusual for a boiler to weigh more than 1550 grams .
Answer is 210/39.37 metres because you divide by number of inches to get metres
Answer:
B(-7, -3) C(3, -3) D(3, -1) E(-7, -1)
Step-by-step explanation:
*I am just labeling the points*
B(-7, 5) C(3, 5) D(3, 7) E(-7, 7)
If we were to translate the points 8 units down, we would only need to subtract the y-intercept for every point by 8. (Except don’t include any tenth places)
B(-7, -3) C(3, -3) D(3, -1) E(-7, -1)
