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 .

y-intercept = 7.
Answer:
Here the correct option is "b"
Step-by-step explanation:
First we need to understand the term "petty cash". As the name itself indicates that the petty cash box is maintained for petty cash expenditures. So it does not need heavy funds rather it accomodates payments for a relatively smaller expenditure which are paid in day to day expenses.
So, from the given options, Option "b" is the right option which exactly states that the journal entry to reflect replenishment would include "a debit to cash for $318" as the petty cash is maintained as a separate entity than the cash book so its transcitions are set down individually.
(C) "serpentine"
Serpentine is a winding word. The phrase would read "The mountain road was distinctly serpentine: it twisted back and forth along the contours of the hillside" if this term were added to the text.
The comma denotes that the meaning of the omitted phrase will be clarified in the second clause of the sentence. Because a winding road does actually curve "back and forth," the word "serpentine" matches the text. The answer is not (A).
A panoramic view is one that encompasses the entire surrounding region. (B) is the wrong answer. Precipitous refers to a steep slope. The answer is not (D). The term "circumscribed" describes something that is restrained or encircled by a line. The answer is not (E). Moving backward is referred to as retrograding.
