Answer:
Part A) The zero's of the function are 
Part B) The solution set is the interval ![[0.84,7.16]](https://tex.z-dn.net/?f=%5B0.84%2C7.16%5D)
Step-by-step explanation:
we have
Using a graphing calculator
Part A) What are the zeros of the inequality to the nearest hundredth?
The zero's of the function are the values of x when the values of the function are equal to zero
see the attached figure
The zero's of the function are
Part B) What is the solution set for the inequality?
The solution set is the interval
All real numbers greater than or equal to 0.84 and less than or equal to 7.16
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: 15%
Step-by-step explanation:
They gave their server $8.79 and their total bill was $58.60.
The question wants to know how much percentage of the total bill the tip they gave is:
= Tip / Total bill * 100%
= 8.79 / 58.60 * 100%
= 15%
