Answer:
The value of m is 3
Step-by-step explanation:
we have
![x^{2}+mx+n=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2Bmx%2Bn%3D0)
step 1
Find the value of n
For x=0
![0^{2}+m(0)+n=0](https://tex.z-dn.net/?f=0%5E%7B2%7D%2Bm%280%29%2Bn%3D0)
![n=0](https://tex.z-dn.net/?f=n%3D0)
step 2
Find the value of m
For x=-3
substitute
![x^{2}+mx=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2Bmx%3D0)
![(-3)^{2}+m(-3)=0](https://tex.z-dn.net/?f=%28-3%29%5E%7B2%7D%2Bm%28-3%29%3D0)
![9-3m=0](https://tex.z-dn.net/?f=9-3m%3D0)
![3m=9](https://tex.z-dn.net/?f=3m%3D9)
![m=3](https://tex.z-dn.net/?f=m%3D3)
Answer:
x^8
Step-by-step explanation:
Whenever there is a (x^b)^a multiply a and b to get the exponent. :)
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 .
1) Reflexive, 2) possessive, 3) possessive, 4) possessive, 5)"that" should be underlined and it is a relative,6) reflexive,7)"who" is the pronoun and that is a relative,8) possessive.9)possessive, 10) is reflexive. I hope this helps
Can you take a more clearer picture thx
