0 isn't one of them. There are 5 altogether. That comes from 7x^5. The 5 determines how many roots will solve the polynomial.
1 won't work either. Nor will minus 1. Both leave remainders. The only way to get started is to do this by brute force. Go down the list and see who gives a zero.
According to this graph, none of them work. There is one solution and it is marked on the graph. The 1 solution is just larger than -1. Check the question again and if it is different, put a comment at the bottom.
Answer:
B. 203.403
Step-by-step explanation:
2 times 100 = 200
3 times 1 = 3
4 times 1/10 = 0.4
3 times 1/1000 = 0.003
200 + 3 = 203
203 + 0.4 = 203.4
203.4 + 0.003 = 203.403
Answer: 194
Step-by-step explanation:
1. Square both sides to get (b+2)=14^2=196
2. Subtract 2 from both sides to get b=194
Answer:
w = -1/3
Step-by-step explanation:
3w = -6w - 12/4
(divide)
3w = -6w - 3
(Subtract -6w from both sides, aka add since its two negatives)
9w = -3
(divide both sides by 9)
w = -3/9
(simplify fraction)
w = -1/3
Answer:
The confidence interval for the population mean μ is
Step-by-step explanation:
Given :
Number of weights of newborn girls n=185.
Mean hg
Standard deviation s=7.5 hg
Use a 95% confidence level i.e. cl=0.95
To find : What is the confidence interval for the population mean μ?
Solution :
Using t-distribution,
The degree of freedom
The t critical value is t=1.973.
The confidence interval build is
Substitute the values,
Therefore, the confidence interval for the population mean μ is
