Sin(-x) is equal to - sin(x)
Therefore, sin(-35) = -sin 35
Your answer is B.
A solution is an answer to a math question, so no this is not a solution
Answer:
x < 5
Step-by-step explanation:
Given that:
(x+4 over 2x-1)<0
It can be written as:
x + 4/2x-1 <0
Multiplying both sides by 2x -1
x+ 4 < 2x -1
By simplifying:
Take terms with x on left side and constants on right side:
x - 2x < -1 - 4
- x < -5
"-" sign will be cancelled from both sides
x < 5
i hope it will help You!
Answer:
And we are confident that the true mean for this case is given by
Step-by-step explanation:
Data given
represent the sample mean for the WBC
population mean
s=3.9265 represent the sample standard deviation
n=187 represent the sample size
Confidence interval
The confidence interval for the true mean is given by:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The degrees of freedom, are given by:
The Confidence level is 0.90 or 90%, the significance is and , the critical value for this case would be
Replacng into the formula we got:
And we are confident that the true mean for this case is given by
