Consider in triangle as given below:
sin(A) = opposite/hypotenuse = BC/AC
cos(B) = adjacent/hypotenuse = BC/AC
<span>Now, both of them have the same hypotenuse and both will be equal. As you have seen already both the values are same.
</span>Thus, the <span>relationship between the sine of an angle and cosine of the other acute angle in the same triangle is shown below. And this ill this be true every time.</span>
Answer:
D) The z-statistics would be different.
Step-by-step explanation:
Confidence Interval can be calculated using M±ME where
- M is the sample mean
- ME is the margin of error from the mean
An margin of error (ME) from the mean can be calculated using the formula
ME= where
- z is the corresponding z-statistic in the given confidence level
- s is the population standard deviation
If 95% and 98% confidence intervals were calculated from the same sample data, then M, s and N are same.
is called standard error. Since s and N are same the standard errors would also be same.
But, two tailed z-statistic for 95% confidence level is ≈1.96 where for 98% it is ≈2.33
Answer:
B. $36.39
Step-by-step explanation:
29.85x 1.06= $31.64 with sales tax.
31.64x 1.15= 36.39
