For this, we need to find the lowest common multiple of 12 and 15....
common multiples of 12 : 12,24,36,48,60
common multiples of 15 : 15,30,45,60
LCM = 60
the caller that will be the first to win both is the 60th caller
4065323 × 10 to the senventh power?
Answer:
The <em>t</em>-value used for the 95% confidence interval of paired data is 2.776.
Step-by-step explanation:
The confidence interval formula for mean difference for a paired data is as follows:
Here,
= sample mean of the difference,
= sample standard deviation of the difference,
<em>n </em>= sample size (both samples are of same size).
= critical value of <em>t</em>
(<em>n</em> - 1) = degrees of freedom
The information provided is:
<em>n</em> = 5
Confidence level = 95%
The critical value of <em>t</em> is:
*Use a <em>t</em>-table for the critical value of <em>t</em>.
Thus, the <em>t</em>-value used for the 95% confidence interval of paired data is 2.776.
Answer:
D. It is the product of the initial amount and the decay factor after w weeks.
Step-by-step explanation:
We are told that Ariana starts with 100 milligrams of the substance. The number 100 in the expression likely represents this amount, <em>the initial amount</em>. It is multiplied by another number, so is part of a product. (It is not part of a difference, and is not something that is raised to a power.)
The factor (1 -0.2) represents the fraction remaining at the end of a week. That number raised to the power w will represent the fraction remaining at the end of w weeks. This fraction can reasonably be referred to as "the decay factor after w weeks."
Hence, the expression represents ...
<em>the product of the initial amount and the decay factor after w weeks</em>
