Multiplication is a way to represent repeated addition. ... Instead, we can write this repeated multiplication using an exponent, which is the number of repeated factors. Exponents are written as a superscript number to the right of the number being multiplied.
The values of the trigonometric ratio is 1/4 , √15 / 4 , 4 .
<h3>What are Trigonometric Ratios ?</h3>
When a Triangle is a right angled Triangle then the ratios used to determine the sides and the angles of the triangle are called Trigonometric Ratio.
It is given that in triangle EFG , right angled at F ,
EG = 8 , FG = 2
By Pythagoras theorem
The length of EF is
8² = 2² + EF²
EF = √(64-4) = √60 = 2√15
The value of the trigonometric ratios is
sin E = Perpendicular / Hypotenuse
sin E = 2 / 8 = 1/4
sin G = 2√15 / 8 = √15 / 4
sec G = 1 / cos G = Hypotenuse / Base = 8 / 2 = 4
Therefore the values of the trigonometric ratio is 1/4 , √15 / 4 , 4 .

In constructing 98% confidence intervals for means, it is true that the statistic is good enough, and is less uncertain.
<h3>What is a confidence interval?</h3>
A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.
Your level of confidence in your findings is shown by the confidence interval. You can never be certain that your results will hold for future surveys or experiments. In statistics, being 95% or 98.5% certain is typically seen as "good enough."

Answer:
13 years
Step-by-step explanation:
First we will have to see how much she owns her aunt:
800-448= 362
8% of 348 = 27.84
362 ÷ 27.84 = 13 years
I might be wrong but hopefully this helps :)
