THe correct option is the 3rd option
Answer:
The scale factor used is 0.4
Step-by-step explanation:
Given
Required
Determine the scale factor of RST
The question can be solved using scale factor formula
Scale factor is calculated as thus;
In this case; R' is the new length and R is the old length
Substitute the values of R and R'
Factorize the denominator
<em>Hence, the scale factor used is 0.4</em>
An absolute value inequality to find the range of SAT mathematics test scores within one standard deviation of the mean is; |x – 515| ≤ 114
<h3>How to Write Inequalities?</h3>
A) We are told that;
Mean score = 515
Standard deviation = 114
We are now given that people within one deviation of the mean have SAT math scores that are no more than 114 points higher or 114 points lower than the mean. Thus, the absolute value inequality is;
|x – 515| ≤ 114
B) The range of scores to within ±2 standard deviations of the mean is;
Range = 515 ± 2(114)
Range = 287 to 743

The difference between abs extreme values (absolute extreme values) and extreme values is:
The absolute extreme values<span>, or </span>extrema<span>, refer to the </span>maximum<span> and minimum </span>values of a function while a<span>n </span>extreme value<span>, or </span>extremum<span> (plural </span>extrema<span>), is the smallest (minimum) or largest (maximum) value of a function.</span>
>A function f is said to have an
absolute maximum on an interval I at x0
if f(x0
) is the largest value of f on I; that is,
f(x0
) ≥ f(x) for all x in the domain of f that
are in I.
None of the above is true
