Answer:
- <u><em>D. No, because $100,000 is much greater than the values used in the experiment.</em></u>
<u><em></em></u>
Explanation:
<em>Correlations</em>, when have strong correlation coefficients, which r = 0.9 is, may be good predictors within the limits of the range of the data.
Trying to extrapolate the <em>linear relationship</em> between the variables, <em>x = advertising spending and y= product sales</em>, way beyond the limits of the data used for the study, is too risky, because the data may be linear just for some stages (ranges) but behave very different in other ranges.
As, the option D. states, <em>$100,000 is much greater that the values used in the experiment</em>; hence, the correlation would likely would not be a good predictor for that input.
Answer:Ben
Explanation:bc ben loves me and u
We are able to make this easier by turning 25% into the fraction 1/4
1/4 * 162.5
Utilize the equation: a * ( b / c ) = ( ( a * b ) / c )
1 * 162.5 / 4 = 162.5 / 4
If you solve the above you get the quotient of 40.625
The alternative is to multiply 0.25 by 162.5 which will also yield the answer of 40.625
Remember 100% = 1.0, and 25% = 0.25 you can convert between percentages, decimals, and fractions to make solving these problems easier.
Converting to percentage is simply a% = ( a / 100 )
Answer:
1) The angle would be 150 degrees
a) coordinates would be ( , )
b) Trigonometric ratios:
sin:
cos:
tan:
csc: 2,
sec:
cot:
Explanation:
simplifys to which has a reference angle of . We can take the coordinates of and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin
