Second option, third option, and fifth option.
The regression analysis evaluates the amount of relationship that exists
between the variables in the analysis.
- The regression equation is;
- The prediction is worthwhile because it gives an idea of the observed Crash Fatality Rate and it is therefore approximately correct.
Reasons:
First part;
The given data is presented as follows;
![\begin{tabular}{|cc|c|}Lemon Imports (x) &&Crash Fatality Rate\\232&&16\\268&&15.7\\361&&15.4\\472&&15.5\\535&&15\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%7B%7Ccc%7Cc%7C%7DLemon%20Imports%20%28x%29%20%26%26Crash%20Fatality%20Rate%5C%5C232%26%2616%5C%5C268%26%2615.7%5C%5C361%26%2615.4%5C%5C472%26%2615.5%5C%5C535%26%2615%5Cend%7Barray%7D%5Cright%5D)
The least squares regression equation is; 
Where;
= The mean crash fatality = 15.52
= The mean lemon import = 373.6
Therefore;
c = - b· = 15.52 - (-0.00255)×373.6 = 16.47268
Therefore;
- The regression equation is
Second part;
When the imports is 425 metric tons of lemon, we have;
= -0.00255 × 425 + 16.47268 = 15.38893 ≈ 15.4
Therefore;
When the import is 425 metric tons, the Crash Fatality Rate ≈ 15.4
Given that the predicted value is between the values for 268 and 535, we
have that the prediction is approximately correct or worthwhile
<u>The prediction is worthwhile</u>

You are asked to do this problem by graphing, which would be hard to do over the Internet unless you can do your drawing on paper and share the resulting image by uploading it to Brainly.
If this were homework or a test, you'd get full credit only if you follow the directions given.
If <span>The points(0,2) and (4,-10) lie on the same line, their slope is m = (2+10)/(-4), or m =-3. Thus, the equation of this line is y-2 = -3x, or y = -3x + 2.
If </span><span>points (-5,-3) and (2,11) lie on another line, the slope of this line is:
m = 14/7 = 2. Thus, the equation of the line is y-11 = 2(x-2), or y = 11+2x -4, or y = 2x + 7.
Where do the 2 lines intersect? Set the 2 equations equal to one another and solve for x:
</span>y = -3x + 2 = y = 2x + 7. Then 5x = 5, and x=1.
Subst. 1 for x in y = 2x + 7, we get y = 2(1) + 7 = 9.
That results in the point of intersection (2,9).
Doing this problem by graphing, on a calculator, produces a different result: (-1,5), which matches D.
I'd suggest you find and graph both lines yourself to verify this. If you want, see whether you can find the mistake in my calculations.
13/15 of her allowance was spent in total.
To solve this, you'd need to find the least common denominator (LCD) so that both fractions have the same number on the bottom. In this case, the first number that you could get with 5 and 3 was 15.
Next, you'd have to multiply the numerator by the same amount as the denominator, so that the fractions are proportionate. So, for 1/5, since we had to multiply 5 by 3 to get 15, we'd multiply 1 by 3 as well, giving us 3/15. Doing the same with 2/3, we'd get 10/15.
Then, you add the two fractions together (10/15 + 3/15 = 13/15).
Now, in any other case, you could probably simplify the fraction after you've solved the problem. If we got 12/15 instead of 13/15, then we could simplify that to 4/5, since both 12 and 15 are divisible by 3. But in this case, this is the simplest form of that fraction.
Hope this helped!!!
7:20 sorry if not right in a rush
also will ask that you rate this and not just take the answer
