CD = BE so:-
5x + 1 = 6x - 2
-x = -3
x = 3
so CD = 5(3) + 1 = 16 answer
Answer:
Step-by-step explanation:
Total Frequency = 48 + 264 + 264 + 60 + 12= 648
The degrees represented for each are:
UK = 48 / 648 x 360 = 26.67 ( round it to 27)
Europe = 264/648 x 360 = 146.67 ( round to 146)
USA = 146.67 (round to 146)
Africa = 60/648 x 360 = 33.33 ( round to 33)
Other = 12/648 x 360 = 6.67 (round to 7)
Hope this Helps.
Cna you also check your numbers of frequency
Answer:
Step-by-step explanation:
The standard form of a quadratic is . You need to subtract the x^2 from the right to set the quadratic equal to 0. Then a,b, and c are equal to the values of the coefficients in front of the terms.

If there was a regression and correlational analysis where r² = 1 then we know that A. SSE must equal to zero.
<h3>What happens when r² is 1?</h3>
r² is called the coefficient of determination and when it has the value of 1 in a regression, it means that all the points on the graph fit on the line of best fit.
This means that there are no residual errors and because there are no errors, there will be no Sum of Squared Errors (SSE) which is derived from the residual error.
Options for this question are:
- A. SSE must equal to zero
- B. SSE can take on any negative or positive value
- C. SSE must be greater than SS Total
- D. SSE must be greater than one
