Answer:
The range within 1 standard deviation :155.12
,328.38
Step-by-step explanation:
Data: 338+160+210+180+166+272+128+409+240+250+160+300+340+200+194+132+202+180+420+380+325+185+233+198
Mean =241.75
Standard deviation = 
Standard deviation =86.63
Range within 1 standard deviation :
Range within 1 standard deviation :(241.75-86.63,241.75+86.63)
Range within 1 standard deviation :155.12
,328.38
Hence The range within 1 standard deviation :155.12
,328.38
The equation describes a linear relationship between x and y. It can be graphed as a straight line. There is nothing to solve until you assign a value to one of the variables, or require they satisfy some additional constraint.
If you want to express it as "y =", then divide by the coefficient of y.
.. y = (-6/5)x -3
.. y = -1.2x -3 . . . . . . in decimal form
The <em><u>correct answer</u></em> is:
90° clockwise
Explanation:
Comparing the image points to the pre-image points, we can see that in every ordered pair, x and y have been switched and x has been negated. Algebraically, this means (x, y)→(y, -x).
This is the same mapping that a 90° clockwise rotation performs, so that is our answer.
