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 = \frac{\text{Sum of all observations}}{\text{No. of observations}}

Mean =\frac{338+160+210+180+166+272+.........+233+198}{24}

Mean =241.75

\text{Standard deviation} = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}}

Standard deviation = \sqrt{\frac{(338-241.75)^{2}+(160-241.75)^{2}+......+(185-241.75)^{2}+(233-241.75)^{2}+(198-241.75)^{2}}{24-1}}

Standard deviation =86.63

Range within 1 standard deviation :(\mu-\sigma,\mu+\sigma)

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

How do you solve it
EleoNora [17]
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

Triangles DEF and D'E'F' are shown on the coordinate plane below:
Lorico [155]

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.
