A study of the relationship between age and various visual functions (such as acuity and depth perception) reported the following observations on area of scleral lamina (mm2) from human optic nerve heads.2.812.562.683.762.262.733.914 .313.874.253.384.612.463.622.753.56 2.97 (a) Calculate âxi and âxi2
(b) Use the values calculated in part (a) to compute the sample variance s2 and then the sample standard deviation.

stops on an even number.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

answer:

probably the same as it is today since you did not eat the corn dogs yet

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
