This is an upper tail test, so we are only concerned about the critical value that gives an area of 0.05 in the upper tail. Any test statistic greater than or equal to this critical value will result in the null hypothesis being rejected. We previously determined that this test will use 13 degrees of freedom. Use technology to find the value of
2
that corresponds to an upper tail area of 0.05, rounding the result to three decimal places.
2 =

the answer is -1 for this question

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)
