Katarina tosses a thumbtack on the ground 202020 times to see if it lands on its side or if it lands with the point facing up (there are no other possible outcomes). Let S=S=S, equals the number of times it lands on its side. Is SSS a binomial variable? Why or why not? Choose 1 A
Each trial isn't being classified as a success or failure, so SSS is not a binomial variable.

(Choice B)
B
There is no fixed number of trials, so SSS is not a binomial variable.

(Choice C)
C
The trials are not independent, so SSS is not a binomial variable.

(Choice D)
D
This situation satisfies each of the conditions for a binomial variable, so SSS has a binomial distribution.

4.

step-by-step explanation:

it have the same area.brainliest

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

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)
