A college student recently purchased a multiplayer video game. Before playing, the college student looked up statistics on how fast gamers were completing the full playthrough of the game. Of the 500 players that have completed the game, 331 of them completed the full game in less than 49 minutes. Use Excel to determine the probability that in a sample of 45 games, 30 or fewer of them were completed in less than 49 minutes. Round your answers to two decimal places.

answer:

what is your question that you ask

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)
