Answer:

the cup will land on its side 310 times and it'll land on the end 55 times

Step-by-step explanation:

To determine the amount of times it lands on the side, take the days in a year, 365, and multiply that by .85, which gets you 310. To get the amount of times it lands on its end, just subtract 310 from 365.

Select the correct answer.
tatyana61 [14]

Answer:

The answer is the first choice, that the outcomes (getting a 2, 4, or 6 or getting a 1, 3, or 5) are equally likely because the frequencies are close.

Step-by-step explanation:

The second choice isn't true because there isn't a lot of variation. If there was, this would mean they aren't equally likely.

The third choice isn't true because it doesn't make a statement about why the odd/even identity of the sets should affect the likelihood. (Besides, we know they are equally likely.)

The fourth choice isn't true because there is not a lot of difference in the relative frequency.

Find the distance between (2, -75) and (10,235).
zmey [24]

Answer:

310.1

Step-by-step explanation:

Use the distance formula:

\sqrt{(10-2)^2+(235-(-75))^2}

Simplify inside the parentheses

\sqrt{(8)^2+(310)^2}

Simplify exponents

\sqrt{64+96,100}

Simplify by adding

\sqrt{96,164}

Simplify

\sqrt{96,164} =310.1

Done. B-)

New York State’s "Quick Draw" lottery moves right along. Players choose between one and ten numbers from the range 1 to 80; 20 w
Mrac [35]

Answer:

The Answer is 0,133484. The same number as (60/80)^7 or 0.75^7

Step-by-step explanation:

If the probability of an event occurring is <em>p</em>, then the probability of an event not occurring is <em>1-p</em>. Therefore if Lester plays one number, then the probability of that number not winning is 1-\frac{20}{80} or 1-0.25, which is \frac{60}{80} or 0.75

\\Two or more events are independent if the occurrence of one does not affect the probability of occurrence of the other. In Lester's game, the probability of a number winning or not winning does not affect the probability of the same number winning or not winning in the next game.

\\In order to find the probability of several events occurring in succession, we multiply the probabilities of the individual events.

\\Therefore if Lester plays one number seven times, the probability that all seven bets lose are (60/80)^7 or 0.75^7
