Jorge finish 1/4 of a level of his computer game in 1/3 of the air at this rate how many hours will it take to complete one leve
aliya0001 [1]
To solve this, we'd need an answer with a whole level, which means we'll multiply everything by 4. This would mean that 1/3 is also multiplied by 4, making 4/3. Which means a whole level is made in 4/3 hours or 1 1/3 hours.

At the Canada Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The
kondaur [170]

Answer:

a) 54 mph to 144 mph

Step-by-step explanation:

We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

At least eight-ninths of the player's serves.

8/9 is approximately 89%

So

Mean: 99, standard deviation: 15

99 - 3*15 = 54

99 + 3*15 = 144

So the correct answer is:

a) 54 mph to 144 mph
