Answer:

128, 512, and 2048

Step-by-step explanation:

When you look at the sequence already given, you can notice each value is being multiplied by 4:

2 x 4 = 8

8 x 4 = 32

Keep applying this rule to find the 4th, 5th, and 6th numbers:

32 x 4 = 128

128 x 4 = 512

512 x 4 = 2048

These are your answers

Hope this helps!

At the U.S. Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The st

Answer:

The speed of 65 mph is an outlier in the distribution of the player's serve speeds

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100 mph

Standard Deviation, σ = 10 mph

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Outlier on basis of z-score:

Any z-score greater than 3 or less than -3 is considered to be an outlier.
This rule of thumb is based on the empirical rule.

Calculation of z-score:

$x = 65\Rightarrow z = \dfrac{65-100}{10} = -3.5\\\\x = 110\Rightarrow z = \dfrac{110-100}{10} = 1\\\\x = 120\Rightarrow z = \dfrac{120-100}{10} = 2$

Thus, the speed of 65 mph is an outlier in the distribution of the player's serve speeds as the corresponding z-score is less than -3.

nydimaria [60]

Answer:

A) 33.3%

B) 50 %

Step-by-step explanation:

A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.

B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order
