Answer:

The second answer, and possibly the first answer as also true.

She did run a test that would indicate its an unbalanced dice, but this wasn't tried out with a different person throwing the dice.

Step-by-step explanation:

This is because from the computer generator results we see 11 of the 25 values are estimating at 1/5 when we know dice are 1/6 and more than 1/2 show just under 1/5 which balances this to be 1/6

But there are 9/25 tests that showed values under 10 throws found a 6 in 9/25 events = 1/3 approx out of 1/10 of the throws, and 1/3 is still a higher value than 1/6 of the multiple throws so indicates 100 throws would not be enough to tell as we cannot possibly assume her results are comparable with a computer generator.As the computer generator completed 25 x 100 throws and have just compared only x10 in relation to 1/10 of the events of the generated computer.  This showing 9 of the 25 (100) throw events in relation scores 1/3 of the results a 6. The answer is she would need to throw somewhere between 1000 and 3000 to compare to the computers results.

A sensitive measuring device is calibrated so that errors in the measurements it provides are normally distributed with mean 0 a
Artemon [7]

Answer: 0.9660

Step-by-step explanation:

Given: Mean : \mu =0

Variance : \sigma^2=2.00

⇒ Standard deviation : \sigma = \sqrt{2}

The formula to calculate z is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= -3

z=\dfrac{-3-0}{\sqrt{2}}=-2.12132034356\approx-2.12

The P Value =P(z

For x= 3

The P Value =P(z

\text{Now, }P(-3

Hence, the probability that a given error will be between -3 and 3=0.9660

kupik [55]

2 \frac{1}{3} cups of flour

We require to find \frac{2}{3} of 3 \frac{1}{2}

change the mixed number to an improper fraction and of to multiply

3 \frac{1}{2} = \frac{7}{2}

\frac{2}{3} × \frac{7}{2}

= \frac{2(7)}{3(2)} = \frac{14}{6} = \frac{7}{3} = 2 \frac{1}{3}
