Answer: option C is the correct answer.

Step-by-step explanation:

In a cube, all the sides are equal.

The cube shown is 2 centimeters on all sides. The diagonal forms a right angle triangle with the sides of the cube with the diagonal representing the hypotenuse of the right angle triangle.

To determine the diagonal of the face of the cube,y, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore

y² = 2² + 2² = 4 + 4

y² = 8

y =√8

To determine the diagonal of the cube, x,

x² = 2² + y²

x² = 2² + (√8)² = 4 + 8

x² = 12

x √12 = 3.5 cm rounded to the nearest tenth.

Answer:

2\sqrt{3} or 3.5 cm.

Step-by-step explanation:

Here we'll need a bit of right angle trig.

z^{2} + y^{2} = x^{2}, where x is the hypotenuse, and z and y are the opposite and adjacent sides. We can determine y by using the formula for the diagonal of a square, which is s\sqrt{2 }. So, y =  2\sqrt{2 } and z = 2.

Therefore, we see that x = \sqrt{(2\sqrt{2})^{2} + (2)^{2}  } = \sqrt{8+4} =\sqrt{12} = 2\sqrt{3}

Suppose the p-value is 0.1038. what is the correct interpretation of this p-value in context?
Basile [38]

The p value 0.1038 represent the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

According to the statement

we have given that the P value and we have to find the correct interpretation of this p-value in context.

So, For this purpose, we know that the

The P - Value is the In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed.

And in the given statement ,

The given p value is 0.1038.

And this p value is a If the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

So, The p value 0.1038 represent the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.
