(3) dan (4)

• D.

(1) dan (3)

• E.

(2) dan (4)

B. (2) dan (3)
Explanation
The correct answer is (2) and (3) because statement (2) states that AH and GE intersect, which means they share a common point. Statement (3) states that EC is perpendicular to the plane BDG, which means EC forms a right angle with the plane BDG. Both of these statements are true based on the given information about the cube ABCD.EFGH.

### Diketahui limas beraturan T.ABCD, panjang rusuk AB = 4 cm dan TA = 6 cm. Jarak titik B dan rusuk TD adalah . . . .

• A.

• B.

• C.

• D.

• E.

A.
Explanation
The distance between point B and edge TD can be calculated using the Pythagorean theorem. We can consider the right triangle BTD, where the hypotenuse is the distance we want to find. The length of edge TD is equal to the height of the pyramid, so we can use the formula for the height of a regular pyramid: h = (AB * sqrt(3)) / 3. Substituting the given values, we have h = (4 * sqrt(3)) / 3. Then, we can use the Pythagorean theorem to find the distance between B and TD: (distance)^2 = (h)^2 + (TA - TB)^2. Substituting the known values, we get (distance)^2 = ((4 * sqrt(3)) / 3)^2 + (6 - 4)^2. Simplifying this equation will give us the distance between B and TD.

### Perhatikan gambar kubus ABCD.EFGH. Jarak titik H ke DF adalah …

C.
Explanation
The distance between point H and DF can be calculated by finding the length of the diagonal of the face DHEF. This can be done using the Pythagorean theorem, which states that the square of the length of the diagonal is equal to the sum of the squares of the lengths of the two sides. In this case, the length of the diagonal DH can be found by taking the square root of the sum of the squares of the lengths of DE and EF.

C. 8
Explanation
The average of a set of numbers is found by summing all the numbers and dividing by the total number of values. In this case, the sum of the given numbers is 4 + 10 + 7 + x + 10 + 6 + 11. Since the average is given as 8, we can set up the equation (4 + 10 + 7 + x + 10 + 6 + 11) / 8 = 8. Simplifying this equation, we get (48 + x) / 8 = 8. Solving for x, we find that x = 4. Therefore, the correct answer is 4.

Explanation
The interquartile range is a measure of the spread or dispersion of a dataset. It is calculated by finding the difference between the upper quartile (Q3) and the lower quartile (Q1). In this case, the lower quartile is 9 and the upper quartile is 14. Therefore, the interquartile range is 14 - 9 = 5.

C. 2
Explanation
The correct answer is 2 because the data set provided has a range of 2. Range is calculated by subtracting the smallest value from the largest value in the data set. In this case, the smallest value is 4 and the largest value is 8, resulting in a range of 2.

### Simpangan baku dari sekelompok data tunggal 7, 3, 5, 4, 6, 5 adalah …..

E.
Explanation
The correct answer is 1.14. The standard deviation is a measure of the dispersion or variability of a set of data. To calculate the standard deviation, we first find the mean of the data, which in this case is 5. Then, we subtract the mean from each data point, square the result, and sum up all the squared differences. Next, we divide the sum by the total number of data points minus 1, which is 5 in this case. Finally, we take the square root of the result to get the standard deviation, which is approximately 1.14.

A. 1,5
Explanation
The interquartile range is a measure of the spread of the middle 50% of the data. To find the interquartile range, we first need to find the first quartile (Q1) and the third quartile (Q3). Arranging the data in ascending order, we have 2, 2, 3, 4, 4, 5, 5, 6, 7, 7, 7, 7, 8, 8, 9. The first quartile (Q1) is the median of the lower half of the data, which is 4. The third quartile (Q3) is the median of the upper half of the data, which is 7. Subtracting Q1 from Q3 gives us the interquartile range of 7 - 4 = 3. Therefore, the answer is 3.

Explanation
The interquartile range is a measure of the spread or dispersion of the data. It is calculated by finding the difference between the upper quartile (Q3) and the lower quartile (Q1). In this case, the upper quartile is 6 and the lower quartile is 4. The difference between these two values is 2. Therefore, the interquartile range is 2.5.

• E.

2

D.
Explanation
The standard deviation of the data set 2, 4, 4, 5, 6, 6, 7, 8, 9, 9 is 2. This can be calculated by finding the mean of the data, which is 6, and then calculating the difference between each data point and the mean. These differences are squared, summed, divided by the number of data points, and then the square root is taken to get the standard deviation. In this case, the differences are -4, -2, -2, -1, 0, 0, 1, 2, 3, 3. The sum of the squared differences is 40, divided by 10 gives 4, and the square root of 4 is 2.
