There is no relationship between the grade level and the number of siblings each student has.
Explanation:
All the points are scattered
To be able to determine the type of skew exhibited by the distribution of the heights he achieved in each of his attempt we arrange the distribution in order and obtain the frequency of each data in the distribution. Height (meters): 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 Frequency: 2, 1, 1, 2, 2, 3, 1, 2, 1, 1, 1, 1, 1, 1 Calculating the mean gives (11 x 2 + 12 + 13 + 14 x 2 + 15 x 2 + 16 x 3 + 17 + 18 x 2 + 19 + 20 + 21 + 22 + 23 + 24) / 20 = 335 / 20 = 16.75 Since there are more higher frequencies to the left of the mean we conclude that the distribution exhibits a positive skew.
In step 3, you added 8x onto the other side instead of subtracting it from 15x.
The Length of the Given Sign = 90 inches
The Side of the Triangle can be found by Pythagorean Theorem
⇒ (Side of the Triangle)² = 40² + 30²
⇒ (Side of the Triangle)² = 1600 + 900
⇒ (Side of the Triangle)² = 2500
⇒ (Side of the Triangle) = 50
⇒ Perimeter of the Given Sign = (4 × Side of Triangle) + (2 × Length)
⇒ Perimeter of the Given Sign = (4 × 50) + (2 × 90)
⇒ Perimeter of the Given Sign = (200 + 180) = 380 in
