Let be the side of the triangle and be the side of the square.
Let be the perimeter of the triangle and be the perimeter of the square.
We have the following relationship:
Which finally implies
Answer:
Side of triangle = 13 inches
Step-by-step explanation:
Let side of square be x inches.
Perimeter of square = 4*side = 4x --------->1
side of triangle = x+5 { the side of the triangle is 5 inches more than the side of the square. }
Perimeter of triangle = 3*side
= 3 * (x+5) =3x + 15 -------->2
The perimeter of an equilateral triangle is 7 inches more than perimeter of a square.
3x + 15 - 4x = 7
3x -4x = 7-15
-x = - 8
x= 8
Side of a square = 8 inches.
Side of triangle = x + 5 = 8 + 5 = 13 inches

Answer: Mean = 20 and standard deviation = 4
Let x represents the success of getting the correct answer.
Here, the total number of trials(n) = 100
The probability of getting the correct answer, p = 1/5
Thus, the mean of the number of correct answer,
Now, the standard deviation,
Thus, First option is correct.
