Answer:
1/2(x²) square units
Step-by-step explanation
From the question,
Area of a Square(A) = L²
A = L²................. Equation 1
Where L = Lenght of the square
If the diagonal of the square is x,
Using pythagoras theorem,
a² = b²+c².................. Equation 2
Wherer a = x, b = c= L
Therefore,
x² = L²+L²
x² = 2L²
L² = x²/2
L = √(x²/2)
Substitute the value of L into equation 1
A = [√(x²/2)]²
A = x²/2 square unit.
A = 1/2(x²) square unit.
The right option is 1/2(x²) square units
Answer:
60
Step-by-step explanation:
The mode is the value which occurs the most in the set. We see that 60 occurs three times, 62 occurs once, 63 occurs once, 65 occurs twice, 66 occurs once, 68 occurs once, and 69 occurs once.
Thus, the mode is 60.

Answer:
The probability is 1/8 or 0.125.
Step-by-step explanation:
Given is that three fair coins are flipped.
And we have to find the probability of getting a head on the first flip,a tail on the second flip, and another head on the third flip.
Firstly, here each flip is independent of the outcome of the other flips.
So, the probability of head is 1/2 and the probability of tail is 1/2.
Therefore, the answer will be : (1/2) (1/2) (1/2)=8
