C. 3/4
D. 1/4
Answers
HH,HT,TT,TH
As evident from above sample space,the probability of finding exactly one Head 2\4 I.E 1\2
so the answer is B
Option B. is correct.
What is probability?
Possible chances of occurring an event are known as the probability of that event.
Sample space for tossing two coins is :
( {H,H} , {H,T} , {T,T} , {T,H} )
Formula used:
Probability of an event =
Exactly one head appeared 2 times i.e., {H,T} or {T,H}
Thus, Favourable outcomes = 2
Total outcomes = 4
P (Exactly one head) =

The quotient equivalent to the expression is (5√x)/4.
Hence option B is the right choice.
How to find the quotient of an expression?
To find the quotient of an expression, we simplify the numerators and the denominators and then cancel off the like terms.
How to solve the question?
In the question, we are asked to find the equivalent expression to the quotient given by .
To find the equivalentexpression, we need to simplify the given quotient as follows:
{√(50x³)}/{√(32x²)}
= {√(25.2.x².x)}/{√(16.2.x²)} [Since, 50x³ = 25.2.x².x, and 32x² = 16.2.x²]
= {√(5².2.x².x)}/{√(4².2.x²)} [Since, 25 = 5², and 16 = 4²]
= (5x.√2.√x)/(4x√2) [Since, √(ab) = √a√b, and √a² = a]
= (5√x)/4 [Cancelling the like terms √2 and x].
Thus, the equivalent expression is (5√x)/4.
Thus, the quotient equivalent to the expression is (5√x)/4. Hence option B is the right choice.

The Perimeter: of the rectangular garden that has a width of 4x−6 and a length of 2x+4 is 2(2x - 7) + 2(3*2 + 4x).
What is perimeter?
Perimeter is the sum of length of the sides used to made the given figure.
The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
WE need to find the perimeter of a rectangular garden that has a width of 4x−6 and a length of 2x+4.
Area = (2x - 7) * (3*2 + 4x)
Area = (2x - 7) * (6 + 4x)
Area = 8x - 42

Answer:
y = 1/5x + 9/5.
Step-by-step explanation:
x = -3 + 5y - 6
5y - 3 - 6 = x
5y - 9 = x
5y = x + 9
y = 1/5x + 9/5.
Hope this helps!
