G = number of green = 7
S = number of striped = 8
T = number total = 10+7+8 = 25
probability of picking green = P(G) = G/T = 7/25
probability of picking striped = P(S) = S/T = 8/25
P(green and striped) = P(G)*P(S) ... events are independent
P(green and striped) = (7/25)*(8/25)
P(green and striped) = (7*8)/(25*25)
P(green and striped) = 56/625
P(green and striped) = 0.0896
--------------------------------
In summary, the answer as a fraction is 56/625
In decimal form, the answer is 0.0896
The value 0.0896 can be converted to percent form to get 8.96%
Answer:
whole number = 8
fraction = 1/8
1/8 * 18 = 18/8
Step-by-step explanation:
fraction times a whole number = 18/8
1/8 * 18 = 18/8
The equation for which square method is possible is x²-8=1
Step-by-step explanation:
For checking which of the equation satisfies the complete square condition, we proceed by checking each of the available options
1). x²+20x=52
Rewriting it as x²+20x-52
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 1) and independent constant (i.e. 52) is not a perfect square.
2). 5x² + 3x = 9
This equation can be rearranged as 5x²+3x-9=0
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 5) and independent constant(i.e. 9) is not a perfect square.
3.) x² −8=1
This equation can be rearranged as x²=9
Hence x= ±3
This binomial expression is a perfect square and can be done by the square method.
4). 3x² −x+17=0
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 3) and independent constant(i.e. 17) is not a perfect square.
