Assume that two marbles are drawn without replacement from a box with 1 blue, 3 white, 2 green, and 2 red marbles. Find the prob
1 answer:
Answer:
second marble is blue and first marble is white is
Step-by-step explanation:
given data
two marbles
box = 1 blue, 3 white, 2 green, and 2 red marbles
solution
we get here second marble is blue and given that the first marble is white
= P(3c1 × 1c1) ÷ P(3c1 × 7c1) ................................................1
= 1c1 ÷ 7c1
= 1 ÷ 7
so second marble is blue and first marble is white is

Area of a triangle = 
r = diameter/2
so area = pi * (13/2)^2
= 3.14*6.5*6.5 = 132.665
r = diameter/2
so area = pi * (13/2)^2
= 3.14*6.5*6.5 = 132.665
Answer:
x=
Step-by-step explanation:
Given:
This is a quadratic equation.
Taking common 3 from the equation given
⇒
dividing both side by 3
⇒
By using different factor, we can observe this trinomial can not be factored.
∴ solving it by completing the square.
⇒
adding 9 on both side
⇒
To get a perfect square number as coeffecient of x is 4, lets add both side by 4.
⇒
we know,
∴
Taking Square root on both side, remember; √a²= a
⇒
opening parenthesis
⇒
subtracting both side by 2
∴ x=
