Answer:
n = 288
Step-by-step explanation:
18 sqrt(8) - 8 sqrt(18) = sqrt(n)
18 sqrt(4*2) - 8 sqrt(9*2) = sqrt(n)
We know that sqrt(ab) = sqrt(a) sqrt(b)
18 sqrt(4) sqrt(2) - 8 sqrt(9) sqrt(2) = sqrt(n)
18*2 sqrt(2) - 8*3 sqrt(2) = sqrt(n)
36 sqrt(2) - 24 sqrt(2) = sqrt(n)
12 sqrt(2) = sqrt(n)
Square each side
(12 sqrt(2))^2 = (sqrt(n))^2
12^2*(sqrt(2))^2 = n
144 *2 =n
288 =n

Answer:
Step-by-step explanation:
1) i think for the first question any probability greater than 0.4 has more likelihood that it will happen
2) mutually exclusive events are ones that cannot occur at the same time as it's impossible e.g. a single coin toss cannot result in you getting heads and tails
Answer:
14
Step-by-step explanation:
Since the volume of a prism is length*width*height, and the width is 3 and the height is 5 and the volume is 210, you get the equation 3x5x length=210. Solving it, you get length=14.
<em>when we solve the equation it will become
x</em>² + 9x<em>= 0
now here a = 1 , b = 9 and c = 0
by using quaderatic formula
x = -b +,-</em>√<em>b </em>²<em>- 4ac / 2a ( 2a is divided by all terms )
by putting values
x = - 9 +,</em><em>- </em>√<em>81 / 2(1) ( </em>√<em>81 = 9)</em><em>
x = -9 + 9 / 2 and x = -9 -9 /2
x = 0 and x = -18 /2 = -9
now there are two values for x one is- 9 and other is 0
so we put -9 as the value of x then answer will be zero..</em>
