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
-5 + 4 = -1
start at -5 on ur number line....and since u r adding 4, move 4 spaces to the right and u should arrive at -1
Answer:
0.0306
Step-by-step explanation:
I don't know if there is any significance to both being drawn at the same time. I'm going to say there isn't.
The first draw gives
9/49
Their is no replacement. That's because both marbles are drawn together. The second draw is
8/48
P(both red) = 9/49 * 8 / 48 = 3/98 = 0.03061 which rounds to 0.0306
