Answer:
ok so the probility of gettting one white fish is
13/23
and if we take out one white fish the problity is
12/22
so we just multiply
12/22*13/23=0.30830039525
so the problity is 0.30 if you choose two fish you will get white for both
Answer:
-81t^2 +16
Step-by-step explanation:
(9t-4)(-9t-4)
FOIL
first: -9t*9t = -81t^2
outer : -4*9t = -36t
inner : -4 *-9t = 46t
last = -4*-4 = 16
Add them together
-81t^2 -36t+36t+16
-81t^2 +16
Answer:4) 1. (3^4)^3=3^12 ,
2.(-10^3)^6=-10^18 others are similar...
5) 1. (2^7/2^5)=2^2,4 ,
2.(a^7/a^3)=a^4 ,
7. [(-4)^3 x (-4)^5)]/[ (-4)^2 x(-4)^3]=4^3 others are similar...
Step-by-step explanation: 4)1. step1. 3^(4x3) , 2. step1. -10^(3x6)
step2. 3^12 , step2. -10^18
5)1. step1. 2^(7-5) , 2. step1. a^(7-3)
step2. 2^(2) , step2. a^(4)
7. step1. -4^(3+5)/-4^(2+3)
step2. -4^(8)/-4^(5)
step3. 4^(8-5)
step4. 4^(3)
