Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

Answer:
0.0909 = 9.09%
Step-by-step explanation:
Initially we have a total of 12 socks, where 4 are green, so the probability of grabbing a green socks is 4/12.
Then, as there is no replacement, we have 11 socks, where 3 are green, so the probability of grabbing again a green socks is 3/11
So the probability of both socks being green is:
P = (4/12) * (3/11) = 1/11 = 0.0909 = 9.09%
Step-by-step explanation:
a×10⁰×a
<em>Since,</em><em> </em><em>m⁰</em><em>=</em><em>1</em><em> </em><em>therefore</em>
a×1×a
a²
Answer:
-6x+5
Step-by-step explanation:
(-5x+4)+(-1)(x-1)
-5x+4-(x-1)
-5x+4-x+1
-5x-x+4+1
-6x+4+1
-6x+5
They would be 128 years old. Now that is old!
