Total marbles: 1+ 4+3 = 8
Picking a blue marble = 4/8 = 1/2
Picking a second one: 1/2 x 1/2 = 1/4 probability
Answer:
c
Step-by-step explanation:

Answer:
7^x = 8
Step-by-step explanation:
log7 (8) =x
We know that loga (b) =c can be written as a^c =b
log7(8) =x becomes 7^x = 8
By dividing both numbers by 25, it will be 1/4
F(4z) = 3 * (4z)^2 - 6
= 48z^2 - 6
