Answer:
Step-by-step explanation:
- 2·
+ 20 = 32 - 2· = 12
- = 6
- (v + 4) log 4 = log 6
- v + 4 = log 6 / log 4
- v + 4 = 1.29 (<em>rounded</em>)
- v = 1.29 - 4
- v = - 2.71
Answer:
x=9
Step-by-step explanation:

20:30: Divide both of them by 10
=2:3
2 x 12:3 x 12
24:36
Hope this helps!
Answer: B. one-third
Step-by-step explanation:
Probability of picking a red marble, P(R) = 1/6
Probability of picking a yellow marble, P(Y) = 1/2
Therefore, the probability of picking a blue marble will be:
= 1 - (P(R) + P(Y))
= 1 - (1/6 + 1/2)
= 1 - (4/6).
= 1 - 2/3
= 1/3
The probability of picking a blue marble will be one third
