Answer:

a = 5

Step-by-step explanation:

a  - \frac{2a}{5}  = 3 \\ 5a - 2a = 15 \\ 3a = 15 \\ a = 5

We multiply both sides by 5 before solving for a.

HELP!!<br> Which table is a probability distribution table?
fomenos

Answer:

Table 1 is the only table which represents PROBABILITY DISTRIBUTION table.

Step-by-step explanation:

In any given probability distribution:

1) The probability of each event should be strictly POSITIVE.

2) Sum of all events in a a distribution should be 1.

Now, here

A) All of the values of probability (0.11, 0..5, 0.49,0.35)  are positive.

Also, 0.11 +  0.5 +  0.49 + 0.35  = 1

So, the given table is a PROBABILITY DISTRIBUTION.

B)The table is NOT a PROBABILITY DISTRIBUTION as here

P(Blue) =  -1, which is negative.

C)The table is NOT a PROBABILITY DISTRIBUTION as here

P(Green) =  -0.49, which is negative.

D)The table is NOT a PROBABILITY DISTRIBUTION as here

P(Purple) =  -0.1, which is negative.

Hence, table 1 is the only table which represents  PROBABILITY DISTRIBUTION table.
