Answer:

a) 30

Hope it's helpful to you

Answer 2

Answer:

Median = 30

Step-by-step explanation:

We have,

Mean = 30

Mode = 30

Median = ?

Now,

We know that,

Mode + 2 Mean = 3 Median

So,

30 + 2(30) = 3 × (Median)

30 + 60 = 3 × (Median)

90 = 3 × Median

Median = 90/3

Median = 30

Hence,

Median = 30

I shall also share a bonus trick with you to remember this central tendency formula.

If you already know it by Heart then, just leave it.

First we must write,

1 + 2 = 3

Now, remember the Central tendency Mantra,

"MoMe Meds"

Just think of it as a name of a pharmaceutical store that you own.

Now, just add the mantra into the numbers.

1(Mo) + 2(Me) = 3(Meds)

Now just expand it, as our formula,

1 Mode + 2 Mean = 3 Median

= Mode + 2 Mean = 3 Median

Hope it helped and believing you understood it........All the best
