(5 + 16) / 7 + 3^2 - (1 + 3)

8

Step-by-step explanation:

(5 + 16) / 7 + 3^2 - (1 + 3)

21 / 7 + 3^2 - 4

21 / 7 + 9 - 4

3 + 9 - 4

12 - 4

8

Use PEMDAS.

P - Parenthesis

E - Exponents

M/D - Multiply/Divide

A/S - Add/subtract

So for this:

Start with parenthesis: (5+16) and (1+3), so 21 and 4

Then exponent: 3^2, which is 3*3 which is 9

Then divide: 21/7 is 3

And then the rest: 3 + 9 - 4. 3+9 is 12, 12-4 is 8, so you're answer is 8.

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2
