Mademuasel [1]

Answer: 4

Step-by-step explanation:

For any binomial variable X having parameters n (total number of trials ) and p (probability of getting success in each event), the standard deviation is given by :-

$\sigma=\sqrt{np(1-p)}$

As per given , we have

n= 100 , p= 20%=0.20

Then, the standard deviation of this binomial distribution is :

$\sigma=\sqrt{100(0.20)(1-0.20)}\\\\=\sqrt{100(0.16)}=4$

Hence, the standard deviation of this binomial distribution is <u>4</u>.

Answer:

surface area= 2261.95

volume=4423.36

Step-by-step explanation:

cone sa= 628.32

628.32*2= 1256.64

cylinder sa= 1005.31

1005.31+1256.64=2261.95

cylinder v=2412.74

cone v=1005.31

1005.31*2=2010.62

2010.62+2412.74=4423.36

please mark me brainliest :)

Answer:

$a=5m$

Step-by-step explanation:

$m=\frac{a}{5}$

Swap sides:

$\frac{a}{5}=m$

Multiply both sides by 5:

$\frac{5a}{5}=5m$

$a=5m$
